Insect surveys were conducted in commercial and experimental potato fields in Palmer, Delta Junction, Fairbanks, and Nenana, Alaska. Tile trap pans and yellow sticky traps were used to collect aphids and leafhoppers, respectively, from April to October, 2003-2005. Insects were collected weekly and identified to genera and species when possible. Ten aphid species were detected; Rhopalosiphum nigrum represented 86 percent of the aphids collected. The green peach aphid, which is consider to be the most effective vector of potato viruses was collected in pan traps and found colonizing potatoes. Yellow sticky traps captured six genera of leafhoppers including important vectors of phytoplasmas to potatoes. Macrosteles spp. was the most abundant leafhopper collected.
