The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae) is a major insect pest of vegetables such as okra.  While synthetic insecticides are vastly used to control aphis, extravagant application has led to resistance of insects and poses side effects on the predators. Consequently, essential oils (EOs) are the most effective, promising alternatives to synthetic insecticides. Field and lab experiments were therefore performed to study the impacts of some essential oils on aphids and their natural enemies. The essential oils (EOs) were ginger (Zingiber officinale), rosemary, (Salvia rosmarinus), basil, (Ocimum basilicum), clove (Syzygium aromaticum) and Simmondsia chinensis against Aphis gossypii and adult of the eleven-spotted lady beetle, Coccinella undecimpunctata. All essential oils were tested at concentrations of 1%, 3%, 5% in the field and 0.5%, 1.5%, 2.5% in the laboratory. The results revealed that  rosemary oil is considered the most potent oil among all tested oils against A. gossypii. Whereas clove oil is considered the least effective among the oils tested under the laboratory and field against A. gossypii. While ginger oil was the least toxic oil against C. undecimpunctata. These essential oils gave promising sources in controlling aphids and selectivity on C. undecimpunctata. through the results of this study, natural oils can be used to control aphids.
