Abstract

Fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae) is most destructive specie of genus Spodoptera for several agricultural crops. In Pakistan's Sindh province, the invasive fall armyworm Spodoptera frugiperda was first documented causing serious maize damage in 2019. There is need to develop management strategies against this pest in the country. The current study was conducted to check the toxicity of different insecticides against FAW in maize field. The results showed among tested insecticides, deltamethrin was recorded most toxic insecticide followed by chlorantraniliprole and emamectin benzoate. At 1d days after first spray, least number of larvae were recorded with deltamethrin (0.07 larvae/plant), chlorantraniliprole (0.11d larvae/plant) and emamectin benzoate (0.13 larvae/plant). After three days application of first spray, significantly a minimum number of larvae were recorded with deltamethrin (1.11bcd larvae/plant) chlorantraniliprole (1.13d larvae/plant) and emamectin benzoate (1.17d larvae/plant). The maximum and minimum population of larvae was recorded at 1^st day of first spray and 14 days of spray, respectively. The least number of larvae were recorded at 14 days of second spray. At 14 days after 2^nd spray, 0.07ab, 0.10e and 0.10de larvae per plant were recorded with deltamethrin, chlorantraniliprole and emamectin benzoate, respectively.
