    Abstract : In 1992, sentinel squash plants treated with carbofuran successfully attracted and killed Anasa tristis and Acalymma vittatum emerging from overwintering at 5 locations in Atoka County, Oklahoma. In 1993, responses of the pests to carbofuran-treated squash trap plants and to Adios or Adios-AG attracticidal baits were compared in <1.0-ha plots of seedling cantaloupe, squash and watermelon at Lane, Oklahoma. Regardless of crop, pest populations were highly attracted to 'Lemondrop' squash trap plants that amounted to <1% of the total crop area. Squash trap-plants attracted an estimated 39.7, 32.4 and 66.3% of the A. vittatum population, respectively, observed in fields of cantaloupe, squash and watermelon seedlings. In cantaloupe and watermelon, squash trap-plants attracted >90% of the estimated Anasa tristis population but were less effective in squash. In all cases, squash trap plants treated with carbofuran killed >90 and 16-37%, respectively, of the Acalymma vittatum and Anasa tristis found on the plants. Single applications of attracticidal baits provided up to 70% Acalymma vittatum mortality for 3-5 days post treatment. Studies conducted in 1994 showed that significantly greater numbers of Coleoptera, primarily Diabrotica undecimpunctata howardii, were attracted to 'Blue Hubbard' than Lemondrop squash trap plants that were treated with systemic insecticides, carbofuran at 0.15 g a.i. or imidacloprid at 0.04 g a.i., and positioned in a field of watermelon. Imidacloprid was as effective as carbofuran, each causing >90% beetle mortality. In this study, an estimated 46.7% of the total beetle population was attracted to the squash trap plants. Results from these studies suggest that minimal plantings of systemically treated squash can be used effectively to suppress early-season populations of A. vittatum and Anasa tristis in seedling cantaloupe, squash and watermelon.
