The Department of Entomology was founded in 1896 at Cornell AgriTech in Geneva, New York.

Our mission is threefold: to pursue studies to understand basic and applied aspects of insect biology; to provide a robust and modern curriculum as part of preeminent undergraduate and graduate programs; and to inform and educate the public about the issues related to insects and other arthropods.

Our faculty primarily works on two campuses: Cornell University’s main campus in Ithaca and Cornell AgriTech in Geneva. We also work in two agricultural field stations in New York state. Our department houses some of the world’s preeminent resources for the study of entomology, including one of the world’s largest insect collections, working farms of all sizes, a major honey bee colony and state-of-the-art laboratories.
