CATDOLL : CATDOLL: Locust breeding methods and techniques (Locust breeding methods and techniques video)

1. New technology for locust breeding?

When raising locusts, a breeding shed should be built in a ventilated and sunny location. Wooden sticks and bamboo poles can be used as supports in the shed, and a layer of gauze should be covered on top to prevent the locusts from escaping. Then a substrate mixed with locust eggs and harmless soil should be evenly spread on the ground in the shed. After waiting for the locusts to hatch, they can be provided with feed such as wheat.

Locust breeding method:

1. Construction of locust breeding shed and preparation of shed land

Before building the shed, first use methods such as capture, trapping, and burning to eliminate all ants and mole crickets on the ground. These animals are natural enemies of locusts and can prey on locusts and destroy locust eggs, so these animals must not be allowed to exist in the shed. The floor of the shed should be 10 to 15 cm higher than the surrounding ground. Sandy loam is the best soil, which is not easy to clump and is convenient for laying eggs and taking eggs. Plant single-leaf crops such as wheat on the ground where the shed is built to prepare food for young locusts. The construction area of ​​the shed should be determined according to the number of locusts to be raised. If you raise 10,000 locusts, you only need 15 square meters. You can use the vacant space inside and outside the yard. According to your own conditions, you can use iron, big sticks, and bamboo strips to build a shed support. Then, according to the size of the shed, use cold cloth to make a shed cover like a mosquito net, hang it on the shed, bury the bottom edge in the ground, and leave a door. Install a zipper on the door. This device is to prevent locusts from running out and to facilitate feeding and management in the shed. The height of the shed can be 1.5 to 2 meters. In order to keep warm or prevent rain, plastic sheets can be placed outside the shed. When the temperature is high and the locusts are large (over 3 years old) and are not afraid of rain, plastic sheets can be omitted. If natural conditions are used to breed migratory locusts, the construction of the shed must be completed before the end of April. It is best to choose a place with plenty of sunlight.

2. Hatching and management of locust eggs

When the temperature reaches 25-30℃ (early May), it can be hatched. First, prepare non-toxic soil and sawdust (at a ratio of 2:1, with a water content of 10%-15%), and spread them in a 2-3 cm container. After that, spread the locust eggs evenly on the soil, cover the eggs with about 1 cm thick soil, and then put a film on the container. Check every half a day, and after finding the young locusts, use a soft brush to move the young locusts to the food in the shed. After 12-15 days of incubation, all the young locusts are hatched. Young locusts like to eat fresh monocotyledonous plants such as wheat seedlings, corn seedlings, and weeds, but they eat very little. Young locusts from 1 to 3 years old should be protected from rain. The temperature should be controlled at 25-30℃, the light should be more than 12 hours, and the humidity should be kept at about 15%, because under such conditions, locusts are most active, like to eat, and are conducive to growth. Migratory locusts like to live in groups.

3. Feeding and management of insects from the third instar to adults

Young locusts shed their skin every 5 to 7 days after laying eggs, and each shed is one age. Strong ones shed quickly, weak ones shed slowly, and there are also differences in the order of emergence during the hatching process. Those over 3 years old fly very fast, and their appetite gradually increases. At this time, it is necessary to ensure that there is sufficient food in the shed. In addition, there will be a phenomenon of strong eating weak and big eating small, especially the locusts that are molting and cannot move. Their physique is very soft, and there is a risk of being eaten and bitten. Locusts over 3 years old can be fed with wheat bran. Clean the shed once every 1 to 2 days to keep the shed clean. After 5 molting, the locusts grow into adults, which is around June 15. Migratory locusts generally enter sexual maturity 10 to 15 days after emergence and begin to mate. At this time, the migratory locusts are very fat and strong. Except for some locusts that lay eggs, the other locusts can be sold in the market, preferably in early July.

4. Management before and after locust laying eggs

After mating, the abdomen of female locusts gradually becomes thicker and longer, and the yellow-brown color deepens, while that of male locusts is bright yellow. At this time, the ground of the shed should be neatly tamped to facilitate the female locusts to lay eggs. If there are few large migratory locusts in the shed, in order to concentrate the eggs and facilitate the egg collection in the future, part of the ground in the shed can be covered with plastic cloth, leaving only part of the ground in the sunny area as the egg-laying area. The relative humidity in the shed is maintained at about 15%. At this time, the locusts have a large appetite and should be carefully provided. Female locusts begin to lay eggs around July 10. The ovipositor of female locusts is short and curved, with two pairs of hard chisel-shaped ovipositors, which are used to drill holes in the soil to lay eggs. While laying eggs, a gelatinous liquid is secreted, which forms a water-resistant protective layer outside the eggs after solidification, surrounding the eggs into an egg mass, which protects the eggs from wintering.

