How to breed locusts
Question 2: locust breeding technology Shandong Zhanhua East Asia locust farm is a new enterprise integrating locust breeding, technology promotion, product recycling, processing, sales and development. After long-term practical research, we have mastered a set of breeding techniques with high incubation and high yield. The company is now developing with the business model of "technology promotion+cooperative farming by farmers". According to the spring-like climate in Kunming, our company can plant grass in four seasons and breed locusts all year round. The produced live locusts, quick-frozen locusts and dried locusts are of high quality and low price, and are favored by users. Our company is located in Feng Min Village, Guo Fu Town, Zhanhua County, Shandong Province, with superior natural climate and resource conditions. Since its establishment in 2007, our company has been an economic entity integrating locust breeding, breeding, promotion, technical training, product development and sales. Since its establishment, our products have sold well in all provinces and cities in China, turning harm into treasure. We have mastered the development and hatching management of locusts, the morphological changes of locusts at all ages, and the management before and after spawning.
Question 3: How to cultivate locusts well? Breeding technology is on the one hand, your consideration is right, and the key is marketing. If you have to wait for recycling, you are likely to be cheated. You should set up your own channel. If there is no good channel, it is recommended to breed bulk commodities. A lot of special farming died because of the channel, and my friend just lost money on the breeding EMU. As for technology, you should study hard for the simple introduction and scale. Locust is what people often say. Rich in nutrition, it is a famous dish on people's table. The investment is small, but the return is many years. The breeding cost is low and the profit is the highest. It can be said that the investment in breeding locusts will not be great. Because the locust itself has a strong reproductive ability, a locust probably lays 50-80 eggs without any disease. The cost is low, its feed is grass, just make a shed and cover a screen window. The growth period is 50 days, and the three generations in the north and south can continue to grow and reproduce. In China, eating locusts has a long history. People used to wash locusts, fry them, sprinkle them with salt and pepper and eat them. Some restaurants and hotels fry locusts to make delicious dishes such as "grasshoppers thrive" and "ground shrimp"; The deep processing of locusts can also be made into canned food, dehydrated food, frozen food, pickled food and other flavor foods. The following are the breeding techniques of locusts for reference: preliminary preparation for raising locusts: a breeding shed should be built to raise locusts. It is advisable to choose ventilated and sunny places, in front of and behind houses, and idle courtyards and plots. The ground of the breeding shed should be higher than the surrounding ground 10 cm ~ 15 cm to facilitate drainage in rainy season. Sheds can be made of bamboo chips, poles, sticks, etc. Then make a greenhouse-like shed cover with gauze, bury the bottom in the ground, and leave a door, which can be zipped or glued with tape. The shed height 1.5m ~ 2m must be completed by the end of April. The area of the shed depends on the number of locusts. Generally, 600 to 800 adults can be raised per square meter. At first 15 square meters can raise 10000 locusts. Each female locust can lay 50 ~ 80 eggs, and the greenhouse will continue to expand with the increase of locust swarms. After the breeding shed is built, plant dense wheat on the ground in the shed for small locusts to eat. Management of locusts: firstly, prepare non-toxic soil, and mix new sawdust with soil according to the ratio of 2: 1, with water content of 20% ~ 30%. Spread 3 cm ~ 5 cm thick utensils or boards, and cover the eggs with about 1 cm thick soil. After 18 days to 15 days, all locusts can hatch around May Day. After the young locust hatches, it is skinned every 7 days, and once it is skinned, it is one year old. After peeling for 5 times, it becomes an adult. In another 50 days, adults can sell (500 to 700 locusts per kilogram) or stay to lay eggs. During the period of 1 ~ 3 instars, the food intake of larvae was very small, and after 35 days, the food intake doubled. The artificially planted Mexican corn grass can be harvested and fed in addition to collecting some wild weeds. But locusts are the most harmful, especially the oriental migratory locust, so we usually talk about it. Although locusts are not big, they are powerful. The largest locust swarm can reach 250 billion. When flying, the ground shook for miles, and green things were everywhere. The diet of locusts is very diverse, and almost all green vegetation can be used as their food. They eat not only for nutrition but also for water. Greedy foraging and long-distance migration are the survival skills of locusts. When