Are there any good special breeding and planting projects? Please tell me!

Mealworm or barley worm breeding is a relatively popular special insect breeding recently. You can check it out. If you are in Guangdong, you can find Pengxiang Mealworm Breeding Professional Cooperative in Xinfeng County, Guangdong. They are South China A relatively large yellow mealworm breeding base in the region.

1. The breeding and application prospects of mealworm

Tenebrio molitor. Insect taxonomy belongs to the order Coleoptera, the family Pleuropodidae, and the genus Pleuropoda. It has the characteristics of fast growth and high reproduction coefficient. Its main food is wheat bran, crop straw bran powder and waste vegetables. Also known as mealworms (so named because they are used as an additive in bread abroad), their protein content ranks first among all living animals. Mealworm as a species in nature.

There are 330,000 known species in China; countries around the world have begun to strengthen the development and utilization of insect resources. "Insect dishes" are very common. Some insect food developers in the UK and West Germany have developed and produced more than a dozen "insect drinks". Currently, my country is also conducting research on the development of mealworms. There are currently more than 1.8 million known insect species in the world. and achieved many results. On dining tables in Mexico, France, Australia, New Zealand and beyond.

Large-scale production project of mealworm. Utilize and transform organic waste resources, mainly crop straw. Reduce energy waste. The basic content of developing the emerging insect industry is to create employment opportunities for rural surplus labor and urban laid-off workers. Turn waste into treasure. Purify the ecological environment. Produce high-protein animal feed and promote the in-depth processing and comprehensive utilization of new mealworm varieties. The project is currently advancing towards industrialized deep processing on the basis of completing new variety selection, laboratory breeding, and industrial-scale production.

In order to promote the industrialization of the mealworm project as soon as possible. Implement standardization and institutionalization of project operations. At the same time, there is a unified rule for coordination with other departments. This enables franchisees to receive better, more detailed and thoughtful services, and provides relevant personnel with a convenient, fast and standardized operation method during the business development process. And use this as a guideline. Improve project operational efficiency. The company has specially compiled this information.

2. Analysis of the uses and broad market space of mealworms

According to research by relevant experts. It is also rich in nine essential amino acids and proteins. And consistent with the normal proportions of the human body. There is very huge room for development. Foods, beverages and condiments developed from fresh mealworm bodies or defatted proteins are constantly emerging. Insect pupae not only contain a large amount of chitin, antimicrobial peptide defensins and exogenous lectins that have special effects on the human body. Free amino acids, vitamins, mineral elements, unsaturated fatty acids and other nutrients. Easily absorbed and exploited. Insect food will be a complete nutritional food for mankind in the 21st century. Such as dishes, bread, biscuits, canned mealworm pupae, mealworm compound supplements, etc. Relevant experts predict that the large-scale production of insect pupa food will be an emerging industry after vegetables and eggs, creating a new energy field and an emerging project of the national vegetable basket project. Insect pupae are highly favored by consumers for their pure naturalness, pollution-free, delicious fragrance, high nutritional value and unique nourishing effect. Some high-end hotels in Beijing, Shanghai, Guangzhou, Changsha, Nanning and other places have already sold it. The price of insect pupae in various places continues to rise. At the New Century Hotel in Beijing, fried insect pupae are sold for 138 yuan per plate, and at the Tongchuan Road Aquatic Products Market in Shanghai, mealworm pupae are sold for 78 yuan per kilogram. There is often no stock available, so rare goods can be found. .

According to expert testing and analysis, the fat content of fresh insects is 28.20% and the protein content of fresh insects is as high as 61%. and 18 kinds of amino acids necessary for animal growth. Its various nutrients rank first among all types of food. According to feeding measurements. The nutritional value of 20 kilograms of mixed feed and 100 kilograms of green feed also contains phosphorus, potassium, iron, sodium, aluminum and other macroelements and a variety of trace elements. Each 100 grams of dry product contains 947.91 micrograms of amino acids. The nutritional value of 1 kilogram of mealworms is equivalent to 25 kilograms of wheat bran. It is known as a treasure house of protein feed. According to tests by relevant units, it is the best feed for breeding spiders, centipedes, scorpions, snakes and poultry and livestock. Practice has proven that using mealworms as feed can accelerate its growth and development, improve its reproductive rate, and improve its disease resistance.

