Each year we coordinate a trapping program across Iowa for black cutworm adults (moths) that migrate into the state. The company from which we purchase our black cutworm trapping supplies, unfortunately, sent pheromone that was improperly mixed and therefore not attractive to the male moths. We did not learn of this problem until after the moths had already begun their migration into Iowa, and then it was too late to get new pheromone and have it redistributed.
