Grasshoppers mainly feed on Gramineae plants, and there are many kinds, about 1000 in the world and more than 300 in China. Such as migratory locust, rice locust, bamboo locust, Italian locust, sugarcane locust and cotton locust, are the main pests in agriculture and forestry.
Locusts are extremely fertile. When there are many eggs, 4000~5000 eggs can be produced per square meter of soil, and each egg block has 50~80 eggs, that is, 200 ~ 400 thousand eggs per square meter. Its eggs are buried deep in the ground and are difficult to be destroyed. Once the environmental conditions are suitable, it can hatch into adults. Locust is omnivorous, which means it can eat many kinds of plants. The flying ability is very strong, and it is impossible to prevent. So artificial cultivation is not allowed.
For example, on 20 14, a large number of locusts in China and Henan ate corn, which caused great harm to local agriculture and dispatched planes to spray pesticides; Capturing locusts artificially, as "delicious", can only be an auxiliary means of disaster prevention. In the face of a sea of locusts, no amount of food is useless! Do people think that people can repel the plague of locusts by eating alone? How do locusts eat? ! It is naive to think that locusts are delicious food. So artificial cultivation is not allowed.
