Significant numbers of black cutworm adults (moths) were captured in pheromone traps during April across Iowa. Even though this insect is an occasional pest of seedling corn, it deserves our attention because of its potential for causing economic damage. Based upon these trap captures, we anticipate that first cutting should occur May 8 (southwestern corner of Iowa), May 11 (the remainder of Iowa except the northeastern corner), and May 18 (northeastern corner of the state).
