What are the entrepreneurship suitable for rural areas?

If you start a business in the countryside, you must extend or expand your development based on the superior resources in the countryside. Now the rural land resources are constantly appreciating. Although more and more rural people are unwilling to farm, the trend is that more and more individuals, collectives and consortia will concentrate rural land in the form of contracting, leasing and purchasing, and then carry out rural economic development.

There are many land resources available in rural areas, with relatively low cost, low labor cost and wide available resources. Consider planting or breeding. However, the development space of traditional aquaculture is small, so let's March in the direction of characteristic aquaculture.

Breeding of Tenebrio molitor and barley nymph is a new type of special insect breeding, which has the characteristics of short cycle, high yield, large income and broad market prospect. Want to know about insect breeding, you can find Tenebrio molitor breeding professional cooperative in Xiang Peng, Xinfeng County, Guangdong Province, which is the largest insect breeding base in South China.

Breeding and application prospect of Tenebrio molitor

1. Breeding and application prospect of Tenebrio molitor

Tenebrio molitor belongs to COLEOPTERA, Tenebrionidae and Tenebrionidae in taxonomy. It has the characteristics of fast growth and high reproduction coefficient. Its main foods are wheat bran, crop straw bran powder and waste vegetables. Also known as breadworm (named after being used as an additive for bread abroad), its protein content ranks first among all living animals. Tenebrio molitor is a species in nature.

There are 330,000 known species in China; All countries in the world have begun to strengthen the development and utilization of insect resources. "Insect cuisine" is very common. Some insect food developers in Britain and West Germany have developed and produced more than a dozen "insect drinks". At present, China is also developing and studying Tenebrio molitor. At present, there are more than 1.8 million known insect species in the world. And achieved a lot of results. On the dining tables in Mexico, France, Australia, New Zealand and other places.

Scale production project of Tenebrio molitor. Utilization and transformation of organic waste resources mainly based on crop straw. Reduce energy waste. The basic content of developing emerging insect industry is to create employment opportunities for rural surplus labor and laid-off workers in cities. Turn waste into treasure. Purify the ecological environment. Produce animal high-protein feed and promote the deep processing and comprehensive utilization of new Tenebrio molitor varieties. Based on the completion of new variety breeding, laboratory breeding and industrial scale production, the project is now advancing towards industrial deep processing.

In order to realize the industrialization of Tenebrio molitor project as soon as possible. Standardize and institutionalize the project operation. At the same time, there are uniform rules for coordination with other departments. So that franchisees can get better, more meticulous and more thoughtful service, and provide convenient, fast and standardized operation methods for relevant personnel in the process of business development. And take this as the standard. Improve the operational efficiency of the project. The company has specially compiled this information.

Second, the use and broad market space analysis of Tenebrio molitor

According to the research of relevant experts. It is also rich in nine essential amino acids and protein. And in line with the normal proportion of the human body. There is huge room for development. Foods, beverages and condiments developed from fresh Tenebrio molitor or defatted protein are constantly emerging. Insect pupa not only contains a large number of chitin, antimicrobial peptide defensins and lectins that have special effects on human body. Free amino acids, vitamins, mineral elements, unsaturated fatty acids and other nutrients. Easy to be absorbed and utilized. Insect food will be all nutritious food for human beings in 2 1 century. Such as dishes, bread, biscuits, canned Tenebrio molitor pupae, Tenebrio molitor compound supplements, etc. Experts predict that the large-scale production of insect pupa food, an emerging industry after vegetables and eggs, has created a new energy leading city and a new vegetable basket project in China. Insect pupa is favored by consumers because of its natural, pollution-free, fragrant and delicious, high nutritional value and unique nourishing effect. Some high-end hotels in Beijing, Shanghai, Guangzhou, Changsha and Nanning have all been sold. The price of insect pupae is rising all over the world. In Beijing New Century Hotel, fried insect pupae are sold for 138 yuan, while in Shanghai Tongchuan Road Aquatic Products Market, one kilogram of bread insect pupae is sold to 78 yuan, and there are often no goods available, so imported products can live in it.

