David Weaver

Dr. David Weaver serves as a Professor in the Department of Land Resources & Environmental Sciences within Montana State University's College of Agriculture, with cross-affiliations to the Institute on Ecosystems and Pollinator Health Center.

His academic credentials include:

• Ph.D. in Agricultural Sciences, McGill University (1990)
• B.S. in Biological Sciences, Dalhousie University (1984)

Research focuses on developing sustainable solutions for agricultural pest challenges through Integrated Pest Management and biological control systems. His work addresses critical issues in wheat stem sawfly resistance, invasive plant management (toadflaxes, Russian olive), and pollinator health using molecular, ecological, and remote sensing approaches.

Recent publications (2023-2025) reveal consistent emphasis on molecular mechanisms of plant resistance (metabolomics/transcriptomics), hyperspectral detection of pest damage, and biocontrol agent ecology—demonstrating integration of laboratory and field methodologies across entomology, plant science, and ecosystem management.

Key recognition includes:

• Charles and Nora Wiley Faculty Award for Meritorious Research (2015)

Dr. Weaver maintains active research funding and academic engagement through:

• USDA NIFA grant for wheat stem sawfly resistance gene discovery
• Three concurrent Montana Noxious Weed Trust Fund projects (2025) targeting invasive species biocontrol
• Montana Department of Agriculture grant for cowpea agronomy
• Ongoing service in multistate research projects (W2193, NC-213)
• Editorial reviews for major entomology journals

His research group contributes to Montana State University's land-grant mission through extension publications, student mentorship, and collaborative field studies addressing regional agricultural challenges.
