The present study was carried out to determine the synergistic effects of edible oils (Palm, sunflower, cotton seed, rice bran, castor, sesame) and non-edible oils (Neem, pongamia, citronella, rosemary, thyme, jatropha and lemongrass) in the suppression of malathion resistance Sitophilus oryzae (L.) and Tribolium castaneum (Herbst.) by adopting residual film method. Among edible oils, sesamum exhibited high level of malathion resistance suppression in S. oryzae with SR of 74.48, followed by pongamia, rosemary, rice bran, thyme and neem oils exhibited moderate level of synergistic activity with suppression rate (SR) of 45.99, 45.99, 43.16, 42.61 and 35.87 per cent, respectively. The moderate level of malathion resistance suppression was observed from both non-edible and edible oils against T. castaneum. Among non-edible oils, pongamia, rosemary, thyme and neem recorded SR of 47.54, 42.57, 35.81 and 28.93 per cent respectively. The edible oils, sesame, rice bran and cotton seed recorded SR of 42.17, 33.34 and 33.34 per cent respectively. However, none of the plant oil was toxic when applied alone.
