Bioactivities of the Leaf Essential Oil of Curcuma Longa (Var. Ch-66) On Three Species of Stored-Product Beetles (Coleoptera) A. K. Tripathi, V. Prajapati, N. Verma, J. R. Bahl, R. P. Bansal, S.P.S. Khanuja, and S. Kumar Central Institute of Medicinal and Aromatic Plants, P.O. CIMAP, Lucknow-15, India
Essential oil extracted from the leaves of turmeric, Curcuma longa L., was investigated for contact and fumigant toxicity and its effect on progeny production in three stored-product beetles, Rhyzopertha dominica F. (lesser grain borer), Sitophilus oryzae L. (rice weevil), and Tribolium castaneum Herbst (red flour beetle). Oviposition-deterrent and ovicidal actions of C. longa leaf oil were also evaluated against T. castaneum. The oil was insecticidal in both contact and fumigant toxicity assays. The adults of R. dominica were highly susceptible to contact action of C. longa leaf oil, with LD value of 50
36.71 µg/mg weight of insect, whereas in the fumigant assay, adults of S. oryzae were highly susceptible with LC value of 11.36 mg/liter air.

Further, in T. castaneum, the C. longa oil reduced oviposition and egg hatching by 72 and 80%, 2
respectively at the concentration of 5.2 mg/cm . At the concentration of 40.5 mg/g food, the oil totally suppressed progeny production of all the three test insects. Nutritional indices indicate >81% antifeedant action of the oil against R. dominica, S. oryzae and T. castaneum at the highest concentration tested.
