In addition to humiliation, roast duck, roast pork…Lang Son also has a rustic dish with the mountain flavor of the Tay people, which is wild shrimp.

Lang Son shrimp has a similar shape to a shrimp but is small in size and has locust-like legs. Photo: Vietnamese people. Considered as a seasonal specialty, Lang Son forest shrimp costs up to 500,000 VND/kg at the beginning of the season. In the middle of the season, wild shrimp are cheaper, about 300-350,000 VND/kg. Photo: Vietnamese people. According to local people, wild shrimp are available around June and July. At night, this insect flies out in all directions to feed, during the day it stays in the nest. Photo: People of Vietnam To catch wild shrimp, people have to go quite far because the deeper in the forest, the more wild shrimp there are. Sometimes we have to cross hills and mountains to deep forests. Photo: Youtube However, wild shrimp are very smart, knowing that someone is approaching, they run away. The catcher must have experience to catch all the nests. Photo: Youtube Due to the high selling price, in the season, many people go to the forest to catch wild shrimp to sell to earn extra income. Wild shrimp are often processed as a drink by roasting with ginger leaves, lemon leaves or guise leaves, leaves of magnolia.

According to scientists, the reason farming has to use Neonicotinoids is to combat the many predators that are ready to pounce on corn or soybean seeds, every time they are sown in the ground. Seeds are impregnated with drugs before sowing. Photo: Scientific Beekeeping What are neonicotinoids? Neonicotinoid has been banned for use in Australia and Europe since 2013. This is a pesticide derived from nicotine (the addictive substance found in tobacco), the way to use is to dissolve in water and spray on plants. for the plants to absorb themselves, forming an artificial “immune system” to protect the crops. Neoincotinoids are thought to be effective against pests and insects, but are safe for mammals. However, because of its strong effect on insects, it also affects bees directly, reducing the number of pollinators. This pesticide is said to reduce the sperm count of male bees by up to 40%, as well as reduce their lifespan from an average of 22 days to 15 days, thus reducing the chances of male bees fertilizing the queen bee. also decreased. Besides disease, soil-dwelling pests such as helminths and larvae can also damage seeds and seedlings, along with terrestrial insects such as bean leaf beetles and aphids. seeds and saplings. Therefore, in the field of seed treatment against insects and diseases, farmers often treat seeds in combination with fungicides (IST) to help plants sprout straight and grow early. It is easy to mention some of the popular Neonicotinoid IST methods such as Imidacloprid (Gaucho, Bayer Crop Science), Clothianidin (Poncho, BASF) and Thiamethoxam (Cruiser, Syngenta)… Seth Naeve, an agronomist specializing in soybean research at the University of Minnesota Extension (USA), said that Neonicotinoid insecticides are highly water-soluble, helping to activate protection from insects. Great early season. Shawn Potter, Syngenta’s head of seed care product marketing, said that the growth of the seeds after treatment was driven in part by previous seasons. “Early seeding from a wet, cool, or both, seeds and seedlings will be exposed to various diseases. “Without seed treatment, crops could be damaged early on,” said Mr Potter. Nick Tinsley, BASF technical specialist, added: “Farmers and retailers alike can easily treat corn and soybean seeds with Neonicotinoid insecticides as well as fungicides from the company. producers to protect crops”. For decades, seed companies have treated corn with fungicides. However, IST only started to be added to the fungicide seed treatment of soybeans in the early 2000s. Studies have demonstrated that a combination of seed treatment with both fungicides and insecticides increases soybean yield per acre by 2 bushels (equivalent to 72.74 kg/0.4 ha). According to Mr. Potter, in general, each “shift” of treating soybean pest/mushroom combos will cost from 10 to 12 USD per seed unit (ranging from 80,000 to 140,000 seeds/0.4 ha). That’s because 70% of treatment costs go to pesticides, while the profit-taking rate per acre is between $16 and $17. This assumes that soybeans cost $12 per bushel and that the cost of the pesticide seed treatment is between $7 and $7.50 per seed unit. Entomologists in the Midwest and South America have also observed that the average soybean yield spike of 2 bushels per acre from this combination. “Some years are higher, some years are lower,” says Sebe Brown, an entomologist at the University of Louisiana. Responses tended to be higher in cases where soybeans were planted early, two crops, or planted after a cover crop.” Gus Lorenz, a scientist at the University of Arkansas, adds: “Companies have provided growers with insurance to maintain good standing. At current seed prices, the cost of treating seeds with pesticides is a good investment.” A synthesis of studies in a 2019 report representing agronomists and entomologists from 14 universities found that the best recorded soybean yield was an increase of 3.3 bushels per acre. after using the combined seed treatment solution. However, in some cases in Minnesota, the benefits are so small that it is argued that farmers should not be encouraged to use seed treatments or should apply them selectively. Concerns Previously, scientists believed that neonicotinoid pesticides were the main cause of the decline in bee populations and pollinators worldwide. A few years ago, the United Nations published alarming figures: In the first 10 years of the 21st century, the number of bees in the world has decreased by 85% in the Middle East, about 30% in the US and Europe. Neonicotinoids are likened to “birth control pills” for bees and reduce the population of bees. Photo: GCM Bees are the intermediate species that help pollinate more than 75% of the world’s food and fruit crops, so a decrease in the number of bees also means a reduced crop or even a crop failure. However, long-term studies by Syngenta suggest that the health effects of bees are negligible when using Neonicotinoid seed treatments to kill insects. According to Mr. Potter, what many experts agree on is that the health of bees depends on the interaction of factors such as parasites, disease, nutritional health and weather phenomena. A 2019 study published in the journal Scientific Reports detailed the effects that imidacloprid had on white-tailed deer. When imidacloprid (an insecticide that acts as an insect CNS toxin, belonging to the genus Neonicotinoids) was increased in the animal’s spleen, factors such as progeny viability, length of jawbone, body weight and visceral weight all decreased. Records show that at least 60% of white-tailed deer killed indicate the presence of Imidacloprid. According to expert Jonathan Lundgren, all insecticides can negatively impact mammals and bees. “The use of insecticides is so widespread these days that they are present in almost every growing system across the United States and are truly binding. These insecticides are affecting ecosystems in ways that we could not have foreseen.” Meanwhile, the companies that manufacture and trade in Neonicotinoid seed treatments have always denied this and asserted that “the products are safe if used according to the instructions on the label”. Compounds such as polymers coat the seeds or products like Bayer Fluency Agent Advanced to help prevent release into the environment, said Chip Graham, Bayer Crop Science’s North American director of seed development. “Initially we had really low dust levels, but these products ensure that pesticides remain on the seeds and reduce contamination levels during the growing process,” said Mr. What is the future of farming? Instead of treating seeds with neonicotinoid insecticides, Mr. Lundgren called for regenerative methods, such as tilling and changing seasons, increasing crop diversity as well as reducing pest pressure. bugs, insects. “Farmers need to understand that these seed treatments really don’t help them much,” said Lundgren. Neonicotinoid pesticides are believed to reduce bee pollinators, threatening food security. Photo: TN Meanwhile, expert Graham said that banning this seed treatment would be detrimental to farmers because “there are currently no foliar sprays to treat early-season insects as a rescue application”, so ” Seed treatment in this way is most effective to provide activity against early-season pests of maize and soybean.” Agronomist Naeve said: “They’re a good example of how the best tools we’ve ever had in agriculture, but it’s not a good idea to treat the entire soybean acreage. They can be a double-edged sword.”

The sugarcane beetle species mainly include the black scarab, the brown beetle and the large brown hairy beetle, which often arise and cause strong damage in sandy soil, riverbank soil, soil with light mechanical composition, or on specialized cultivation areas, growing sugarcane for many years, not rotating crops with other crops. NASU technicians check for insects entering the lamp trap. Photo: NASU. The life cycle of these beetles lasts from 365 to 720 days, going through 4 stages: egg, larva (worm), pupa and adult. Over the years, Nghe An Sugarcane Company Limited (NASU) has researched and applied integrated measures to effectively manage sugarcane beetles in the company’s raw sugarcane areas. This is the result that NASU has studied the management of sugarcane beetles in many countries such as China, Thailand, Indonesia… to apply on NASU’s sugarcane material area. Mr. Nguyen Hoang Son Phong, engineer of NASU said that sugarcane field was damaged by beetle larvae, yield decreased by 13-54%, sugar decreased from 11-57%. The original cane is more severely damaged by beetles than silk cane. Larvae (larvae) hatch from eggs, live in the soil for an average of 240 – 480 days (larvae of the brown hairy beetle are larger, longer than the beetle species) before transitioning to the pupa and adult stage. During the development cycle, larvae are active in the ground, age 1 and 2 in addition to eating cane roots, also eat organic matter, humus, decayed organic fertilizer or bagasse. Light traps are quite simple but effective in killing beetles applied in the cane material area of ​​NASU. Photo: NASU. From the end of the age of 2, the larvae only feed on the roots and underground stems of sugarcane. The 3-year-old larvae have a long sexual development time and cause the most damage to sugarcane, making sugarcane unable to grow, withering, drying and dying, leading to a decrease in sugarcane and sugar yield. The more damage the harvest stage, the more obvious. When the 3-year-old larvae are full, they begin to build cocoons out of soil and pupate to stay in the cocoon. If the weather conditions are favorable, after about 20 days, the pupae will turn into an adult, break the cocoon and crawl to the ground. Unfavorable weather conditions, especially low soil moisture and low temperature, will prolong the pupal development time. This extended period, called the hibernation period, can last up to 4 months. Effective management of beetles According to the research as well as the process applied effectively at NASU, control beetle larvae by plowing the soil thoroughly before planting sugarcane, collecting larvae and spreading the granular insecticide Patox 4GR, with the amount of 40 kg/ha in rows when planting sugarcane. Beetles trapped in nets. Photo: NASU. However, the method of spraying granular pesticides into the soil, in addition to killing larvae, will destroy beneficial microorganisms and insects in the soil, affecting the soil environment. The adults of these sugarcane beetles tend to be strong with light, fly out to mate from March to May, after showers with an amount of over 20mm. This is the best time to kill adults, limit egg laying, and reduce later harm caused by larvae. Mr. Hoang Quoc Tiem, a long-time sugarcane grower in Dua village, Nghia Yen commune (Nghia Dan, Nghe An) said that in the spring crop of 2021, in addition to killing larvae when growing sugarcane, NASU has implemented additional measures to destroy them. maturity such as using lamp traps, casting nets, and making traps in the field. The light trap is designed to be able to install light bulbs from the grid, battery lights or solar power systems. Traps are made by taking advantage of plastic containers, above are lights, below are placed water, add diesel oil to prevent the adults from moving out of the trap. In the middle of the light trap, install 2 corrugated iron sheets of size 40 cm x 60 cm, perpendicular to each other. As adults, beetles are attracted to light, flying into traps will collide with corrugated iron and fall into the water. After the rainy nights of early summer, each light trap catches 250-300 brown beetle adults, 40-50 black beetle adults, and 20-30 large brown-haired clipping adults and lots of adults of other sugarcane borers. The “product” obtained after a night of light traps includes many different species of beetles and borers… Photo: NASU. In addition, on the field, a fishing net is installed, the size of the net is 1cm x 1cm, and the adults move hundreds of fish of all kinds after every night it rains. In the sugarcane field, from 50 – 100m, dig pit traps, measuring 30 cm deep x 60 cm long x 60 cm wide, below the manure and by-products, which are the preferred food of adults, mixed with drugs. Low-odor insecticide is Goldra so that when adults eat it, it will be destroyed. According to the research results of scientists, the female beetle species can lay an average of 229-328 eggs, the lowest hatching rate from eggs to larvae is 70%. With the method of killing adults from light traps and netting in the field, it will limit a lot of harm caused by larvae to sugarcane … Mr. Phan Van Toan, Director of Agricultural Extension of Nghe An Sugar Co., Ltd. said that with the above management method, the rate of damage of beetles on both silk and sugarcane fields is reduced. This is the money for the company to expand the model on the raw material area in the coming years to stabilize the material area and improve production efficiency for farmers.

