Biological Control of the Cabbage Seedpod Weevil Associated with Oilseed Rape in Idaho
The cabbage seedpod weevil is a major pest of winter and spring canola. Limited insecticide choices and concerns over pollinator protection are problematic. Biological control could substaintly reduce the need for insecticides, thus protecting pollinators and reducing input costs. Larval parasitoids are present, but the species complex and intensity of parasitism is unknown. This project will determine which species are present and how they can be conserved for maximum impact against the pest.
