Abstract
Fall armyworm, Spodoptera frugiperda (J.E Smith) (Noctuidae: Lepidoptera) has become a serious pest in maize. In our study, we evaluate the efficacy of Teflubenzuron (Nomolt® 15% EC), Emamectin benzoate (Proclaim® 5% SG) and Alfa-cypermethrin (Fastac® 5% EC) on the fourth instar larvae of the fall armyworm (FAW), Spodoptera frugiperda (J.E Smith) (Lepidoptera: Noctuidae) both laboratory and field experiments. The results revealed that the LC50 values obtained were 0.18 ppm, 0.019 mg/ml, and 0.6046 mg/ml for S. frugiperda larvae treated with different concentrations of Teflubenzuron, Emamectin benzoate and α-cypermethrin respectively. The study, investigates the prolongation of larval duration, decreasing both pupation % and pupal duration. Field application of Teflubenzuron, Emamectin benzoate and α-cypermethrin against the fall armyworm (FAW), Spodoptera frugiperda was expressed as a percentage reduction of larval population and residual toxicity. Conclusion of our study that the insecticide Teflubenzuron, Emamectin benzoate and α-cypermethrin were efficient and can be recommended to control the fall armyworm (FAW), S. frugiperda.