According to experts' detection, the protein content of fresh worms with 28.20% fat content is as high as 6 1%. And 18 essential amino acids for animal growth. Its various nutrients rank first among all kinds of foods. According to the feeding experiment. The nutritional value of 20 kg compound feed and 100 kg green feed, in addition, it also contains major elements such as phosphorus, potassium, iron, sodium, aluminum and various trace elements. Every 65438 000 grams of dried product contains 947.38 0 micrograms of amino acids. The nutritional value of 1 kg Tenebrio molitor is equivalent to 25 kg wheat bran. Known as the treasure house of feed in protein, it is the best feed for raising spiders, centipedes, scorpions, snakes, poultry and livestock according to the test of relevant units. Practice has proved that using Tenebrio molitor as feed can accelerate its growth and development, improve its reproductive rate and disease resistance. Using Tenebrio molitor to raise young birds, the survival rate is over 95%, and it can also be used as live feed to directly feed and raise various aquatic high-grade fish, scorpions, forest frogs, turtles, geckos, birds and so on. Raising laying birds can increase the laying rate by half, and raising spiders, scorpions and other animals can greatly improve their reproductive rate. Tenebrio molitor is selected as a good feed by zoos and farms all over the world because of its high nutritional components such as protein, amino acids, fat and sugar. Sweaty and soft, strong vitality, easy to raise. In China, Tenebrio molitor was fed to Rana chensinensis in China for two years. The products were good and the benefits were high. China forest frog is the main feed for artificial breeding, and frog farmers in Heilongjiang, Jilin, Liaoning and other provinces are extremely concerned about it.

As the saying goes. How can you give up enjoying any kind of food? Bread is the pillar of life. As a China person who knows how to eat.

Common insects. Become a delicious food I can't forget. I found it in innovative food. It can also strengthen your health, beauty beauty. On weekdays, it seems ordinary. I can't believe I was put on the table in public today. At present, people's dining tables are not only used to simply solve the problem of food and clothing.

Tenebrio molitor has high nutritional value. Pupa contains 57% crude protein. 1 1 double milk. Vitamin B 1 is 0/5 times that of milk, and the larvae contain 56.58% crude protein and 28.20% fat. Adults contain 64% crude protein (reported by China Medical Science and Technology News), of which the total amount of protein is 7.8 times that of meat; The content of free amino acids is about 50- 100 times that of mammals. The contents of fat-soluble vitamin ADEK and water-soluble vitamin B group are extremely rich, exceeding the reference value proposed by FA A/ WHO by 40%. 1800 times of vitamin B2 milk and 52 times of vitamin B6 milk. In addition, it also contains major mineral elements such as calcium, potassium, sodium and magnesium. The nutritional components of trace mineral elements such as iron, zinc, copper, manganese, cobalt, chromium, selenium, boron and iodine are much richer than milk and meat. It is rich in 8 kinds of amino acids needed by human body, and the contents of macro elements and trace elements such as protein, phosphorus, iron, sodium and calcium are higher than those of milk and meat. It is rich in nutrition, and has the effects of improving human immunity, resisting fatigue, delaying aging, reducing blood fat, strengthening physique and resisting cancer. The effect is better than the existing market products. Developing insect chitin particles as the latest anticancer drugs. High nutrition; Famous foreign biological products enterprises all use Tenebrio molitor to make nutritional and health products. SOD extracted from Tenebrio molitor is used as anti-aging, anti-wrinkle and whitening cosmetics. For example, many anticancer drugs recently developed in Japan are food (bread, cakes, etc. ) made of Tenebrio molitor powder extracted from Tenebrio molitor chitin, with fresh taste.

