First black cutworm moth trapped in Iowa

About two weeks ago, we sent out a general request looking for cooperators to trap black cutworm moths in Iowa. We use the adult captures to help us predict larval cutting dates in corn. Last night, the first moth was captured in a trap in Muscatine County, Iowa. This is very early to see migratory moths moving up north. I am not sure what this means for spring populations, but last year had higher-than normal trap numbers. As a result, we saw more damaged corn and soybean during establishment. I will keep you updated on trap numbers for 2012 and predicted cutting dates later this spring.
