Six essential oils from Morrocan plants belonging to different botanical families (Lamiaceae, Pinaceae and Verbenaceae), were prepared by hydrodistillation. These essential oils from Morrocan plants, which have a long tradition in adjuvant therapy, were tested for insecticidal activity by the method of microcomputer-atmosphere against three major pests of stored products : Rhyzopertha dominica (F), Sitophilus oryzae (L) and Tribolium castaneum (herbst). The results obtained showed that the essential oils possessed highly significant insecticidal properties against the pests studied. R (+) pulegone, a monoterpene ketone and a major component of the essential oil of Mentha pulegium exhibited the highest insecticidal activity.
