ISU extension field crop specialists have reported that first-generation damage by European corn borer is light across Iowa. First-generation moth flights were apparently cut short by the cold, wet weather the first week of June. Some producers might think that second-generation European corn borer damage also will be averted because there will be fewer moths to lay eggs and thus, lower numbers of larvae emerging. This is not necessarily true.
