Southern Corn Leaf Beetles Found in Lots of Fields

May 11, 2001
In last week's Bulletin (issue no. 6, May 4, 2001), Mike Gray wrote an in-depth article about southern corn leaf beetles. We have received numerous reports about the presence of these interesting pests throughout southern, western, and west-central Illinois since our first report (Bulletin issue no. 5, April 27, 2001) of their presence, and they continue to cause significant damage in some fields throughout the affected area.

With black cutworms and other insect pests working in cornfields right now, proper diagnosis of the pest causing the damage is extremely important. The injury caused by southern corn leaf beetles can be confused with injury caused by cutworms. And as many of you already know, southern corn leaf beetles can be difficult to find. But keep looking if you're having trouble locating the source of the problem. If an insecticide is warranted, you will have to identify the pest correctly to choose the appropriate product.--Kevin Steffey
