ABSTRACT
This chapter details the pesticidal activities of some genera, Lantana, Allium, Mentha, and Juniperus, are detailed. It discusses recent studies on essential oils of a wide range of plants are discussed. The chapter talks about a review conducted to evaluate the current research on using essential oils (EOs) as potential larvicides based on their chemical composition and biological efficacy. The selected plants were therefore required to meet two essential conditions: LC50 = 100 ppm and their chemical composition had to be known. Finally, special attention is given to Chinese herbs. In the screening program for new agrochemicals from Chinese medicinal herbs, Murraya exotica was found to possess insecticidal activity against the maize weevil, S. zeamais, and red flour beetle, T. Castaneum. The screening for bioactive principles from several Chinese medicinal herbs showed that the essential oil of Cymbopogon distans aerial parts possessed strong repellency against the booklouse, L. bostrychophila, and the red flour beetle, T. Castaneum.
