Entomology is the field of biological science concerned with the study of insects and their relatives in relation to humans, other animals, plants and the environment. Entomologists play critical roles in securing food, fuel and fiber; protecting human health; and supporting natural resources and biodiversity. Students interested in pest management, conservation, ecology, private industry and government-related careers will benefit from a major or minor degree in entomology.

Entomology students are interested in supporting ecosystems to produce food and fuel; protecting human health; and supporting natural resources and biodiversity. The entomology undergraduate program leads to a Bachelor of Science degree. As an Entomology major, students acquire broad training in science, technology and math as well as focused studies on the identification, structure, physiology, ecology and management of beneficial and harmful insects and their ecosystems.

Students often gain practical experience through field and laboratory research projects and work experience through employment in the department. Internships and study abroad experiences are strongly encouraged. An entomology minor is available to students who wish to augment their major focus with an understanding of insects and their impact on human, managed and natural systems.

Entomology is important to students interested in careers that involve: research, education, outreach, natural resource management, conservation, pest management, human and veterinary medicine, forensic investigation, bio-monitoring, environmental assessment, molecular biology, toxicology, private industry and business. Entomology graduates are also well positioned to enter masters, doctoral and professional degree programs.

“Entomology really isn’t just about bugs. Insects are important in our changing society. They have implications toward sustainability, health, globalization, economics and the well-being of our planet. When we study bugs, we are actually studying much, much more.” - Courtney Larson
