Studies on life cycle of fall armyworm (Spodoptera fugiperda, J. E. Smith) reared on rabi sorghum leaves.
Studies on life cycle of fall armyworm (Spodoptera frugiperda J. E. Smith) reared on fresh sorghum leaves was conducted at the Department of Agricultural Entomology, College of Agriculture, Dharwad during the rabi season of 2019. The number of egg per egg mass, duration of egg mass, larvae, pupae, adult life, adult longevity, pre-oviposition, oviposition and post-oviposition, fecundity and number of egg masses/female were recorded. The total egg, larval and pupal period ranged between 4 to 4.33, 15 to 17 and 6.33 to 9 days, respectively. Thus the total life cycle had a range of 30 to 35 days.
