Research

Cynthia Scott-Dupree is a Professor and Bayer CropScience Chair in Sustainable Pest Management (2014-2019) in the School of Environmental Sciences (SES) at the University of Guelph. She has been a faculty member first in the Dept of Environmental Biology and the SES there since 1986. She received her Master of Pest Management (1983) and her Ph.D. (1986) from the Dept. of Biological Sciences at Simon Fraser University under the supervision of Dr. Mark Winston. Dr. Scott-Dupree has supervised 40 graduate students, has edited 3 books and 5 book chapters, and published 67 refereed scientific papers, 37 refereed proceedings papers, 80 technical reports and 30 extension publications.

Her current research interests include sustainable management (IPM) of insect crop pests using environmentally compatible control methods in horticultural, field and greenhouse cropping systems, management of invasive alien insect species, impact of agro-ecosystems on non-target organisms, including beneficial insects such as honey bees, bumble bees, native bees and natural enemies of insect pests (i.e., biological control agents primarily for greenhouse IPM) and the development of standardized methods for assessing the risk of insecticide exposure to non-Apis bees (i.e., bumble bees and leafcutter bees). Cynthia has been involved with method development for studying the impact of pesticides in agroecosystems on bee pollinators in lab and field situations. Since the early 90’s, she has been involved with the supervision of large-scale GLP and other field studies in Ontario – looking at the impact of insecticides on honey bees, bumble bees and leafcutter bees.
