Field resistance of Spodoptera litura (lepidoptera : noctuidae) to newer chemistry insecticide indoxicarb in Vidarbha

The present studies were carried out to evaluate resistance in the population of Spodoptera litura Fab. (Lepidoptera, Noctuidae) from eight districts of Vidarbha region in India to indoxicarb from 2011-2013 using standard leaf dip bioassay method. For indoxicarb, resistance ratio compared with a susceptible strain were in range of 2.66 to 6.14 fold. However, relatively low level of resistance to indoxicarb was observed in all eight populations.
