Vaughn Walton

Dr. Vaughn Walton is a Professor in the Department of Horticulture at Oregon State University and a core researcher at the Oregon Wine Research Institute. He specializes in integrated pest management (IPM) for small fruit and tree nut crops, focusing on economically significant pests like Spotted-Wing Drosophila (SWD) and the Brown Marmorated Stink Bug (BMSB).

• Ph.D., Entomology, University of Stellenbosch (2003)
• M.Sc., Integrated Pest Management, University of Stellenbosch (1998)
• H.E.D., Teaching Higher Education Diploma, University of Stellenbosch (1993)
• B.Sc., Botany and Zoology, University of Stellenbosch (1992)

Walton’s research emphasizes ecologically sustainable pest control strategies. His work combines physiological, behavioral, and environmental studies to time interventions during pest vulnerability periods. Key areas include biological control, mating disruption, and pesticide application optimization. He has led extramurally funded programs targeting SWD and BMSB, with a focus on minimizing agricultural impact while maintaining productivity.

Recent publications highlight advancements in pest monitoring, chemical control, and biological strategies. Studies explore SWD host range, irrigation effects on biocontrol, and novel materials like food-grade gums to disrupt pest behavior. His team’s research on grapevine red blotch virus transmission by mealybugs informs vineyard management practices.

Scientific accolades include:

• World’s Most Influential and Highly Cited Researcher (2019-2021)
• Briskey Award for Faculty Excellence (2021)
• Erasmus Mundus Teaching Award (2019)
• Entomological Society of America IPM Awards
• Oldfield/Jackman Team Award (2013)

Walton mentors graduate students in the Entomology and Horticulture programs and collaborates with lab members Kyoo Rok Park and Betsey Miller. He contributes to extension publications, including the PNW Insect Management Handbook and guides for hazelnut and grape IPM. His outreach includes training on pest identification, monitoring techniques, and sustainable production systems.
