Essential oils (EOs) of Achillea millefolium, Myrtus communis, Rosmarinus officinalis, Helichrysum italicum, Foeniculum vulgare and Lavandula angustifolia were analysed by GC FID and GC-MS in order to define their aromatic profiles and then to evaluate their toxicity and repellent activity against Sitophilus zeamais Motsch. (Coleoptera Dryophtoridae). Results from topical applications on insects showed that all EOs had more or less marked insecticidal activity. However, the mortality rate never exceeded the 76% value. Results of repellency tests, showed that M. communis and L. angustifolia EOs showed the highest repellency to S. zeamais adults.

Abstract
Essential oils (EOs) of Achillea millefolium, Myrtus communis, Rosmarinus officinalis, Helichrysum italicum, Foeniculum vulgare and Lavandula angustifolia were analysed by GC FID and GC-MS in order to define their aromatic profiles and then to evaluate their toxicity and repellent activity against Sitophilus zeamais Motsch. (Coleoptera Dryophtoridae). Results from topical applications on insects showed that all EOs had more or less marked insecticidal activity. However, the mortality rate never exceeded the 76% value. Results of repellency tests, showed that M. communis and L. angustifolia EOs showed the highest repellency to S. zeamais adults.
