Objective: The present investigation was aimed to assess the impact of five plants oil for their\udinsecticidal and repellent activity against Tribolium castaneum (Herbst), a stored grain pest and\udthey were tested in the laboratory. Method: Five plants oil Citrus autantium, Cinnamomum\udzeylanicum, Gaultheria fragrantissima, Lavandula officinalis, and Ocimum sanctum were\udevaluated for their insecticidal and repellent activities against T. castaneum by adapting the\udstandard protocol in vitro. Results: In Tulsi oil showed powerful repellent against T. castaneum\udbeetles at both the concentration and this property can be clearly seen from the values at 5毺 1\ud(-0.60 and -0.73 in 1h and 6hr respectively) and 10毺 1 (-0.56 and -0.81 in 1h and 6h respectively).\udTulsi oil had more repelling property than other oil tested here against T. castaneum. Maximum\udpercentage of mortality (76 and 92% at 48h and 72 hours after treatment respectively) in Tulsi oil.\udWintergreen oil showed 86% mortality at 72 hours after treatment. Conclusions: The present\udwork for botanical products to control the insect pest of stored grain T. castaneum .These results\udsuggest the presence of actives principles in the plant oils. Further exploration of active\udprinciples and their structural elucidations are underway
