Abstract: Diamondback moth, Plutella xylostella (Linnaeus.) is a key pest on Brassicaceae crops causing severe yield loss worldwide. Despite of such efforts, growers are unable to control the damage. Its regular incidence often incited the farmers to spray insecticides. Due to ineffectiveness of insecticides, impelled the growers in India towards organic farming. Present study was designed to study the efficacy of the anti-insect activities of hexane, ethanol and ethyl acetate extract against diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), as an alternative to insecticides. Among the extracts tested, Cent per cent mortality was observed in hexane and ethyl acetate extracts of P. juliflora at 0.6 per cent concentration, and 80 per cent mortality was observed in ethanol extract at 0.6 per cent concentration respectively.