Illustration. For ants and small animals, the resistance of the air helps them a lot and makes their falling velocity very slow, sometimes their acceleration is negative (due to the wind blowing up). Thus, ants are almost unharmed when falling from the roofs of high-rise buildings. All objects falling through the air have terminal velocities that depend on their size, shape, and mass. The terminal velocity of an ant (6.4 km/h, according to the physics department of the University of Illinois) would be vastly different from the terminal velocity of a human (about 200 km/h). “For rats and any small animal, there’s really no danger. You can drop a rat into a minehole nearly 1,000 meters deep and when it hits the bottom, it’ll be slightly stunned and run away. , provided that the ground is fairly soft.The air resistance acting on a moving object is proportional to its surface.If the length, width and height of an animal are divided by 10, respectively, the mass is its mass is reduced by 1000 times while the surface area is reduced by only 100. Therefore, the air resistance for small animals is usually 10 times higher than the driving force. Force isn’t usually a problem for an insect, it can be free-falling without danger, with the ability to grip.” Michael Kaspari is an ecologist at the University of Oklahoma (USA) who has studied the aerial activities of wingless ants. Research shows that when ants are facing a predator, they will jump right into the air from tall tree branches and use their legs to control the direction of flight to reach the tree trunk. The longer hind legs will help the ants glide through the air, helping them avoid falling into places they consider dangerous. With this ability, it is possible that the ant has found a way to cling somewhere before it falls to the ground, but whether or not the ant does, the ant will not die if it hits the ground. The most ancient creature that still exists to this day It is said that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to the biological kingdom, it is estimated that ants account for 15-20% of the total number of animals living on land. Ants are animals belonging to the order of membranes, the class of insects. Scientist Corrie Moreau and French colleagues published a study showing that ants appeared between 140 and 170 million years ago. That means they are the most ancient creatures that still exist to this day, despite the violent fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survivability is endowed by nature, for they show no sign of changing accordingly. Which means it’s very likely that an ant 170 million years ago and an ant today would be no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are present everywhere on earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the color is usually just red or black. Especially, there are new species mixed with white color. Ants are gregarious species, with a rather distinct social organization. Each ant nest has an average of about 100,000 children in a colony with a single mother (Christian ants can live up to 30 years). Here, there is something like the organization of a swarm life of bees. The vast majority of ants in the colony are worker ants (who only live for 1-2 years) – likened to the hardest workers on earth. The job of worker ants is to take care of the queen, incubate eggs, transfer eggs, raise baby ants, build burrows, find food, guard … Not many people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become a god, but are forever just “cool” feet from birth. until death. Ants are considered to be the strongest species because they can carry food 10 times heavier than themselves. But to transport that heavy amount of food, they must use collective strength in coordination. Together they carry the food they earn very easily, when thousands of them work together. Ants are everywhere, everyone can see them or be bitten by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as a tool to heal wounds. When a member of the tribe is injured, they will catch a few large ants in the swarm of “army ants” so that they bite on both sides of the wound, then remove the ant body, leaving only the ant head on the wound. Since then the wound does not bleed and heals quickly. And interesting things about ants Ants are animals with a fairly hygienic life. Specifically, the handling of dead animals. When one ant dies, the other ants in the colony will together carry the dead ant out of the nest, with the sole purpose of keeping it clean and avoiding infection or disease spread. The workers will take care of the carrying, under the command of an ant that is supposed to be in charge of the burial of the colony. It is also surprising to learn that ants are insects with very advanced organizational systems. Along with the Lord ant, worker ant, and burial commander ant, there are also ‘teacher ants’ Born, in order to have the necessary skills, they undergo a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In case the “student” learns slowly and “fails” in the test, they will be transferred to another job that requires less skill. Not only know how to find termites, but ants also know how to “livestock” to create food reserves. They feed on insects such as aphids and caterpillars to obtain the sweet substance secreted by these insects. When it’s time to harvest the sweetener from the insect swarm, the ants “milk” using their antennae. It is very interesting to know that ants bring with them the insects they nourished when they move to a new area. It’s no different than people taking livestock with them to more verdant places. People have talked about the extraordinary in the world of ants. They have no ears but perceive sound from ground vibrations, through sensitive sensors on the pins. They have the ability to exist to the point of fantasy despite the harshness of weather and climate. Therefore, ants are also one of the first creatures on earth to be sent into space by humans in an experiment to conquer the sky. Ants have poor eyesight, but they often use the earth’s magnetic field to navigate. They are considered the most intelligent insects when in the small head of ants there are more than 250,000 brain cells. As industrious animals, ants are also said to be “excellent athletes”. If an ant were about the same size as a human, they could run at an average speed of 55 km/h without ever getting tired. They are also able to lift an object 50 times its own weight with extraordinary strength.

Many diners enjoy this dish with the outdoor space on the terrace of the restaurant in Paris, praising the food that is quite new to the European region. The ornate dish won many nods and compliments from the adventurous clientele. A chef from Paris who has just prepared a pasta dish of insects, sweet potatoes and sautéed larvae, said: “This is an ideal dish for beginners to eat insects. Their taste is quite attractive and very little. who don’t like it.” French restaurant serving food of the future is not for the faint of heart In January 2021, the European Food Safety Authority (EFSA) deemed the larvae of the beetle, Tenebrio molitor, fit for human consumption. By May 2021, this agency approved the sale of this ingredient in the food market. It is predicted that to meet the growing world population, insects will soon be included in the cuisine of the future. The European Food Safety Authority has studied more than a dozen different applications for insect food products, including crickets and locusts. Insects in general can provide a sustainable and low-carbon food source for the future. Local resident Soheil Ayari, after dining with her two daughters, said: “I feel like I’m in a traditional restaurant except for what I’m eating. But honestly, the taste is very good. like regular food”. Ayari’s young daughter is also very excited about the new dish, saying: “Insects are eco-friendly and more than that, they are also very good.” Laurent Veyet raises worms at the store, their food is porridge and vegetables. Although, at first glance, the larvae look like maggots unappealing to enjoy, they are in fact the larvae of beetles, which are rich in protein, fat and fiber. With a versatile ingredient, the beetle larvae can be used to cook curries, salads, or ground to make flour into pasta, cookies or bread. Stefan De Keersmaecker, spokesman for health and food safety at the European Commission said: “Insects are very nutritious. They really help us transition to a healthy diet and food system and more sustainable”. For chef Laurent Veyet, he faces a two-part challenge. It is about winning public opinion and learning how to create attractive insect dishes combined with a variety of foods. “You have to find the right flavors and the right accompaniments. That’s what any chef will tell you,” says Laurent Veyet.

Khanh Hoa newspaper reported, after more than 1 year appearing in Khanh Hoa, Japanese gourd proved to be very suitable and a good choice in the process of crop transformation of farmers. Mr. Paul Edward, Director of Capsi Food Company Limited – an enterprise that has planted 340 Japanese gourds, said: After nearly 2 months of planting, the trees have started to bear fruit. Each string can bear fruit continuously for 6 months. In total, one life cycle, one gourd gives 8-12 fruits, each weighing from 9-12kg. Not only in terms of productivity, in terms of proper care and technical process, the quality of the gourd is large and round. The gourd weighs 9kg. (Photo: Khanh Hoa Newspaper) After harvesting, the enterprise will process the gourd by cutting it into 3mm thick and 3cm wide strips, then dried and packaged. Part of it is sold to the domestic market, while most of it is exported to Japan and China. Country. Dried gourd fiber is used in cooking. It is expected that the domestic price of dried gourd fiber can reach 1 million VND/kg. Unique style of ‘putting money in a bucket, getting things in a pot’ during Covid-19 Nguoi Lao Dong Newspaper reported that, in the face of complicated developments of the Covid-19 epidemic, many home-based small businesses in the 7.2 ha temporary market in Vinh Phuc (Ba Dinh, Hanoi) have devised a way to put food in. The buyer then puts the money in the bucket next to it to limit contact and crowd gathering. People who come here to buy goods must stand behind the barricade, not be in close contact and must keep a minimum distance of 2m. Disinfectant water is placed in front of the door by many home-based small businesses for guests to use. Strange dish ‘crawfish on the tree’ of the people of Lang Speaking of Lang Son cuisine, in addition to humiliation, roast duck, and roast pork, there is also a rustic dish with the taste of the mountains and forests of the Tay and Nung people, but not everyone knows it, which is “forest shrimp”. According to Dan Tri newspaper, this strange dish is delicious, but the price is quite high, about more than 300,000 VND / kg and not always available. “Forest shrimp” clinging to trees. Called “forest shrimp” because this species has a similar shape to shrimp but belongs to the insect family. “Forest shrimp” has a small size, which is as big as an adult’s little finger. This species has locust-like legs, the whole body is gray in color, slightly pale. It is from their strange shape and habit of preferring to live in places with a humid climate, dense trees, or shelter in large tree holes that only exist in the deep forest that people give them a strange name. wild shrimp”. The sticky rice shop has a weird name but the food is absolutely delicious This sticky rice shop has the real name Xoi Man, but most customers call it “sticky rice mortuary”. Explaining the strange name, Mr. Luu Bao Minh, the owner of the sticky rice shop, shared on GiadinhNet: “In the past, the restaurant was located on the corner of Nguyen Tri Phuong and Tran Phu streets, but since moving here, it is located near funeral homes and shops. Selling boxes, funeral services, hospitals, so the restaurant is named like that. The sticky rice shop is a car with a glass cabinet that looks like a bread cart that is often seen on many streets in Saigon. The pot of sticky rice is mounted on a gas stove placed in the car, the sticky rice is always smoky. The shop only sells salty sticky rice. In addition to the main ingredients, which are sticky rice, sausages and cotton balls, there are also onion fat and fried onions to create aroma and round taste. Another plus point is that the shop sprinkles more crushed peanuts, creating a strange taste because salty sticky rice is rarely used by this ingredient. Another interesting thing is the unique way of eating, sticky rice will be wrapped in fresh banana leaves into long rolls like Tet cakes. Where guests eat, tear the banana leaves there, absolutely do not use a spoon. Strangely, banh cuon filled with broth in Cao Bang If the light rolled in many places is just a layer of powder coated, added inside with meat, wood ear dipped with fish sauce, Cao Bang rolls are completely different, served with a bowl of bone broth. Cao Bang people consider banh cuon eaten with bone broth as a specialty, a rustic breakfast gift for generations. When eating, the cake will be submerged in a bowl of soup with a little chili, sour bamboo shoots. Instead of sweet and sour fish sauce, Cao Bang rolls are eaten with clear bone broth with chili and bamboo shoots soaked in honey, so this dish is also known as “banh cuon soup”. This is a way to distinguish it from other regions such as banh cuon Phu Ly (Ha Nam), banh cuon Thanh Tri (Hanoi). The farmer who planted a strange jackfruit seed did not get enough fruit to sell According to Dan Tri newspaper, old farmer Nguyen Minh Trang (70 years old, in Vi Dong commune, Vi Thuy district, Hau Giang province) is known as the “father” of the red-fleshed jackfruit tree in the region. Mr. Trang was the first to bring this strange variety of jackfruit to the locality to plant, and also a seller of jackfruit seeds to his relatives. This type of jackfruit has brick red citrus, sweet taste, both chewy and crispy. On an area of ​​1.5 hectares of jackfruit is being harvested, each month Mr. White can collect up to 4 tons of fruit. Because the price of jackfruit is very high, at 70,000 VND/kg, Mr. White can pocket up to 3 billion VND each year. Ca Xiu – a unique specialty only in Kien Giang Ca Xiu is a unique specialty in Ha Tien (Kien Giang). According to Knowledge and Life, the appearance of ca Xiu is quite similar to bivalve seafood, but also like insects with long and large antennae. Diners, when they see the coffee bean, have a feeling of fear, not daring to touch chopsticks. Ca Xiu is a unique specialty in Ha Tien (Photo: IT) Not only has a fancy shape, this dish also makes people curious about its taste. When catching Ca Xiu, people bring salt similar to the three-knot salt. From salted coffee, people have created many delicious and attractive dishes. Strangely, the market in Yen Bai is priced at 5,000 VND According to the Vietnam Agriculture Newspaper, the “5,000” market is located along Highway 32 from Van Chan to Nghia Lo town, Van Chan district, Yen Bai province. Here, the highlanders sell agricultural products and local products at the price of 5 thousand VND. According to longtime traders, the market has been established for more than ten years. Because it has no name and has not been planned as a people’s market, people and passersby call it a 5,000-dollar market or a one-price market. Market 5 thousand is not only meaningful in terms of commerce but also a cultural address that attracts tourists near and far because of the simple, rustic and genuine human factors here.

Chef Bun Lai’s cicada sushi invites Washingtonians to enjoy it for free on May 23. Photo: AP Accordingly, the number of cicada species “Brood X” has emerged from the ground for the first time since last weekend after 17 years hidden deep underground. The largest population of cicadas is believed to be in the eastern states of the United States such as Maryland, Pennsylvania, Virginia, Indiana and Tennessee. With this in mind, a chef in Washington DC took the initiative to “take advantage” of this rare insect invasion as an opportunity to show off his talent for processing cicadas into a new dish. Hong Kong-born American chef Bun Lai said his actions fit an aspect of food ethics. Accordingly, chef Bun Lai, a supporter of the sustainable food movement, invited locals to go catch cicadas in city parks, then prepare and invite them to enjoy fried cicada sushi made by himself. he created. This chef also teaches people how to catch, prepare and prepare dishes from cicadas as a way to talk about alternative food sources. Fried cicadas and wrapped with rice with vegetables. Photo: AFP “In a world where humanity is suffering from a multitude of diet-related diseases – we will have to take a revolutionary approach to eating habits,” said Bun Lai. On his personal tweeter, the chef constantly “invited” Americans to go hunting cicadas and enjoy free dishes from this “nearly 20 years old” insect. Stella Roque, a 36-year-old local resident who grew up with a fear of all insects, said she wasn’t too eager at first but took the opportunity to overcome her phobia. “I came here today because of Bun Lai’s invitation to try cicadas over the fire, and I thought it would be an interesting experience. I decided to join the event because I had previously heard about the mysterious day of the cicada “Brood X” occurring in the area.” Chef Bun Lai and local people catch cicadas that have just escaped their bodies to be processed into dishes. Photo: AFP Magazine The Washingtonian In the end, she’s not alone in trying out some of the macabre dishes, and hopes cicadas will become a staple on restaurant menus. Responding to the press, chef Bun Lai happily warned not to let cicadas become “food for gourmets”, for fear that they would be “slaughtered” for food like humans did. with so many species that we’ve been obsessed with. Under the guidance of chef Bun Lai, the harvested cicadas are washed and salted before being fried in a pan and turned into sushi along with rice and vegetables. This cicada dish is gluten-free, high in protein, low in fat and macronutrients (carbs), the chef says. After enjoying the cicada sushi, Ms. Stella Roque said: ‘I was expecting the worst, but then I was “pleasantly surprised” by how delicious it was. An American citizen enjoys cicadas cooked into sushi at Fort Totten Park in Washington DC on May 23, 2021. Photo: AFP Brood X cicadas are creatures that spend 17 years living underground, unlike other breeds with a life cycle of 13 years. They suck the sap of tree roots for food but do not harm people, except make noise. In their 17th year they will emerge from the ground in billions, if not more. According to entomologist Michael Raupp, cicadas have come to the surface earlier in recent years because of climate change. In the pre-1950s, they usually appeared at the end of May, but now they appear a few weeks earlier.

