Imported Fire Ant (Hymenoptera: Formicidae) Control: Evaluation of Several Chemicals for Individual Mound Treatments1

Abstract
Ten pesticides in various formulations were applied as aqueous drenches, fumigants, or baits to mounds of Solenopsis invicta Buren at rates recommended by the supplier. The most effective chemicals for drenches were acephate 8 or 15.6 EC, carbaryl 23 suspension, bendiocarb 76 WP, chlordane 72 EC, and diazinon 25 EC at application rates of 2.2 to 3.4, 27.2, 4.6, 4.0, and 7.5 g of AI per mound, respectively. Amdro (tetrahydro-5,5-dimethyl-2(1H)-pyrimidinone, [3-[4-trifluoromethyl) phenyl] 1-[2-[4-(trifluoromethyl)phenyl]ethenyl]-2-propenylidene]hydrazone.) 088% bait was very effective at rates of 0.1 and 0.2 g per mound.
