Mosquitoes, being a vector for some potentially dreadful diseases, pose a considerable threat to people all around the world. The control over the growth and propagation of mosquitoes comprises conventional pesticides, insect growth regulators and other microbial control agents. However, the usage of these common chemicals and conventional pesticides eventually has a negative impact on human health as well as the environment, which therefore becomes a major concern. The lacuna allows nanotechnology to come into action and exploit nanopesticides. Nanopesticides are majorly divided into two categories-synthetic and biological. Several nanoformulations serve as a promising nanopesticide viz. nanoparticles, e.g. biologically synthesised nanoparticles through plant extracts, nanoemulsions prepared using the essential oils like neem oil and citronella oil and nanoemulsion of conventional pesticides like pyrethroids. These green approaches of synthesising nanopesticides make use of non-toxic and biologically derived compounds and hence are eco-friendly with a better target specificity. Even though there are numerous evidences to show the effectiveness of these nanopesticides, very few efforts have been made to study the possible non-target effects on other organisms prevalent in the aquatic ecosystem. This study focuses on the role of these nanopesticides towards the vector control and its eco-safe property against the other non-target species.
蚊子作为一些潜在可怕疾病的传播媒介，对世界各地的人们构成了相当大的威胁。控制蚊子的生长和繁殖包括使用传统杀虫剂、昆虫生长调节剂和其他微生物控制剂。然而，这些常见化学物质和传统杀虫剂的使用最终会对人类健康和环境产生负面影响，因此成为一个主要关注点。这一空白使得纳米技术得以发挥作用并利用纳米农药。纳米农药主要分为合成和生物两类。几种纳米制剂被用作有前途的纳米农药，例如纳米颗粒，例如通过植物提取物合成的生物纳米颗粒、使用印楝油和香茅油等精油制备的纳米乳液以及拟除虫菊酯等常规农药的纳米乳液。这些合成纳米农药的绿色方法利用了无毒和生物衍生的化合物，因此对环境友好，具有更好的目标特异性。尽管有大量证据表明这些纳米农药的有效性，但很少有人努力研究它们对水生生态系统中普遍存在的其他非目标生物的可能非目标影响。本研究重点研究了这些纳米农药在控制病媒方面的作用及其对其他非目标物种的生态安全性。
