More bean leaf beetles were found in central Iowa last year than ever recorded (see the article in the March 17, 2003,Integrated Crop Management newsletter). This historically high population has caused soybean damage, both by feeding injury and transmission of bean pod mottle virus, resulting in reduced yield and seed quality. High bean leaf beetle populations have been partially due to favorable winter conditions, such as mild temperatures or snow cover the past several winters.
