Abstract

Iowa State University researchers are seeing green cloverworm defoliating soybean in central Iowa (Fig. 1). The caterpillars are a rare pest of soybean in Iowa, but researchers have reported higher than normal populations this year. These moths migrate into Iowa from southern states each year. The last major outbreaks occurred in the 1970s (Fig. 2).
