Abstract
As I mentioned in last week's newsletter, grape colaspis has caused some early season stand reduction in cornfields in eastern Iowa. On July 19, I was in Harrison County (western Iowa) and in seven first-year cornfields I found adult colaspis beetles (these beetles may not be grape colaspis). They seemed to be most abundant on the green silks, whereas a few were hidden in the leaf axils. One field southwest of Magnolia averaged at least one beetle per plant.
