Parasitoids of the cabbage seed weevil deliver high and consistent parasitism in variable landscapes: a showcase of conservation biocontrol.

CSW and its parasitoids respond similarly to inter-annual changes in the OSR resource; in addition, parasitoids benefit from uncropped areas in the surrounding landscape. The complexity of pest and parasitoid response to landscape factors limits the prospect of designing landscapes for improved pest control by the parasitoids. Parasitoids of CSW may be present as local populations in agricultural landscapes with the potential for consistent and substantial parasitism. This article is protected by copyright.
