Insecticidal Activity against Myzus persicae of Terpinyl Acetate and Bornyl Acetate in Thuja occidentalis Essential Oil

Essential oils have insecticidal activity against several insects and are composed of numerous compounds. This study investigated the effects Thuja occidentalis L. (Cupressaceae) essential oil, terpinyl acetate, bornyl acetate peach aphid [Myzus persicae (Sulzer)]. The effect on three Cupressaceae plants was highest in T. occidentalis. oil extracted by steam distillation, optimum conditions were found. GC-MS profiling components from leaves identified 16 volatile main α-thujone (16.58%), β-myrcene (14.62%), (9.31%), (8.52%). As a result metabolite plants, present large amounts all oils, they had an structure, so it estimated that activity. these two compounds stronger than other individual monoterpene addition surfactants to showed strong Terpinyl can be used as environmentally friendly insecticidal-active
