Abstract/Contents:"A granular formulation of Scimitar^D]T^D]M (lambdacyhalothin) was evaluated as either individual mound or broadcast treatments for control of the red imported fire ant, Solenopsis invicta Buren. Treatments with Scimitar^D]T^D]M applied to individual mounds were significantly better than the untreated check, but were slower acting than the Dursban^D]T^D]M (chlorpyrifos) standard. By 28-day, both rates of Scimitar^D]T^D]M were providing greater than 88% control of fire ant colonies. Foraging activity was never significantly reduced by individual mound treatments with Scimitar^D]T^D]M, but Dursban^D]T^D]M provided a significant reduction. Scimitar^D]T^D]M broadcast treatments did not provide significant control until after 14 day, and overall mound reduction was ca. 50%. Foraging activity was impacted by the Scimitar^D]T^D]M broadcast treatment, but relatively large numbers of ant foragers were still present. The high initial reduction in ant foraging prduced by Dursban^D]T^D]M began to disappear at 28 days. Foraging activity for ants within a plot was assayed by placing 3 hot dog baited traps near the central area of the plot for ca. 30 min exposure and counting the ants collected. Mound mortality was determined by stomping on the soil near the mound and observing the ant activity or by baiting the center of the mound with a small piece of hot dog and observing for ant foraging from within the colony. No phytotoxicity was observed due to any of the treatments."