Illustration. Powdered caterpillars are rich in protein The mealworm is a species of beetle in the family Tenebrionidae, known in English as Mealworms or mealworm beetle. In 1758, Linneus gave the scientific name Tenebio molitor. This species is native to Europe, is on the list of storehouse pests (cereals, flour and food), but is not serious. In Vietnam, mealworms are considered to originate from the Mediterranean, but are mainly imported from China through informal channels and considered as “strange weeds” (foreign creatures) with the name “Golden mealworms”. Powdery mildew larvae are widely sold in Hanoi and used as food for ornamental birds. Insects for animal and human food have received increasing attention in recent years. They may represent an alternative source of protein and micronutrients compared to conventional meat sources. Therefore, the objective of this work was to determine the nutritional value as well as the degree of chemical and microbiological contamination in order to better assess the risk/benefit of consuming mealybug larvae. These mealworm larvae have a nutritional value with 10.4% fat and 13.7% protein, similar to conventional meat sources. Their main fatty acids are oleic (37.8%) and linoleic (33.2%). The results showed that these larvae met the essential amino acid requirements (all above 100% of the daily contribution), with the exception of lysine. Study results also show that T. monitor larvae are an excellent source of minerals such as phosphorus, magnesium and zinc (114%, 109 to 128% and 117% of the RDI). Although, it is low in potassium and iron (16-17% and 20% of the RDI). The lower sodium content is a health advantage, as eating a lot raises blood pressure. The mercury and lead values ​​were below the detection limit and the cadmium level was 0.10 mg/kg. The larvae of mealybugs had a high amount of bacteria but no pathogenic bacteria were detected. Starving the larvae for 8 days at 5°C reduced the total number of microorganisms, especially yeast, and the total number of thermophilic anaerobic spore forming bacteria. Licensed by Europe as food Recently, the European Union Food Safety Authority (EFSA) announced that it has granted a safety certificate for the consumption of dried yellow powder worms. It paved the way for restaurants in the area to offer insect-based foods. The EFSA’s first approval of a food insect is a big step forward in helping insects find a “place” in the daily menu of people. This is the basis for EU officials to decide whether to allow the sale of this item in 27 countries in the region. The new decision also marks the first time the safety assessment process for an insect food has been completed by EFSA, as the agency aims to license the protein-rich food industry. Currently, in Europe, insects are still not on people’s menus. Because of psychological and cultural issues, different from the reality in some Asian countries such as Thailand, Cambodia, Vietnam, Hong Kong, China… However, with this decision, the industry expects the insect food market in Europe to grow rapidly in the coming years, reaching an output of 260,000 tons by 2030. Not only flour worms, rice worms (Zophobas morio) will probably not be far away from taking over all nutritious foods such as chicken, beef, pork, milk… to become the main source of protein for mankind. Future. Rice worm farming accounts for only 10% of the land area compared to cows, 30% of the area is for pig farming, 40% of the area is for chickens. Meanwhile, the level of protein supply of this worm is as high as that of the foods mentioned above. In Vietnam, although mealworms are only raised to serve ornamental birds, other insects such as crickets, ca cuong, chits, bamboo worms, black thorn ants… have been bred or exploited in the wild for trading. sold for human consumption. Other benefits Research results from Stanford University have informed the miraculous ability of mealworms. That is, they can eat foam plastics and other forms of polystyrene. There are some insects capable of degrading plastic such as the wax worm Achroia grisella and Galleria mellonella or the Mediterranean moth (Plodia interpuncella)… that can chew, eat and digest plastic as garbage bags. In the intestines of mealworms, there are many species of microorganisms capable of degrading polyethylene (PE). 100 mealworms are capable of consuming 34 – 39 milligrams of foam insulation, equivalent to the weight of a capsule per day. Larvae that eat all foam insulation are just as healthy as those that eat bran. The mealworm converts plastic into CO2, biomass and waste that can be broken down by bacteria. This waste appears to be safe to use as fertilizer for plants. They have designed a breeding area for mealworms with three purposes: Decompose plastic, provide food for people and use waste to make fertilizer for plants. The breeding area for powdered worms is made from organic glass (plexiglass) and is designed to be divided into 4 floors. The adults (male and female) will be kept on the top floor. Their eggs, when laid, will fall through small holes to the second floor. Here, the eggs will hatch into larvae and be fed sponge. As the mealworms grow, they are moved to the third lower floor. Here they are fed powder to cleanse their intestines and pupate. The mealworm droppings on the third floor will fall on the fourth floor and be collected to be used as fertilizer. At the third floor, we can collect the mealworms for food or let them grow into adults and then bring them back to the top first floor to continue the breeding cycle. Farms that raise mealyworm larvae can produce more edible protein than traditional farms that raise chickens, cows, pigs or dairy cows for the same amount of land used. The researchers compared the environmental impacts of a mealworm farm with that of traditional livestock farms using three parameters. These are land use, energy demand and greenhouse gas emissions. They found that for each unit of edible protein produced, worm farms required much less land and energy.

When they love each other, even though they live in two places, they always have fun conversations about what they want to do in the future. Especially both love nature, want to do something on the countryside land. The couple came together from a love of gardening. “I started to get inspired about gardening, growing plants, producing food after going to the farmers market in the city every week,” Lauren shared. She then learned about the benefits of growing her own plants, cooking broths from fresh produce, and baking. After marrying Tyler, the two together continued to study nutrition and transmit useful gardening information to many people. Returning to the town is not as vibrant as in the city, the couple feels like they are enjoying the life that is exactly what they both wanted for a long time. Tyler shared that the two chose to live on the east coast of Australia, with more than 4 hectares of land for farming. In addition to planting trees, the couple is also interested in improving the natural ecosystem, avoiding harm or killing beneficial insects. One of the natural ways to prevent plant pests is to keep ducks and chickens around the garden. In addition, they also raise a few sheep. The couple said: “We live in the tropics so high temperatures, strong winds, drought, some other natural disasters are challenges with gardening. But we believe that whatever you plant, If you put your heart and effort into nurturing them, they will pay off, so happy to see them grow day by day.” Lauren and Tyler not only grow crops to provide food for their families, but also store seeds to share with many people, inspiring those who love to create clean food for their families with their own hands and aim for a better life. sustainable living. “We’re not inheriting land from our ancestors, we’re borrowing land from future generations,” says Lauren. “This reminds us not to focus entirely on immediate needs, but instead take responsibility. responsibility, a sense of how current actions will affect the world our children live in. I hope everyone has positive thoughts and intentional actions to live a life of purpose and connection with together”. Hoang Dung ( translation summary)

I have a chance to chat with Prof. Dr. Bui Cong Hien , former lecturer of Biology Department, University of Natural Sciences, VNU, leading entomologist in Vietnam about 10 years ago. At that time, he was retired and was dreaming with his friends to open a gallery of paintings made from insects. At the age of 80, Prof. Dr. Bui Cong Hien is still working hard. After a few years, I had the opportunity again follow GS.TS. Bui Cong Hien visit the artificial butterfly farming model in Ba Vi (Hanoi) made by himself. During those meetings, he told me about the insect world, about the benefits of insects and his predestined relationship with insects. He said, when he was still a student, he studied at the Department of Physics, Hanoi University (now Hanoi National University). He said that at that time his knowledge of insects was very little. Most of the time the teacher assigns a topic to do it. he did “Study on the phototropism of insects”, “Biology and ecology of the rice weevil (Sitophilus oryzae)” all suggested by the instructors. “Later, when I was retained as a teaching staff, I was assigned to the insect group of the Department of Invertebrates, Department of Biology. When going to work as a PhD student in the GDR, following the advice of Prof. Dao Van Tien, I chose the direction of research on Insect Physiology, a very bony research direction. Maybe I have a predestined relationship with insects, so insects chose me,” he wittily shared. He said, from that fate, he focused on researching insects in many directions such as insect pests, applied entomology, pheromones of insects, insects in Vietnam and prevention of harmful insects. , insect resources in Vietnam and valuable insects… From these studies, the benefits of insects he called “gold mines”. He affirmed that with more than 1 million species and living in all habitats, there is no creature that is attached to humans, being both “enemies” and “friends” like insects. Although small, the insect world is both “romantic” and “realistic”. Insects can kill people, but they also create jobs that feed millions. He asked the question: if insects were not present on the planet, how would humans live when the earth was filled with dead animals and plants; when the fruit is not pollinated… Sad because Vietnam is wasting gold mines Prof. Dr. Bui Cong Hien said, when studying insects, he discovered that many people call insects “insects” implying that insects are harmful species. Insects are “guilty” to humans. But that makes up less than 1% of the more than 1 million species. In fact, we are “a worm that upsets the whole pot of insect soup”. Prof. Dr. Bui Cong Hien said, we don’t know how to mine gold from insects. He said that insects bring 10 benefits to nature and 15 benefits to humans such as making food, beautifying, improving soil, pollinating plants… Especially Vietnam is a country with high biodiversity, with a large number of insects. However, we do not yet know how to mine gold from insects. Currently, according to GS.TS. Bui Cong Hien, in our country, the conservation and exploitation of insects, especially those in the wild, are rarely studied. “I had the opportunity to go through the market in Dien Bien, and saw the sale of worms and bees… I feel so sorry. Because people spontaneously exploiting insects have been both “victims” of poverty and backwardness, and “criminals” of biodiversity destruction”, he confided. “Why not research and help them breed these objects into farms to harvest and process valuable products like some countries have done. Why in many countries there are companies trading insects, but in Vietnam, they only sell at the market like hundreds of years ago. Earlier this year, the EU allowed the farming of mealworms (Tenebrio molitor) as food for humans, while in Vietnam only selling mealworms for ornamental birds,” he added. Plans at the age of 80 Currently, Prof. Dr. Bui Cong Hien has turned 80. However, he still cherishes many plans. The gallery made from insects in the past could not open for many reasons, but now he is still determined to do it. Nutritious nuggets from insects that he used to make successfully in the past, with recipes and designs available, he did not want to give up halfway. “I raised the issue with the Department of Culture, Tourism and Sports and the Bac Ninh Museum. In my opinion, besides traditional Dong Ho paintings, there should be Dong Ho paintings from butterfly wings to enrich folk paintings. Now I’m waiting for funding,” he revealed. The famous entomologist also said: Currently, he has researched and completed the process and technology of insect breeding, and the technology of making nutritious nuggets from insects. What he wishes is that there are businesses and entrepreneurs who realize the value of supporting insects, or invest in building a project to breed and exploit a few specific insect species. He said he is willing to transfer the technology. Invite readers to watch the video: Dangers of using weight loss foods online. Source: VTV24.

But few people know that inside the factory campus is also home to 600,000 bees. And every day, the bees are still rushing around in search of honey, living at the same pace as the production of supercars equipped with powerful V12 engines. Are the bees living in the Lamborghini factory responsible for helping the engineers here research to design models that inherit the aerodynamics from animals and insects as often seen in the history of the automotive industry? paint the world? A worker wearing protective gear with the Lamborghini logo checks honey at the beekeeping area in the factory Reality is not like that. On the occasion of May 20 every year chosen by FAO as World Honeybee Day, Lamborghini supercar company is also pleased to announce the latest count results of the population of bees in its factory which has reached 600,000. Back in 2016, the Italian supercar maker kicked off a biomonitoring project with the construction of eight beekeepers in the Lamborghini park at the Sant ‘Agata Bolognese factory. To date, the number of beekeepers has increased to 12 and it has an important task in understanding how the environment surrounding the plant affects the habitat of humans as well as insects. And bees, with their random behavior of pollinating in the process of collecting honey, will give quite accurate results on environmental quality. At certain times, entomologists associated with the Lamborghini factory will test the quality of honey and wax to assess environmental quality. Currently, the green trend in the auto industry is almost the target of many famous car manufacturers. Not only planting more trees, expanding static space, but some factories like Ford also increase waste water reuse or produce car accessories from recycled materials. As for beekeeping to assess the quality of the factory environment like Lamborghini, Bentley has recently learned and launched a similar project last year.

Balut Illustration. This dish is very popular in Southeast Asian countries such as Vietnam, the Philippines, Cambodia, and Laos. In which, the duck eggs are incubated for 16 to 20 days, then boiled and eaten with sliced ​​fresh vegetables and ginger. Most foreigners will not dare to eat duck eggs because it feels like a scary dish. Durian Despite its very eye-catching colors, this famous fruit of these Asian countries is not popular with Western tourists. For many people, the smell of durian is quite unpleasant, so they have to cover their noses a hundred meters away. Even some tourists cannot eat this fruit even a piece. Rotten tofu Considered a dish of the Chinese in the past. Stinky tofu tastes like rotten feces, but to the person who eats them, it tastes delicious, extremely ecstatic. This dish is usually deep fried, served with sauerkraut and soy sauce. For Western guests, trying tofu is definitely a difficult and unforgettable challenge. Tuna eyes This is one of the most exotic Japanese specialties. Tuna eyes are very hard, only the cone-like jelly can be eaten after steaming. This dish makes many Europeans dare not look, let alone eat. Shirako (fish genitals) Shirako is made with sperm sacs from fish. According to many people, shirako is not easy to eat. Its taste has a strong smell but the Japanese love to eat fresh shirako. Bat soup Although bats are also often eaten by many Asian countries, seeing black bats in a bowl of specialty Indonesian soup still makes many people feel scared. Natto Natto is a type of fermented soybean with a very unpleasant smell and sharp taste. On the surface of natto covered with viscous, silk like spider webs. Most people can’t eat natto because they can’t stand the smell of it, not because it doesn’t taste good. Raw horse meat Basashi – raw horse meat is a traditional Japanese dish. The meat is thinly sliced, easy to put in the mouth, served with grated ginger and some herbs, dipped with shoyu soy sauce. Although many people commented that the taste is not bad, for Western tourists, eating red meat is still a big challenge for them. Insect In many Asian countries such as Thailand, Cambodia… insects are an indispensable part of culinary culture. Here, insects such as spiders, scorpions, locusts… are often piled high and ready to be used as snacks. Many people who eat insects will find the food very delicious and nutritious. However, for many people, trying dishes made with insects still requires a lot of courage. Fresh octopus This is a famous Korean dish. The tentacles of the octopus are chopped and eaten as soon as they are grabbed on the plate, or if you are braver, you can eat the whole one. However, eating the whole octopus is quite dangerous because the suckers on the tentacles can stick very tightly and cause suffocation.

