The Department of Agricultural Biology at Colorado State University is committed to excellence in the creation and dissemination of knowledge about insects, plant pathogens, and weeds. Further, Agricultural Biology applies this knowledge to solving practical problems related to: (1) management of pests in production agricultural systems, in natural resources and recreational environments, and in residential and public areas; (2) environmental quality, and (3) human and animal health. The Department encompasses the disciplines of entomology, plant pathology, and weed science – thus providing unique opportunities to address critical issues that cut across disciplinary boundaries. Agricultural Biology focuses its teaching, research and outreach missions in four program areas each of which involves all three of the department’s disciplinary roots in entomology, plant pathology, and weed science. These programs are: 1) Genomics and Molecular Biology, 2) Ecology and Biodiversity, 3) Biology and Management of Invasive Species, and 4) Integrated Pest Management. Agricultural Biology emphasizes knowledge of pests and related organisms; the roles that they play in ecological, economic and social systems; and the application of such knowledge to developing economically and environmentally sound solutions for practical problems. Being interdisciplinary in nature, Agricultural Biology values cooperative and collaborative efforts with other units within the University, as well as other relevant entities in the Colorado and beyond. The C. P. Gillette Museum of Arthropod Diversity houses more than three and a half million specimens and has excellent representation of most orders of insects, especially Rocky Mountain species, but also southwestern species. The collection houses holdings of national importance in the aquatic insect orders, the Lepidoptera (butterflies and moths), the Diptera (flies, gnats and mosquitos), and the Hymenoptera (ants, bees, wasps and relatives). The associated Bruner Family Library contains important systematic literature. Research, undergraduate and graduate training, and outreach activities are prominent among museum-related activities.
