Data for Coco et al. 2022 Oecologia, More phylogenetically diverse polycultures inconsistently suppress insect herbivore populations

A.M. Coco, E.C. Yip, I. Kaplan & J.F. Tooker
Because the diet of many herbivorous insects is restricted to closely related taxa with similar chemistry, intercropping with diverse plant communities may reduce both pest populations and reliance on chemical pesticides in agroecosystems. We tested whether the effectiveness of intercropping against herbivorous insects depends on the phylogenetic relatedness of neighboring crops, using butternut squash (Cucurbita moschata) as a focal crop species in a series of different intercropping combinations. We found that increased phylogenetic divergence of...
