CATDOLL : CATDOLL: What are the key points of greenhouse grasshopper breeding technology?

1. 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.

2. How to control the temperature when hatching grasshoppers?

Grasshoppers are locusts. The most important thing in greenhouse hatching and management of grasshopper hatching is temperature control. First, the grasshopper eggs are gently placed in the breeding shed, and then a place with the most sunshine is selected to level the soil, and then the grasshopper eggs are evenly spread on it, covered with fine soil, and the temperature in the shed is controlled at about 25 to 30 degrees. At the same time, fluorescent lamps are needed for lighting, because at least twelve hours of light are required every day. Generally, the hatching is successful in about ten to fifteen days.

Hatching of seed eggs: Grasshopper eggs are very small and have thin shells. They should be handled with care during the hatching process. Once they are broken, the hatching rate will be affected. The newly introduced seed eggs should be hatched in time. The specific method is: first find a place with the most sunshine in the greenhouse where grasshoppers are raised, rake the soil finely, then evenly spread the seed eggs on it, and then cover it with fine soil for 1 cm. At this time, the soil moisture content should be maintained between 20% and 30%. If the temperature in the greenhouse is between 28℃ and 33℃, the seed eggs can be hatched in 10 to 15 days. If the temperature of soil and manure fermentation is used to hatch the seed eggs, the effect will be better.

3. 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.
