In present experiment, three insecticides including triazophos, bifenthrin and cypermethrin, were used against pink boll worm as compared to control in mortality tests to observe their survival on sprayed cotton leaves under laboratory conditions. Three insecticides were tested for pink boll worm resistance evaluation as compared to control under field conditions. Results showed that among three tested insecticides named triazophos; bifenthrin and cypermethrin, triazophos showed high resistance against pink boll worms followed by bifenthrin and cypermethrin under laboratory and field conditions. Mortality was higher in case of triazophos while it was comparatively low in case of bifenthrin and cypermethrin. Field studies showed that population dynamics were lower in case of triazophos sprayed field while it was higher in bifenthrin and cypermethrin sprayed fields as compared to control. So ultimately it can be asserted that triazophos can show high level of resistance for controlling pink boll worms in cotton.
