Hosts:

The dusky wireworm has a very broad host range, including many forage crops, crucifer crops, vegetables of many types, corn, flax, grape, lettuce, onion, peach, potato, rape, strawberries, sugar beet, sunflower, tobacco, tomato , turnip, wheat, other small grains and grasses, as well as oak, pine, peach, spruce, and fir.

 

Commodities Affected:
Field Crops, Forestry and Natural Areas, Fruits and Vegetables, Nursery, Ornamentals, and Turf

 

Threat:

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.

 

Distribution:

The dusky wireworm is not known to occur in Indiana.
