Department of Entomology

A life science that’s critical for our health, our food, and our environment.

Entomology is the study of insects, the predominant species on Earth. With more than a million known species, insects significantly affect our world. The Department of Entomology conducts innovative research in this realm, leading to improved human and animal health, quality of life, and sustainability of our food and ecosystems.


Whether teaching an undergraduate course in the Entomology minor program or a graduate seminar, our top-notch faculty are dedicated to their students. Our faculty is associated with teaching and advising for the undergraduate Entomology minor and Plant Sciences major. Our graduate degree programs in Entomology encourage students to conceive and implement novel research within the insect sciences.


Penn State is a Tier 1 Research University. As such, our students participate in meaningful research. Our robust research programs in chemical ecology, pollinators, infectious disease, and insect biology and management are among the nation’s best.
