Significant numbers of black cutworm adults (moths) were captured in pheromone traps during April across Iowa. This insect is an occasional pest of seedling corn that sometimes causes significant damage in a few fields. Pheromone trap cooperators reported catching moths across the state in late March and throughout April. Based upon these trap captures, we anticipate that first cutting of seedling corn should occur May 9-10 across southern Iowa, May 18-19 across central Iowa, and May 20-21 across northern Iowa.