crops and other plants are scarce, they can even eat the wool on the back of sheep, the grass on the roof and the wooden handles of farm tools that smell of sweat or oil. When there is nothing to eat, they kill each other and eat their own kind. The locust's shell is extremely hard, and it is still safe when it hits a speeding car. After a full meal, locusts can digest all the food in 30 minutes. When food is scarce, they can walk for 6 days without eating or drinking. Locusts can be used: although locusts are harmful, they are not useless. For example, they are one of the main sources of edible insects. According to some data, locusts are rich in crude protein, amino acids and various bioactive substances necessary for human body, such as ATP and coenzyme Q, etc. People have long had the custom of frying or grilling locusts as delicious food with unique flavor. In Thailand, the name of "Fried Shrimp" (Fried Locust) is widely known. Romantic French also use locusts to produce high-protein food. Locusts also have high health care and medicinal value. The locusts caught in summer and autumn have the functions of relieving cough, relieving asthma, relieving convulsion, clearing away heat and toxic materials, and can be used to treat diseases such as bronchial asthma and whooping cough.

Question 4: How to breed grasshoppers 1. The value of grasshoppers.
Locust is an insect with both medicine and food, belonging to ORTHOPTERA and Acridoidea of Insecta. There are 859 species of locusts, only oriental migratory locusts and rice migratory locusts can be used as medicine. These two kinds of grasshoppers are nutritious, tender and delicious as shrimp. Grasshopper is rich in protein, carbohydrates, insect hormones and other active substances, and contains a variety of vitamins and elements such as phosphorus, calcium, iron, zinc and manganese. Grasshoppers are a good medicine for treating diseases. According to Compendium of Materia Medica, grasshoppers can be used alone or in combination to treat many diseases, such as tetanus, convulsion, fever, asthma, tracheitis, cardiovascular and cerebrovascular diseases, etc. Locusts are hermaphroditic and oviparous, and reproduce for 2 generations every year, namely summer locust and autumn locust.
Second, the construction of breeding shed
Grasshoppers have the habit of flying and must be kept in sheds. The breeding shed should be built in a ventilated and sunny place, and the ground should be higher than the surrounding ground 10 cm to facilitate drainage. It is best to use sandy loam that is not easy to agglomerate to pick up grasshopper eggs. Monocotyledonous plants such as wheat or corn are planted in the feeding shed for grasshoppers to eat. Every 10000 grasshoppers need an area of 15 square meters. You can use the free space inside and outside the courtyard to build a shed with angle iron or wooden sticks, bamboo poles and bamboo chips. According to the size of the shed, 1 shed cover is made of gauze, and the bottom edge is buried underground, leaving a door. The door was zipped to prevent the grasshopper from escaping. The height of the shed is 1.5m ~ 2m, and the outside of the shed can be covered with plastic film for rain protection and heat preservation. This shed must be built before the end of April.
Thirdly, aquaculture management.
The initial development temperature of grasshoppers is 15℃, the highest development temperature is 40℃, the suitable development temperature is 25℃ ~ 32℃, the air relative humidity is 85% ~ 92%, and the soil water content is 15% ~ 18%. When the temperature is lower than 14℃ or higher than 40℃, locusts stop eating and die. When the temperature is between 28℃ and 30℃, grasshopper eggs hatch. Firstly, non-toxic soil and sawdust are prepared and evenly mixed according to 1:2, with a water content of 20% ~ 30%. Spread 3 ~ 5 cm of soil and pat it in the container. Spread grasshopper eggs evenly on the soil and cover it with mixed soil with a thickness of 1 cm. Check the film on the container cover 1 every half day. After finding the grasshopper, use a soft brush to dial it on the food in the shed. 10 ~ 15 days to complete the incubation. Grasshoppers like to eat fresh and tender wheat seedlings, corn seedlings, weeds and other monocotyledonous plants, and their food intake is very small. 1 ~ 3-year-old grasshoppers should pay attention to rain. Adults aged 27 to 35 days. During this period, 1 molts 5 times every 5 ~ 7 days. Each grasshopper lays 70 ~ 100 eggs. Grasshoppers have the habit of living in groups and migrating, which is for foraging and spawning. Therefore, after locust emergence and before spawning, proper artificial interference should be given to make it move in the shed to improve the quantity and quality of spawning. The laid eggs should be covered with wheat bran and weeds to keep warm and moist before freezing. Adult grasshoppers should be sold in time if they are not used as seeds. Newly raised families can buy grasshoppers or eggs from farms (families). Grasshopper is a special species. If there is no order and a reliable market, farming should be cautious.
