Economic damages caused by pest infestation during storage is a major problem in developed and developing countries. Synthetic pesticides have been mainly used to control stored product pests since 1960. Nowadays, appearance of resistance and human health’s risks underline the alternative research needs. Plants essentials oils are recognized as a safe alternative for insecticide applications.The present study was conducted to investigate the insecticidal activity of a number of essential oils from cultivated aromatic plants and their combinations against Tribolium castaneum.Three essential oils and their mixtures were evaluated by fumigation and repellent effectiveness tests against Tribolium castaneum. Bioassays indicated that M. longifolia EO has the most important insecticidal potential as fumigant and repellent. Our results indicated that fumigant and repellent activities of essential oils mixtures can be improved by synergistic and Additive effect. Whereas, some combination exhibited a low insect mortality and repellency regenerated by the antagonistic effect. In our study we underlined the insecticide potential of the essential oils mixture but other studies should be elaborated for a new pesticide elaboration.
