Abstract

Black cutworm moths were caught in pheromone traps across Iowa throughout much of April. Several "waves" of moths flew in from southern states during April 8-12. Captures of these early moths primarily occurred in the central and southern Iowa counties. Another wave of moths flew farther north, beginning on April 14, with many traps catching moths during April 15-23. From these collections, we can project the likely first cutting dates of seedling corn across Iowa. Based on current temperatures and predicted temperatures over the next 3 weeks, we anticipate the first cutting of corn on May 10 in southern Iowa (see map).
