Abstract
Abstract In the northwestern United States, insect pests of potatoes (Solanum tuberosum L.) have typically been controlled using broad-spectrum insecticides. However, the loss or impending loss of many broad-spectrum chemicals is increasing the use of selective insecticides, and organic potato production is growing in the region. In the 2001 and 2002 growing seasons, we intensively sampled the arthropods in 31 (14 in 2001 and 17 in 2002) production potato fields under three pest management regimens: conventional fields treated with broad-spectrum insecticides (Hard), conventional fields treated with selective insecticides (Soft), and organic fields treated with insecticides certified for organic production (Organic). All fields were within the Columbia Basin of Washington, grown under center-pivot irrigation. We sampled arthropods using three techniques: D-vac suction sampling, pitfall trapping, and visual searching. Geocoris spp. and Nabis spp. bugs (Hemiptera) and spiders (Araneae) were the most abundan...
