Though typically not initially impressive (see “Western Bean Cutworm Pheromone Trap Report”) this is just the beginning of an extended moth emergence and flight, with peak activity expected 2-3 weeks from now. Those in high-risk areas, i.e., sandy soils, high moth flight, northern Indiana counties and western bean cutworm history, should be gearing up for field scouting of corn, even those with Bt-traits.
