We report here the occurrence of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) in India, which is a devastating pest in American continent on several crops1. S. frugiperda is a polyphagous pest that causes significant losses to agricultural crops.Full Text

A key strategy for delaying the deve-lopment of resistance among cotton bollworms to the Bt toxins is ‘refugia’. This refers to the cultivation of a small proportion of non-Bt-cotton alongside Bt-cotton, in order to maintain a consi-derable population of bollworm adults that are not selected for by the Bt toxins1–3 . The unselected population of bollworm adults, by means of mating with, if any, a small number of selected individuals, is expected to reduce the rate of resistance development4,5 . Thus, with the purpose of implementing the refugia strategy, farmers purchasing Bt-cotton seeds have been provided with a prescribed quantity of non-Bt seeds for simultaneous planting. However, Indian cotton farmers, most of whom are small or marginal, have barely taken the risk of planting non-Bt seeds, thus leading to gross non-compliance of the pre-scribed refuge requirement. This non-compliance has been attributed to the development of resistance recorded among the bollworms against the Bt toxins 6–8 .Full Text
