In this work, we investigated insecticidal and repellent activities of the essential oils extracted from Ajania nitida and Ajania nematoloba against Tribolium castaneum and Lasioderma serricorne adults. The components of essential oils were analyzed by GC-MS. The main components of A. nitida oil were camphor (20.76%), thujone (18.64%), eucalyptol (13.42%), borneol (8.32%) and those of A. nematoloba oil were β-pinene (34.72%), eucalyptol (24.97%) and verbenol (20.39%). The results showed that the two essential oils possessed insecticidal and repellent activities against two species of insects. A. nitida oil possessed contact and fumigant toxicity against T. castaneum (LD = 30.10 µg/adult and LC = 21.07 mg/L air) and L.serricorne (LD = 17.51 µg/adult and LC = 11.23 mg/L air). A.nematoloba oil showed contact and fumigant toxicity against T. castaneum (LD = 102.29µg/adult and LC = 69.45 mg/L air) and contact toxicity against L.serricorne (LD = 53.43 µg/adult), but no obvious fumigant effect was observed against L.serricorne. Both of essential oils possessed strong repellent activity against T. castaneum and certain repellent activity against L.serricorne. Especially, A. nematoloba oil showed the same level percentage repellency as DEET(the positve control) against T. castaneum. The results indicated that the essential oils of A. nitida and A. nematoloba had the potential to be developed as natural insecticides and repellents for the control of T. castaneum and L.serricorne.
在本研究中，我们调查了从亮叶亚菊（Ajania nitida）和线叶亚菊（Ajania nematoloba）中提取的挥发油对赤拟谷盗（Tribolium castaneum）和烟草甲（Lasioderma serricorne）成虫的杀虫和驱避活性。采用气相色谱 - 质谱联用（GC - MS）分析挥发油的成分。亮叶亚菊挥发油的主要成分是樟脑（20.76%）、侧柏酮（18.64%）、桉叶油素（13.42%）、冰片（8.32%）；线叶亚菊挥发油的主要成分是β - 蒎烯（34.72%）、桉叶油素（24.97%）和马鞭草烯醇（20.39%）。结果表明，这两种挥发油对两种昆虫均具有杀虫和驱避活性。亮叶亚菊挥发油对赤拟谷盗具有触杀和熏蒸毒性（LD = 30.10 µg/成虫，LC = 21.07 mg/L空气）以及对烟草甲具有触杀和熏蒸毒性（LD = 17.51 µg/成虫，LC = 11.23 mg/L空气）。线叶亚菊挥发油对赤拟谷盗表现出触杀和熏蒸毒性（LD = 102.29 µg/成虫，LC = 69.45 mg/L空气）以及对烟草甲具有触杀毒性（LD = 53.43 µg/成虫），但对烟草甲未观察到明显的熏蒸效果。两种挥发油对赤拟谷盗均具有较强的驱避活性，对烟草甲具有一定的驱避活性。特别是，线叶亚菊挥发油对赤拟谷盗表现出与避蚊胺（阳性对照）相同水平的驱避率。结果表明，亮叶亚菊和线叶亚菊的挥发油有潜力被开发为用于防治赤拟谷盗和烟草甲的天然杀虫剂和驱避剂。
