Studies on life cycle of fall armyworm (Spodoptera fugiperda, J. E. Smith)reared on rabi sorghum leaves

Abstract

Studies on life cycle of fall armyworm (Spodoptera frugiperda J. E. Smith) reared on fresh sorghum leaves wasconducted 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, ovipositionand post- oviposition, fecundity and number of egg masses/female were recorded. The total egg, larval and pupal periodranged 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.
