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.

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.

Chef Bun Lai prepares to make deep-fried cicada sushi at Fort Totten Park, Washington, USA. Photo: AFP Cooking cicadas is becoming fashionable in the US this summer, when billions of cicadas like Brood X have just emerged from the ground after 17 years of cyclical “hiding”. US authorities have warned curious people to think twice before eating this dish. On Twitter, the US Food and Drug Administration (FDA) warned: “Do not eat cicadas if you are allergic to seafood, because this insect is related to shrimp and shrimp. lobster”. The warning comes as people are sharing millions of recipes for ticks. At a park in Washington, people flocked to catch ticks after tasting deep-fried cicada sushi prepared by the hands of Bun Lai, a chef who supports the sustainable food movement. Cyclically, this year comes a time when billions of ticks have lived underground since 2004, when they were still larvae, swarm to the surface, molt, find a mate, lay eggs and die. The chirping sound of ticks is the male’s way of attracting females. Swarms of these fuzzy-winged red-eyed insects have appeared in US states such as Maryland, Pennsylvania, Virginia, Indiana and Tennessee. This year, the ticks appeared unevenly and later than usual due to cold weather conditions and heavy rain in some places. However, that does not reduce the love of enjoying dishes made from ticks.

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.

Mr. Le Minh Hieu introduced the breeding model of black soldier fly. Mr. Le Minh Hieu said that 3 years ago he went on a business trip to An Giang province and knew about the black soldier fly breeding model. However, the models he visited were all models of dry farming with peat, waste and cow dung. With that way of raising, he saw many inappropriate points. Therefore, when he returned home, he researched and learned more about the characteristics and habitat of the black soldier fly larvae. After a period of research, Mr. Hieu has experimented with black soldier flies in a microbial culture mixture, with the principle of using microorganisms to treat odors, and overcome harmful bacteria to create beneficial bacteria. beneficial environment. Mr. Hieu used probiotics in combination with molasses and clean water and allowed newly hatched black soldier fly larvae to live in this environment. At first, Mr. Hieu had to buy black soldier fly eggs from hatcheries from An Giang province, but now he knows how to breed himself without having to buy outside. Currently, Mr. Hieu’s black soldier fly farm has an area of ​​about 200 m2, with each raising of about 1 gram of eggs, 300 kg of commercial larvae will be produced within 12 days. Mr. Hieu further shared, the life cycle of black soldier flies lasts more than 1 month, starting from eggs, larvae, pupae, and finally molting into black soldier flies. Adults live about 3-5 days, do not eat, live in the shade of trees. Black soldier fly larvae produce a substance that is detrimental to the laying and hatching of flies and other insects, making them an environmentally beneficial livestock and a very good food for humans. livestock and poultry. Nutritional composition in black soldier fly larvae before pupal stage is 43 – 51% protein, 15 – 18% fat, 2.8 – 6.2% calcium, 1 – 1.2% phosphorus, enough nutrients Nutrient for animal feed such as pigs, chickens, ducks…, and is the best live food for raising ducks, chickens, fish, shrimps, crabs… Fly larvae can be concentrated, dried and mixed with other substances. other nutrients as feed to completely replace fishmeal in the production of animal and aqua feeds. Mr. Le Minh Hieu uses commercial black soldier fly larvae as chicken feed to replace feed from industrial bran. Currently, with a culture of 300 kg of black soldier fly larvae / 12 days, with a mixture of hydrolysis of black soldier fly larvae, fish hydrolysis plus bean residue and micro-organisms, Mr. Hieu can completely replace the feed. industrial feed for 1,400 ducks, 400 chickens and hundreds of fish of all kinds being raised on the family farm. With this mix of feed, Mr. Hieu calculated less than 3,000 VND/kg of feed, over 50% cheaper than the current cost of 1 kg of industrial bran. Mr. Hieu compares, with about 1,000 ducks raised commercially, with the current price of industrial bran, farmers spend about 80 million dong of industrial bran for ducks from raising to slaughter. As for this method of raising from hydrolyzed black soldier fly larvae, it only costs about 35 million VND in food costs. “With this method of feeding from black soldier fly larvae, animals grow very quickly due to the high nutritional content of the feed, and the risk of disease is also significantly reduced. Therefore, it is very cost-effective in raising livestock and improving the quality of livestock”, Mr. Hieu added. According to the Agricultural Extension Center of Ba Ria-Vung Tau province, the use of insects in livestock production is very popular in the world. Black soldier flies are recognized by the Food and Agriculture Organization of the United Nations as the preferred insect species for waste treatment and use of protein content as an alternative to food for some livestock. Mr. Hieu’s model of raising black soldier flies is a relatively new and very successful model in Ba Ria-Vung Tau province.