Aphids is a type of beetle, most commonly found in Bay Nui, in two districts of Tinh Bien, Tri Ton (An Giang) and the southwestern border region. Aphids reproduce in large numbers at the beginning of the rainy season and last for about a month. This time is usually from April to May of the lunar calendar, depending on whether the year rains sooner or later. In the past, leafhoppers were considered harmful insects for farmers because they often bite young shoots, especially in mango, mulberry, and cashew trees… But recently, people in the border areas have discovered it. how to fry aphids, turn this insect a delicious and nutritious dish. Since then, many people have sought to hunt to process aphids into a unique delicacy, notably the deep-fried mealybugs. The beetle has a beetle-like shape, the size of a thumb, brown cockroach wings, short body, wings, very hard head and legs, but soft and round body. The sage beetle is dry, does not bite like some other insects. The people of this country consider this a “unique” dish, only eating for 1-2 months a year. Therefore, new beetles become a specialty. The way to catch leafhoppers during the day is to pick up cow dung, dry buffalo dung and burn it for smoke to rise to the sky. After a while, the beetles smelled the smell and just flew away, dancing in the smoke. People kept holding brooms to beat the bugs to the ground and then put them in baskets. Hunting beetles at night is simpler and more gentle. The catcher just needs to hang a bright lantern right under the mango tree, where there are beetles gathering on the tree. Just a few minutes later, the light-loving beetles were flying and falling on the ground. The Bay Nui leafhopper is larger than a thumb with a characteristic shape of the beetle, so it looks “difficult to swallow”. However, when they have passed through the hands of the housewives in the mountains, they seem to have completely molted. In the past, beetles were considered the food of the poor. But today, this insect has become a specialty, becoming a favorite dish not to be missed in restaurants and pubs. Just like how to process rice crickets, nymphs or scorpions, hoppers only need to be cleaned by removing wings, legs and gutting, then rinsing with warm water mixed with salt. Then, the cook marinated the beetles with sugar, MSG, pepper, and garlic for about 20 minutes, then caught the pan to fry until crispy. The food stalls and restaurants will have a beautiful presentation, while the dishes of the people in the countryside are simple and rudimentary, but the taste is also crispy, fragrant, fatty, and not inferior. People who know how to make aphids when removing their intestines will not squeeze all their eggs, because the eggs are very delicious and fatty, once eaten, they will remember forever. Crispy fried beetle can be served with raw vegetables, tomatoes, cucumbers and salt and pepper with lemon. Just like eating fried scorpions, people who eat aphids for the first time often feel scared because the animal is ugly and the color is not fresh and attractive. The eater just needs to put it in his mouth to bite, the taste will immediately spread, the fat of the meat penetrates into each tooth root, not mixed with any other flavor. Photo: IT.

Along Highway 14 to the inter-commune roads of Hon Quan district (Binh Phuoc) these days, we can easily see cashew orchards, mango, bare leaves because of beetles (people also call are beetles) harmful. Locals said, beetles appeared here nearly ten years. However, the previous years were not significant. Close-up of a beetle that damages plants in Binh Phuoc. Photo: TT. This year, for some reason they appear quite dense. Currently, people are very worried because the leaves of the plants have been eaten up, resulting in loss of photosynthesis, the plants are depleted, output has decreased, or even died, while not knowing how to effectively prevent and treat. Recognizing the fact that at some mango orchards in Dong No commune (Hon Quan district), drizzling weather for many days is a favorable environment for beetles to multiply and develop. In some orchards, there has been a phenomenon of beetles biting leaves, limb branches, and even many gardens leaving only young fruit hanging. Growers have bought pesticides to spray but have not been able to prevent the onslaught of beetles. Ms. Pham Thi Huyen Trang in Dong Tan hamlet, Dong No commune has 7 hectares of mangoes at harvest age, but in the past few days, beetles have caused nearly one third of the mango area to be destroyed and there is no sign. stop. With the method of spinning the lights, every day she catches tens of thousands of children. However, this method does not appear to be effective due to the large number of bugs. “Now the beetle has eaten all the young leaves of the mango tree. If not, in a few weeks, all the leaves of the mango tree will be eaten up. With this situation, mango trees will inevitably be depleted, the next year’s crop will decrease yield “, Ms. Trang worried. Similarly, nearly 1 hectare of mango and cashew of Nguyen Huu Cong’s family nearby were also gnawed clean by beetles. Mr. Cong said that when he discovered beetles, his family bought pesticides to spray, but only a few days later they reappeared. Many orchards were bitten by beetles, leaving only their branches. Photo: TT. “After more than a month of being eaten all the leaves, the trees are sprouting again, but the spreading bugs continue to attack. With this situation, surely the trees will be depleted, the next season’s yield will drop sharply, some trees. We hope the authorities will consider the reality and take measures to support farmers to prevent this insect “, Mr. Nguyen Huu Cong suggested. Not only harming plants, beetles also upset the daily life of people. Beetles are mainly active at night, only need to see the light that they come in, making people here not eat and sleep. Many households, in order to limit bugs from entering the house, people have to close their doors and turn on the power in the yard and then “entrench” in the house. Mrs. Ho Thi Dai from Hamlet 3, Dong No Commune, Hon Quan District shouted to heaven: “My house is next to the cashew garden, so it was affected a lot. Although the house was closed at night, beetles still entered through the places. When they fall onto the floor, bugs release a red substance that looks like thin blood. At night they crash into the roof of the roof, making a noise that causes sleeplessness. Need a radical solution Concerning this issue, Mr. Tran Hai Ha, Head of Department of Agriculture and Rural Development of Hon Quan district, said that the unit has grasped that beetles attack and damage plants in the area. “There are many communes in the district that are attacked by this beetle. We are giving statisticians the area and extent of the damage of the households,” said Mr. Ha. Not only cashew trees, many mango orchards were also attacked by beetles, leaving only the fruit and branches. Photo: TT. According to Mr. Ha, 2 weeks ago, the district Department of Agriculture and Rural Development worked with the District Agricultural Service Center to give directions to deal with this problem. Mr. Ha said that these bugs are difficult to destroy, not as easy to spray as common insects. Currently, the Department of Agriculture and Rural Development is waiting for the Center to come up with solutions to help people prevent this species of bugs. Regarding measures to control this beetle, Dr. Nguyen Van Bac, working at the Bu Dop District Agricultural Extension Center (Binh Phuoc), said: In the world there are 200 types of beetles, rarely seen for leaf-eating beetles. described in national documents. Most likely, this beetle belongs to the type of beetle that eats leaves of mango (Chafer beetles), scientifically known as Apogonia sp, belongs to the family Scarabaeidae, order Coleoptera. Harm mainly on trees of industrial trees and fruit trees such as palm, coconut, cashew, mango … According to documents, leaf-eating beetle eggs are laid in blocks, near the base, consisting of many eggs, each egg is wrapped in a hard layer of soil. Eggs are 1.0 – 1.3 mm long, white, bulging and round later. The incubation period is about 9 days. The newly hatched larvae are about 3 mm long and reach 15 mm before pupating about 10-11 weeks later. Lungs live in the soil, eating the roots of a variety of crops, weeds and decomposing organic matter. The larval stage is about 72 days long; pupae 2 – 3 days; pupae: 7 – 10 days; life cycle is about 3 months. At first time the city is brown, then it turns black. A beetle destroys things. Photo: TT. In the Southeast in general, Binh Phuoc in particular, bugs often outbreak and cause damage at the beginning of the rainy season (April – May). After dancing, bugs eat leaves, young branches of wild plants and plants. They mainly feed at night, and during the day they live hidden under the topsoil. For prevention and treatment, Dr. Nguyen Van Bac recommends that there are 3 methods: manual measures, which can use light traps at the same time in areas where many harmful beetles appear. Chemical measures, using active insecticides Permethrin, profennophos to spray in the evening. Biological measures, using bacillus thuringiensiss (Tricho-BT), Metarhizium anisopliae (green fungus) to spray on plants and in the soil to kill eggs and young offspring before becoming larvae. Currently, beetles continue to cause harm on many cultivated areas in Hon Quan district and are at risk of spreading to a large extent in neighboring areas. The most effective is the light trap The Department of Plant Protection said: Through working with the Agricultural Service Center of Binh Phuoc Province and the Agricultural Service Center of Hon Quan District (Binh Phuoc), it was known that this beetle appeared in recent years, usually arising from the beginning of the rainy season (April), extending to the middle or the end of May will decrease (actually, by May 10, 2021, it has decreased compared to the previous month). Many farmers in Binh Phuoc worry because beetles continue to damage crops and upset their daily lives. Photo: TT. Adult beetles are nocturnal, eat all kinds of leaves (cashew, mango, rubber …) and have a strong tendency to light. Therefore, the safest and most effective measure at present is to use light traps (high capacity will attract more power), underneath put a water basin with a layer of active petroleum scum, and beetles plunge into the falling lights. water pots, oil scum will seal the breathing holes on the two sides of the beetle stomach, causing rapid death. On May 10, 2021, the Plant Protection Department sent a mission led by Mr. Do Van Van, Director of the Southern Regional Plant Protection Center (under the Department of Plant Protection) to Binh Phuoc to understand the situation, take samples of beetles and send them. appraise to know scientific names, from which to grasp habits, biological characteristics, host plants to determine the most suitable and effective control measures. The Department of Plant Protection also confirmed that this beetle has appeared in Vietnam for a long time, not the main pest on crops in Vietnam. In recent times, a number of new species have arisen, such as the “black bean” beetle, the coffee beetle in Kon Tum, and the forest leaf-eating worm in the city. Ho Chi Minh City, Binh Duong, Dong Nai … They are pests on forest trees, but when their numbers break out, they spread to harm crops or affect people’s lives, but not harm (such as “black beans”). Also according to the Department of Plant Protection, in 2018, a similar species of beetle also appeared harmful to coffee young leaves during the basic construction phase in Dac Ma commune, Dac Ha district, Kon Tum province, but with a smaller size. The result of identification is species Maladera castanea, family Scarabaeidae, order Coleoptera. The Central Center for Plant Protection (under the Department of Plant Protection) has cooperated with Kon Tum Plantation and Plant Protection Department to guide farmers to apply the method of attracting light traps to kill beetles and protect coffee trees in recent years. ..

Over the past 10 years, many conservation initiatives and solutions have contributed to effectively protecting the biodiversity common home. (Photo: Hung Vo / Vietnam +) After more than 6 months of launching, the program “Honoring organizations and individuals with many contributions to the conservation of wild species in the period 2010-2020” by Ministry of Natural Resources and Environment The launch is coming to the last stage. It is expected that the ceremony to honor individuals and organizations participating in the program will be held on May 21, 2021, in response to the Day Biodiversity international (May 22). Thousands of species are named According to the representative of Department of Nature Conservation and Biodiversity (Vietnam Environment Administration, Ministry of Natural Resources and Environment), in the past decade, Vietnam has witnessed many changes in economic, social and conservation life. biodiversity is no exception. Although operating in silence, scientists and conservation organizations have contributed to creating a brilliant decade of biodiversity with a series of research, new species discovery and initiatives and solutions. effective conservation. Especially, right after launching the above honoring program in October 2020, the program has received many records from individuals and organizations working in the field of species conservation. Many animal and plant species have been studied and discovered for the first time for science and published in prestigious international journals. Among thousands of species of animals and plants recognized and recognized internationally, many species of insects, reptiles, amphibians … are classified as critically endangered, and should be prioritized for conservation; Many studies have found endemic species only in Vietnam. Some newly discovered species include scorpion Euscorpiopsis cavernicola (in Ba Be district, Bac Kan province) and scorpion Vietbocap thienduongensis (Phong Nha-Ke Bang National Park, Quang Binh province). In addition, precious tree species such as Moc Huong (Aristolochia), genus Arachniodes, … have also been studied on phylogenetic and evolutionary relationships for practical application. Through research, many valuable plant species in medicine and production are identified and have reasonable conservation plans. Many outstanding landmarks in conservation Along with species discovery research, the program honors organizations and individuals with many contributions to the work wildlife conservation the 2010-2020 period also recognizes many initiatives and solutions, contributing to improving the efficiency of efforts of all levels, sectors and the society in species conservation. The precious otter who was illegally confined and sold at the farm product disguised as Thanh Hoa, Long An province, was rescued by the competent forces after receiving a report from the reporter of VietnamPlus. (Photo: Hung Vo / Vietnam +) The first solution mentioned by the Department of Nature Conservation and Biodiversity is the successful breeding and conservation of white-crowned Lei Lamas – a rare and endemic bird of Vietnam. In addition, the pairing and spawning of the White-bellied Cao Sand Bird has also been successful, serving environmental education and conservation in the future. Besides breeding solutions for endangered species, other initiatives also focus on wildlife rescue. Among them, there are groups of volunteers who have rescued 100 sea turtles, of which 94 are still alive and have been returned to the sea; or process of rescuing bears, raising bears in semi-wild environments … In particular, the program received a story from someone who used to be a hunter but now leads a voluntary group to conserve white-nosed langurs in Quang Binh. Thereby, it contributes to preventing the impact of the quarrying program, protecting the habitat for langurs. As a result, in 2018, the People’s Committee of Quang Binh province has partially planned the forest into a special-use forest to balance conservation and exploitation needs. In addition, some units also made a mark with the initiative of using camera traps to investigate wild species in some key areas or the application of technologies in monitoring and re-release. wild animals and preserve the gifts given to Vietnam by the Creator. Assessing the significance of the program, professor-doctor of science Dang Huy Huynh, ASEAN Biodiversity Hero, Vice Chairman of the Vietnam Association for the Protection of Nature and the Environment said that this is a conservation initiative. of great significance, helping to motivate and encourage the development of the scientific research movement on biodiversity. During the working process, the review board found that the submitted documents were in compliance with the rules, some documents were carefully prepared, showing the enthusiasm for the program. The dossiers are evaluated on the basis of selection criteria in the issued rules./.

