The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) is a polyphagous Lepidopteran pest recently invaded in India on maize, sorghum and sugarcane crop causes severe economic losses. This pest has been identified by morphological and DNA barcoding methods. The present study revealed that the percentage damage was between 10 to 40% in different hybrids, inbred lines of maize and sweet corn. FAW larvae found during the vegetative stage of the crop i.e. knee height stage and continues upto cob formation stage. Dark brown grown larvae having inverted ‘Y’ shape on the head with remarkable elevated distinct four dark coloured black spots (Pinacula) arranged in square on the abdominal segment in 8th segment whereas trapezoidal pattern on 9th abdominal segment.
