Mosquitoes, in addition to being a biting nuisance, are vectors of several pathogenic viruses and parasites. As a continuation of our work identifying abundant and/or invasive plant species in Vietnam for use as ecologically friendly pesticidal agents, we obtained the essential oils of , , , , and ; analyzed the essential oils using gas chromatographic techniques; and screened the essential oils for mosquito larvicidal activity against and . The most active larvicidal essential oils were , which was rich in thymohydroquinone dimethyl ether (29.4%), ()-β-caryophyllene (19.7%), α-pinene (8.8%), germacrene D (7.8%), and α-humulene (4.3%), (24-h LC 23.4 and 29.1 μg/mL) on and , respectively, and , dominated by 1-undecene (41.9%) and germacrene D (11.0%), (24-h LC 30.1 and 29.6 μg/mL) on the two mosquito species. The essential oils of and were also active against mosquito larvae. Notably, , , and essential oils were not toxic to the non-target water bug, . However, essential oil showed insecticidal activity (24-h LC 48.1 μg/mL) on . Based on these results, , , and essential oils appear promising for further investigations.
蚊子不仅叮人，还是几种致病病毒和寄生虫的传播媒介。作为我们识别越南丰富和/或入侵植物物种并将其用作生态友好型杀虫剂工作的延续，我们获得了、、、、和的精油；使用气相色谱技术分析了精油；并筛选了精油对和的杀蚊幼虫活性。最具活性的杀蚊幼虫精油是，其富含百里香氢醌二甲醚（29.4%）、()-β-石竹烯（19.7%）、α-蒎烯（8.8%）、大根香叶烯 D（7.8%）和α-葎草烯（4.3%），对和的 24 小时 LC 23.4 和 29.1 μg/mL），而由 1-十一烯（41.9%）和大根香叶烯 D（11.0%）主导的，则对这两种蚊子的 24 小时 LC 30.1 和 29.6 μg/mL）。和的精油对蚊子幼虫也有活性。值得注意的是，、、和的精油对非靶标水龟虫无毒性。然而，精油对表现出杀虫活性（24 小时 LC 48.1 μg/mL）。基于这些结果，、、和的精油似乎有进一步研究的前景。