Using mealworms to raise poultry has a survival rate of more than 95%. It can also be used as live feed to directly feed various high-grade aquatic fish, scorpions, forest frogs, soft-shell turtles, geckos, and birds. Feeding egg-laying poultry, etc. can increase the production of poultry. The egg rate is increased by half. Feeding spiders, whole scorpions and other animals will greatly increase their reproduction rate. Because mealworms contain high amounts of protein, amino acids, fats, sugars and other nutrients, are sweaty soft bodies, have strong vitality, and are easy to raise, they are selected as good feed by zoos and farms around the world. Use mealworms to feed Chinese forest frogs and sell them in two years. It has good commercial properties and high profitability. It is the main feed for artificial breeding of Chinese forest frogs. Frog farmers in Heilongjiang, Jilin and Liaoning provinces are very concerned about this.

As the saying goes. How can you give up enjoying any kind of delicious food? Food is the most important thing for the people. As a Chinese who knows how to eat.

Common insects. A delicious dish that I will remember endlessly. I'm constantly discovering innovative cuisine. It can also enhance physical fitness, beautify and rejuvenate. On weekdays it seems ordinary. Today, I was able to be served to the dining table in a grand manner. People's current dining tables are not only used to simply provide food and clothing.

Mealworm molitor has high nutritional value. Pupa contains 57% crude protein. 11 times that of milk. Vitamin B1 is 15 times that of milk, and the larvae contain 56.58% crude protein and 28.20% fat. Adult worms contain 64% crude protein (according to the "Chinese Medicine Science and Technology News" report). The total protein content is 7.8 times that of meat; the free amino acid content is about 50-100 times that of mammals. Exceeding the reference value proposed by FA A/WHO of 40% fat-soluble vitamins, ADEK is extremely rich in water-soluble vitamins B. 1800 times that of vitamin B2 milk and 52 times that of vitamin B6 milk. In addition, it has macro mineral elements such as calcium, potassium, sodium, magnesium, etc.; and trace mineral elements such as iron, zinc, copper, manganese, cobalt, chromium, selenium, boron, iodine, etc. The content of nutrients is richer than that of milk and meat. many. It is rich in 8 kinds of amino acids required by the human body, protein, phosphorus, iron, sodium, calcium and other macroelements and a variety of trace elements. The content is higher than that of milk and meat. It is rich in nutrients and can improve human immunity and resist fatigue. Delay aging, lower blood lipids, enhance physical fitness, anti-cancer and other effects. The effects are superior to existing market products. The development of insect chitin granules is the latest anti-cancer drug. Highly nutritious; well-known foreign biological products companies use mealworms to make nutritional and health care products. SOD extracted from mealworms is used as anti-aging, anti-wrinkle, whitening and other cosmetics. For example, Japan's recently developed anti-cancer drug Jiuduoshan is extracted from mealworm chitin. Foods (bread, cakes, etc.) made with mealworm powder have a delicious taste.

Currently. There are many people who flock to restaurants to eat insect meals. It can also be used for beauty and beauty. The bugs she was usually afraid of were on the plates in restaurants. Associating these wriggling bugs with delicious food, health care and beauty, a new style of food has emerged in Beijing and major cities. Such food increases nutrition at the same time. It seemed to be covered with a layer of mysterious light. But maybe some people still think so. A rather incredible thing. So, what are the benefits of eating insect meals? Does it make sense to say that it can be used for beauty? According to Professor Wang Guangya, an expert from the Academy of Preventive Medicine of the Chinese Nutrition Society, the protein in pupae is quite rich, because the insects that metamorphose into adults must have enough protein, so pupae are rich in protein. The Institute of Zoology of the Chinese Academy of Sciences and the School of Food Science of Jiangnan University, one of the most authoritative universities in the field of nutritional food in China, have refined an active nutritional protein from the body of an insect that cannot be invaded by bacteria in nature, and successfully developed it as a raw material Purely natural, non-toxic and harmless fourth-generation health care product - insect active protein. It is rich in chitin and antimicrobial peptides, and has an inhibitory effect on diseases of affluence and civilization such as fatty liver. It can strengthen liver function, remove liver endotoxins and excess fat, and activate liver cells and liver tissue. Because the protein metabolism provided by the liver is disordered, plasma protein will decrease. Insect protein can supplement the active protein needed by the liver, and regulated protein can supplement the active protein needed by the liver and regulate protein metabolism. In addition, insect active protein can also eliminate excess harmful cholesterol, lower blood sugar and blood pressure, improve microcirculation, purify blood, and restore and prevent various complications. Insect active protein is the fourth generation health product, a high-tech natural nutritional product that is popular in the world.

