Abstrakt: The relative susceptibility of lifestages of seven Bemisia tabaci (Genn.) populations from major cotton growing regions in India to pyriproxyfen has been studied. The results revealed that adults were unaffected at significantly high concentration ie., 200 mg/ l (field recommended dose, <10% mortality), hence adult bioassay was not done. Indore and Amravati populations were the most and least susceptible ones for both egg and nymphal stages; and all the populations were found susceptible to pyriproxyfen with RR ratio of <5, except for Amravati one, revealing low level of resistance with RR ratio (5.04- egg; 5.09- nymph) computed deploying the LC90 and LC50 values.
