1, there is no difference between locusts and grasshoppers, they are all the same animal, and they are mainly divided into two kinds: locusts and earthworms. Locusta migratoria manilensis is the most widely distributed in China, and it is also the main pest causing locust plague. Grasshoppers, commonly known as "grasshoppers", belong to Orthoptera, including Tetrigoidea, Acridoidea and Acridoidea. There are more than 1000 species in China, which are distributed in tropical and temperate grasslands and desert areas all over the world.

2. Locusta migratoria manilensis has diverse feeding habits, and likes weeds such as reeds, barnyard grass and red grass best. Wheat, corn, sorghum, rice, millet, sugarcane, etc. I also like to eat among the crops I grow. When food shortage occurs, it will also damage crops such as cotton, soybeans and vegetables. Locusta migratoria manilensis feeds on all green parts on the ground of plants, such as leaves, tender stems and young spikes.

3. The pre-oviposition period of adults is long, generally 10-30 days. They mate many times and lay eggs in batches. 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.
