This collection contains research and academic papers on entomology (8 items), three of them written by Hatch’s students at the University of Washington in the 1930s; also, general correspondence and brochures, and programs concerning pest control conferences.

This collection is comprised of research conducted by faculty and students at the College of Agricultural and Life Sciences from 1922-1975. The research and annual reports in this collection are focused on the plant pathology of crops within the Pacific Northwest and Great Plains regions. Field and experimental plots are shown along with potential disease vectors (insects and parasites) and equipment used throughout the research.

Weekly, monthly, quarterly, and annual reports from stations chiefly in Idaho, Oregon, and Washington state concerning pea weevils, pea aphids, and sugar beet insects. Included are a few similar reports issued by the University of Idaho Research and Extension centers at Kimberly and Tetonia, and other agencies.
