Effects of gamma radiation and insecticide treatment (films) on the adults of susceptible and insecticide resistant strains of tribolium castaneum (Herbst)

Combined effect of gamma radiation and insecticides on the adults of susceptible and lindane, DDT and malathion resistant strains of Tribolium castaneum (Herbst) was studied. Observations revealed that when the insects were first irradiated with 10 Krad dose of gamma radiation and then exposed to different concentrations of the above insecticides, applied as films, the irradiated and non-irradiated insects showed no significant difference in their degree of susceptibility to the insecticides tested, indicating that pretreatment with gamma radiation did not alter the response of T. castaneum to the insecticidal treatment.
