Petroleum ether extracts of V. officinalis. P. harmala, S. lappa and A. indica oil were studied for their repellent effect against T. castaneum. Out of these plants, V. officinalis showed highest (80.83%) repellency during the first week at 1000 mug/cm2, which was significantly higher than 58.83% in A. indica oil (used as standard). Plant extracts showed highest repellency during the first week which significantly, decreased in the second and fourth weeks and completely exhausted after the eighth week. Application rate of 1000 mug/cm3 was the most effective followed by 500 and 250 mug/cm2. Petroleum ether extract of V. officinalis having 49.25 and 42.25% at 1000 and 500 mug/cm2 and S. lappa having 47.75% average repellency were promising repellents against T. castaneum adults over eight weeks period, respectively, as against 56.63% in A. indica oil.
