Suspected Cry1Ab resistant European corn borer found in NS

In the fall of 2022, a European corn borer (ECB) population was collected near Truro, Nova Scotia near a field where a Cry1F-resistant ECB population was collected in 2018. Based on bioassay tests conducted by Drs. Jocelyn Smith and Yasmin Farhan at the University of Guelph, Ridgetown Campus, results show that the population appears to have reduced susceptibility to Cry1Ab.
