To ensure healthy forests for the future, it's necessary to understand the role of insects and diseases in forest ecosystems. Forest entomologists and pathologists study the biological and ecological aspects of insects and diseases in relation to the management of forests and urban forests.

Graduate studies and research in forest entomology and pathology at MSU focus on the impacts of insects and diseases, insect biodiversity, the effects of environmental stress on forest insects and diseases and developing longterm strategies to control forest pests. As an enrichment to the learning environment, students may collaborate with scientists and pest managers from the MSU Integrated Pest Management Program, Michigan Department of Natural Resources, and the U.S. Forest Service, and may participate in forest and Christmas tree extension activities.