At present. Many people flock to restaurants to eat worm meals. Not bad, beautiful. Once the bugs she is usually afraid of are served on the plates in the restaurant. Combining these crawling insects with delicious food, health care and beauty, Beijing and major cities have created a new diet. Such food increases nutrition at the same time. It seems to be covered by a mysterious light. But maybe some people will think. A rather strange thing. So, what are the benefits of eating the bottom of a worm meal? Can it be beautified and reasonable? According to Professor Wang Guangya, an expert from the Academy of Preventive Medicine of China Nutrition Society, protein in insect pupae is quite rich, because it must have enough protein to degenerate into an adult insect, so pupa vegetables are rich in protein. The Institute of Zoology of Chinese Academy of Sciences, one of the most authoritative universities in nutrition and food science in China, cooperated with the College of Food Science of Jiangnan University to extract an active nutritional protein from an insect that bacteria can't invade in nature, and successfully developed the fourth generation of pure natural, non-toxic and harmless health care products-insect active protein. Rich in chitin and antimicrobial peptides, it has inhibitory effect on fatty liver and other rich diseases. It can strengthen liver function, remove liver endotoxin and excess fat, and activate liver cells and liver tissues. Because the metabolism of protein provided by the liver is disordered, it will cause the decrease of plasma protein. Insect protein can supplement the active protein needed by the liver, and regulatory protein can supplement the active protein needed by the liver and regulate protein metabolism. In addition, insect active protein can also remove excess harmful cholesterol, lower blood sugar and blood pressure, improve microcirculation, purify blood, and recover and prevent various complications. Insect active protein is the fourth generation of health care products, and it is a high-tech natural nutrition that is popular all over the world. A professor from the Insect Research Institute of Sun Yat-sen University also pointed out that insects do contain rich nutrients, such as protein, unsaturated fatty acids, chitin vitamins, trace elements and bioactive substances. Many nutrients are particularly valuable. The protein content of insects is not only many times higher than that of livestock meat, but also the fat content is much lower than that of livestock meat. Eating them will not cause an increase in cholesterol content. In addition, insects have good health care functions, and some can even treat diseases. Many female diners are attracted to eat these insect pupae, because they are rich in protein, which is regarded as a good product for health care and beauty. If you like food and curiosity, then a bug meal can satisfy your curiosity.

After laboratory analysis. It can also be used as roughage to feed pigs, cattle, chickens, ducks, fish and other livestock and poultry. Applying high-efficiency bio-organic fertilizer with insects as the main raw material can not only enhance soil fertility. But also can reduce the agricultural production cost. To improve the agricultural ecological environment, Tenebrio molitor dung contains 3.37% nitrogen, 0/.04% phosphorus, and seven trace elements of zinc, boron, manganese, iron, magnesium, calcium and copper. Tenebrio molitor dung is a good organic fertilizer. Increase crop yield and improve the quality of agricultural products. Improve soil structure. Promote the sustainable development of planting industry. At present, the supply of real high-efficiency bio-organic fertilizer products in the market is not large, which is unstable and can not meet the needs of high-efficiency agricultural production. Therefore, the high-efficiency bio-organic fertilizer produced by this project with insect manure as the main raw material has a good market prospect.

By measurement. The total nitrogen content is 3.37%. The total nitrogen content is 1.4 1%. Its nutritional components are equivalent to cottonseed cake. The crude protein content in the feces of mature larvae of Tenebrio molitor is 24%. Total phosphorus: oxygen content is 65438 0.04%. The fat content is 7.65%. The contents of zinc, boron, manganese, iron, magnesium, calcium and copper in excreta were 322ppm, 65438±04.6 ppm, 65438±009 ppm, 460ppm and 0.365438 0% respectively.

Third, the necessity and feasibility of raising Tenebrio molitor on a large scale

In line with the industrial policy strongly supported by the state. The large-scale production and industrialization project of Tenebrio molitor belongs to high-tech and comprehensive utilization of straw environmental protection products. It is listed as industries and products that mainly support development, technological transformation, capital construction and production. At present, it has also become a scientific research project of Shandong Agricultural University. This is one of the special funded projects of the national harvest plan of agriculture, animal husbandry and fishery of the Ministry of Agriculture. The state formulates development plans and industrial policies for high-tech industries.

