The larvicidal activity of essential oils (EOs) extracted from , and aromatic plants grown in Vietnam was evaluated on larvae. The EOs were hydro-distilled in a Clevenger-type apparatus. The EOs were analyzed by gas chromatography-mass spectrometry (GC-MS). The mortality rates obtained from the bioassays were used to calculate the lethal concentrations (LC) of the EOs by the probit analysis method. These essential oils exhibited toxicity to the larvae of . Results were obtained for (LC = 120.6 ppm), (LC = 38.8 ppm), (LC = 104.4 ppm), and (LC = 33.7 ppm). The essential oils of and were found to be the most efficient, and their respective values of LC were 33.7 ppm, 38.8 ppm. In conclusion, this research adds to the growing body of literature on natural larvicides from essential oils against mosquitoes.
对从越南种植的[植物名称1]、[植物名称2]和[植物名称3]等芳香植物中提取的香精油（EOs）针对[蚊虫名称]幼虫的杀幼虫活性进行了评估。这些香精油在克利夫兰型装置中进行水蒸馏。采用气相色谱 - 质谱联用仪（GC - MS）对香精油进行分析。通过生物测定获得的死亡率用于通过概率分析方法计算香精油的致死浓度（LC）。这些香精油对[蚊虫名称]幼虫表现出毒性。得到了[植物名称1]（LC = 120.6 ppm）、[植物名称2]（LC = 38.8 ppm）、[植物名称3]（LC = 104.4 ppm）和[植物名称4]（LC = 33.7 ppm）的结果。发现[植物名称4]和[植物名称2]的香精油效率最高，其各自的LC值分别为33.7 ppm、38.8 ppm。总之，本研究为关于香精油天然杀幼虫剂防治[蚊虫名称]蚊子的不断增长的文献增添了内容。
