Bean leaf beetles are still extremely abundant in some fields and are continuing to cause damage to pods. I swept one field south of Ames on September 8 that was just beginning to turn yellow. In 10 sweeps I collected 229 bean leaf beetles, or as best as I could count! In an adjacent variety where approximately half of the leaves were yellow, I collected 82 beetles in 10 sweeps. It was not uncommon for 60-70 percent of the pods on the upper half of the plants to be heavily scarred or flat with no developing seeds.