A professor from the Institute of Entomology at Sun Yat-sen University also pointed out that insects are indeed very nutritious. Insects are rich in protein, unsaturated fatty acids, chitin (chitin), vitamins, trace elements, biologically active substances and other nutrients, which are particularly valuable. There are many nutrients that are unique to insects. The protein content of insects is not only many times higher than that of poultry and livestock, but the fat content is much lower than that of poultry and livestock. Eating them will not cause an increase in cholesterol levels. In addition, insects have very good health effects, and some can even cure diseases. Many female diners eat these worm chrysalises because they are rich in protein, and regard them as a good product for both health and beauty. If you love food and curious things, then a worm meal can satisfy your curiosity.

After laboratory analysis. It can also be used as roughage to feed livestock and poultry such as pigs, cattle, chickens, ducks, fish, etc. Applying high-efficiency bio-organic fertilizers with insects as the main raw material can not only enhance soil fertility. It can also reduce agricultural production costs. To improve the agricultural ecological environment, mealworm manure contains 3.37% nitrogen, 1.04% phosphorus and seven trace elements including zinc, boron, manganese, iron, magnesium, calcium and copper. Mealworm manure is both a good organic fertilizer. Increase crop yields and improve the quality of agricultural products. Improve soil structure. Promote the sustainable development of the planting industry. At present, the supply of truly high-efficiency bio-organic fertilizer products on the market is not large, and there are instability problems, which cannot meet the needs of efficient agricultural production. Therefore, this project uses insect excrement as the main raw material to produce high-efficiency bio-organic fertilizers, which has good market prospects.

Passed measurement. Total nitrogen content is 3.37%. Total nitrogen content is 1.41%. Its nutritional content is comparable to cottonseed cake. The crude protein content in the excrement of mature mealworm larvae is 24%. The total P:O content is 1.04%. Fat content is 7.65%. The contents of zinc, boron, manganese, iron, magnesium, calcium and copper in excrement are 322ppm, 14.6ppm, 109ppm, 460ppm and 0.31% respectively

3. The necessity and feasibility of large-scale cultivation of mealworm

It is in line with the industrial policy vigorously supported by the country. The large-scale production and industrialization project of Tenebrio molitor is a new high-tech and environmentally friendly product of comprehensive utilization of straw. It is listed as an industry and product that focuses on supporting development, technological transformation, infrastructure construction and production. It has also become a scientific research project of Shandong Agricultural University. This is one of the special funding projects of the National Agriculture, Animal Husbandry and Fishery Harvest Plan of the Ministry of Agriculture. The state formulates high-tech industry development plans and industrial policies.

Develop new ways to utilize and transform agricultural organic waste resources, mainly crop straws. China is a large agricultural country. Less than 20% was consumed for raising large livestock, less than 10% was used for firewood, and the rest was burned on site or piled up for a long time to naturally decay. And hinder traffic. pollute the environment. By utilizing and converting these organic wastes, 500-600 million tons of various crop straws and seedlings are produced every year. It also causes a waste of resources. Block the river. And making it produce certain economic benefits is one of the priorities of governments at all levels and is also the eager hope of farmers. Mealworms can fully convert industrial and agricultural organic wastes (chips) such as straw into substances that can be used by humans, solving the problems of waste of a large amount of straw and other waste resources and environmental pollution, and establishing a new waste material that is different from the traditional ecological food chain. Ecosystem has opened up a new way for humans to obtain protein.

