Abstract

The black cutworm (BCW) is a migratory pest that cuts corn seedlings and feeds on leaf tissue. Scouting for BCW larvae helps to determine if an insecticide application will be cost effective. When to scout for BCW caterpillars is based on the peak flight of moths and accumulating degree days after the peak flight. A peak flight occurs when eight or more moths are caught over two nights in a wing style trap.
