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.