Large-scale promotion. Increase employment opportunities. Mealworms are highly adaptable. Both industrial farming and dispersed farming are possible. Centralized processing. It is particularly suitable to adopt the business model of company + base + farmers, and can form a new industry. Breeding techniques are easy to master. Suitable for dispersed feeding. Regional-scale development is easy to succeed and can fully become the leading project of agricultural industrialization in a county or city. Taking household farming as an example, every 5 tons of commercial insects produced can create 3 more jobs. The formation of an industry can effectively alleviate the employment pressure in rural and urban areas. This project not only has significant economic benefits, but also has significant social benefits.

Mealworm feed does not consume grain. In turn, various livestock and poultry and various economic animals can be raised. Through the intermediate link of mealworm. It has opened up a new path for agricultural industrialization. It can also convert feed that cannot be converted by large livestock and poultry into high-quality protein feed. People use small domestic animals like mealworms as a springboard. It solved the long-term problem of dividing food between humans and animals. Transform the traditional single-item single-ring agricultural production model into a multi-item multi-ring agricultural production model. Make agricultural production itself form an industrial chain.

4. Analysis of Economic Benefits of Cultivating Mealworm Molitor

It can lay eggs continuously for 60-90 days (calculated as 60 days). It can pick up 15 eggs in 60 days, and can lay 25 eggs at a time. box. Eggs are collected every 4 days. Adult worms weigh one pound per box. Based on our purchase price of 10 yuan/kg for live worms and 30 yuan/kg for dried worms, the economic benefits are as follows: 100 kilograms of seed worms can emerge into at least 25 kilograms of adult worms after 2040 days of raising depending on the season. To raise 100 kilograms of seed insects introduced from us. Now based on my breeding practice. Raising can produce 8-10 pounds of commercial insects. 1. Benefit analysis of producing commercial insects: Commercial insects can be produced in this cycle (3 months): 25 boxes, 22 times, 8 kilograms/box = 4,400 kilograms. According to our lowest protective price of 10 yuan/kg, the income can be 22,000 yuan. 1 kilogram of commercial insects can produce 0.6 kilograms of insect excrement. The price here is 0.25 yuan/jin. The income from selling insect excrement is: 0.64400 kilograms, 0.25 yuan = 660 yuan. Excluding costs, wheat bran, vegetables, labor and electricity charges of 2.5 yuan per kilogram, the cost is 11,000 yuan, and the net income is 11,660 yuan. According to three cycles in the first year, excluding the average initial equipment investment of 3,000 yuan and the introduction fee of 5,600 yuan, the net income can be 26,380 yuan. In the coming year, after four periods of maintenance, the net income will be 46,640 yuan. It is more efficient to raise pigs or chickens with mealworm excrement and slough. If the amount of seed reserved is increased when the eggs are picked for the first time, the profit can be doubled. In addition, for every ton of live insects produced, 1.5 kilograms of insect chitin can be produced, and the market price is 2-3 yuan per gram.

5. Understanding and feeding cycle of mealworms

Mealworms are completely metamorphosed insects. 1.4-1.8 cm long. The head is frontal. The head, thorax and feet are light brown, indicating four metamorphoses: adult, egg, larvae and pupa. The adult body is long and flat. Dark brown with metallic luster. The sides of the labial base do not extend beyond the tactile base. Adult beetles in the process of emergence. The abdomen and elytra are milky white. At first, the insect is immature and unwilling to move. After 2-3 days, the color becomes darker, the elytra become hard, flexible but not flying, and it crawls quickly. After careful feeding, the adult colonies mate and lay eggs. Adults lay 2-4 eggs each time, and each female lays about 300-600 eggs, which are scattered on the screen at the bottom of the feed. The adult period is about 60 days. Egg white oval, about 1 mm in size. The egg stage lasts about 8-10 days. The larvae are brownish-yellow, 2-3 cm long, with obvious body segments, 3 pairs of thoracic legs, and a pair of tail processes on the ninth abdominal segment. The larvae are yellow-white when they hatch, gradually turning into brownish-yellow. They molt once every 9 days on average, and each molt is one instar. They molt 7 times and pupate on the surface of the feed after the last molt. The larval stage lasts about 60 days. The pupa is white and later turns white to yellow with obvious body segments. The pupa stage lasts 12-15 days.

