Image: In Minnesota, corn earworm (CEW) is primarily a pest of sweet corn. Each year, CEW migration is variable, making it essential to monitor adult population levels with either a Hartstack pheromone or a blacklight trap. We have found that the Hartstack pheromone trap provides consistent results in the Upper Midwest region.
