(1) Locusts. Locust not only sucks peanut juice, but it is also the main medium for spreading the virus. Prevention of peanut aphid must be based on early words, when each pier reaches 10, with 40% omethoate control 1000 times.
(2) Tigers and earthworms. Tigers and earthworms are underground pests, which not only have a long duration of damage but also cause serious damage.
