Plant diversity in agroecosystems
More efficient control of pests and diseases but not always
(Bone et al. 2009, Danne et al. 2009, Ratnadass et al. 2012)
3x higher squash bee density in no‐tillage squash and pumpkin farms than in tilled farms(Shuler et al. 2005)

Adaptive management can be applied at the farm‐level scale to improve populations of beneficial insects to improve crop yields and reduce pest damage
More research is needed on the responses of beneficial insects to different cover cropping practices
