Abstract Eight plant oils viz., sunflower oil, soybean oil, karanj oil, sesamum oil, coconut oil, mustard oil, castor oil and neem oil @ 0.5 and 1.0 ml/100 g of groundnut seeds were tested for their efficacy in protecting stored groundnuts against C. cephalonica. Neem oil, karanj oil and castor oil @ 1.0 ml/100 g of seeds proved to be the most effective plant oils as it recorded highest oviposition deterrence (98.01%, 97.55% and 97.28%, respectively), maximum reduction of adult emergence (73.48%, 76.79% and 76.23%, respectively), longest longevity of male (3.00, 3.33 and 3.22 days, respectively) and female (3.67, 4.22 and 4.22 days, respectively) adults, fecundity (37.08, 39.64 and 41.58 eggs per female, respectively) and lowest viability of eggs (54.00%, 60.00% and 58.67%, respectively) after 65 days of seed treatment. None of the plant oils tested at doses had hampered the germination of groundnut kernels during the storage periods up to 120 days.
