Efficacy and insect resistance management of new insecticidal proteins targeting western bean cutworm in Ontario

Western bean cutworm (WBC) is the most important corn pest in Ontario and lack of control can reduce grain yield and quality due to insect feeding and mycotoxin contamination. Unlike other primary corn pests, WBC are not controlled by most transgenic corn expressing Bt proteins. Monsanto has developed new insecticidal proteins to which WBC are susceptible according to preliminary research. To support long-term use of these promising management tools, this project aims to generate information necessary to develop an insect resistance management (IRM) plan.
