In this study, Noot and Chalermglin (Magnoliaceae) essential oil (MCEO) was evaluated for insecticidal activity against the yellow fever mosquito and attractant activity for the Mediterranean fruit fly . The leaves of (Giổi chanh) were collected from northwestern Vietnam, and the water-distilled MCEO was analyzed by gas-chromatography and mass spectrometry (GC-MS). The major constituents of MCEO were identified as linalool 19%, geranial 16%, citronellal 14%, neral 14%, and sabinene 12%. MCEO showed 100% mortality at 1 μg/μL against 1st instar larvae of (Orlando strain, ORL), and the oil exhibited 54% (ORL) and 68% (Puerto Rico strain) mortality at 5 μg/mosquito against adult females. Initial screens showed that MCEO had weak insecticidal activity compared to the positive control permethrin. In bioassays with sterile male , MCEO exhibited moderately strong attraction, comparable to that observed with a positive control, essential oil (TREO). Herein, the insecticidal and attractant activities of MCEO are reported for the first time.
在这项研究中，评估了八角茴香（木兰科）精油（MCEO）对黄热病蚊子的杀虫活性和对地中海实蝇的引诱活性。（Giổi chanh）的叶子从越南北部采集，用水蒸馏法得到的 MCEO 通过气相色谱和质谱联用仪（GC-MS）进行分析。MCEO 的主要成分被鉴定为芳樟醇 19%、橙花醛 16%、香茅醛 14%、柠檬醛 14%和柠檬烯 12%。MCEO 在 1 μg/μL 时对 1 龄幼虫（Orlando 株，ORL）的死亡率为 100%，而在 5 μg/只时对成蚊的死亡率为 54%（ORL）和 68%（波多黎各株）。初步筛选表明，与阳性对照氯菊酯相比，MCEO 的杀虫活性较弱。在无菌雄虫的生物测定中，MCEO 表现出中度强的吸引力，与观察到的阳性对照，即香精油（TREO）相当。在此，首次报道了 MCEO 的杀虫和引诱活性。
