In this study essential oil was tested on major mosquito species and toxicity was compared with temephos. Mortality was calculated after 24 h and 48 h post treatment. In 24 h treatment essential oil show strong larvicidal activity with LC and LC values were 30.198ppm, 103.389ppm for 13.578ppm, 106.755ppm for ; and, 7.469ppm, 32.454ppm for and 48 h post treatment LC and LC values were, 12.576, 49.380ppm for 7.926, 34.470ppm for and 4.408, 21.048ppm for . Chemical composition of essential oil using GC-MS and FT-IR analysis shows the presence of 1,8-cineol, (71.7%); α-pinene, (9.14%) as a major compounds. Our findings suggest that essential oil from leaves can be used for control of mosquito larvae.
在这项研究中，精油被测试于主要的蚊子物种，其毒性与涕灭威进行了比较。处理后 24 小时和 48 小时计算死亡率。在 24 小时的处理中，精油表现出强烈的杀幼虫活性，LC 和 LC 值分别为 30.198ppm、103.389ppm 用于 13.578ppm、106.755ppm 用于 和 7.469ppm、32.454ppm 用于 ，而在 48 小时的处理中 LC 和 LC 值分别为 12.576、49.380ppm 用于 7.926、34.470ppm 用于 和 4.408、21.048ppm 用于 。使用 GC-MS 和 FT-IR 分析的精油化学成分表明存在 1,8-桉叶油醇（71.7%）；α-蒎烯（9.14%）为主要化合物。我们的研究结果表明，来自 叶子的精油可用于控制蚊子幼虫。
