Pea weevil is a monophagic pest, which only harms peas. Adults feed on petals, pollen and nectar, and larvae mainly harm beans.

The pea weevil has a strong ability to spread harm. After hatching, the eggs burrow into the pod and the larvae feed in the pod. After the peas are harvested, they are taken into the warehouse together with the winter beans.

Fumigation control:

Before the peas are harvested and put into storage, when the adults have not emerged, use 2 pieces of aluminum phosphide per 100 kg of peas at 15 room temperature. Sealed at 30℃ for 3? After 5 days, the insecticidal effect reached 100%, and the use of food and seeds was not affected after sufficient ventilation.

Control of flowering and pod setting period;

When pea blooms into 1 tender pod, a large number of pea elephants concentrate on the flower pod to lay eggs. At this time, chemical control should be carried out in time to eliminate larvae and eggs.

It can be controlled by spraying efficient pesticides such as Regent and Kuaishaling. Spraying interval 5? 6 days, continuous prevention twice can achieve good results.
