There are more than 0/000 species of locusts/kloc-in China, of which about 60 species can cause harm to agriculture, forestry and animal husbandry. The species that harm crops such as beans, potatoes and sweet potatoes are short-winged locusts and benzene locusts. Both cotton locust and negative locust can harm cotton. Bamboo locust will seriously harm bamboo forest.
When it happens, it will seriously harm pasture and crops and directly affect the development of agriculture and animal husbandry. According to thousands of years' historical records in China, the locusts that caused devastating disasters in agriculture were mainly migratory locusts, and it was considered that the probability or correlation between drought and migratory locusts in that year was the greatest, followed by drought in the previous year, waterlogging before drought and grasshoppers in patches.

1, the harm of feeding habits and feeding methods
Adults and grasshoppers have the same feeding habits, both of which are phytophagous, and the supplementary nutrition in the adult stage is vigorous, accounting for more than 75% of the total food intake in a lifetime. They use chewing mouthparts to bite the leaves and buds of plants into notches and holes, and in severe cases, they will eat large areas of leaves and buds of plants, causing huge economic losses to agriculture, forestry and animal husbandry.
2. Activity habits
Adults and locusts lie down at night and come out during the day, so they have no obvious phototaxis.
When the density of migratory locusts is high, conditioned reflex is formed due to mutual feeling, which intensifies the activity. Locusts can easily form groups, rest and crowd, and then jump in a certain direction.
