ABSTRACT
Fall armyworm (Spodoptera frugiperda) attacks maize plants at all stages of development, from seedling to tasseling, causing defoliation, killing the young plant, causing grain damage, and reducing yield quantity and quality. The current study was conducted to check the toxicity of two insecticides, i.e. Emamectin benzoate and Lufenuron on 2nd instar larvae of Spodoptera frugiperda under laboratory conditions. The data showed that emamectin benzoate was more toxic insecticide than lufenuron. Emamectin benzoate required the least time to kill the 50% population than lufenuron. Lufenuron has recorded the least toxic insecticide and required a maximum time of 43 h to kill 50% of exposed insects. Fiducial (FL) values of both insecticides were non-significant to each other. The results can help future scientists. Further studies are needed to control this pest on maize crops in field and laboratory conditions.