The egg mass of locusts is brown, slightly cylindrical, slightly curved in the middle, and generally 40 to 70 mm long. Each locust egg has 35 to 90 eggs, and a few have more than 100 eggs. This is a summer locust. The eggs are laid in the soil in the shed and used to hatch the eggs of the second generation of "autumn locusts". They can be left untouched in the shed. When the temperature, humidity, light and other conditions meet the hatching conditions, the second generation of autumn locusts will naturally emerge from the ground, which will be between July 20 and 25. The eggs that are ready for sale or not used for the second generation should be taken out in time, and the soil with a humidity of 10% to 15% should be used. The eggs should be placed in a large canning bottle, the bottle mouth should be sealed, and stored in a refrigerator at 5°C. The feeding conditions before and after egg laying are basically the same as those for locusts over 3 years old. The difference is that the light should reach 16 hours a day, the feed should be sufficient and more concentrated feed should be added.

5. Wintering management of locust eggs

The overwintering of locust eggs is very simple. The eggs in the shed can be left to overwinter in situ. After winter, the locust egg-laying area can be covered with some weeds to keep warm.

6. Locusts’ food preferences and natural enemies

①. Locusts feed on a wide range of food, just like feeding sheep. They like to eat: reeds, thatch, wolfsbane, thread grass, coil grass, etc. Corn, wheat, sorghum, millet, etc. of the Gramineae family are plants that locusts do not like to eat.

② When collecting food for locusts, be careful not to use food with pesticides. If you are not sure about the food you collected, you can wash it in water before feeding it.

In addition, it is important to note and remind that novice breeders can purchase seeds from farms or breeders, and can introduce either grasshoppers or eggs.

3. How to breed yellow locusts?

1. Site selection: Choose a place with good ventilation and plenty of sunshine.

2. Eliminate natural enemies: Before building the shed, use methods such as capturing, trapping, and scalding to eliminate all ants, mole crickets, etc. on the ground. Because the above animals are the natural enemies of yellow locusts, they can prey on locusts and destroy locust eggs, so these animals must not be allowed to exist in the shed.

3. Ground: The ground of the shed should be 10-15 cm higher than the surrounding ground to facilitate drainage in the rainy season. Sandy loam is the best soil, which is not easy to clump and is convenient for laying eggs and collecting eggs. It should not be too soft, as locusts have high requirements for laying eggs.

4. Density: The area of ​​the shed depends on the number of yellow locusts. Generally, 600-800 adults can be raised per square meter.

5. Build a shed: According to your own conditions, you can use wooden sticks and bamboo strips to build a shed support.

4. Grasshopper breeding technology?

To raise locusts, you need to build a breeding shed. It is best to choose a well-ventilated and sunny place, such as in front of or behind the house, in an idle courtyard or plot of land. The floor of the breeding shed should be 10 to 15 centimeters higher than the surrounding ground to facilitate drainage in the rainy season. The shed can be built with bamboo strips, bamboo poles, and wooden sticks as supports, and then use gauze to make a greenhouse-like shed cover, bury the bottom edge in the ground, leaving a door, and install a zipper on the door or stick it with adhesive strips. The height of the shed is 1.5 to 2 meters, and it must be built by the end of April.

The area of ​​the shed depends on the number of locusts. Generally, 600 to 800 adult locusts can be raised per square meter. At the beginning, 15 square meters are enough to raise 10,000 locusts. Each female locust can lay 50 to 80 eggs. As the number of locusts increases, the shed will continue to be expanded.

After the breeding greenhouse is built, wheat is planted densely on the ground inside the greenhouse to prepare for the young locusts to eat. Locust management: First prepare non-toxic soil, mix new sawdust and soil at a ratio of 2:1, with a water content of 20% to 30%, spread 3 cm to 5 cm thick on the utensils or wooden boards, and cover the eggs with about 1 cm thick soil. After 10 to 15 days of incubation, all locusts will be hatched around May Day.

After hatching, the young locusts shed their skin once every seven days, and each sheds its skin once for one instar. After 5 sheds, they become adults. After another 50 days, the adults can be sold (500 to 700 locusts per kilogram) or kept for breeding and laying eggs. During the first to third instars, the larvae eat very little food. After 35 days of becoming adults, their food intake doubles. In addition to collecting some wild weeds for feeding, they can also cut artificially grown Mexican corn grass for feeding.

