Insect species outnumber all other life forms combined. We truly live on a planet of insects!

The Department of Entomology at The Ohio State University is the only university department in Ohio focused on the study of insects. We use insects as model systems to further fundamental understanding of molecular biology, physiology, genetics, ecology, and evolution. We provide instruction at the undergraduate (major and minor) and graduate levels (M.S. and Ph.D). Our extension and outreach programs provide non-biased, research-based information to stakeholders to help protect crops, natural resources, structures, and human and animal health.

We invite you to explore, learn, study and research with us!