Larvae: The appearance is very similar to wireworms and ground beetles. Lip base obvious. Herbivorous. Newly hatched larvae are milky white. Later, it sheds its skin and becomes slender. That is, there is an obvious suture between the upper lip and forehead. Approximately 2 mm long. Each shed of skin is one instar. It turns brown and yellow. The mature larvae are 2030 mm long, with obvious body segments, 3 pairs of thoracic legs, and a pair of tail processes on the ninth abdominal segment. The large insect is 33.5 mm wide and weighs 0.130.24 grams. Pupation occurs on the surface of the feed during the final molt. The larval stage lasts about 50-70 days.

Pupa: The pupa that has just transformed from mature larvae is milky white. Very childish. Then the body color turns grayish white. Typical naked pupa. Pupa length 1520 mm. Weighs about 0.150.25g/piece. There are light-colored vertical strips on the back and the body surface is soft. The body surface becomes harder. Approximately 3mm wide. Mouth black. There are papillae on the side of the abdomen (the papillae of male pupae are not obvious, the base is healed, and the ends extend to the rear; the female pupae are obvious, the ends are flat, slightly horny, bifurcated, and significantly curved). The thoracic segments are large, and there are rudimentary wings on the sides. The appendages and head segments are also large and have a pair of black eyespots.

Adult: The first pair of wings of newly fledged adults is soft. Then yellow. Gradually turns to black with metallic luster. The sides of the labial base do not exceed the tactile base and are white. tan. The head is frontal. During the emergence process of the adult insect, the head, thorax and feet are light brown, the abdomen and elytra are milky white. At first the insect body is immature and reluctant to move. The elytra are black and become hard and flexible. The second pair of wings are membrane wings, but they cannot fly due to degeneration. , crawling quickly. After careful feeding, the adult worms mate and lay eggs. The adults lay 24 eggs each time, and each female lays about 300-600 eggs, which are scattered under the screen at the bottom of the feed.

The adult stage lasts about 3090 days. The adult looks like a firefly, with a body length of 1018 mm and a width of 46 mm. The body weight is 0.10.2 grams per animal. The body is divided into three parts: head, chest and abdomen, with 13 segments. The head has 1 segment and a pair of antennae. The 23 segments at the end are enlarged and rod-shaped. The mouth is located on the lower side of the head. The head is small, partially embedded in the chest, with a pair of black jaws and chewing mouthparts. The thorax has 3 sections, and there is no obvious dividing line between the pronotum and lateral plates. They are mostly healed, and the sutures on the sides of the prothorax and abdomen are obvious. The abdomen has 8 segments, with 5 abdominal segments visible and 1 segment at the tail. The male worm has a copulatory organ hidden in it, and the female worm has an ovipositor hidden in it.

Eggs: Very small. Long oval shape. The short diameter is about 0.30.8 mm. The outer surface of the egg is an egg shell. It is filled with milky white intraegg substance. The egg period is 810 days. Adults lay the most eggs at 25℃ to 32℃, which are milky white. Long diameter 0.71.2 mm. The inner layer is the vitelline membrane. The quality is also high. They seldom mate and lay eggs when the temperature is lower than 15℃, but they do not mate or lay eggs when the temperature is lower than 10℃.

