The idea that noncrop habitat enhances pest control and represents a win—win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are measured. Here, we use a pest-control database encompassing studies and 6, sites worldwide to model natural enemy and pest abundances, predation rates, and crop damage as a function of landscape composition.
