The Entomology (ENT) option at Oregon State University embodies the Land Grant mission of integrated research, teaching, and extension in the context of understanding the basic biology of insects and, with this knowledge, then working with insects in natural and/or managed environments. The discipline of entomology at Oregon State University covers behavior, ecology, evolution, physiology, systematics, molecular biology, chemical ecology, plant-insect interactions, pollination by honey bees and native bees, biological control, integrated pest management, and insecticide toxicology. Oregon State Entomology addresses insect-related issues in aquatic and terrestrial systems in natural, agricultural, forested, and urban environments. Entomologists collaborate with plant scientists, physiologists, pathologists, soil scientists, geneticists, molecular biologists, and experts in other fields.
