The dusky wireworm is considered a major pest in Europe and western Asia. The larval stage of the dusky wireworm severely infests germinating seeds, roots, root crops, and tuberous crops. In Canada, this is a serious pest. It is highly likely that this species was probably unintentionally introduced very early into eastern and western Canada with dry ballast material used in the sailing ship era, or with the importation of nursery stock associated with soil.



The dusky wireworm is not known to occur in Indiana.
