First-Generation European Corn Borers Are No-Shows in 1999

July 2, 1999
We have passed through the time of year during which first-generation European corn borers should have made their presence known, and the reports from the field have been almost unanimous: We can't find very many. I received one report of about 40 percent infestation in a cornfield in Bureau County, but that level of damage has been a rare exception, not the rule.

In just a couple of weeks, we will begin watching for second-generation corn borers. In fact, the time for emergence of first-generation adults in southern Illinois is almost upon us. If many of the first-generation corn borers survived to adulthood, we should not drop our guard. In some years throughout our history with this pest, a punishing second generation has followed a meager first generation. As moths begin to emerge and people begin to collect them on their car windshields at night, we'll keep you posted.--Kevin Steffey