It opens up a new way for the utilization and transformation of agricultural organic waste resources, mainly crop straws. China is a big agricultural country. Less than 20% is used to feed large livestock, less than 10% is used as firewood, and the rest is burned locally or naturally decayed after long-term accumulation. It also hinders traffic. Pollution the environment. Using and transforming these organic wastes, we can produce 500-600 million tons of crop stalks and vines every year. It is not only a waste of resources. Block the river. And make it produce certain economic benefits, which is one of the priorities of governments at all levels and the ardent hope of farmers. Tenebrio molitor can fully convert organic wastes (sawdust) from industry and agriculture into substances that can be used by human beings, solve the problems of waste of sawdust resources such as straw and environmental pollution, establish a new sawdust ecosystem different from the traditional ecological food chain, and open up a new way for human beings to obtain protein.

Large-scale promotion. Increase employment opportunities. Tenebrio molitor has strong adaptability. Industrial farming and decentralized farming can be adopted. Centralized processing. It is especially suitable for adopting the model of company+base+farmer, which can form new industries. Breeding techniques are easy to master. Suitable for scattered feeding. Regional scale development is easy to succeed, and it can become the leading project of agricultural industrialization in one county and one city. Taking family rearing as an example, every 5 tons of commercial worms can increase 3 jobs, which can effectively alleviate the employment pressure in rural and urban areas after the industry is formed. This project has not only remarkable economic benefits, but also remarkable social benefits.

Tenebrio molitor feed does not consume food. In addition, all kinds of livestock and poultry as well as all kinds of economic animals can be raised. Through the intermediate link of Tenebrio molitor. It has opened up a new road for agricultural industrialization. Can convert the feed that cannot be converted by large livestock and poultry into high-quality protein feed. People use breeding Tenebrio molitor as a springboard. Solved the long-standing problem of food distribution for people and livestock. Transform the traditional single-ring agricultural production mode into multi-ring agricultural production mode. Make agricultural production itself form an industrial chain.

Fourth, the economic benefit analysis of feeding Tenebrio molitor

It can continuously lay eggs for 60-90 days (calculated as 60 days), catch eggs 15 times within 60 days, and lay eggs for 25 boxes at a time. Eggs are picked every four days. Adults are a kilo a box. According to the purchase price of live worms 10/ kg and dry worms 30 yuan/kg, the economic benefits are as follows: 100 kg of seed worms can emerge into at least 25 kg of adults after 2040 days' rearing according to different seasons. Introduce seed insects 100 kg from our place. According to my breeding practice. Feeding can produce 8- 10 kg of commercial insects. Benefit analysis of using 1 to produce commercial insects: during this period (3 months), commercial insects can be produced: 25 boxes of 22 times 8 kg/box = 4,400 kg. According to our lowest protection price 10 yuan/kg, the income can be 22,000 yuan. 1 kg commercial insects can produce 0.6 kg insect dung, where the price is 0.25 yuan/kg, and the income from selling insect dung is 0.64400 kg 0.25 yuan = 660 yuan. Regardless of cost, wheat bran, vegetables, artificial electricity, etc. 2. If the cost per catty in 5 yuan is 1 1000, the net income can be 1 1660 yuan. According to the three cycles in the first year, excluding the average equipment investment of 3,000 yuan and the introduction fee of 5,600 yuan, the net income in the second year is 26,380 yuan, and the net income in the third year is 46,640 yuan. For example, it is better to raise pigs or chickens with Tenebrio molitor dung and insect slough. For example, if the seed reserve is increased for the first time, the profit can be doubled. In addition, for every ton of live worms produced, 1.5 kg of chitin can be produced again, and the market price is 2-3 yuan per gram.

