This study aims to determine the composition of the essential oil of Pistacia lentiscus leaves by gas chromatographymass spectrometry (GC/MS) and to test its insecticidal activity against the larvae of Aphis spiraecola, which represents a serious threat to citrus production and cause most economic loss for the citrus culture. The essential oil of lentisk leaves was isolated by hydrodistillation using a Clevenger-type, the chemical composition was determined by GC/MS. The insecticidal activity of essential oil was determined by using the contact method against A. spiraecola larvae. A total of 74 compounds were identified, corresponding to chromatographic peaks representing 89.6% of the total area of all peaks. The most abundant compounds were monoterpene hydrocarbons (54.2%) with 8.8% p-cymene and 7.2% a-pinene. The insecticidal assay revealed an interesting insecticidal activity against the larvae of A. spiraecola with an LD50 of 0.2 µL. This study introduces and supports the use of the essential oil of P. lentiscus as a biopesticide and open new ways for its future exploitation in phytosanitary industries. [ABSTRACT FROM AUTHOR] |