Elephants in the Central Highlands. (Photo source: PV / Vietnam +) According to the General Department of Environment (Ministry of Natural Resources and Environment), the subject of International Day of Biodiversity (22/5) in 2021 was chosen by the Secretariat of the Convention on Biological Diversity “We are part of the solution.” The theme was chosen to continue the cross-cutting theme of 2020 “Our solutions are available in nature” as a reminder that biodiversity remains an important solution, an option for Sustainable Development . From nature-based solutions to climate issues, health, food security, drinking water and sustainable livelihoods, biodiversity is the foundation on which we can rebuild for the better. Due to the complicated ongoing COVID-19 epidemic around the world, the 2021 International Day of Biodiversity will be commemorated through an online campaign. In a new study published in the Journal of Frontiers in Forest and Global Change (excluding Antarctica), scientists identified only 3% of the world’s land is still ecologically intact, with healthy primitive populations and undisturbed habitat. This number is only for the nature of “approximate estimate.” The study used range maps of 7,000 word species Red List of the International Union for Conservation of Nature. Most of the data is from mammals but also includes some birds, fish, plants, reptiles and amphibians. The world is in a biodiversity crisis, many wildlife populations, from lions to insects, are plunging in numbers, mainly due to habitat loss. Some scientists believe that the 6th mass extinction on Earth is beginning and will have serious consequences for food, clean water and air. Vietnam is one of the most important and biodiversity countries in the world, both in terms of marine and terrestrial ecosystems (especially forest and mangrove ecosystems). According to the Vietnam UNESCO Office, 238 priority ecological zones have been recognized around the world, of which 6 are located in Vietnam. Several nature reserves in Vietnam are recognized by UNESCO for their unique universal natural value, including 3 natural heritages, two global geopark, 9 biosphere reserves and two Wetlands are located in two world biosphere reserves. However, Vietnam’s conservation efforts are facing various difficulties and challenges such as: biodiversity degradation trends have become more important due to deforestation and illegal logging. legal, overexploitation, economic growth and population pressure, have enormous impacts on the key services these ecosystems provide. According to the Department Nature conservation and biodiversity (Vietnam Environment Administration), nature-based solutions is a term that can be used to describe alternative and non-traditional approaches to environmental problems such as flooding, water scarcity or soil erosion, by exploiting natural capital. Can Gio mangrove forest. (Photo: Manh Linh / VNA) Solutions could include restoring and conserving coral reefs and mangrove belts to increase resilience to coastal flooding and sea level rise, serving as the first line of defense for dissipation. energy waves and vegetation to reduce the risk of landslides and create green belts to help replenish groundwater in areas facing water scarcity. In response to the International Day of Biodiversity on May 22, 2021, the Ministry of Natural Resources and Environment will honor organizations and individuals who have made many contributions to wildlife conservation in the 2010-2020 period. According to the General Department of Environment (Ministry of Natural Resources and Environment), the Selection Council is composed of managers from the Ministry of Science and Technology, the Ministry of Agriculture and Rural Development, the Ministry of Natural Resources and Environment, and other Leading scientists in the field of species conservation such as Professor, Doctor of Science Dang Huy Huynh – Biodiversity Hero of ASEAN. The dossiers to participate in the program honoring organizations and individuals with many contributions to the conservation of wild species are evaluated on the basis of the selected selection criteria. Each profile is consulted by all experts in the council, ensuring transparency and fairness. According to the Selection Council, the discovery of new species, initiatives and solutions for biodiversity conservation is of an important nature. Documents participating in this program show that there are thousands of named wild flora and fauna species, many of which are endemic to Vietnam. Many initiatives and solutions contribute to improving the efficiency of efforts of all levels, sectors and the society in species conservation. Initiatives on reproduction, breeding and successful conservation of rare species, care solutions, propaganda and especially initiatives from volunteer groups to protect species life and inspire those who has been and wants to contribute to this field. Scientists believe that the first time the Ministry of Natural Resources and Environment has an initiative to organize a program to encourage and encourage the development of the scientific research movement on biodiversity is a meaningful activity taking place. In the context of increasing climate change, the rate of biodiversity degradation of our country and the world tends to increase. It is expected that the Ceremony to honor individuals and organizations participating in the program will be held on May 21, 2021./.

In recent days, Mr. Nguyen Dinh Long in Thach That, Hanoi often sells on facebook some batches of ca cuong at an expensive price: 35,000 VND / head. On the surface, Ca cuong is no different from cockroaches, but they are sold at such a high price that startles many people. However, Mr. Long commented, the selling price of Ca cuong this year has decreased significantly compared to last year due to the Covid-19 translation. In previous years, the retail price of Ca cuong never fell below 5 million VND / kg and below 50,000 VND / unit. Ca cuong looks like a cockroach He shared that he imported Ca cuong from Laos or some areas in the South; After that, bring them to Hanoi to sell to retail customers or restaurants selling snacks. In the North, there are very few Ca cuong because people abuse plant protection drugs in the field, so Ca cuong almost rarely appears. Explaining why this thin-bodied insect resembling cockroaches and stink bugs is bought by many people, Mr. Long said: “Ca cuong lives both on the banks and ponds, under water rice fields, but carries essential oils. rare. Therefore, many customers who buy Ca cuong will wash them and then put them on the grill. Then, they cut into small pieces and put directly into the sauce or use gradually “. Or for more convenience, many customers buy Ca cuong to extract the essential oil and store it in a sealed jar. Each time they eat, they just need to bring 1-2 drops into the bowl of sauce. Due to the expensive price of Ca cuong, most retail customers only buy a few to a dozen. Particularly for the rich, the house with conditions or the restaurant or restaurant has just ordered 0.5kg to 1kg. This man added, 1kg Ca cuong usually consists of 80-100 children, depending on the big or small. Calculated, 1kg Ca cuong costs about 3.5 million. One day, Mr. Long sells at least a few dozen to 200 ca cuong. But inside the body they contain special essential oils Many customers like Ca cuong, imported goods go anywhere “On Tet holidays, Ca cuong is asked by many customers to soak fish sauce, use essential oils to spice up festival dishes such as rolls, bun cha, vermicelli … Roasting coffee stalks as bait. However, due to the scarcity of goods, our house is not much for sale. Customers who want to pick up must book at least a week to return the goods ”. In addition to selling whole fresh Ca cuong, Mr. Long also imported a few other products extracted from Ca cuong at a price that is not cheap, such as: Whole Ca cuong fish sauce (soaked 10 males) 500,000 VND / bottle Ca cuong essential oil 300,000 VND / bottle, Ca cuong wine 1.2 million / 2 liter bottle. As a construction engineer, Mr. Tran Van Kien in Cau Dien, Hanoi has just ordered 0.5 kg of male Ca cuong to soak in wine and soak fish sauce. Although their prices are expensive, he is very fond of this insect. “Male Ca cuong has an essential oil smell like cinnamon. When taking the essential oils out, my wife often let her husband soak fish sauce or wine. Eating at the dipping country house always has a familiar tomato cuong taste. Because the tomato sauce has the slight scent of cinnamon and banana oil, now without the tomato cuong, the sauce is very bland, “Kien said. Mr. Kien said that his family has Ca cuong essential oil to eat almost all year round. Therefore, when friends come to his house to eat and drink, the bowl of tomato sauce and tomato wine has an unusual smell, complimenting him because this is a unique and strange dish that few people know.

Indian dance ants. The new owner of the throne has the ability to expand the ovaries, reducing the size of the brain to take over the responsibility of reproduction for the whole herd. The battle for the throne Ants have a relatively simple “class” distribution system. While the queen is responsible for laying eggs, the rest of the herd must find food, feed the ants, join the battle, and build nests. Only male ants and queens are capable of reproduction, and other ants cannot. If the queen dies, the whole herd must suffer the same fate. Similarly, the Indian dance ants (Harpegnathos Saltator scientific name) include queens, reproductive males and a group of worker ants who are females. Queen ants hold the highest position in the ant colony, living 5 times longer. Only it is allowed to give birth. In most species of ants, the queen is born, not chosen from a herd. However, the Indian jumping ants allow worker ants to compete for a chance to sit on the throne, becoming a queen ant. Research published in the scientific journal Proceedings of the Royal Society B: Biological Sciences in early April showed that, in this species, if the queen died, about 70% of the female ants in the herd would compete for the throne. . The fight lasted for about 40 days. The opponents used the beard to fight until the competing group had 5 – 10 remaining. These animals continue to spend the next days to reproduce because the ovaries are enlarged while the brain shrinks up to 25%. After the war, the winning child will expand her fertility like a queen and become the second queen. The others return to being a worker, so the ovaries shrink and the brain enlarges again. Professor Clint Penick, the lead author of the study, commented: “This is an unprecedented miracle in the insect world. The toughness of this species allows them to swap roles in the herd. Professor Penick has spent many years studying the Indian dance ants. When worker ants become queen ants, they are called “gamergates”. All worker ants in the herd are capable of reproduction, but they are only allowed to do so when they win the throne. In the natural world, many species of insects, like bees, also compete for dominance. But the jumping ants fight to give birth, which really impressed the scientific experts. When a gamergate becomes a queen, its body goes through a complex transformation process. The queen will stop producing the venom, change its behavior like evading intruders, not hunting. Notably, their brains shrank by 25%, while the ovaries were enlarged by 5%. Indian dance ants can shrink the brain, enlarge the ovaries. Looking for a solution To analyze the queen ant transformation, Penick and his team selected 60 gamergates, painted them to distinguish them, then quarantined them for several weeks. When isolated, gamergate decreased fertility. But when they returned to the herd, they were captured and imprisoned by the worker ants. Penick explains that the gamergates are being controlled by the whole herd. The worker ants stopped the other ants from reproducing because this behavior was beyond the queens of the queen ants. If it was discovered that a member with the same function as the queen ant, the worker ants would bite and detain it for many days even though it did not endanger its life. Scientists hypothesize that this behavior causes a series of internal changes to the gamergates, making them likely to become queen ants but also as worker ants. The transformation happens in a few days. The reason the Indian jumping ant’s brain can shrink is because the gamergate does not have to use the brain to forage, protect the nest from predators. Their main job is to reproduce, while worker ants need large brains to think about these problems. Another reason gamergate shrinks the brain is to conserve energy. This behavior has also been observed in the Etruscan shrew, a small mammal. Their brains shrink in the winter to limit energy, helping to keep other parts of the body warm. Some other animals also have the ability to change brain size such as ground squirrels, birds. White-crested sparrows, for example, create 68,000 new nerve cells during the breeding season to help them recognize mating calls. In winter, when food is scarce, some of the nerve cells die on their own, and in the spring, they revive again. But this phenomenon is rare in insects such as ants. While Rachelle Adams, a researcher in ant evolution and ecology at Ohio State University, thinks maybe this behavior is not as special as we think it is. The problem is that scientists have not fully understood and discovered about the Indian hopping ants may be the foundation for further research in this field. As brain modification is studied more and can be found in many different species, it will have special significance in understanding the human brain. For example, research into the brains of the Indian gerbil helps to understand more about genetic control, the ability of genes to control flexibility in animals and towards humans.

The lizard has the ability to run on the super ‘top’ water The Central American lizard spends most of its time in trees or shrubs watching small insects or vertebrates pass close enough to grab it. But when it is threatened, it can plunge into the water and escape. The reason is that lizards have the ability to walk on water thanks to their skillful “rowing” rear legs with the support of a long tail. This talent for walking on water like doing a circus earned it the nickname “the lizard of Jesus.” Not only that, it is also capable of running on water at speeds of more than 11km / h and diving under water for 30 minutes. Hound’s sense of smell Under the sleeping hound’s sleepy eyes was his super sharp nose. This nose is 1 million times more audible than a human nose. That is why the police used to hunt for missing people or fugitives. A hound’s nose has more than 200 million olfactory cells, so it can store the odor and follow it for days despite the presence of other odors on its way to its target. Thanks to this super-sensitive sense of smell, the hounds become famous “experts” in solving cases in the world. The eagle’s eyesight All birds of prey have sharp eyes. And this is a powerful “weapon” to find food. But eagles have special eyesight above all else. According to calculations by scientists, eagles can see target details at least 8 times better than the most pure human eye. This is due to the fact that the sunshade in each eye blocks sunlight and has a high concentration of cone cells in the vision. As a result, it positioned its prey with incredible accuracy. The eagle can see a hare several kilometers away. That is why they are symbols of sharp eyesight. Find your way in the moonlight of the beetle Scientists have observed that beetles routinely move the dung ball that is many times larger than its body by “planting a banana tree” and using its hind legs to push the ball away. But further research they discovered that this insect also possesses a talent that has never been known in the animal kingdom: navigating paths by moonlight. It can move in a straight line despite obstacles they may encounter along the way. The beetle’s competition for food (other animal droppings) is fierce, so as soon as a colony forms a dung ball, it tries to hide this dung ball to do ” dry wages ”later. The fastest way to escape from another stumbler is the straight path. The miracle is that this species can trace a straight path just thanks to the moonlight. It seems that the insect relied on a pattern created when moonlight interacts with molecules in the air (polarization) to move in a straight line. On days without moonlight, beetles tend to change directions, take a detour to keep them safe and have less trouble. The lion dance Thanks to its incredible power and speed, the leopard leopard is one of the most terrible predators on the planet. But the lion’s leopard high jump and long jump skills are admirable. His muscular hind legs and large claws are designed for a powerful jump. The lion leopard can jump up to 15 meters (50 feet) away and jump up to 6.6 meters, which is quite a big difference compared to humans. It is the advantage of this long jump and high jump skill that makes it easy to catch up with prey even after a long distance. Navigating with the sound of the bat Bats are animals that possess many unique things and have very interesting adaptations. Many species of bats often turn upside down to sleep and live on the blood of other animals. They are also the only flying mammals. But the most impressive feature of the bat is its ability to hunt with echolocation. Accordingly, the bats send high-frequency clicks as they fly, then they hear the oscillation from the echoes bounce back and that indicates the prey position is not far away. With this system, they can catch and eat about 1000 insects per night. The ability of sharks to receive electricity Sharks are one of the most successfully evolved animals on earth. Thanks to the diversity of adaptations, sharks have many advantages in the wild. One of these adaptations is the ability to receive electromagnetic waves, making the electrical impulses in the shark’s body extremely sharp. As the prey swims, this movement sends tiny electromagnetic signals through the water. Sharks receive these signals as the water travels through the jelly-filled pores of the head. Connected to the internal compost, signal reception allows the sharks to find prey quickly and they can kill the prey with great precision even in cloudy water. This hearing organ also makes it possible for sharks to detect the smell of prey blood, even a drop, from miles away. Swimming speed of squid and octopus Squid and octopus are the fastest invertebrates in the ocean. This is in part due to the body’s extraordinary ability to use jet boosts. When water flows into their outer cavity, it is held under pressure and the mouth closes. As the muscles of the wall contract and press, pressurize the full water back through the cartridge and allow it to run at a speed of 40 km / h. These cephalopods can also control the direction and speed of movement, allowing them to escape from a threat or to quickly advance to prey they want. The magic wings of hummingbirds Not only are the hummingbirds one of the most beautiful birds on earth, hummingbirds are also the most impressive flying birds. The joints between the upper and lower wings are located very close to the body so they are agile and have a surprisingly leveraging effect in the air. Hummingbirds flap their wings at a frightening speed-80 times per second. They are also the only birds capable of flying forwards, backwards, upwards and downwards. Hummingbirds can float in the air, which makes it easier for them to absorb nectar while in flight. The running speed of the leopard At a speed of 110 km / h, the leopard is the fastest running animal on the planet. This is thanks to the long limbs, small head, and slim body, the spines will curl and stretch with each stride, helping to push the body forward faster. Thanks to this movement that it has increased speed more than 30 km / h. But the surprising thing is that this species can not speed fast for more than 10-15 seconds, longer it will cause their body to overheat. This is also understandable because leopards mainly live in deserts and steppes where there is very little chance of hiding in the shade.