5. What are the locust breeding techniques and the best time for breeding?

Locust breeding time in the north is from February to mid-October of the lunar calendar, and breeding can be carried out all year round in the south. Breeding technology: 1. Construction of locust breeding shed and preparation of shed land Before building the shed, first eliminate the ants and mole crickets on the ground by catching, trapping, burning with fire and other methods. The above animals are natural enemies of locusts and can prey on locusts and destroy locust eggs, so these animals must not be allowed to exist in the shed. The ground of the shed should be 10 to 15 cm higher than the surrounding ground to facilitate drainage in the rainy season. Sandy loam is the best soil, which is not easy to clump and is convenient for laying eggs and taking eggs. Single-leaf crops such as wheat are planted on the ground of the shed to prepare for young locusts to eat. The construction area of ​​the shed should be determined according to the number of locusts raised. If you raise 10,000 locusts, you only need 15 square meters. You can use the vacant space inside and outside the yard. According to your own conditions, you can use iron, big sticks, and bamboo strips to build a shed support. According to the size of the shed, use cold cloth to make a shed cover like a mosquito net, hang it on the shed, bury the bottom edge in the ground, leave a door, and install a zipper on the door. This device is to prevent locusts from running out and facilitate feeding and management in the shed. The height of the shed can be 1.5 to 2 meters. In order to keep warm or prevent rain, plastic cloth can be covered outside the shed. When the temperature is high and the locusts are large (more than three years old), they are not afraid of rain, so plastic cloth can be omitted. If natural conditions are used to breed migratory locusts, the construction of the shed must be completed before the end of April. It is advisable to choose a sunny place. 2. Hatching and management of migratory locust eggs When the temperature reaches 25 to 30℃, they can hatch, and the natural temperature will reach in early May. First prepare non-toxic soil, sawdust 2:1, water content 10 to 15%, spread in a 2 to 3 cm container, spread the locust eggs evenly on the soil, cover the eggs with about 1 cm thick soil, and then put a film on the container. Check once every half a day. When young locusts are found, use a soft brush to push them onto the food in the shed. After 12 to 15 days of incubation, all young locusts are hatched. Young locusts like to eat fresh and tender wheat seedlings, corn seedlings, weeds and other monocots, but they eat very little. Young locusts from 1 to 3 years old should be protected from rain. The temperature should be controlled between 25 and 30 degrees Celsius, with more than 12 hours of light and humidity maintained at about 15%, because under such conditions, locusts are most active, like to eat, and are conducive to growth. Migratory locusts within the third instar like to live in groups. 3. Feeding and management of young locusts from the third instar to adults Young locusts shed their skin once every 5 to 7 days after laying eggs. Each shed is one instar. The strong ones shed quickly, while the weak ones shed slowly. There is also a difference in the order of emergence during the incubation process. Those above the third instar fly particularly fast and their food intake gradually increases. At this time, it is necessary to ensure that there is sufficient food in the shed. First of all, if the locusts are not full, it will affect their normal growth. In addition, there will be a phenomenon that the strong eat the weak and the big eat the small, especially the locusts that are molting cannot move, and their physique is very soft, so there is a risk of being eaten and bitten. Wheat bran can be added to locusts above the third instar. Clean the shed once every 1 to 2 days to keep the shed clean. After the locusts molt five times, they grow into adults, which is about June 15. Migratory locusts generally enter sexual maturity 10 to 15 days after emergence and begin to mate. At this time, the migratory locusts are very fat and strong. Except for some locusts that lay eggs, the other locusts can be sold in the market. The time is preferably in early July. 4. Management before and after migratory locusts lay eggs After mating, the abdomen of female locusts gradually becomes thick and long, and the yellow-brown color deepens, while male locusts appear bright yellow. At this time, the ground of the shed should be neat and compacted to facilitate the laying of eggs by female locusts. If there are few large migratory locusts in the shed, in order to concentrate the eggs and facilitate the egg collection in the future, part of the ground in the shed can be covered with plastic cloth, leaving only part of the ground in the sunny area as the laying area. The humidity in the shed is kept at about 15%. At this time, locusts have a large appetite and should be fed with enough food. Female locusts begin to lay eggs around July 10. The ovipositor of female locusts is short and curved, with two pairs of hard chisel-shaped ovipositors, which are used to drill holes in the soil to lay eggs. While laying eggs, a gelatinous liquid is secreted, which forms a water-resistant protective layer outside the eggs after solidification, surrounding the eggs into an egg mass, which protects the eggs during the winter. 5. Overwintering management of locust eggs Overwintering of locust eggs is very simple. The locust eggs in the shed can be left to overwinter in situ. After winter, some weeds are added to the locust egg-laying area to keep them warm.

6. How to raise yellow grasshoppers?

Breeding methods

1. Site selection

Yellow grasshoppers are very strong, so it is easy to choose a breeding site, but it is best to be away from crop planting areas. They are very timid and will run away or even go on a hunger strike when disturbed. Therefore, places near roads should not be used as breeding sites.

2. Incubation management

Gently scatter the yellow grasshopper eggs on the ground, and then cover them with fine soil. The temperature in the breeding greenhouse should be kept between 25-30 degrees. At the same time, fluorescent lamps should be used, and the lighting time should be kept at 12 hours a day. In this way, the eggs will hatch after 2 weeks.

3. Feed management

Yellow grasshoppers need to be fed with grass. If conditions permit, you can grow grass yourself. Generally speaking, to raise one acre of locusts, you need to plant two acres of grass. You can choose Mexican corn grass, sorghum, etc. If you want the locusts to grow fast and fat, you also need to use corn, wheat, sorghum and other grain feed.

4. Adult management

It takes 4 weeks for yellow grasshoppers to grow from larvae to adults. After that, they will mate and lay eggs. And during the egg-laying period, you should control your food intake, so that the egg-laying rate will be increased.
