Essential oils from aerial parts of the herbs and , and leaves of the tree were analyzed by GC-FID and GC-MS, and their larvicidal activities were assayed on the early fourth instar larvae of . The major constituents of the oils were limonene (14.5%) and thymol (11.5%) in , thymol (46.5%), 4aα,7α,7aβ-nepetalactone (18.3%) and 4aα,7β,7aα-neptalactone (19.7%) in , eugenol (14.5%) andγ-eudesmol (9.5%) in .The oil of had a strong larvicidal activity (LC < 50 µg/mL; LC < 86.8 µg/mL) on while the remaining oils showed a moderated killing effect. The larvicidal activity of oil was associated to the contents of 1,8-cineol, camphor, 4aα,7α,7aβ-Nepetalactone, 4aα,7β,7aα-Nepetalactone and thymol. Our results indicate that the oil of deserves to be used as a source of larvicidal agents against .
采用气相色谱 - 氢火焰离子化检测器（GC - FID）和气相色谱 - 质谱联用仪（GC - MS）对草本植物地上部分以及树木叶片的精油进行了分析，并对致倦库蚊（Culex pipiens quinquefasciatus）的四龄初期幼虫进行了杀幼虫活性测定。在[植物名称1]的精油中，主要成分是柠檬烯（14.5%）和百里香酚（11.5%）；在[植物名称2]的精油中，百里香酚（46.5%）、4aα,7α,7aβ - 荆芥内酯（18.3%）和4aα,7β,7aα - 荆芥内酯（19.7%）；在[植物名称3]的精油中，丁香酚（14.5%）和γ - 桉叶醇（9.5%）。[植物名称1]的精油对致倦库蚊具有很强的杀幼虫活性（LC₅₀ < 50 μg/mL；LC₉₀ < 86.8 μg/mL），而其余精油表现出中等的杀灭效果。[植物名称1]精油的杀幼虫活性与1,8 - 桉叶素、樟脑、4aα,7α,7aβ - 荆芥内酯、4aα,7β,7aα - 荆芥内酯和百里香酚的含量有关。我们的结果表明，[植物名称1]的精油值得作为一种针对致倦库蚊的杀幼虫剂来源。
