Metasystox-R, Fulfill, Actara, Emamectin benzoate, Orthene (two formulations), Bidrin, Provado (two rates) and an untreated check were compared for control of fleahoppers and effect on beneficial arthropods. Two insecticide treatments were spaced 7 days apart. Insecticide treatments significantly reduced fleahopper numbers as measured 3 and 6 days after each treatment. Least disruption of predators (not significantly different from the untreated check) was found in Fulfill, Bidrin, Orthene (both formulations) and Metasystox-R treated cotton. Significant differences were not observed in lint yield; however, a numerical increase did occur in all but one of the insecticide treatments (average of 29.7 lb/acre). Important changes in fiber characteristics did not occur.