Verb (abbreviation of verb) Understanding and feeding cycle of Tenebrio molitor

Tenebrio molitor is a completely abnormal insect. Length 1.4- 1.8 cm. The head is protruding forward. The head, chest and feet are light brown, that is, adults, eggs, larvae and pupae. Adults are long and flat. Dark brown with metallic luster. Both sides of the base of lip shall not exceed the tactile base. Adults are in the process of eclosion. The abdomen and COLEOPTERA are milky white. At first, the worm was immature and unwilling to move. After 2-3 days, the color becomes darker, COLEOPTERA becomes hard, elastic but does not fly, and the crawling speed is accelerated. After careful feeding, adult groups 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 stage is about 60 days. Egg white is oval, about 1 mm in size. The egg period is about 8- 10 days. Larvae is brown, 2-3 cm long, with obvious body segments, 3 pairs of chest and feet, and a pair of caudate protrusions on the 9th abdominal segment. The larvae are yellow-white when they hatch and gradually turn brown. Molting once every 9 days, one year old at a time. * * * molt for 7 times, and pupate on the feed surface after the last molting. The larva stage is about 60 days, and the pupa is white, then turns white and yellow, with obvious body segments. The pupal stage is 12- 15 days.

Larvae: It looks very similar to Flammulina velutipes and Eupolyphaga Seu Steleophaga. The bottom of the lips is obvious. Phytophagy. The newly hatched larvae are milky white. The body is slender after molting. There is a clear seam between the upper lip and the forehead. It is about 2 mm long. Every molting is one year old. It turns brown, and the mature larva is 2030mm long, with obvious body segments, 3 pairs of chest and feet, and a pair of caudate protrusions on the ninth abdominal segment. The worm is 33.5mm wide and weighs 0.130.24 g. When molting for the last time, it pupates on the surface of feed. The larval stage is about 50-70 days.

Pupa: a pupa that has just changed from a mature larva, milky white. Very immature. After that, the body turned gray. Typical naked pupa. Pupa length1520mm. The weight is about 0. 150.25g/ piece. There are light longitudinal strips on the back, and the body surface is soft. Harden the body surface. About 3 mm wide. Darkmouth. There is a mastoid on the ventral side (the mastoid of male pupa is not obvious, the base is healed, and the end extends backward; The female pupa is obvious, the end is flat, slightly keratinized, bifurcated and obviously arched. ) The chest segment is large, with embryonic wings and appendages on the side, and the head segment is also large, with a pair of black eye points.

Adult: The newly emerged adult 1 has soft wings. Then yellow. It gradually turns black with metallic luster. Both sides of the lip base are not more than the tactile base, which is white. Yellow brown. The head is protruding forward. During eclosion, the head, chest and feet of adults are light brown, and the abdomen and COLEOPTERA are milky white. At first, insects were immature and unwilling to move. Coleoptera was black, hard and elastic. The second pair of wings are membranous wings, but they can't fly because of degradation and crawl quickly. After careful feeding, adult populations mate and lay eggs. Each adult lays 24 eggs, and each female lays about 300-600 eggs, which are scattered under the screen at the bottom of the feed. The adult stage is about 3090 days. The adult looks like a firefly, with a length of 10 18 mm, a width of 46 mm, and a weight of 0. 10.2g/ individual. It is divided into three parts: the chest and the abdomen, with a knot of *** 13. The head has 1 node, a pair of antennae, and the 23 nodes at the end are rod-shaped, and the mouth is born under the head. The head is small, partly embedded in the chest, with a pair of black jaws and chewing mouthparts. There are 3 thoracic segments, and there is no obvious dividing line between the back plate and the side plate of the anterior chest, and most of them are healed, and the front thoracoabdominal seam is obvious. There are *** 8 abdominal segments, 5 abdominal segments can be seen, and the tail is 1 segment. There are connectors hidden in male insects and ovipositors hidden in female insects.

Eggs: Very small. Long oval. The shortest diameter is about 0. 30. 8 mm ... The surface of an egg is an eggshell. It is filled with milky white egg-like substances. The egg period is 8 10 days. Adults lay most eggs at 25℃ and 32℃, showing milky white. The length and diameter are 0.7 1.2 mm, and the inner layer is yolk membrane. The quality is also very high. When the temperature is lower than 15℃, few people mate and lay eggs, and when the temperature is lower than 10℃, they do not mate and lay eggs.

Six, breeding Tenebrio molitor species, feed.

