Abstract
Adults of Sitophilus oryzae and Rhyzopertha dominica and adults and eggs of Corcyra cephalonica were exposed to essential oils of geranium (Geranium viscosissimum), lemongrass (Cymbopogon flexuosus) and peppermint (Mentha piperita) in the fumigation chamber. At 48 h exposure, complete mortality of adults of S. oryzae was recorded at 100 and 150 µl/250 ml of peppermint oil. In the case of R. dominica, 100% mortality was observed in all the doses (50, 100, 150 & 200 µl/250 ml). C. cephalonica was not sensitive to peppermint at 5 µl/250 ml. In the case of eggs (0-24 h old) of C. cephalonica, after 48 h of exposure, complete inhibition in hatching was recorded in all the doses of peppermint (25, 50, 100 and 150 µl), 50, 100 and 150 µl of lemongrass and 150 µl of geranium.