Question 5: How to breed grasshoppers? Grasshoppers, commonly known as grasshoppers, have chewing mouthparts and are herbivorous insects. Its tentacles are short whip-shaped, its hind legs are strong, and it can avoid natural enemies by bouncing. The body color is green and brown, which is the protective color of the living environment. Locusts have large mouths and developed jaws, and feed on plant leaves. Locusts like to eat reed, barnyard grass, white grass, dog tooth grass and Artemisia, shrimp grass and Salicornia bigelovii Torr. There are more than 12000 species in the world. Distributed in tropical and temperate grasslands and desert areas all over the world.
I. Selection and identification of breeding locust provenance
The methods to determine the species of locusts are:
(1) Consult an expert on locust classification.
(2) refer to the locust key table or atlas.
⑶ Consult an experienced locust farmer.
(4) Send the locust species to customers for identification and review.
Common species of cultivated locusts are: oriental migratory locust, cotton locust, Chinese rice locust, Chinese grasshopper and so on. These varieties have their own advantages and disadvantages, so it is necessary to comprehensively consider their growth cycle, algebra, taste, food, size, varieties needed by customers and other factors, and select breeding varieties in combination with local climate and food sources.
Second, the construction of locust breeding shed
The area of the shed depends on the number of locusts. Generally, about 300 adults can be raised per square meter. In order to breed migratory locusts in natural conditions, the shed construction must be completed before the end of April, because the eggs of northern locusts can usually hatch in May.
locust
Third, nymph management.
(1) Grasshoppers eat very little and like to eat fresh and tender plants. During this period, grasshoppers are very delicate, so we should pay attention to rain protection and prevent drowning.
⑵ The temperature is controlled at 25-30℃, the illumination is above 12 hours, and the humidity is kept at about 15%. Under this condition, locusts are the most active and like to eat, which is conducive to growth.
(3) The food intake of locusts over three years old is gradually increasing. At this time, it is necessary to ensure that there is enough food in the shed, otherwise it will affect its normal growth and lead to cannibalism.
(4) Keep the shed clean and clean it every 1-2 days to prevent diseases.
4. Locust is a disastrous insect, which is different from other special aquaculture. Breeding it can turn harm into treasure and increase farmers' income, on the other hand, it can increase the number of locusts and form potential harm. It is necessary to take necessary safety management measures for its breeding in order to achieve twice the result with half the effort. For large-scale farming, according to the standard of 1 mu, a plant infection isolation belt with a width of half a meter should be built around the farm, surrounded by barbed wire fences and pesticide sprayers. There are many kinds of pesticides that kill locusts, and 75% malathion EC or 2.5% pyrethroid can kill them.
If farmers don't want to breed locusts, they should take the last extermination measures. Farmers don't want to breed, so they should make preparations in advance. They can't dismantle the anti-breeding shed before May 20th every spring. After all the locusts are unearthed, they should be killed with pesticides before the adults, so there will be no harm. Before the end of autumn, farmers decided not to breed any more. They must sell all the locusts or kill them with pesticides before September 10, that is, before they mate, and they are not allowed to lay eggs in the breeding shed. This measure can ensure the elimination of potential hazards in the future and is conducive to the healthy development of locust breeding industry.