First, the conditions for reproduction

1) Cultivate the most important species of Tenebrio molitor. According to the technical requirements of Tenebrio molitor breeding. Eliminate pests and diseases. Each insect state reproduces synchronously, and adult larvae, pupae and adults can all be used as seed insects. Feeding insects at different stages. Carefully select pupae and adults. Sift eggs. Realize purification and rejuvenation. After buying adult larvae, feed them in a wooden tray filled with wheat bran and add fresh vegetables. Observe the pupation carefully. When pupation occurs in the tray, put the sieve tray into a wooden pallet filled with feed until the pupa emerges into an adult. In this case, you can also buy pupae, and put them together with the mature pupae two days later. Every 0.5 kg of pupae is put in a sieve tray filled with wheat bran, then put in a wooden tray filled with feed and put on a numbered shelf. When they appear, pay attention to remove the dead pupae. If you buy adults, put them in a sieve tray filled with feed, screen them out and change the tray every 7 days. The eggs are mixed in the feed under the sieve, put in the wooden pallet and continue to hatch. After careful selection and feeding, insects at all stages can be used for breeding, but it is better to use larvae as seeds and facilitate transportation.

2) Feed The main feed of Tenebrio molitor is wheat bran. Radish. Vitamins can speed up reproduction and growth, and some auxiliary feeds can also be used, such as bran, all kinds of cake cypress and straw feed. Vegetables are mainly Chinese cabbage. Ganlan and other green leafy vegetables can also be used. These feeds can meet the needs of protein. The needs of trace elements and moisture. In order to purify the regenerated population. A small amount of glucose powder and fish meal can be added to the feed. Every 0.5 kg of Tenebrio molitor can eat 1.5 kg of wheat bran and 1 kg of vegetables in a generation cycle.

3) Equipment

1. Feeding Tenebrio molitor must have a feeding room. You need to keep warm in winter. The size of the feeding room. 1 The room can support 300-500 pallets. There should be plenty of light and good ventilation. Depending on the number of Tenebrio molitor. Generally every 20 square meters.

2. wooden pallet fed with Tenebrio molitor is a drawer-type wooden pallet. The specification is 80 cm long. Eight centimeters tall. The thickness of the plate is 1.5 cm. You need to put it in a wooden tray, usually rectangular. It is 40 centimeters wide. Bottom nail fiberboard. The sieve plate is also rectangular. The length, width and height are 75 cm, 35 cm and 6 cm respectively, and the thickness of the plate is 1.5 cm. The bottom of the board is nailed with 10 mesh iron net and plywood. The wood used to make the feeding tray is preferably soft miscellaneous wood without peculiar smell. In order to prevent insects from crawling out, plastic strips should be attached to the four frames of the feeding tray. Make a wooden frame. Prevent tilting or toppling. Then you can put the feeding trays on the shelves in order.

3. According to the feeding quantity and the number of feeding plates, put the feeding plates on the wooden frame. Connect and fix the wooden frame with square wood.

4. Use iron nets with different thicknesses for egg trays and isolation nets. 12 14 16 is used to distinguish insects of different ages.

5. The temperature in the feeding room should be kept between 15-25 degrees Celsius in winter and summer. Insects don't eat or grow below 5 degrees Celsius. The ground should not be too wet. If you don't raise it in winter, you can overwinter naturally. Ventilation is needed in summer. Indoor thermometers and hygrometers should be available. Insects over 35 degrees Celsius will be burned to death. The humidity should be kept between 50-70%. Keep warm in winter.

Second, the breeding technology

1) Adult stage; The process of pupa emergence into adult is about 3-7 days. Feathers grow on the abdomen and tail. Because it is synchronized pupation. The newly emerged adult is very immature. About 5 days later, the body color became darker, and the head, chest, feet and wings emerged first. So you can complete the eclosion in a few days. Not active. The sheath wings become hard. Male and female adult populations usually mate in the dark and have a long mating time. When laying eggs, the tail of the female insect is inserted into the sieve hole to produce, and it is best not to stir at will during this period. When a layer of eggs is found attached to the bottom of the sieve tray, the sieve tray can be replaced. At this point, after screening the eggs, put the adults into another plate full of feed and take out the dead worms. Change the egg tray every four days. The survival period of adults is 60-90 days, and adults in spawning period need a lot of nutrition and water, so it is necessary to add wheat bran and vegetables in time, and fish meal can also be added. If the nutrition is insufficient, adults will bite each other and cause losses.

