The larvicidal activities of essential oils from the leaves of Artemisia vulgaris L., Cymbopogon flexuosus (Nees ex Steud.) Wats. and Piper tuberculatum Jacq. were evaluated using third-instar larvae of Aedes aegypti. The essential oils were obtained by hydrodistillation and analyzed by GC and GC-MS. The essential oil of P. tuberculqatum had the lowest LC50 value (106.3 +/- 2.2 microg/mL), followed by that of A. vulgaris (114.1 +/- 1.7 microg/mL) and C. flexuosus (121.6 +/- 0.8 micro/mL). The results show that these essential oils may be potent sources of natural larvicides.
利用埃及伊蚊的三龄幼虫，对艾蒿、柠檬草和胡椒的叶片挥发油的杀幼虫活性进行了评估。挥发油通过水蒸馏法获得，并采用气相色谱（GC）和气相色谱-质谱联用（GC-MS）进行分析。胡椒挥发油的半数致死浓度（LC50）值最低（106.3±2.2微克/毫升），其次是艾蒿（114.1±1.7微克/毫升）和柠檬草（121.6±0.8微克/毫升）。结果表明，这些挥发油可能是天然杀幼虫剂的有效来源。