6. Seed insects and feed required for cultivating mealworms.

1. Breeding conditions

1) Seed insect cultivation The most important seed insect of Mealworm molitor. According to the technical requirements for the cultivation of mealworm. Get rid of pests and diseases. Synchronize the reproduction of each insect stage, and adult larvae, pupae and adults can all be used as seed insects. Raised to different worm stages. Carefully select pupae and adults. Sieve the eggs. Achieve purification and rejuvenation. After purchasing the adult larvae, put them into a wooden tray filled with wheat bran and add fresh vegetables. Carefully observe the pupation situation. When pupation occurs in the tray, place the sieve tray into a wooden tray containing feed until the pupae emerge into adults. At this time, you can also buy pupae, put them together with the pupae that have matured within two days, and put every 0.5 kilogram of pupae in a sieve tray filled with wheat bran, and then put them in a wooden tray filled with feed. Number them and put them on the shelf. During their emergence, pay attention to remove dead pupae. Another example is to buy adult worms and place them in a sieve tray containing feed. Every 7 days, sift out the adults and change the tray. The sieved feed is mixed with eggs, placed in a wooden tray, and continues to hatch. After careful selection and raising, the worms of each stage can be used as seed worms, but it is best to use larvae as seed worms, which are also easy to transport.

2) Feed The main feed of mealworm is wheat bran. radish. vitamins. To speed up reproduction and growth, some auxiliary feeds such as bran, various types of cakes, and straw-type feeds can also be used. The main vegetables are cabbage. Cabbage and other green leafy vegetables are fine. These feeds can satisfy the insect's need for protein. Trace elements and moisture requirements. In order to purify the rejuvenated population. A small amount of glucose powder, fish meal, etc. can be added to the feed. Every 0.5 kilogram of mealworms can eat 1.5 kilograms of wheat bran and 1 kilogram of vegetables in one generation cycle.

3) Equipment

1. A breeding room is required for cultivating mealworms. Heating and insulation are needed in winter. The size of the breeding room. One room can support 300-500 dishes. It should be light and ventilated. It depends on how many mealworms are cultured. Normally every 20 square meters.

2. The wooden tray for raising mealworms is a drawer-shaped wooden tray. Specifications are 80cm long. Height 8cm. The board thickness is 1.5 cm. It needs to be placed in a wooden tray, usually rectangular. Width 40cm. The bottom is nailed with fiberboard. The sieve tray is also rectangular. The length, width, and height are 75 cm, 35 cm, and 6 cm respectively, and the board thickness is 1.5 cm. The bottom is nailed with a 10-mesh iron screen and three-ply laths. The wood used to make the feeding tray is preferably soft wood and has no peculiar smell. In order to prevent insects from crawling out, plastic strips should be attached to the four frames of the breeding tray. Make a wooden frame. Prevent tilting or tipping. Then you can put the feeding trays on the shelves in order.

3. Place the feeding tray wooden frame according to the feeding amount and the number of feeding trays. Use square logs to connect the wooden frames and secure them.

4. Use iron screens of different thicknesses for the egg tray and separation sieve. 121416 are used to separate insects of different age groups.

5. The temperature inside the breeding room is required to be maintained between 15-25 degrees Celsius in winter and summer. Insects will not eat or grow below 5 degrees Celsius. The ground should not be too wet. If you don't raise it in winter, it can survive the winter naturally. Ventilation is required in summer. There should be a thermometer and hygrometer indoors. If the temperature exceeds 35 degrees Celsius, the insect body will heat up and burn to death. Humidity should be maintained between 50-70%. Keep warm in winter.

2. Breeding technology

1) Adult stage; the process of emerging from pupa to adult takes about 3-7 days. The abdomen and tail feathers come out. Because the pupae emerge simultaneously. The newly emerged adults are very immature.

After about 5 days, the body color becomes darker, and the head, chest, feet and wings are first feathered. Therefore, all feathering can be completed within a few days. Not much activity. The elytra become stiff. Male and female adults usually gather in a dark place to mate, and the mating time is long. When laying eggs, the tail of the female worm is inserted into the sieve hole to lay eggs. It is best not to stir at will during this period. When you find a layer of eggs attached to the bottom of the sieve tray, you can change the tray. At this time, sift the eggs of the adult insects and place them in another plate containing feed, and remove the dead insects. Change the egg plate every 4 days. The adult survival period is 60-90 days. Adults during the spawning period require a lot of nutrients and water, so wheat bran and vegetables must be added in time, and some fish meal can also be added. If there is insufficient nutrition, the adults will bite each other, causing losses.

