Economic Importance: Grain is so severely injured by this elaterid in the USSR and Denmark that replanting is sometimes necessary. Great damage to cereals and sugarbeets also occurs in Germany. Forty to 80 percent of plants were killed on hundreds of acres of sugarbeets, oats, and barley in Sweden in an outbreak in 1918. The wireworm is one of the chief soil pests in nursery plantations in the Btitish Isles and is very destructive to young grape stock in such plantings in Italy. In Canada, A. lineatus was responsible for 60 percent loss to potatoes in one field on Vancouver Island in 1949 and was especially damaging to this crop in Yarmouth area (Nova Scotia) in 1954. This species and the related A. obscurus (L.) and A. sputator (L.) are regarded as major pests of cultivated crops in Europe, A. lineatus and A. obscurus are responsible for most of the wireworm injury in Switzerland. A. lineatus was first found in North America in Canada in 1947, A. sputator in 1939, and A. obscurus was thought to have been introduced in 1895-1900 into British Columbia in soil used for packing hop plants. These species have been intercepted at ports of entry on several occasions. Distribution: Canada (British Columbia, Nova Scotia, and Newfoundland), Central Asia, Europe (all), Middle East, Near East, and Siberian area of USSR. Hosts: Wheat, barley, corn, rye and some other grains and grasses, lupine, potato, carrot, tobacco, pea, hop, peach, grape, turnip, lettuce, sugarbeet, cabbage, tomato, flax, buckwheat, Jerusalem artichoke, onion, garlic, clover, rape, sunflower, oak, pine, spruce and General Distribution of Agriotes lineatus (L.)
