Larvicidal activity of essential oils derived from 11 aromatic medicinal plants against early 4th-stage larvae of Aedes aegypti and Culex pipiens pallens was tested in the laboratory. At 100 ppm, the essential oils of all plants caused 100% mortality against Ae. aegypti and Cx. pipiens pallens. At 25 ppm, the essential oils of Citrus bergamia, Cuminum myrrha, and Pimenta racemosa caused 100% mortality against larvae of Ae. aegypti and Cx. pipiens pallens. The oil of C. begamia caused 32.5% and 24.5% mortality against Ae. aegypti and Cx. pipiens pallens at 12.5 ppm, but 24.2% and 0% mortality against Ae. aegypti and Cx. pipiens pallens at 6.25 ppm, respectively. The oil of P. racemosa caused 52.3% and 38.5% mortality against Ae. aegypti and Cx. pipiens pallens at 12.5 ppm, but 32.2% and 0% mortality against Ae. aegypti and Cx. pipiens pallens at 6.25 ppm, respectively. The larvicidal activity of oils of C. bergamia, C. myrrha, and P. racemosa was significantly reduced when used at 6.25 ppm. These plants warrant further studies as possible agents for mosquito control.
在实验室中测试了11种芳香药用植物的精油对埃及伊蚊和淡色库蚊四龄初期幼虫的杀幼虫活性。在100 ppm时，所有植物的精油对埃及伊蚊和淡色库蚊均导致100%的死亡率。在25 ppm时，香柠檬、没药小茴香和多香果的精油对埃及伊蚊和淡色库蚊幼虫导致100%的死亡率。在12.5 ppm时，香柠檬精油对埃及伊蚊和淡色库蚊的死亡率分别为32.5%和24.5%，但在6.25 ppm时，对埃及伊蚊和淡色库蚊的死亡率分别为24.2%和0%。在12.5 ppm时，多香果精油对埃及伊蚊和淡色库蚊的死亡率分别为52.3%和38.5%，但在6.25 ppm时，对埃及伊蚊和淡色库蚊的死亡率分别为32.2%和0%。当在6.25 ppm使用时，香柠檬、没药和多香果精油的杀幼虫活性显著降低。这些植物作为可能的蚊虫控制剂值得进一步研究。
