Non-Prey Foods and Biological Control of Arthropods
Non-prey foods are an inextricable part of the diet of most entomophagous species, and thus provide a way in which biological control practitioners can manipulate the efficacy of natural enemies. The unique nutritional ecology of natural enemies comes to play in improving classical and augmentative releases of biological control agents, and providing for the nutritional needs of natural enemies can be a powerful tool that allows land managers to conserve and promote endemic natural enemies within designated areas. Although providing for the nutritional needs of natural enemies intuitively enhances biological control, there are sometimes complex and unintended repercussions on entomophagous communities resulting from this practice. While this fact should not preclude the incorporation of non-prey foods into cropland, both the benefits and limitations of this strategy need to be considered when applying non-prey foods in an IPM context.
