Abstract

The first generation of bean leaf beetles is making an impressive appearance in soybean. Last week, Brad Buchanan, Crop Tech Services, reported fields in Henry County in southeastern Iowa with populations of 50-80 beetles per 20 sweeps. In Story County on July 17, I collected an average of 30 beetles per 20 sweeps with one count as high as 49 beetles in 20 sweeps. These numbers suggest that this first generation will contribute to the buildup of a significantly large second generation that will cause economic damage to soybean pods in these fields.
