CATDOLL : CATDOLL: How to breed East Asian migratory locusts

How to breed East Asian migratory locust

1. Do a good job of preparation before building the shed

1. Terrain requirements: The terrain for building the shed must be high, with smooth drainage and appropriate light to prevent excessive summer rain from soaking the breeding eggs in the low-lying terrain and causing unnecessary losses.

2. Ground treatment: Before building the shed, carry out comprehensive prevention and control of underground pests (such as mole crickets, spiders, ants, etc.) to prevent such pests from growing and breeding in the shed. Prevention and control methods: Mole crickets can be caught manually by combining light illumination with large-scale horizontal irrigation. Ants can be controlled chemically by using a disposable syringe to absorb methyl parathion and dichlorvos diluted solution and inject it into the ant hole.

2. Materials and methods for building a shed

1. Materials needed to build a shed: bamboo poles, bamboo strips, wooden sticks, gauze, zippers, etc.

2. Shed construction method: It is recommended to build an arched shed, which has strong wind resistance and simple structure. The scale should be adapted to local conditions. The length of the shed is generally not more than 15 meters, the width is not more than 5 meters, and the height is 1.8 meters, so as to facilitate feeding grass, cleaning the shed, catching adult locusts, etc. Use two 4-meter bamboo pieces to make an arch with a one-meter interval and extend them in sequence, then connect them with sticks, bamboo poles and other materials, and then cover them with gauze. Dig a 15 cm deep and 10 cm wide side ditch at the edge that contacts the ground, tighten the gauze, bury it deep and step on it firmly. Leave a door at one end of the shed and seal it with a zipper or adhesive strip.

3. Preparation before egg breeding

1. Planting forage grass is arranged in early March every year. High-yield forage grass mainly includes ryegrass, Russian corn, etc. As long as the soil is fertile and water is good, this kind of grass seedlings can generally be harvested 5-6 times, and each crop can harvest about 10,000 catties of fresh grass per mu. The planning and construction is carried out according to the reasonable ratio of planting 3 mu of grass for every 1 mu of shed.

2. Wheat seedlings can also be planted in the greenhouse: first level the ridges, water the soil, turn the soil and level it, densely sprinkle wheat seeds (local wheat seeds are fine), and then cover it with 3-5 cm thick loose soil with appropriate moisture. You can also plant corn seedlings and other fodder in idle plots to prepare for young locusts to eat.

3. Incubate the eggs according to the technical instructions: the suitable temperature is 25-30℃. After all the young locusts are hatched, management must be strengthened, observation must be diligent, and damaged areas must be dealt with in a timely manner to prevent the young locusts from escaping and causing unnecessary losses.

IV. Integrated management of the East Asian migratory locust

1. Only by being diligent can you ensure successful breeding: frequent feeding, frequent observation, and frequent cleaning (remove spoiled grasshoppers in time). Keep the shed clean and sanitary, with appropriate moisture, and immediately catch the locusts that escape, and carry out normal breeding management according to technical essentials.

2. Feeding and management of summer locusts: In daily feeding, sufficient forage must be maintained. Before feeding, the forage should be rinsed with clean water one to three times to increase the moisture content of the forage and to clean the impurities and pesticide residues in the forage. When the temperature is above 32°C, pay attention to covering the shed and spraying water to cool down, and clean the shed in time to prevent locusts from eating moldy and spoiled forage, which will cause mold infection and cause losses.

3. Feeding and management of autumn locusts: Like summer locusts, autumn locusts should be protected from rainy weather, covered and rainproof, cleaned in time, and kept dry and humid. Protection should be provided in time on windy days to prevent damage caused by cracking of gauze or floating of edges. There should be sufficient forage in the late stage of autumn locusts, and attention should be paid to heat preservation to extend the feeding cycle. In the open-air mode, 2-3 batches can be raised in North China each year.

4. How to ensure the safety of locust eggs overwintering: After the adult locusts are sold, the weeds and feces in the shed must be cleaned up, and then the pests in the shed must be eliminated to prevent mole crickets, ants, etc. from stealing locust eggs. When the temperature drops below 0℃, the seed source can be covered with wheat bran, weeds, leaves, etc. for about 10 cm. This can ensure the normal development of the eggs and safe overwintering.

Please be reminded that you should introduce new species from regular professional units, and do not introduce new species blindly in order to save money. Doing so will result in low hatching survival rate, small insect body and other losses, and unstable prices, which will directly affect production and reduce income.

Just for reference, use your own discretion.

If there is no habit of eating emperor worms in your area, please do not raise them.

How to raise grasshoppers for fun

1. Grasshoppers die within a year. As the saying goes, grasshoppers in autumn will not be able to jump for a few days.

2. Grasshoppers eat the stems and leaves of crops.

3. The grasshoppers only need to eat food that contains moisture.

4. Grasshoppers need protective coloration.

5. Grasshoppers need to mate.

6. Grasshopper feces are granular, brown or black.

7. The distance between the cages should be smaller than the width of the grasshopper's body.

It is not recommended to raise grasshoppers, it is very dirty.
