Abstract/Contents:"Treatments of Talstar^D]T^D]M (bifenthrin) were compared with a standard treatment of Dursban^D]T^D]M (chlorpyrifos) granular treatment and an untreated check. Mound mortality was determined by stomping on the soil near the mound and observing the ant activity. All treatments provided greater than 74% control of colonies within 1 wk after applications and were significantly better than the untreated check plots. Broadcast applications of Talstar^D]T^D]M 0.2G in combination with individual mound treatments of either Talstar^D]T^D]M 0.66F used as a mound drench provided 86-100% control of colonies at 1 wk with continued control throughout the 12-wk study. Secondary treatment of individual mounds provided significantly better control than the broadcast treatment alone. A mound only treatment with the Talstar^D]T^D]M 0.66F was not significantly different from the other Talstar^D]T^D]M treatments where a broadcast treatment was followed by individual mounds drenches. In this test, Dursban^D]T^D]M 1G provided good initial control at 1 wk, but fell below 60% before the 12th week when it provided no control. Foraging activity was assayed by placing 3 hot dog baited traps near the center of each plot for ca. 30 min exposure and counting the ants collected. Pretreatment foraging counts averaged from 187 to 271 RIFA per bait station. All of the Talstar^D]T^D]M and the Dursban^D]T^D]M were severely limiting RIFA foraging, but a significant population (121/bait trap) had began to forage in the Talstar^D]T^D]M 0.66F mound-drench only treated plots. By 6 and 8 wk, the impact of the secondary mound drenches was very apparent with means less than 12 ants in any of the plots. Also at 8 wk, significant foraging was already present in the Dursban^D]T^D]M plot. No phytotoxicity was observed due to any of the treatments."
