Public concerns over synthetic pesticides have stimulated the search for alternative methods of control. Plant essential oils are the odorous components and secondary metabolites that can be separated from other plant tissues through steam distillation. Generally regarded as plant defenses against herbivory, they have demonstrated acute toxicity to various insect species and are of interest for the development of 'ecologically friendly' pesticides.

In the past, scientists have studied the specific herbivore-induced defense mechanisms, and found different responses might be induced by different insects. Based on the insect-plant coevolution ideas, different specialized herbivores might induce different plant defense. However, this concept has not been proved.
