Lesser grain borer, Rhyzopertha dominica (F), is reported as most destructive and major insect pest of various stored grain products including wheat. Present study was conducted to determine insecticidal and growth inhibition activities of essential oils extracted from peels of Citrus paradisi and Citrus reticulata against two strains of R. dominica adults under laboratory conditions. Twenty adults of R. dominica were exposed to the filter papers treated with citrus essential oils at

At concentration 12%, C. paradisi oil exhibited maximum mortality (49.00%) in Multan strain followed by C. paradisi in Vehari strain (40.66%), while C. reticulata (37.33%) and (30.00%) in Multan and Vehari strain respectively at exposure periods of 9 days. Adult mortality varied significantly with increase in concentration and due to the effect of Citrus species. R. dominica population buildup was minimum (5.74%) due to effect of C. paradisi after 120 days of treatment as compared to that of control treatment (21.667). Results exhibited that C. paradisi oil is most effective than C. reticulata oil for reducing the population of R. domonica. These results showed the potential usefulness of citrus oils for the management of R. dominica in flour mills, warehouses and food storage facilities.
