Essential oil of Tulsi was investigated for repellent activity against two stored grain insect pests, Rhyzopertha dominica and Tribolium castaneum. The ethanolic concentrations of oil at 1%, 2% and 3% were tested. It was found that repellent activity was proportional to the concentration and higher concentration has stronger effect. Moreover the repellent effect was better on T. castaneum as compared to R. dominica. T. castaneum showed 95.96, 98.69 and 99.56% repellent activity at 1, 2 and 3% concentration of essential oil respectively. Hence, botanical insecticides might be used as an alternative for grain protection against stored grain insect-pests.