2) egg stage; Adults lay eggs in wooden trays filled with feed. Larvae can hatch naturally. Not suitable for turning. 1 instar worm has been born. Put the wooden tray with eggs on the shelf. Watch carefully. Prevent damage to eggs or hatching larvae. When larval skin appears on the feed surface.

3) larval stage; Eggs hatch into larvae. A tray for adults to lay eggs. When the molting body length exceeds 0.5 cm. The density should not be too large, and the period before pupation is called larval stage. After 7-9 days of incubation. Add wheat bran and fresh vegetables. Put 1 kg larvae on each wooden tray. Prevent insects from biting each other due to insufficient feed and active extrusion. As the larvae grow up, they should be divided in time. Wheat bran is the main feed and living place for larvae, so the feed should be kept at a natural temperature. In general, when the temperature is high, the larvae mostly move on the feed surface, and when the temperature is low, they crawl into the lower layer to live. The feed thickness in wooden pallet is less than 5cm. When the feed is gradually reduced, screen out the insect dung with a sieve and add new feed. 1-2 instar larvae should be screened with a 60-mesh screen to prevent the larvae from leaking out of the screen hole. First, prepare a wooden tray with new feed, and put the screened larvae into the wooden tray while sieving. The growth of Tenebrio molitor larvae needs to break through the outer skin and molt again and again before they can grow up. Larvae molts 7- 12 times, each time molts, the worm grows up, and the larva 1 year. Molting once every 8 days on average. When the larvae molt, the epidermis first splits from the back seam of the chest, and then the head, chest and feet gradually fall off. Larvae generally molt on the feed surface and enter the feed after molting. The newly molted larvae are milky white with tender and smooth skin.

4) pupation stage: larvae pupate on the feed surface. Before pupation, larvae climb to the top of feed. The pupation is completed in the final molting process. The pupation can be completed in a few seconds. The newly formed pupae are white and yellow. Abdominal peristalsis. Turn dark yellow. There are differences between larvae, and worms will slowly expand and contract when they are still. Pupa is a little longer. The pupa is getting shorter. It is shown in the order of pupation time and individual ability. The newly formed pupae and larvae live in wooden trays, and the pupae are easily bitten by larvae in the chest and abdomen, eating internal organs and becoming empty shells; Some pupae are infected by virus in the process of pupation, and become dead pupae after pupation, which needs to be checked frequently. It is found that this situation can be disinfected by spraying space with 0.3 10-6 bleaching powder solution. At the same time, the dead pupae will be picked out and disposed of in time. When picking pupae, put them in the same sieve tray with feed, adhere to synchronous reproduction, and concentrate on eclosion into adults.

Third, management measures

In the breeding process of Tenebrio molitor. It is related to the reproduction speed, worm body quality and economic benefits of Tenebrio molitor. It is very important to master farming techniques and management measures.

It is best to disinfect outside the door. Non-breeders are forbidden to enter the breeding house. People who have to enter the room. Transformation is an important link. Can master the breeding technology. In the life history of Tenebrio molitor. Grasp the time, form and characteristics of transformation in each link. Third, the feed should be fresh. Vegetables will not rot. Bran bran will not deteriorate. Every time you molt. Add a new feed. There are eggs and insect droppings at the bottom of feed in adult stage. Change dishes in time. Four larval stages. Change feed and sift manure in time. Easy to get moldy. Yes, larvae. Glucose powder, vitamin powder and fish meal are properly added to the feed. Feed fresh vegetables every day. Fifth, in order to speed up reproduction and growth. Adult after emergence. Breeders should check the situation of each insect stage every day. Prevent bacterial infection. If pests and dead insects are found, they should be removed in time. In order to ensure the success of Tenebrio molitor reproduction. The breeding of Tenebrio molitor should be carried out as planned. There should be a complete record of the number of striped worms and the number of larvae per age.