2) Egg stage; adults lay eggs in wooden trays containing feed. The larvae will hatch naturally. It should not be turned over. The 1st instar has been born. Replace the wooden tray containing eggs and put it on the shelf. Be observant. Prevent damage to eggs or harm to hatching larvae. When larval skin appears on the surface of the feed.

3) Larval stage; eggs hatch into larvae. The disc in which adult worms lay their eggs. When the molted body is more than 0.5 cm long. The density should not be too high. The period before pupation is called the larval stage. After hatching 7-9 days. Add wheat bran and fresh vegetables. Place 1 kg of larvae in each wooden tray. Prevent the insects from biting each other due to insufficient feed and extrusion. As the larvae gradually grow up, they should be divided in time. Wheat bran is the main feed for the larvae, and it is also a habitat, so the feed must maintain a natural temperature. Under normal circumstances, when the temperature is high, the larvae mostly move on the surface of the feed, and when the temperature is low, they burrow into the lower layer to live. The thickness of the feed in the wooden tray should be within 5 cm. When the feed gradually decreases, use a sieve to filter out the insect feces and add new feed. When 1-2 instar larvae sift feces, a 60-mesh sieve should be used to prevent larvae from leaking through the sieve holes. You must first prepare a wooden tray to hold the new feed, and put the screened larvae into the wooden tray while sifting. To grow, mealworm larvae need to break through the outer skin and molt again and again before they can grow up. The larvae need to shed their skin 7-12 times. Each time they shed their skin, the insect body grows and the larvae grows one instar. On average, they shed their skin once every 8 days. When the larvae molt, the epidermis first splits from the thoraco-dorsal seam, and the head, thorax, feet, and then the abdomen and tail gradually slough out. The larvae usually molt on the surface of the feed, and then burrow into the feed after molting. The newly molted larvae are milky white and have a delicate skin.

4) Pupa stage: The larvae pupate on the surface of the feed. Before pupation, the larvae crawl to the surface of the feed. Pupation is completed during the last molt. Pupation can be completed within seconds. The newly formed pupae are white and yellow. The abdominal segments move. Turns into dark yellow. There are differences among individual larvae. After lying still, the body of the larvae slowly expands and contracts. The pupal body is slightly longer. The pupal body gradually shortens. It is reflected in the sequence of pupation time and the strength of individual abilities. Freshly pupae and larvae live together in a wooden tray. The pupa is easily bitten by the larvae on the chest and abdomen, and eats the internal organs and becomes an empty shell. Some pupae are infected by viruses during the pupation process and become dead pupae after pupation. This is Frequent inspection is required. If this situation is found, the space can be sprayed with 0.310-6 bleach solution to disinfect and sterilize. At the same time, the dead pupae will be picked out and disposed of in time. When picking pupae, put the pupae that have matured within 2 days in the same sieve tray containing feed, insist on synchronous reproduction, and concentrate on emerging into adults.

3. Management measures

During the cultivation of mealworms. It is related to issues such as the speed of mealworm reproduction, insect quality, and economic benefits. It is very important to master breeding techniques and management measures.

It is best to disinfect outside the door. 1. Non-breeding personnel are prohibited from entering the breeding room. People who must enter indoors. The four metamorphoses are an important link. You can master the breeding technology. The life cycle of the mealworm. Master the time, shape, and characteristics of each metamorphosis. 3. Feed should be fresh. Green vegetables do not rot. Bran does not deteriorate. Every time you shed your skin. Add new feed. There are eggs and insect feces at the bottom of the adult stage feed. Change the disk promptly. Four larval stages. Change feed and screen manure promptly. Prone to mold. to larvae. Glucose powder, vitamin powder, and fish meal should be added appropriately to the feed. Feed fresh vegetables every day. 5. In order to speed up reproduction and growth. Adult beetle after emergence. 6. The breeders should check the status of each insect stage every day. Prevent bacterial infection. If pests or dead insects are found, they should be removed promptly. Only in this way can the success of mealworm breeding be ensured. The cultivation of yellow mealworms should be carried out according to plan. The number of feeding insects and the number of larvae of each instar must be fully recorded.