A colony of giant grasshoppers is a terrible disaster. They begin with a black streak on the horizon, followed by darkening gradually. The small rustling noises gradually turned into the shrill noise of the millions of yellow insects that came. Since the end of 2019, grasshopper clouds have spread across the Horn of Africa, devastating crops and meadows, prompting people to trigger a massive campaign to destroy them. The ground and air spraying of insecticides in eight East African countries, coordinated by the World Food and Agriculture Organization (FAO), prevented the worst scenario – the destruction of the grasshoppers. the food source of millions of people. In 2020, according to FAO calculations, the campaign will preserve the amount of grassland and food enough for 28 million people in the Horn of Africa and Yemen in a year. But this progress has come with unspecified consequences for the environment, and the difficult problem is to find a way to destroy this invasive insect without destroying plants, harming insects, and wild animals. wild and human. The consequences have not been determined To date, 2.3 million liters of chemical pesticides have been sprayed on 1.9 million hectares, at a cost of about $ 195 million (according to FAO statistics). This campaign will continue this year. Assessment of damage to the environment is not complete, but the effects of the insecticide have been recorded for centuries in other areas. Extensive pesticides not only kill grasshoppers, but also bees and other insects. They penetrate into water sources and can affect human health. Dino Martins, executive director of the Mpala Research Center in Kenya, said: “Of course there will be uncontrolled damage. All these chemicals are made to kill insects, and they do it with that. bulk”. Grasshoppers formed in 2018, after a hurricane brought heavy rains to the Arabian desert, allowing them to breed on wet sand. Strong winds in 2019 push the flock to Yemen, then across the Red Sea into Somalia, Ethiopia and Kenya. Grasshoppers proliferate quickly and eat everything in the way they fly. Photo: National Geographic. The spraying was carried out even when the Covid-19 pandemic spread around the world. Wearing masks, hundreds of local volunteers and Kenyan conscripts wore aerosols and sprayed the grasshoppers with any pesticide in stock. They sprayed tens of thousands of liters of deltamethrin, as well as hundreds of liters of fipronil, chlorpyrifos, and other insecticides. In particular, many types are banned in Europe and some parts of America. In the reported case in the northern Samburu region, a ground control team sprayed 35 times the recommended amount of chemicals on an area, killing both bees and beetles. “Originally, this was an emergency situation. The idea was to try to control as quickly as possible to control the environment,” said Thecla Mutia, head of the environmental impact monitoring group of locust control efforts in Kenya. ensure food security “. Struggled to find an alternative Pesticides are poisons. Four types used in Kenya under FAO censorship have a high risk of harming bees, low to moderate to birds, medium to high with grasshoppers and soil insects, such as ants and termites. The European Union has banned the use of chlorpyrifos since early 2020, and some American states such as New York, California, and Hawaii also banned it. Fenitrothion is not approved for use in Europe, but is used in the US and Australia against grasshoppers. “We are not hiding the nature of the insecticide, but we cannot do anything while the grasshoppers spread. We want to reduce the number of desert locusts,” said Cyril Ferrand, FAO’s team leader in Nairobi. in a responsible way. Grasshoppers wreak havoc on crops with terrifying speed and scale. Photo: BBC. Biological solutions that are non-toxic, which can kill grasshoppers without harming other species, have been around for decades. However, chemical pesticides remain the top choice, accounting for up to 90% of the solution sprayed during the campaign in East Africa. The development of biological insecticides began in the late 1980s, after the grasshopper epidemic lasted for many years, stretching from North Africa to India. Christiaan Kooyman, a Dutch scientist who makes a bio-insecticide from the fungus Metarhizium acridum, which attacks grasshoppers, said: “When we see the number of millions of liters of pesticides sprayed, even the community. Donating them was also frightened. And they asked, ‘What else can I do?’ Metarhizium, marketed since 1998, has been proposed by FAO as “the most suitable control solution” for grasshoppers, but is rarely used. The drug works slowly, giving it a low “suppression” rate – that is, killing after days instead of hours. At the same time, its use was very expensive and difficult, more effective with young than adult swarms of grasshoppers – which was a great threat at the time. The biggest advantage of Metarhizium – just killing grasshoppers – also makes it a less profitable product. Companies make very little money making the drug, and go through the costly licensing process in one country and take a long time until it is allowed to be used. “Grasshoppers don’t usually show up, and businesses aren’t interested in producing something that isn’t used,” said Graham Matthews, a scientist on the Pesticide Review Foundation founding council. The grasshoppers come, you don’t want to wait for new production, you want a solution. As a result, governments have used wide-ranging, readily available chemical pesticides. Pesticides are the solution of choice to control grasshoppers. Photo: FAO. What worries the farmers, herders, scientists and conservationists of Kenya with these chemicals is that there is so much unknown – if any – about the harm they cause. A US government assessment warns “the risk of a significant negative impact on the environment and human health”, and the World Bank considers that the risk to the environment is “enormous”. “The use of large amounts of pesticides will of course harm biodiversity, but the magnitude of the effects has not been determined,” said Sunday Ekesi, an entomologist who joined his own anti-desert locust force. Nairobi, said. A major concern in Kenya is the impact of pesticides on pollinators. Farmers believe that the disappearance of bees is a factor in the low production of honey and mango. However, the lack of surveillance information makes it difficult for scientists to know what is actually going on. FAO’s 2003 guidance on safety measures shows that aerial spraying has no less impact on human health than ground spray, but often presents “more environmental concern” because There is a risk of entering sensitive areas in the ecosystem. In general, Kenya’s current grasshopper eradication campaign has improved compared to the first few weeks. If done correctly, the environmental impact will be very low. However, not many official reports have been published on this matter. Aircraft sprayed insecticides in the area invaded by locusts. Photo: FAO. Raphael Wahome, an animal scientist at Nairobi University, said FAO needs to release reports soon, so that researchers can evaluate more comprehensively. “Our main concern is that it’s all focused on locust control without the parallel monitoring system for undesirable effects,” he said. occurred where the “pesticide was used”.

Living in a riverside village in Van Giang district (Hung Yen), Ms. Nguyen Thi Thuy said, the pretend is a specialty only available in the Red River. Their larvae live in water, only surface once a year to molt and then fly to the surface to lay eggs. Close-up of the child pretending to be outside the Red River. (Photo: Van Thanh). According to Ms. Thuy, when she was a child, many children appeared pretending to be, but suddenly about 20 years they disappeared, causing nostalgia for generations of fishing villages. However, about 3 years ago, pretending to appear many times made the people of the fishing village excited to come out and get together to go out and pretend from 3am. “I pretend to only appear once a year around February to March of the lunar calendar and only live about 2 hours. To get rid of it, most of my family had to stay up all night to see if the next day’s situation would pretend or not. If there is, by about 4 am, the pretense will start to float, and the river will be completely flown by about 6am, ”Ms. Thuy said. The child pretends to be a specialty only available in the Red River, which can be purchased at quite high prices. On the day of pretending to appear, dozens of fishing boats with nets attached to the nose of the boat ran along the river. When it is clear, it is also the end of the fake harvest. Because people were brought up from the riverbank, people gathered and bought them all. At the beginning of the crop, the price was high, about 500,000 VND / kg, every day when it was picked up, it was about 300,000 VND / kg. “On average, my family can salvage about 3-5 kg ​​a day, but there is a record day that my house can salvage nearly 40 kg. Bring it to the market, have not yet sold out all. Because it only appears a few days / month, it is necessary to be able to watch it to avoid the end of the season ”, Ms. Thuy said. Nearly 20 years of “losing track”, about 3 years ago, the pretend started to appear again. As the owner of a famous restaurant in Ngoc Thuy, Long Bien (Hanoi), but Van Thanh still goes out and pretends because this is an insect that has attached to the childhood of riverside children like him. At the same time, he used pretend to cook into dishes to serve guests to eat at his restaurant. In order to catch the pretense, fishermen like Thanh had to prepare from 3am, use a fixed net at the nose of the boat and pick them up because they only appeared from 4-6am and disappeared. According to Thanh, there are not every place where there are pretensions, but only at the confluence of the river where there is a lot of soil for them to nest. “Usually it takes a lot of attention to be able to watch the right day of pretending to molt because only 1-2 times a month. After 2 molting, they lay eggs and then die. Eggs hatch into larvae and return to the river bed waiting for the day to be molested on the surface “, Mr. Thanh said. After being processed, the baby becomes a specialty, with the price up to a million VND / kg. After picking up, Mr. Thanh processed many dishes to serve diners such as pretending to braise fish, pretend soup, pretending to roast honey leaves, and pretending to fry eggs … If he can save a lot, he proceeds to preserve it. separate to be used all year. “From the beginning of the crop up to now I have picked up 2 times, each time about 10-20kg. If selling fresh, it is only about 500,000 VND / kg but processed, each kilo can make 4 plates with the price from 200-300,000 VND / plate. So, each kilo of pretense will cost about 1 million dong ”, Mr. Thanh shared. I pretended to be a phytoplankton, after molting, only lived a few hours on the water. According to the book “Ten thousand questions of why”, I pretend to belong to the set of Ephemeral Wings, a set belonging to a group of Palaeoptera, together with the order of Dragonflies, whose scientific name is Ephemeroptera. They are twofold. After the second time, they only have one pair of wings and then live for only a few hours. The longest lifespan of pretending is not more than a week. The larvae of the child pretend to live in the water, after rolling a few times to become the same. When it becomes a coincidence, its body is soft, light emitting, the two antennae on the head are like a dagger, at the end of the abdomen grows 3 tail feathers. In the evening the children pretend to gather, fly over the water to perform mating. After the sex is finished, pretend the female spawns the eggs in the water. The vast majority of them to the next day “deadlock”.

One case of a patient with hand, foot and mouth disease must be hospitalized for treatment. According to the health report in April 2021, just sent by the Ministry of Health to the Office of the Government, in April, the country recorded 64 cases of viral encephalitis, including 1 death in Ben province. Bamboo. It is also the first case of death from viral encephalitis this year. Cumulative since the beginning of the year, the country has recorded 145 cases of viral encephalitis, equivalent to the same period in 2020. In addition, this month also recorded 2 cases of meningitis due to meningococcal tissue but no death case. Cumulative since the beginning of the year, the country has recorded 8 cases of meningitis caused by meningococcal tissue (an increase of 4 cases compared to the same period last year), of which 1 case died in Ho Chi Minh City. Also in this month, the country recorded 3,728 cases of dengue fever, 2 fatalities. Accumulating from the beginning of the year up to now, the country has recorded 19,710 cases of dengue fever, 5 deaths in Binh Duong (1); Phu Yen (2); Soc Trang (1), HCMC (1). Compared to the same period in 2020, the number of cases has decreased by 16.3%, but deaths increased by 1 case. In addition, hand, foot and mouth disease in the country this month recorded 8,705 cases and 3 deaths. Cumulative from the beginning of the year until now, the whole country has recorded 20,756 cases of hand, foot and mouth disease, 4 deaths in Dak Lak (1); Kien Giang (2); An Giang (1). Compared to the same period in 2020, the number of cases of hand, foot and mouth disease nationwide has increased by 1.9 times. With suspected measles fever, the whole country also recorded 69 cases, of which 17 cases were positive, there was no death. Accumulated from the beginning of this year, the country has recorded 173 cases of suspected measles fever, of which 21 cases were positive, and no deaths were recorded. Compared to the same period in 2020, the number of cases decreases by 12.8%, the number of positive cases decreases 156 cases. According to the Ministry of Health, Vietnam is a tropical country, circulating many infectious diseases transmitted by insects, including viral encephalitis, especially in the summer, the season suitable for insect transmission. Viral encephalitis is a dangerous condition caused by a variety of viruses, often causing damage to the brain, resulting in neurological sequelae and high mortality. In order to proactively prevent and fight epidemics in the summer of 2021, the Ministry of Health has sent an official letter to the Department of Health of the provinces and cities to strengthen surveillance, early detection, isolation and thorough treatment of outbreaks. at the same time take samples for testing to determine the causative agent. In particular, the provinces / cities must step up the expanded vaccination, ensuring the rate of over 95% of the commune, ward and town scale and organize the campaign of environmental sanitation, mosquito elimination, and larvae. .

