Entomology at Oklahoma State University offers you the opportunity to explore the diversity of nature through the study of arthropods and their interactions with plants, animals and human culture. Specialized course work includes insect identification, biology, ecology, physiology, biochemistry, population dynamics, medical and veterinary entomology, and pest management.

Why Study Entomology?

Insects are important in many ways. Some are pests and destroy our food and fiber crops, forests, homes and structures. Others affect human and animal health by transmitting diseases. Many are beneficial to humans and essential to the Earth’s ecology by providing pollination, decomposition, nutrient recycling, control of agricultural pests, control of invasive plants and food for wildlife. Despite their small size, insects have a significant impact on the environment and economy and, therefore, our society.
