Rate My Professor David Weaver

David Weaver serves as Professor of Entomology in the Department of Land Resources and Environmental Sciences at Montana State University, contributing to Agricultural and Veterinary Science through his expertise in pest management. He obtained his Ph.D. in Insect Chemical Ecology and Behavior from McGill University in 1990 and his B.S. in Chemistry from Dalhousie University in 1984. Weaver's academic career includes postdoctoral positions at USDA-ARS Stored-Product Insects Research and Development Laboratory in Savannah, Georgia (1992-1994), and Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, Florida (1994-1997). He joined Montana State University as a Postdoctoral Research Associate in the Department of Entomology (1990-1992), advancing to Research Assistant Professor (1997-1999), Research Associate Professor (1999-2002), Associate Professor (2002-2014), and full Professor of Entomology since 2014 following an administrative reorganization.

Weaver's research specializes in sustainable management of agricultural pests, focusing on biological control, host plant resistance, and chemical ecology. His work addresses key challenges such as the wheat stem sawfly (Cephus cinctus), stored-product insects, and biological control of invasive weeds like Dalmatian toadflax and saltcedar. Select publications include 'Aggregation in yellow mealworms, Tenebrio molitor L. (Coleoptera: Tenebrionidae) larvae: I. Individual and group attraction to frass and isolation of an aggregant' (Journal of Chemical Ecology, 1989), 'The effect of larval density on growth and development of Tenebrio molitor' (Journal of Insect Physiology, 1990), 'Efficacy of linalool, a major component of Ocimum canum Sims (Lamiaceae), for protection against postharvest damage by certain stored product Coleoptera' (Journal of Stored Products Research, 1991), 'Cultivar preferences of ovipositing wheat stem sawflies as influenced by the amount of volatile attractant' (Journal of Economic Entomology, 2009), and 'Identification of novel QTL for sawfly resistance in wheat' (Crop Science, 2010). He has been honored with the Charles and Nora Wiley Award for Meritorious Research from Montana State University (2015), induction into the National Academy of Inventors (2014), Outstanding Paper for 2010 in Invasive Plant Science and Management (co-author, 2011), and served as Editor-in-Chief of the Journal of the Arkansas Academy of Science from 1998-2002. His contributions extend to numerous presentations on integrated pest management and weed biocontrol.
