Bertha Armyworm Monitoring

The annual monitoring program for bertha armyworm moths is now underway across the prairie region, thanks to volunteers who are hosting pheromone traps!

This monitoring program helps determine where there might be risk of bertha armyworm damage to crops, but does not replace scouting for larvae in individual fields.

Learn more about monitoring bertha armyworm adults, scouting for larvae, and the economic thresholds for bertha armyworm in this Insect of the Week article.