With the 10 mosquito repellant tips below, you will easily take advantage of natural ingredients to create substances that protect yourself from these insects without the use of chemical repellents. Natural plants You can grow a number of useful mosquito repellants like horsetail grass, basil, rosemary, garlic, kale, lavender, lemongrass or marigold. This way, the clean garden and the plants above also effectively protect you and your pets from mosquitoes. If you live in an apartment, you can grow them in foam boxes or in small, pretty pots. Body spray and lavender oil Mosquitoes hate the smell of lavender. You can use this essential oil as a body spray or as a lotion to your skin. This is not only a healthy mosquito repellent tip, but also helps keep your skin from getting irritated and allergic. Lemongrass candles Tips to repel mosquitoes with lemongrass candles. If you do not have a garden to plant trees or you are allergic to the above plants, lemongrass candles are a great solution to repel mosquitoes. Lemongrass is a popular natural insect repellent recognized by scientists. It doesn’t have any side effects and keeps your home fresh. If you like handmade things, you can make homemade citronella candles with essential oils. Apple cider vinegar Apple cider vinegar has more benefits than you might think and most people have a little at home. If your residence is suddenly attacked by mosquitoes, make your own vinegar repellent. You can also add a little lemon lemongrass essential oil for the added effect. Spray this mixture in places where insects often gather and see effect. Soapy water If you spend a lot of time sitting in the courtyard for family dinner or relaxing, place a dish with soapy water nearby. After a while, you will find that mosquitoes are attracted to soapy water and are stuck there, unable to disturb you. Garlic According to some studies, eating garlic helps to repel mosquitoes. But if you don’t like to eat garlic then just boil the garlic water and spray the mixture in places where mosquitoes gather. Essential oils, cloves, basil, eucalyptus Using aromatherapy is one of the most effective mosquito repellent tips. The essential oils of these four plants can effectively repel mosquitoes. Dilute them with water (5-10 drops per glass of water) and apply to exposed skin or spray them on heat sources such as heaters, scented lamps, and hot pans. You can also dip a cotton pad in the essential oil and place it on a window sill. Vanilla powder Mix vanilla powder with baby lotion at a ratio of 1:10 and apply on all exposed skin. You can also dissolve vanilla in water, then spray the mixture on exposed skin and clothing to combat mosquitoes. Basil leaves You can use basil leaves and flowers, or chopped cherry blossoms. Place them in the room or rub them on exposed areas of the body. This is a very effective mosquito repellent tip. Cooking oil, shampoo and vinegar Tips to repel mosquitoes with a mixture of cooking oil, shampoo and vinegar. To make an effective mosquito repellent, you need some cooking oil, shampoo and 9% vinegar. Mix these ingredients in equal quantities and stir thoroughly until white foam appears. Pour mixture into container and leave it open. The vinegar repels insects, the shampoo hides a strong odor, and this blend is safe for children, nor does it cause a strong odor.

Vegetables should be soaked in running water several times before processing Asparagus. In asparagus also contains a special enzyme, which helps it remove the pesticides that humans spray on. This is the reason that almost asparagus contains very few harmful chemicals, even 100% clean. Peas. One of the strong points of peas is its thick outer shell. They not only protect the beans from the air, but also prevent pesticides from entering. You just need to peel off beans to be eaten immediately, not soaking too thoroughly like other foods. Papaya. Like peas, papaya’s thick skin will prevent chemicals and pesticides from entering and causing harm. Not to mention this fruit is also easy to grow, easy to bear fruit, so many places do not spray. Corn (corn). The thick crust protects the corn from environmental influences, including pesticides and harmful chemicals. Avocado. Avocados have a fairly thick shell, and the pesticides left on the shell are removed during processing before being consumed. Pineapple. In a test of 360 pineapples, up to 90% contained no residues of pesticides. This is partly due to the fact that pineapples have a rather thick shell that acts as a natural protective barrier. Tubers. Sweet potatoes, carrots, onions, beets, .. contain very low levels of pesticides compared to other foods because they grow deep in the ground, pesticides are difficult to penetrate into tubers because covered by soil. These tubers are less susceptible to pests and have a long storage time, reducing the amount of pesticides. Gourd, squash, melon, eggplant. With vines, the content of pesticides on the fruit is very little, so it is considered one of the safe foods for health. Gourd, squash, and melon have a thick shell, minimizing the penetration of the drug inside. Types of herbs, natural flowers. These are quite safe vegetables because insects are rarely eaten, so they do not have to use pesticides as much as other vegetables such as vegetables or cowpeas. In particular, herbs are fragrant vegetables, this is also a natural insect repellent. These vegetables can be grown naturally without the need for pesticides. Jute, spinach, amaranth. Because they are insectivorous vegetables that are rarely eaten, they themselves are less likely to use pesticides compared to many other vegetables. Kiwi. Most people usually remove the skin of kiwi when eaten, but in fact they are completely edible, in addition to providing an abundant amount of fiber for the body. Cantaloupe. Because cantaloupe usually has a rather thick peel, it forms a protective film against pesticides. The skin of the melon is like a net, along with the low acidity content creates a favorable environment for bacteria. Broccoli. Broccoli is less susceptible to pests and diseases because they can secrete a plant compound that helps fight harmful insects. Mushrooms. Fungi have almost no residues of pesticides. Many people use mushrooms instead of meat, which is both safe and also provides a large amount of nutrients. Sweet potatoes. This is an easy vegetable to grow. Just plug the stem in the moist soil and the plant can thrive. It also does not take much effort to take care of the sweet vegetables, and there are few pests, so growers do not need to spray pesticides.

Chinese paleontologists have found ancient insects, snakes, ancient birds and even dinosaur tails in fossil Burmese amber. Thanks to the special preservative properties of amber, these fossils have retained their original shape after 100 million years. One of the dinosaur feathers discovered in the amber piece was damaged by chewing and the markings are similar to the feathers of modern birds with parasitic lice. Feather is one of the types of “special impurities” preserved in Burmese amber, including neck feathers and insect feathers. Not long ago, two pieces of feathered amber from Myanmar attracted paleontologists because through microscopic observations, the researchers noticed some ancient bugs in the feathers. Although these bugs are small and hard to see, paleontologists have found that they have unique and striking habits. The newly discovered insect is named Mesophthirus engeli, revealing the early makeup of the lice ancestor. Mesophthirus engeli has no wings and a body similar to a lice. The team found that they chewed very vigorously through the marks of a dinosaur’s fur. A team of researchers from the Capital Education University of China, the Chinese Academy of Sciences, the Capital Medical Science University, the National Museum of Natural History, and the Russian Academy of Sciences studied the studies. Small insects preserved in amber and discovered this particular beetle. Archaeologists have named this tiny insect Mesophthirus engeli with the genus “Mesophthirus” from the Greek word and the name “engeli” is dedicated to Michael S. Engel, a famous paleontologist. Americans, in recognition of his outstanding contributions to the study of ancient insects. The earliest appearing fur-eating insect was thought to be Megamenopon rasnitsyni. The lice fossils were unearthed in Germany 44 million years ago, according to Chungkun Shih, study author at the Smithsonian Institution’s Museum of Natural History. Researchers also found evidence of Jurassic and Cretaceous parasitic parasites 66 to 201 million years ago. This ancient bug was very small with a length of less than 0.2 mm, so researchers had to use an electron microscope to see its shape. Mesophthirus engeli looks very much like today’s lice, but it has a larger head with black dot-like eyes on the sides and two tentacles with three long spines on top of the head. Mesophthirus engeli can be said to possess a body “three rings as one”, with the head, chest and abdomen equally wide, six feet short, with claws and long spines at the end, can be grasped. This finding suggests that the insect’s feathering behavior has originated at least in the mid Cretaceous period. Although it looks like a lice, the Mesophthirus engeli species is far different from modern lice and lice. Hence, paleontologists established a new ancient taxon of insects – Mesophagous caterpillars. Compared with the body, the mouth of Mesophthirus engeli is very large and strong, two large jaws are serrated, capable of chewing very strongly. In addition, the researchers also found that in the amber pieces containing these ancient bugs all had the presence of feathers and they all existed signs of damage: broken niches formed near the body. feathers and feathers are also broken. The marks of damaged feathers resemble those left by a feather-eating bug after chewing on the feathers. And obviously, the culprit of these traces was none other than the Mesophthirus engeli species. The origin and early evolution of the hairy trait in insects is inherently ambiguous due to the lack of records of Mesozoic fossils – the period of tectonic, climatic and progressive activities. chemical. Blood-sucking insects were found during the Jurassic and Cretaceous periods, but dinosaur fur-eating insects have not been previously reported. The discovery of this ancient feather-eating beetle is of great significance, because it has pushed the history of feather-eating insects to 55 million years, because before the discovery of this beetle, the earliest feather-eating insect. is known to mankind in the Kainozoic era 44 million years ago. Thus, the discovery of Mesophthirus engeli filled the gap in the early evolution of a feather-eating insect. Mesophthirus engeli lived in the Cretaceous period 100 million years ago, this is also an important period of diversity and differentiation of primitive birds and feathered dinosaurs, it can be said that this is also the setting stage. parasitic relationship between feathering insects and their host.

All objects falling into the air have terminal velocities depending on their size, shape and mass. The terminal velocity of an ant (6.4 km / h, according to the physics department of the University of Illinois) will be much different from the human terminal velocity (about 200 km / h). “For rats and any small animal, there’s really nothing dangerous. You can drop a mouse into a mine nearly 1,000 meters deep and when it hits the bottom, it gets dizzy and runs away. , provided that the ground is quite soft The air resistance acting on the moving object is proportional to the surface of the object.If the length, width and height of an animal are divided by 10, then the mass. Its amount is reduced by 1000 times while the surface area is reduced by only 100 times, so the air resistance for small animals is usually 10 times higher than the actuation force. Force is usually not an issue for insects, it can fall freely without danger, with the ability to cling. ” Michael Kaspari is an ecologist at the University of Oklahoma (USA), who has studied the aerial activities of wingless ants. Research shows that when ants are confronted with a predator, they jump in the air from tall branches and use their legs to steer their flight to the tree. The longer hind legs will allow the ant to travel through the air, preventing it from falling into places they deem dangerous. With this ability, it is possible that the ant has managed to cling to something before it falls to the ground, and whether it can grip or not, the ant will not die if it lands. The most ancient creatures still exist today It is thought that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to biota, it is estimated that ants make up about 15-20% of the total number of terrestrial animals. Ants are animals belonging to the membrane wing, the layer of insects. Scientist Corrie Moreau and his French colleagues published a study that found ants appeared 140 to 170 million years ago. That means they are the most ancient creatures that still exist today, despite the intense fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survival is bestowed on nature, since they show no signs of consistent change. Which means it is very likely that an ant 170 million years ago and an ant now are no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are found all over the earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the colors are usually just red or black. Especially, there is a species with white color added. Ants live in herds, with a quite separate social organization. Each nest has an average of about 100,000 children in a herd with a single mother (God ants, can live up to 30 years). Here, there is something like the way bees organize the swarms of life. The great majority of baby ants in the herd are worker ants (who only live 1-2 years) – such as the hardest and most hardworking workers on earth. The job of worker ants is to take care of queens, incubate eggs, transfer eggs, raise young ants, build caves, forage, guard … Few people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become God prejudices, but are forever just “cu-li” legs from birth. to death. Ants are considered the most powerful because they can carry food 10 times heavier than them. But to transport that heavy food, they have to use collective strength in coordination. Together, they carry the food they can find easily, when thousands of them work together. Ants are everywhere, anyone can see them or be stung by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as tools for wound healing. When one of the tribe was injured, they would capture a few large ones from the “army ant” group so that they would bite on either side of the wound, then remove the body, leaving only the ants on the wound. From there, the wound did not bleed and healed quickly. And interesting things about ants Ants are animals with a fairly sanitary life. Specifically the handling of the dead. When one is dead, the other ants in the herd together carry the dead ants out of the nest, with the sole purpose of keeping clean, avoiding infection or disease spreading. Worker ants will take care of carrying under the command of an ant that is believed to be responsible for the funeral of the flock. It was also surprising that ants were insects with a very advanced organizational system. Along with God ants, worker ants, and the commanding ants of burial, there are also “teacher” ants. Born, to have the necessary skills, they go through a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In the event that “students” learn slowly and “fail” on a test, they will be transferred to another job that requires less skills. Not only know how to find termites, but also know “breeding” to create a food reserve. They know how to feed insects such as aphids and moths to get the sweetness they produce. When it is time to harvest the sweeteners from the insect swarm, the ants “milk” using their antennae. It is extremely interesting to know that ant colonies carry a swarm of insects that they cultivate when moving to a new area. It is no different than humans taking cattle along to places where the grass is lush. People have talked about extraordinary in the ant world. They do not have ears but senses sounds from ground vibrations through the sensitive sensors on their legs. They have the ability to survive miraculously despite the extreme weather and climate. That is why ants are also one of the first organisms on earth to be sent to space by humans in experiments to conquer the sky. Ants have poor eyesight, in return they often use the earth’s magnetic field to guide their way. They are considered the smartest insects when there are more than 250,000 brain cells in the small head of ants. As a hard-working animal, ants are also said to be “great athletes”. If an ant was about the size of a human, then it could run at an average running speed of 55 km / h without ever getting tired. They can once again lift an object 50 times its weight with incredible strength.

