Cover Crops and Conservation Biocontrol: Can the Impacts of Trichogramma (Hymenoptera: Trichogrammatidae) Be Magnified?

The combination of a primary target crop with flowering plants as cover crops or as a way to diversify the cropping system may provide many benefits, including enhancing conservation biological control by natural enemies of pests that can be attracted to the resources provided (Landis et al. 2000, Bickerton and Hamilton 2012).
