Aedes aegypti and Aedes albopictus are the key transmitters of varied life-threatening arbovirus diseases; overuse of synthetic chemicals to target vector-borne diseases has an adverse impact on the environment. Biological agents have proven to be an alternative source to synthetic agents for controlling mosquitoes. In this context, the present study investigated the biosynthesis of ZnO NPs using Solanum lycopersicum leaf extract under the influence of solution combustion synthesis method and assessment of its larvicidal efficacy against Aedes aegypti. Synthesised ZnO NPs were characterised by using UV–vis, FTIR, SEM, EDX and XRD. The physicochemical parameter confirmed the synthesised nanoparticles were highly pure. The UV spectrum showed a strong peak at 352 nm corresponding to bandgap energy 3.01 eV. The SEM indicates the particles were rod-like structures. Further, the EDX analysis primarily confirms the zinc and oxygen without any impurities. The XRD data shows the crystallite size of ZnO Nps was of 40.93 nm. Finally, the aqueous leaf extract and ZnO NPs showed significant (p<0.05) larvicidal activity at 48 h. However, ZnO NPs revealed high larvicidal effect compared to aqueous extract. From the results, it can be concluded that the bioactive constituents present within the plant extract act as capping and reducing agents for the successful ZnO NPs synthesis and could be used for controlling mosquito vector Ae. aegypti.

埃及伊蚊和白纹伊蚊是各种威胁生命的虫媒病毒疾病的主要传播者；针对病媒传播疾病过度使用合成化学品对环境产生不利影响。生物制剂已被证明是控制蚊子的合成制剂的替代来源。在此背景下，本研究调查了在溶液燃烧合成方法的影响下使用番茄叶提取物生物合成 ZnO NPs并评估其对埃及伊蚊的杀幼虫效果。. 合成的 ZnO NPs 使用 UV-vis、FTIR、SEM、EDX 和 XRD 进行表征。理化参数证实合成的纳米颗粒是高纯度的。紫外光谱在 352 nm 处显示出一个强峰，对应于 3.01 eV 的带隙能量。SEM表明颗粒为棒状结构。此外，EDX 分析主要证实了不含任何杂质的锌和氧。XRD 数据显示 ZnO Nps 的微晶尺寸为 40.93 nm。最后，水叶提取物和 ZnO NPs 在 48 小时时显示出显着的（p<0.05）杀幼虫活性。然而，与水提取物相比，ZnO NPs 显示出较高的杀幼虫效果。从结果来看，艾。埃及人。