Question 6: How to raise locusts? Locust breeding method:
1. Construction of locust breeding shed and layout of shed land
Before building a shed, ants and crickets on the ground should be killed by catching, trapping and scalding. These animals are natural enemies of locusts, which can prey on locusts and destroy their eggs, so these animals must not exist in the shed. The ground of the shed is higher than the surrounding ground 10 ~ 15 cm. It is best to use sandy loam, which is not easy to agglomerate and is convenient for laying eggs and taking eggs. Monocotyledon crops such as wheat are planted on the ground where the shed is built for locust larvae to eat. The construction area of the shed depends on the number of locusts to be raised, 10000, 15 square meters. According to your own conditions, you can use the free space inside and outside the hospital to build a scaffolding with iron, sticks and bamboo pieces. Then according to the size of the scaffold, make a mosquito net-like shed cover with cold cloth, hang it on the scaffold, bury the bottom edge underground, and leave the door. Zip the door. This device is designed to prevent locusts from running out and facilitate feeding and management in the house. Shed height 1.5 ~ 2m. In order to keep warm or rain-proof, plastic sheets can be covered outside the shed. The temperature is high, the locusts are old (over 3 years old), and they are not afraid of rain, so they don't need to cover with plastic sheets. Those who use natural conditions to breed migratory locusts must complete shed construction before the end of April. You should choose a sunny place.
2. Hatching and management of migratory locust eggs.
When the temperature reaches 25 ~ 30℃ (early May), it can hatch. Firstly, non-toxic soil and sawdust (according to the ratio of 2: 1, the water content is 10% ~ 15%) are prepared and laid in a container of 2 ~ 3 cm. After that, the locust eggs were evenly spread on the soil, and the eggs were covered with soil about 1 cm thick, and the container was covered with a film. Check it every half day. When young locusts are found, put them on the food in the shed with a soft brush. After 12 ~ 15 days of incubation, all the young locusts hatched. Young locusts like to eat fresh and tender wheat seedlings, corn seedlings, weeds and other monocotyledons, but they eat very little. 1 ~ 3-year-old young locusts should pay attention to rain protection. The temperature should be controlled at 25 ~ 30℃, the light should be above 12 hours, and the humidity should be kept at about 15%, because locusts are the most active and like to eat, which is conducive to growth. Locusts like to live in groups.
Feeding management of adults over 3.3 years old.
Young locusts molt once every 5-7 days after laying eggs, and molt once is one year old. The strong ones peel fast, and the weak ones peel slowly, and they are unearthed in the process of hatching. Over 3 years old, flying fast, eating more and more. At this time, we must ensure that there is enough food in the shed. In addition, there will be a phenomenon of strong eating and weak eating, especially the locusts that are peeling can't move, and their constitution is very soft, which is in danger of being eaten and bitten. Grasshoppers over 3 years old can be fed wheat bran. /kloc-clean the shed once every 0/~ 2 days and keep it clean. After peeling for five times, the locust grows into an adult, which is about June 15. Locusta migratoria manilensis generally enters sexual maturity and begins mating on 10 ~ 15 days after emergence. At this time, migratory locusts are very fat. Except for some locusts that lay eggs, other locusts can be sold in the market, and the time is appropriate in early July.
4. Management of migratory locust before and after spawning
After mating, the abdomen of the female locust gradually becomes thicker and longer, and the yellow-brown color deepens, while the male locust appears bright yellow. At this time, the ground in the shed should be neat and solid, so as to facilitate the mother locust to lay eggs. If the shed is large and there are few migratory locusts, in order to concentrate on laying eggs and facilitate taking eggs later, part of the ground in the shed can be covered with plastic sheets, leaving only a part of the ground in the sunny place as the spawning area. The relative humidity in the shed is about 65438 05%. At this time, locusts eat a lot, so be careful to supply them. Female locusts began to lay eggs around June 10. The ovipositor of the female locust is short and curved, and it is two pairs of hard chisel-shaped ovipositor petals, which penetrate the soil to lay eggs. When laying eggs, colloidal liquid is secreted, and after solidification, a waterproof protective layer is formed outside the eggs to synthesize egg blocks, which plays a protective role in the overwintering of eggs.
