Abstract

The grape colaspis is a root-feeding pest of crops, occasionally injuring corn. Historically in Iowa, it was a pest in crop rotations where corn followed red clover. As Iowa agriculture placed a greater emphasis on row crops (primarily corn and soybean), the incidence of grape colaspis infestations declined. However, in recent years (since 1999) the grape colaspis has reemerged in modern crop rotations causing damage to corn following soybeans. Significant populations in seed corn and commercial corn following seed corn have been observed in central Iowa.
