Wireworm (Agriotes sputator) is an insect pest. It is a native of Europe and western Asia.
The larval stage of agriotes sputator severely infests germinating seeds, roots, root crops, and tuberous crops. In Canada, it is a serious pest; the lined click beetle was responsible for 60% loss to potatoes in a field on Vancouver Island in 1949 and caused significant damage in Yarmouth, Nova Scotia, in 1954. 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.
