What is the lifecycle of the cabbage seedpod weevil?
There is one generation per year. The adults over-winter in Saskatchewan and emerge in the spring migrating from weeds into host crops. They feed and mate, with the females laying eggs onto developing pods. After hatching, the larvae feed within the developing pod – consuming seeds. When mature, the larvae exit through the pod wall, dropping to the ground to pupate. Later, the emerging adults will feed on the plants causing additional damage. It takes the weevil close to eight weeks to complete development from egg hatch to adult.
