| dc.description.abstract | Aromatic plants have broad-spectrum applications in many life aspects and possess rich volatile essential oil components. Pure essential oils have been divided into two groups as hydrocarbons and oxygenated on the basis of their chemical constitutions. These essential oils are being applied against many insects and pests as an alternative approach. In this review, the most effective essential oil components that possess pesticidal activity via fumigant, contact, or ingestion on storage pests are discussed. Moreover, the effective components possessing repellent and feeding deterrent activities, and cause development, reproductive, and physiological inhibition, especially on stored-product pest insects are highlighted. Although there are many effective ingredients, some components such as eucalyptol, camphor, linalool, eugenol, limonene, terpinen-4-ol, menthone, and anethole have the most effective and competitive activities when compared with some synthetic chemicals in terms of insecticidal activity in fumigant and contact toxicity tests. Similarly, components such as eugenol, eucalyptol, anethole, camphor, and linalool have displayed significant repellent activity against storage pests. Moreover, components such as limonene, linalool, eugenol, isoeugenol, methyleugenol, and sparteine have caused significant feeding deterrence on stored-product insect pests. Besides, some components such as eucalyptol, eugenol, camphor, isoeugenol, methyleugenol, ?-pinene, ?-caryophyllene, limonene, ?-bisabolol, linalool, terpinen-4-ol, and geraniol have prevented the development stages and decreased the life span of stored-product pests. Components such as eucalyptol, eugenol, camphor, anethole, ?-pinene, ?-caryophyllene, limonene, and linalool displayed a significant reduction in the productivity of stored-product pests. Some components of essential oils have also been evaluated for their modes of action. Keeping in view the importance of these pure components of essential oils against stored-product pests, we have summarized the most significant studies as a review paper on this aspect.
