True Armyworm and Black Cutworm Trap Report

David Owens, Extension Entomologist, owensd@udel.edu

Armyworm and cutworm flights remain low so far but are starting to increase just a bit. We will start checking some of our cutworm traps twice per week to narrow down when a significant moth flight is moving through. This is only the third year that we have been monitoring armyworm, but University of Kentucky has been monitoring armyworm since the 1990s. For trap context, in 2008, they had an armyworm outbreak in small grains; their traps peaked at 600-1700 moths per week.