Accordingly, in recent days, netizens have been “wake up” by a story related to a piece of beef in a restaurant in Hanoi. A customer while enjoying beef noodle soup accidentally discovered a strange yellow-green spot, which looks similar to a fluke larva. The image of a piece of beef is controversial on social networks in recent days Bringing this problem to ask the shop owner, this young man received an answer that surprised many people. The text of this post is as follows: “I ate a bucket and saw it like this. I really don’t know if it’s normal so I want to ask everyone. Because I’ve never seen this before. At that time, the owner said it was the firmware, this is normal. I hope anyone who understands this can give me more information. If there is a problem with this piece of meat, I will ask the ward to check food hygiene and safety with my witness.” Post by a guest Immediately after being posted, this post received a lot of attention from the online community. Most users think that, looking at such a clear piece of beef, there must be a problem. Others speculated that it was most likely tapeworm larvae. “If you look so horrible, how dare you eat it?”. – “Oh it looks so dirty, how can you leave it like this and sell it to diners, you don’t want to eat it at first glance, like fluke larvae”. – “Obviously there must be a problem, seeing with the naked eye or someone who doesn’t have much cooking experience like me knows it, it’s just that the owner doesn’t want to say it.” – “Hey, I think it’s not a cow’s bucket but it looks more like the shoulder, where they often inject drugs, most likely the meat you see is an abscess, a lot of pus and defects.” It is not clear what the problem is, but the above post is still receiving a lot of attention from the online community and shows no sign of cooling down.

Christian Sommer is an extremely hardworking student, so even while on vacation with his girlfriend, this guy doesn’t neglect his studies. For his studies, he dived into the azure waters under the cliffs of Portofino to learn about the marine life here and found a small jellyfish – Turritopsis nutricula (lighthouse jellyfish). This jellyfish is only four to five mm in size, the whole body is transparent, in the middle of their body is a red digestive system like a lamp, so it is called a lighthouse jellyfish. Although lighthouse jellyfish have a very beautiful appearance, due to their small size, people often do not see or notice them. Immediately after observing and discovering, Sommer collected them in a thin mesh bag and placed them in a container of seawater in the hope of bringing them to the refrigerator and turning them into specimens. But that day was a weekend, on the beach there were many interesting games and because of a bit of playing, Christian Sommer forgot to put them in the refrigerator as originally planned. It was not until the next day that Christian Sommer remembered what he had forgotten. When he found the barrel, he took it out to look, but when he looked closely many times, Sommer found nothing inside the net bag but sea water. So what happened? Even though lighthouse jellyfish are so small they can still be seen with the naked eye, why do they completely disappear in just one? Still not believing his eyes, Sommer checked the container a few more times, this time even more surprised, at the bottom of the container there were many tiny things, almost invisible. can see. After many observations and analysis, Sommer realized that these were exactly the polyps of lighthouse jellyfish. Why did Sommer feel so surprised? In fact, lighthouse jellyfish are a species of hydrophyte, and they have two different developmental stages in their life cycle: a polyp (hydroid) stage and a jellyfish development stage. Adult jellyfish will lay eggs and are fertilized in water, after which they retain the fertilized eggs in the female jellyfish until they develop into planula larvae. These planula larvae can swim freely like worms or float under the sea and then sink to the sea floor to form digestive systems and reproduce asexually into polyps; After asexual reproduction is budding, the polyps slowly develop into adult jellyfish and begin a new life cycle. Usually a jellyfish life cycle lasts a few weeks to several months, and they die after laying eggs. But now, the fact that these jellyfish lay eggs, fertilize, become larvae, mature and then turn into polyps within a few days is what makes Sommer extremely surprised. This means that these jellyfish have not disappeared, instead they are rejuvenated like a full-blown rejuvenation. Further research has found that not all lighthouse jellyfish will rejuvenate, their life cycle will still proceed normally. However, when faced with certain adverse conditions such as food scarcity, water temperature changes, sea water decrease in salinity or physical damage and many other adversities, they will fend for themselves. rejuvenate, turn into polyps and begin their life cycle once more. Theoretically, lighthouse jellyfish can reverse its life cycle continuously without limit of times, so it can be said that lighthouse jellyfish is an immortal life form and is also the only species in the world that can such a mechanism of life. Moreover, each time this rejuvenation process is performed, the lighthouse jellyfish can separate into hundreds of different polyps, which means that the current lighthouse jellyfish have “aged” very much. , may even exceed several thousand years old. Therefore, this species is also considered the longest living organism on the planet, if not completely immortal. It is widely believed that lighthouse jellyfish appeared during the Cretaceous period, and if so, lighthouse jellyfish in the ocean have lived for more than 100 million years. The lighthouse jellyfish is actually an invasive species, it originated in the Pacific Ocean and is thought to colonize oceans around the world through ballast water. Due to its small size, and not causing too many adverse reactions to the ecosystem, few people notice its invasiveness.

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”.

In recent years, stone grouper (or ninja fish, demon fish) has become a specialty that many people love. They are found to live most commonly in Quy Nhon (Binh Dinh), Khanh Hoa. Photo: HaisanTrungNam
