Biopesticidal Potential of Some Plant Derived Essential Oils against the Stored Grain Pests
Journal Title: International Journal of Zoological Investigations - Year 2017, Vol 3, Issue 2
Abstract
Chemical control of insects is an effective strategy used extensively in daily life. However, the widespread use of synthetic insecticides has led to many negative consequences, resulting in increasing attention to natural products. Among the alternative strategies, the use of plants’ insecticidal allelochemicals appears to be promising. Aromatic plants and their essential oils are among the most efficient botanicals. The present study was aimed to evaluate the biopesticidal potential of five plant-derived essential oils --mint (Mentha arvensis), ajwain (Carum capticum), lemongrass (Cymbopogon citrates), clove (Syzygium aromaticum) and eucalyptus (Eucalyptus globulas]) against three stored grain pest species namely Tribolium castaneum, Oryzaephilus surinamensis and Rhyzopertha dominica. A significant dose-dependent insecticidal effect was observed for all the essential oils, however, preference for oils was found to be different for each species. The results suggest the ability of using these essential oils for stored grain pest infestation as a safe alternative to insecticides.
