A two year study was undertaken to examine the impact of Solenopsis invicta Buren (Hymenoptera: Formicidae) suppression on soybean pests, beneficial predators, and crop yield. Three treatments were examined an untreated control, Amdro (hydramethylnon) bait, and chlorpyriphos in combination with Amdro. The treatments were successful in suppressing fire ant foraging and abundance in the treated plots. This led to decreased predation on lepidopteran eggs and pupae. An increase was seen in the threecornered alfalfa hopper, Spissistilus festinus (Say) and lady beetles in the treated plots. In 2000, pitfall monitoring revealed ground-dwelling spiders were more abundant in the untreated control. Earwigs were more abundant in both years in the chlorpriphos + Amdro treatment and at times the Amdro alone treatment. The residual toxicity of acephate, chlorpyriphos, methomyl, and l-cyhalothrin on fire ant workers was investigated and dose-mortality curves were developed for each chemical.
