Insecticide resistance of Helicoverpa armigera

In South India, experiments were carried out to assay the insecticide resistance of Helicoverpa armigera (EPPO A2 pest).
During the years 1989-90 high levels of resistance of H. armigera to cypermethrin were found, but no evidence for resistance to quinalphos or methomyl were observed. However, during the cropping season 1990-91 the tolerance of H. armigera to methomyl increased substantially while the tolerance·to quinalphos increased slightly. Also a slight increase of resistance to endosulfan has been observed.
