Developmental biology on Spodopterafrugiperdausing eleven different host plants with maize as a control was studied under laboratory condition. The neonates were fed with hosts of grain sorghum, blackgram, greengram, cowpea, castor, amaranthus, papaya, fodder sorghum, bermuda grass, Cyperus and maize. The duration of larva, pupa and adult and mean larval and pupal were recorded. The lowest larva-adult duration was found in castor and sorghum and highest in Bermuda grass. The highest mean larval and mean pupal weight wasfound in castor and lower in pulses. The further study deals with the consumption, digestion and utilization indices of S. frugiperda larvae fed with five hosts. Though S. frugiperda is a polyphagous pest, it feeds on many host but in this study, it showed more preference for castor. This study reveals the adaptability and utilization ability ofS. Frugiperda larvae on various hosts.
