Abstract
Abstract The adults and larvae of susceptible, malathion-specific resistant and multi-organophosphorus resistant strains of Tribolium castaneum were exposed to a range of doses of malathion, with and without the addition of the synergist triphenyl phosphate. The compounds were applied by topical application and the mortality response of adults and final instar larvae were compared. In all strains the larvae showed a higher tolerance to malathion than the adults. A comparison of malathion resistance between the strains showed that the resistance factors achieved for larvae were higher than those for adults. The addition of triphenyl phosphate was completely effective in overcoming the resistance in both adult and larval stages of the malathion-specific resistant strain.
