Conservation plantings have become an important tool for enhancing the provision of ecosystem services in crop production environments. One such ecosystem service is the predation of crop pests by natural enemies. Natural enemies are a diverse group, spanning multiple insect and arachnid orders, and may respond in different ways to conservation plantings. Similarly, conservation plantings may provide refugia for pest insects and potentially negating any benefits from natural enemies. To better understand the role of conservation plantings in supporting both natural enemies and pest insects, we sweep netted insects in conservation plantings adjacent to soybean fields as well as adjacent soybean fields at varying distances into the field. We quantified abundances of X natural enemy and pest insect groups. Results will be discussed.
