There is a growing need to use green and efficient larvicidal as alternatives for conventional chemicals in vector control programs. Nanotechnology has provided a promising approach for research and development of new larvicides. Larvicidal potential of a nanoemulsion of essential oil reports against .
The nanoemulsion of was formulated in various ratios comprising of oil, tween 80, span 20 and water by stirrer. It was characterized by transmission electron microscopy (TEM) and dynamic light scattering (DLS). All components of essential oil were identified by GC-MS analysis. The larvicidal potential of the oil and its nanoformulation were evaluated against larvae of . The stability and durability of nanoemulsion was observed over a period of time.
Sixty one components in the oil were identified, cinnamaldehyde (56.803%) was the main component. The LC and LC values of essential oil were calculated as 49 ppm and 37 ppm, respectively. The nanoemulsion droplets were found spherical in shape. It was able to kill 100% of larvae in up to 3 days. It was stable after dilution and increased its larvicidal activity up to 32% compared with the essential oil.
A novel larvicide based on nanotechnology introduced. This experiment clearly showed increasing larvicidal activity and residual effect of the nanoformulation in comparison with the bulk essential oil. It could be concluded that this nanoemulsion may be considered as safe larvicide and should be subject of more research in this field.
在病媒控制项目中，越来越需要使用绿色高效的杀幼虫剂来替代传统化学品。纳米技术为新型杀幼虫剂的研发提供了一种有前景的方法。已有关于某种精油纳米乳液杀幼虫潜力的报道。
通过搅拌器以不同比例配制包含油、吐温80、司盘20和水的该精油纳米乳液。通过透射电子显微镜（TEM）和动态光散射（DLS）对其进行表征。通过气相色谱 - 质谱联用（GC - MS）分析确定该精油的所有成分。评估该精油及其纳米制剂对[具体蚊虫种类]幼虫的杀幼虫潜力。在一段时间内观察纳米乳液的稳定性和耐久性。
鉴定出该精油中的61种成分，肉桂醛（56.803%）为主要成分。该精油的LC₅₀和LC₉₀值分别计算为49 ppm和37 ppm。发现纳米乳液滴呈球形。它能够在长达3天内杀死100%的幼虫。稀释后它很稳定，与精油相比其杀幼虫活性提高了32%。
引入了一种基于纳米技术的新型杀幼虫剂。该实验清楚地表明，与纯精油相比，纳米制剂的杀幼虫活性和残留效果有所提高。可以得出结论，这种纳米乳液可被视为安全的杀幼虫剂，应在该领域进行更多研究。
