Abstract

Fall army worm (FAW) Spodoptera frugiperda (J E Smith) is a highly destructive invasive insect pest. Its incidence was observed during post kharif season 2019 at Old Goa, and it ranged from 43 to 83% @ 0.67 larvae/ plant with a maximum of 1.16 larvae/plant during vegetative stage, and it was more than the reproductive stage. The mtCO1 analysis of the populations from Goa revealed the presence of both Rice (R) strain and Corn (C) strain which feed on fodder maize and sweet corn, and this confirms the prevalence of both the strains in Goa on fodder maize.
