How to breed grasshoppers

1. Site selection: Grasshoppers are pests for agricultural planting, so the breeding site should be selected in an area far away from crops and fruit planting, and the sunlight should be sufficient, and the air and drainage system should be good. The breeding site should be very quiet, because grasshoppers are very afraid of people and noise. If it is noisy, they will escape or even go on a hunger strike. After selecting a good site, you need to build a breeding shed about two meters high, and disinfect the breeding shed.

2. Hatching management: The most important thing in grasshopper hatching management is temperature control. First, we need to gently place the newly purchased grasshopper eggs into the breeding shed, then choose a place with the most sunlight to level the soil, and then evenly spread the grasshopper eggs on it, cover it with fine soil, and control the temperature in the shed to around 25 to 30 degrees. At the same time, fluorescent lamps are needed for lighting, because at least twelve hours of light must be guaranteed every day. Generally, hatching will be successful in about ten to fifteen days.

3. Larvae management: The newly hatched larvae are very fragile and small. We can place some fresh corn, wheat and tender leaves in the shed until they shed their skin for the first time. The grasshoppers will slowly shed their skins in about a week. At this time, they are still not big. It takes at least three sheds to be considered a formal molt. At this time, we must ensure that there is sufficient food in the shed. One thing that needs special attention in larvae management is that you must not move them when they are molting, otherwise the mortality rate is extremely high.

4. Feed management: The cost of breeding grasshoppers is very low. For them, all green plants can be food, so their daily feed is tender grass and tender vegetable leaves, which can basically maintain their normal growth. But if you want the grasshoppers to grow faster and fatter, you can add some corn kernels, wheat, sorghum, millet, wheat straw powder and other more nutritious foods.

5. Adult management stage: It usually takes only one month for grasshoppers to transform from larvae to adults, so during this period we only need to pay attention to the temperature, moisture and feed in the breeding farm. The most important thing for adults is to mate and lay eggs, which is best done when the grasshoppers are about 15 days old. In addition, the food intake should be controlled during the egg-laying period, so that the egg-laying rate will be increased.

2. Construction of breeding shed

Grasshoppers have the habit of flying, so they must be raised in a shed. The breeding shed should be built in a ventilated and sunny place, and the ground should be 10 cm higher than the surrounding ground for drainage. It is best to use sandy loam that is not easy to clump, so as to facilitate the picking of grasshopper eggs. Monocotyledonous plants such as wheat or corn should be planted in the breeding shed for grasshoppers to eat. An area of ​​15 square meters is required for every 10,000 grasshoppers. You can use the vacant space inside and outside the yard to build the shed support with angle iron or wooden sticks, bamboo poles, bamboo strips, etc. According to the size of the shed, use a gauze to make a shed cover, bury the bottom edge quietly in the ground, and leave a door. Install a zipper at the door to prevent grasshoppers from escaping. The height of the shed is 1.5 meters to 2 meters, and the outside of the shed can be covered with plastic film to prevent rain and keep warm. The shed must be built before the end of April.

3. Breeding management

The starting temperature for grasshopper development is 15℃, the highest temperature for development is 40℃, the suitable temperature for development is 25℃～32℃, the relative humidity of air is 85%～92%, and the moisture content of soil is 15%～18%. Below 14℃ or above 40℃, wild grasshoppers will stop eating and die. Grasshopper eggs hatch when the temperature is 28℃～30℃. First, prepare non-toxic soil and sawdust and mix them in a ratio of 1:2, with a moisture content of 20%～30%. Spread 3～5 cm of soil in a container and pat it, evenly spread the grasshopper eggs on the soil, and cover with 1 cm thick mixed soil. Cover the container with a film and check it once every half a day. After finding the little grasshopper, use a soft brush to move it to the food in the shed. It will hatch in 10～15 days. The little grasshopper likes to eat fresh monocotyledonous plants such as wheat seedlings, corn seedlings, and weeds, and the food intake is very small. Grasshoppers aged 1～3 should be protected from rain. They grow to adults at 27～35 days old. During this period, it sheds its skin once every 5 to 7 days, for a total of 5 times. Each grasshopper lays 70 to 100 eggs. Grasshoppers like to live in groups and migrate. They live in groups and migrate in order to feed and reproduce and lay eggs. Therefore, grasshoppers should be given appropriate artificial interference after they emerge and before they lay eggs, so that they can migrate in the shed to increase the number and quality of eggs. The eggs laid should be covered with wheat bran, weeds, etc. to keep them warm and moist before freezing. If adult grasshoppers are not used for breeding, they must be sold in time. Beginner breeders can purchase breeding grasshoppers or eggs from farms (households). Grasshoppers are a special breed. If there are no orders and reliable sales channels, breeding must be cautious.

It is not easy to raise them. A 50-square-meter shed needs one mu of grass to raise about 30,000 groups of fish, about 300-350 per pound, and the market price is 15 to 30 yuan.
