Sticky traps were used to measure how tree shelterbelts influence the abundance of crop insect pests and beneficial arthropods in muskmelon (Cucumis melo L.) plots in eastern Nebraska. Abundance of striped cucumber beetles {Acalymma vittatum Fabricius (Coleoptera: Chrysomelidae)} , southern corn rootworms {Diabrotica undecimpunctata howardi Barber (Coleoptera: Chrysomelidae)}, and northern corn rootworms {D. barberi Smith & Lawrence (Coleoptera: Chrysomelidae)} was similar in exposed and sheltered plots. Western corn rootworms {D. virgifera LeConte (Coleoptera: Chrysomelidae)} were significantly more abundant in exposed plots. More lady beetles (Coleoptera: Coccinellidae) and ichneumonid wasps (Hymenoptera: Ichneumonidae) were caught on traps in sheltered plots than exposed plots, especially during June. Few spiders (Aranae), lacewings (Planipennia), or braconid wasps (Hymenoptera: Braconidae) were caught in either treatment.
