Repellent Activity of Plant Derived Essential Oils against Sitophilous oryzae (Linnaeus) and Tribolium castaneum (Herbst)

Bhuwan Bhaskar Mishra and S.P. Tripathi
Several species of insect pests are known for attacking granaries and other food products since time immemorial. Sitophilous oryzae and Tribolium castaneum are major pests of stored grains including grains, flour, peas, nuts, dried fruits, spices etc. Use of synthetic pesticide for the management of these insect pest cause great hazards for environment and toxic to non-target livings. In the present investigation, in search of replacement of these synthetic pesticides, essential oils of Bael (Aegle marmelos), Dhaniya (Corriandrum sativum), Laung (Schyzygium aromaticum) and Orange (Citrus reticulata) were evaluated for their repellent activity against S. oryzae and T. castenium. For repellency assays, different solutions of each essential oil were prepared in acetone and applied on half of the filter paper. The other half of the filter paper was treated with acetone only. Ten adults of insects were released at the centre of the each petri dish having treated and untreated filter paper and after 4 h. insect number in treated and untreated halves were noted. Highest repellent activity was observed for S. aromaticum essential oil against T. castaneum (90%) and S. oryzae are (90%),whereas, C. reticulata essential oil showed minimum repellent activity against these two insect pests (78 and 80%), respectively.
