Wireworms can damage corn, resulting in stand loss during the seedling stage.
Wireworms are found most often in grasslands or fields recently planted in sod. Occasionally, they are found in fields without any recent history of grasses. The presence of this pest in Iowa CRP was recently demonstrated in a study by Steve Lefko at Iowa State University. Additionally, he determined that wireworms are more likely to occupy well-drained soils commonly found on ridgetops or hillsides. Wireworms can spend several years in the immature stage during which they feed on newly planted corn seeds as well as roots of established corn.
