A survey is reported of resistance to DDT, dieldrin, fenitrothion and malathion in last instar larvae from cultures of Pladia interpunctella (Hübner), Ephestia cautella (Walker) and E. kuehniella Zeller, established from samples collected in New South Wales, 1974‐1977. Resistance to DDT and dieldrin was detected in most samples. Resistance to malathion was widely distributed in P. interpunctella and E. cautella. Fenitrothion resistance in these species was not as widespread as the former resistance. Malathion resistance was diagnosed in E. kuehniella but further sampling is required to show its distribution. Fenitrothion resistance was not diagnosed in larvae of this species. Pre‐treatment of larvae with triphenyl phosphate was found to be a useful indicator of the type of malathion resistance present.
