Insecticidal Effect of Pistacia lentiscus (Anacardiaceae) Metabolites against Lobesia botrana (Lepidoptera: Tortricidae)

The extensive use of synthetic insecticides in agriculture poses a great risk for human health and the ecosystem, mandates development safer alternatives derived from natural products. In present study, we assessed larvicidal effect Pistacia lentiscus fruits, leaves, bark extracts their components on larvae major vine pest, Lobesia botrana. is an evergreen shrub or small tree possessing significant medicinal value with numerous therapeutic uses since antiquity. Using petri dish residual exposure topical application bioassays demonstrated that fruit extract P. its metabolites were toxic L. botrana larvae. Extracts leaves showed no effect. ?ioassay-guided fractionation hexane led to identification constituents insecticidal properties Specifically, have identified main contributor bioactivity fruits fraction, PLFHe2 (76.25%). Furthermore, found mixture triglycerides fatty acids responsible observed toxicity are oleic linoleic acid.
