1, the early preparation for raising grasshoppers needs to build a breeding shed. It is advisable to choose ventilated and sunny places, such as in front of the house, behind the house, idle courtyards and plots. The ground of the breeding shed should be higher than the surrounding ground 10- 15cm to facilitate drainage in rainy season. Sheds can be made of bamboo chips, poles, sticks, etc. And then use gauze to make a shed cover like a greenhouse. The bottom of the shed is buried underground, leaving a doorway with a zipper or adhesive tape. The shed height is1.5-2m, which must be built by the end of April.

The area of the shed depends on the number of grasshoppers. Generally, 600-800 adults can be raised per square meter. At first, 1 5m2 was enough to feed110,000 locusts, and each female locust could lay 60-90 eggs. With the increase in the number of locusts, the greenhouse will continue to expand. After the breeding shed is built, plant dense wheat on the ground in the shed for small locusts to eat.