The egg mass of locusts is brown, slightly cylindrical, slightly curved in the middle, generally 40 ~ 70 mm long. Each locust egg is mostly 35 ~ 90, and a few eggs exceed 100. This is summer locust. Locust eggs are produced in the soil in the shed, and the eggs used to hatch the second generation of autumn locusts can stand still in the shed. When the temperature, humidity and light reached the incubation conditions, the second generation autumn locust was naturally unearthed from July 20 to 25. The second-generation locust eggs that are ready to be sold or not used for the time being should be taken out in time, bagged with soil with the humidity of 10% ~ 15%, put in a large jar with the last layer of soil, seal the bottle mouth and store in a refrigerator at 5℃. The feeding conditions and methods before and after spawning are basically the same as those of locusts over 3 years old, but the difference is that the sunlight should reach 16 hours, the feed should be sufficient, and more concentrated feed should be added.

Question 7: Techniques of raising grasshoppers, raising grasshoppers and grasshopper breeding, how to raise grasshoppers and grasshopper breeding, and how to raise grasshoppers. If you want to raise grasshoppers and locusts, it is a new thing. There must be a solid net cover, so be careful to bite into the hole to escape. Grasshoppers and locusts like to eat tender plants, such as green wheat, corn, sorghum, ryegrass, alfalfa, leaves and natural grass. Eggs like to be born in the soil. I like the high temperature of 28 to 33 degrees. Morning 10, eat at 4 pm. Hibernate in winter, 3 ~ 5℃, with a certain humidity. Out-of-season breeding temperature and humidity should meet the standards.
Question 8: How to raise grasshoppers at home? Family rearing of locusts
1, site selection
It is advisable to choose a ventilated and sunny place.
Step 2 eliminate natural enemies
Before nesting, ants and crickets on the ground should be eliminated by trapping, trapping and scalding. Because these animals are natural enemies of locusts, they can prey on locusts and destroy their eggs, so they must not be allowed to exist in the shed.
3, the ground
The ground of the Bird's Nest is 10- 15 cm higher than the surrounding ground, so as to facilitate drainage in rainy season. It is best to use sandy loam, which is not easy to agglomerate, easy to lay eggs and take eggs, and the load should not be too soft, so locusts have high requirements for laying eggs.
4. Density
The area of the shed depends on the number of locusts, and generally 600-800 adults can be raised per square meter.
Step 5 build a nest
According to your own conditions, you can build scaffolding with wooden sticks and bamboo pieces. Then according to the size of the scaffold, make a awning like a mosquito net with gauze, hang it on the scaffold, bury the bottom edge in the ground, leave the door and press the zipper on the door. This installation is to prevent locusts from running out and facilitate the feeding and management in the shed. The shed height is only1.5-2m. In order to keep warm or rain-proof, plastic sheets can be covered outside the shed. The temperature is high, the locusts are old (over three years old), and they are not afraid of rain, so they can be covered without plastic sheets. Those who use natural conditions to breed migratory locusts must complete shed construction before the end of April.
6. There should be higher plants such as corn isolated in the shed.
The reproduction of locusts and grasshoppers
Development, Hatching and Management of Locust Eggs
The initial temperature range of locust development is 20-42 degrees, the suitable development temperature is 25-40 degrees, and the optimum temperature is 28-35 degrees. When the relative humidity is 85%-92% or the soil water content is 15- 18%, the suitable development temperature is 25-32 degrees, and the natural temperature in northern China will reach in early May. After buying the eggs, put the locust eggs directly in the soil and let them hatch naturally. After 10- 15 days of incubation, all the locusts hatched. Locusts eat less and are weak, so they should be protected from rain.
Question 9: How to raise grasshoppers artificially has a good prospect, mainly to find a good market.
Question 10: Introduction to locust breeding. Locust breeding was published by China Agricultural Publishing House. The writer is Liu Yusheng. This book introduces the equipment and facilities, seed selection, feed source and application, key breeding technologies, storage and processing technologies and comprehensive application knowledge of locust breeding.