Mosquitoes transmit diseases such as chikungunya, dengue fever and zika. (Source: wwmedgroup) These mosquito carriers, species rodent animals Destroying crops, wood boring insects, and even domestic cats are invasive species that are causing enormous harm to humans and the natural environment. According to a study published March 31 in the journal Nature, researchers working at the Laboratory of Ecology, Taxonomy and Evolution at the University of Paris-Sacla in France estimate invasive species. the so-called damaging alien species has cost the global economy nearly $ 1,300 since 1970, averaging $ 26.8 billion a year. The actual number could be even higher, researchers warn. The team synthesized a wide range of harms that invasive species cause to different habitats, including plants, insects, reptiles, birds, fish, mollusks, microorganisms or animals. mammal. Most harm is related to ecosystems, crops, fisheries and disease control measures. The team has made a preliminary list of the top 10 invasive pests, including the plant-eating rats and the Asian gypsy moth – two species that are devastating crops across the Northern Hemisphere. The list also includes zebra mosquitoes native to Southeast Asia that transmit diseases such as chikungunya, dengue fever and Zika. According to the researchers, the average annual damage caused by invasive species triples every decade. However, there is some evidence that the number of invasive species has increased “exponentially” due to increasing international trade, as humans import many species of organisms. In Australia, wild rabbit populations of European origin, first recorded in the early 19th century, have become invasive species causing great harm to the ecology of the Oceania nation. this over the past 150 years. They reproduce at an uncontrollable rate, consume soil, damage native species, as well as destroy crops with billions of dollars in damage. On the island of Guam, US overseas territories in the Pacific, invasive brown tree snakes native to Australia and Indonesia have “slaughtered” the majority of native bird and lizard populations since being accidentally brought in to come here in the mid-20th century. They also threaten people and sneak into equipment, causing frequent power outages. In forests in the US and more recently Europe, the longhorn beetle originating from Asia is also destroying the vegetation, causing serious damage to the ecosystem. According to the study, domestic cats are also among the top 10 invasive pests. This animal that has been “traveling” around the world for hundreds of years has now become an “invasive” species on most islands in the world, “slaughtering” birds, reptiles and animals. Amphibians in many parts of the world. The United Nations Scientific Advisory Committee on Biodiversity (IPBES) said that it is among the top 5 culprits of environmental destruction worldwide, along with changes in land use and resource exploitation. , pollution and climate change. In 2019, IPBES estimates that the number of invasive species has increased to 70% since 1970 in the 21 countries studied. Laboratory director on Franck Courchamp said international trade will increase more species of organisms introduced, while climate change will help more of these imported species survive and thrive. With the above research, scientists hope that by giving a figure of the damage caused by invasive species, people as well as authorities will raise awareness about the severity. of invasive species. Early detection, good data combined with preventive measures can significantly reduce the damage invasive species cause. The researchers also hope this issue will be included in the list of the serious environmental challenges facing humanity to receive more attention.

Japanese people flock to the viewing spots for flowers. Photo: Getty. Each year, cherry blossoms only reach “peak in full bloom” for a few days. This is the law of nature that has existed for more than a thousand years. When it comes to cherry blossom season, Japanese people often flock to flower viewing spots for picnics or commemorative photos. But this year, the cherry blossom season comes and goes quickly. Scientists call this the earliest blooming season in history, and point out the cause: a climate crisis is threatening the ecosystem. The flowers bloom early The timing of cherry blossoms in full bloom can vary from year to year, depending on factors such as weather or rainfall. But in general, the cherry blossom season tends to come sooner. Researcher Yasuyuki Aono from Osaka Prefecture University gathered historical data in the city of Kyoto. According to Aono, this year’s flower season in Kyoto starts on March 26, the earliest in more than 1,200 years. Aono expert data shows that the city of Kyoto welcomes the cherry blossom season around mid-April for many centuries. From the 1800s, the flowering season shifts to around early April, during which a few years the flowering season takes place at the end of March. “Sakura flowers are very sensitive to temperature”, Mr. Aono analyzed. “The temperature can determine when the flowers bloom. Compared with the 1820s, the current temperature in Japan has increased by about 3.5 degrees C “. He also said that this year’s flower season clearly reflects the change in temperature. Specifically, this year’s winter in Japan is very cold while spring comes incredibly fast and warm. Therefore, cherry blossoms have “awakened with enough rest”. Cherry blossoms in Washington, USA, also bloom early. Photo: Getty. In Tokyo, the cherry blossoms bloom from March 22, the second earliest time in history. “As global temperatures warm, spring frosts occur early, leading to early blooming of cherry blossoms,” said Dr. Lewis Ziska of Columbia University of Environmental Health Sciences. Not only in Japan, the cherry blossoms in Washington, USA, also bloom early. According to the management of the National Park, this year’s cherry blossom season lasts only nearly a week, from March 31 to April 5. Ecosystem randomization However, early blooming is only the “tip of the iceberg”. Associate Professor Amos Tai from the University of Hong Kong warned of the global climate crisis that could destabilize the ecosystem and threaten the life of all species. In fact, plants and insects depend on each other. Both groups need to interact, influence each other, and at the same time need signals from the environment to “adjust their own life cycle”, according to Mr. Tai. Plants, for example, sense the temperature around them. If the temperature is warm enough for a certain amount of time, they will start to leaf, shoot and flower. Likewise, insects and many other animals are temperature dependent throughout their life cycle. Rising temperatures can accelerate growth in animals. “The relationship between plants and insects and other organisms has evolved over the years, that is, thousands to millions of years,” said Mr. Tai. But in recent centuries, climate change is destroying everything and disturbing these relationships ”. Plants and insects can react to increases in temperature at different rates, leaving their lifecycle out of sync. This means plants and insects may not grow together in the spring. Now, flowers can bloom before the insect is ready, or vice versa. “Insects will not find nutrients from plants and plants do not have enough nutrients to pollinate,” Mr. Tai concluded. In Tokyo, the cherry blossoms bloom from March 22. Photo: Getty. According to a 2009 study in the journal Biological Conservation , over the past few decades, a number of flora and fauna have transformed themselves to escape the effects of climate change. But the ecosystem is increasingly difficult to adapt, as the climate becomes unpredictable. “Ecosystems are not used to such large fluctuations,” said Tai. “The productivity of ecosystems can be degraded, even collapsed in the future.” The effects of climate change are not limited to cherry blossom season. Mr. Tai said that life cycle changes occurred in many crops of economic value, posing challenges to food security and farmers’ livelihoods. At the same time, food supplies in some vulnerable areas are also directly affected by drought and grasshoppers. “Farmers will find it difficult to predict crop yields,” said Mr. Tai. “Farming is now like gambling. Climate change is randomizing every factor in our ecosystems ”.

Follow-up tests showed that the baby had a severe blood clotting disorder, a large decrease in platelets consistent with the initial judgment. Doctors quickly infused 4 bottles of anti-green snake venom serum to the baby and closely monitored clinical signs.

After more than 24 hours of follow-up, C’s hand was not swollen more, no bleeding, but the disorder of blood clotting had not improved, he was given 4 more vials of anti-green snake venom. The results showed that after 6 hours of second serum transfusion, the baby’s hemostasis tests gradually returned to normal, no bleeding on the mucous membranes, and better eating and drinking.

According to the family, the baby woke up and woke up and complained of pain while sleeping. On examination, family members found that the baby had a slight abrasion and swelling in the 2 knuckles of the middle finger of the right hand and thought it was not serious, after 7 hours of home observation, the bite was swollen, spreading the whole hand up to the forearm. being taken to private medical facilities for treatment with only temporary relief of pain and swelling.

On the afternoon of April 9, 2021, when the baby was taken to the hospital, his hand was swollen swollen to the arm area, the middle finger was more painful.

How to recognize and first aid when bitten by insects or snakes:

For Insect bites (bites): Be aware of mild soreness at the site of the bite, the sting, and swelling around the bite. If severe, hives will be generalized, shortness of breath, anaphylaxis, cold hands and feet, mild pulse, difficult to catch, hematuria, low urination, kidney failure usually occurs in the first days.

First aid way:

– Most bee stings leave a sting and bag of venom in the sting on the victim’s skin, except for wasps. It is best to pry the syringe out by gently gently squeezing, using tweezers, avoid squeezing by hand as this can cause the venom to spread.

– Clean the affected area with soap and warm water

Apply a cold compress to the bite to reduce pain and swelling

– Take the victim to a medical facility if: The victim complained of fatigue, cold hands and feet; Red urine, little urine. Was stung on 10 marks by wasp.

For snakebites: Recognize that it is necessary to quickly observe the bite, the following signs indicate that the snake bite was much swollen, much pain at the bite site. The bite has two marks of venom that can be a snake with local signs such as swelling, bruising, necrosis and blistering of the skin filled with fluid; disorders of blood clotting: Hemorrhage of the skin, mucous membranes. For the cobra, there are few signs of systemic dizziness, nausea, shortness of breath, and weakness in limbs.

First aid way: When bitten by a snake, even a snake is identified should be closely monitored as a poisonous snake bite, at least for the first 6 hours. In particular, when bitten by a poisonous snake or suspected of being bitten by a poisonous snake, first aid should be taken immediately and promptly bring the victim to a medical facility.

Give first aid by lying down, place the bitten place lower than the heart to limit venom absorption. Clean the wound with soap and water. Cover the bite with a cool compress to reduce pain and swelling. Quickly take the victim to a medical facility where it can determine the type of snake bite and inject an appropriate anti-venom serum.

Helping plants grow

You can’t drink yogurt, but your plant can! Dilute the yogurt with water and pour it into a flowerpot or garden to give the plant some calcium. Just like us, the calcium in milk will help plants thrive, especially for tomato plants. If your plant is in the garden, the sour smell of the milk will keep the insects away.

Lighten silverware

Dull silver will look new with the help of some fermented milk. If yogurt is not available, a few drops of vinegar can be added to the milk. Then, just soak the silverware in milk for about half an hour to let the stains fade away, then rinse with warm soapy water and wipe with a soft cloth.

Thawing food

Food (meat, fish) kept in the refrigerator for a long time will be frozen and lose its freshness, to overcome this situation you only need to put fresh milk into the food to be thawed, ensuring the food will be thawed. Freezes quickly, effectively deodorizes and enhances food flavor during cooking.

Soothes sunburns and insect bites

If your skin is burning from long sun exposure or itching, or pain from insect bites, try using a small amount of lotion to soothe. Mix one part milk powder with two parts water and add a pinch of salt. Apply this mixture to a sunburn or insect sting. The enzymes in the formula will help neutralize the venom of the insect bite and relieve the pain of a sunburn.

Save the pottery

Your favorite drink cup unfortunately cracked or cracked small cracks, but you could not afford to leave it and do not know how to fix those cracks. Do not worry, fermented expired milk will “save” your cracked cup.

Soak the cup in the pot of expired milk and show signs of precipitation, then put the pot on the stove on low heat for about an hour, then turn off the heat, wait for the milk to cool, then take the cup out. At this time, the glass will “miraculously” return to its original healthy appearance.

Always have a jar of apple cider vinegar soaked in the refrigerator in the summer, when insects are raging and can sting you at any time. This is particularly effective because when soaked in apple cider vinegar, the eggshell begins to decompose, allowing the calcium carbonates in them to react with the vinegar to form calcium acetate. An astringent, like zinc oxide and iron oxide lotions, can help soothe, harden, and protect delicate skin.

However, this mixture only has a shelf life of 1 month.

Nursing seedlings

Containers for eggs after use, do not throw them away, but use to incubate seedlings. This is the perfect place to protect plants from animals and weeds.

Egg box used to store handmade things

Keep small buttons, nuts and scrap paper to place in the boxes of the egg box, so it is very convenient to make your handmade things beside you.

Gardening

Crush the eggshell and mix it into the soil for the plant or flower. The eggshell contains calcium, a mineral that is essential for plant growth.

Hair treatment

Egg shells help sweeten coffee

Using eggshell in coffee sounds strange, but actually this is a pretty good way to sweeten coffee. The alkaline calcium carbonate content in the eggshell can reduce the acidity of the coffee, thus making the coffee less bitter. Furthermore, reducing the acidity in coffee also makes this drink healthier.

You just need to add 5g of crushed or pureed eggshell to the coffee powder you use often and make the coffee as usual.

Clean cooking oil after frying

The cooking oil after frying the food will turn black. You can use a piece of eggshell placed in an oil pan. The eggshell will absorb the carbon particles, making the oil cleaner.

Surely you never expected this special use of onion skin, right? Onion peel contains color molecules, giving you a natural, safe, and non-damaging hair color.

You only need to boil a small handful of onions in the water for about 5 minutes. Cover the pot and wait for the water to cool. Strain and take out the water to wash your hair. Leave for a few minutes and then rinse with clean water. For a good effect, you can do this one more time.

Kill fungi and insects for plants

The scent of the onion peel makes the insects run away. You can use the bark to treat fungus and kill insects in your home garden by mixing 100g of onion skin with 500ml of water in a sealed jar. Leave the jar in a cool place for 7 days and then use.

When using, dilute the onion skin juice with clean water at a ratio of 1:10. Spray the solution evenly over the entire plant to kill fungi and insects.

Onion peels have many unexpected uses that housewives do not know.

Make compost

Like other fruit and vegetable peels, onion skin can also be used as an organic fertilizer for plants. The simplest way to do this is to bury the scallions in the ground so that they decompose naturally.

Used to bake bread

The onion skin functions as a dye. When making bread, you can add a little onion crust. The breads will have a more attractive and glossy yellow color.

Add flavor to soups

For a long time, when you cook soup, you still only use the onion to cook the soup without the peel. It is a waste. The rind, after being washed and added to the soup, can make the dish more delicious and taste sweeter than usual.

Accordingly, in the clip, it can be seen that the shop’s staff scoop each ingredient into a cup very professionally and quickly. Each step seemed to be memorized, so the hand ran quickly. However, what makes many people pay attention is that around this person and the pot of water there are many strange insects.

(Source clip: TikTok @ nvk09101992)

Some viewers of the clip said that it was a fly, specifically Facebook RB expressed: “It feels disgusting to see flies surrounded, like this, it hurts my stomach”.

However, many other netizens immediately protested, saying this was a bee, not a fly or any strange insect. Due to the ingredients of Mot water including herbs such as lemongrass, lemongrass, basil, cinnamon, chrysanthemum, honeysuckle, green tea leaves, dried herb, lotus, jujube …, they have attracted bees fly over.

Besides, many customers have come here to confirm that the shop is very clean and the owner is also careful. In fact, if you look closely at the clip, you can see that even though the glass maker is doing it quickly, he still pays close attention to each stage. When taking the straw, this person does not use the handle directly but uses a tongs to ensure hygiene.

The ingredients of Mau Water are mainly from herbal ingredients.

Furthermore, the type of straw that the restaurant uses is also a bamboo straw, environment-friendly material. This has made many people love the special water that is only available in Hoi An.

It is known that Mot shop owner is Nguyen Huu Xuan. Xuan’s grandfather used to be a medicine man, so he used what he learned from him to cook this sweet and cool water. What makes many people curious is that the name “Mót” does not know where it comes from and what it means. According to Xuan shared in the press, Mót was his childhood name. When he opened the shop, he decided to take the names of his grandparents, his parents still called it for this kind of water.
