We study orchard arthropod communities, population dynamics, and trophic interactions as they respond to climate change and invasive species in the Great Lakes ecosystem. Our applied research and extension program uses the tools of chemical, behavioral, and landscape ecology, and phenological and environmental modeling to develop and improve IPM practices that are sustainable and climate-smart. This includes practices to improve above and below ground biodiversity in support of biological control and running efficacy trials to test both conventional and organic pest management options that work for the Michigan tree fruit industry and for orchards in the Great Lakes region.
