by Bruce Potter European corn borer Entomologists at the University of Minnesota continue to document and understand changes in European corn borer (ECB) populations in our state. Each fall, a number of corn fields are surveyed for the presence of corn borer damage and overwintering corn borer larvae. During the growing season weekly updates of ECB moth captures in black light traps are made available: https://www.vegedge.umn.edu/moth-data/ecb-info . Funding from the Minnesota Corn Research and Promotion Council has provided us an opportunity to improve these efforts.
