摘要

蚊子对合成杀虫剂的抵抗力日益增强,因此需要生态友好的媒介控制替代品。本文研究了以水芹花提取物为原料绿色合成银纳米颗粒(Ag-NPs),并评价了其杀虫效果。quinquefasciatus,。和Ae。蚊。通过UV-Vis、FT-IR、XRD、SEM-EDX、TEM、Zeta电位和DLS等手段对合成的Ag-NPs进行了表征,其LC50值分别为6.501、20.875和22.649 ppm,具有较强的杀虫和杀虫活性。处理后的幼虫的形态和组织病理学改变,以及抗氧化(SOD, GPx)和解毒(GST, AChE)酶的显著调节,表明氧化应激是一个关键的作用模式。重要的是,生物安全测试显示对青蒿素的毒性很小,突出了这些Ag-NPs的生态兼容性。该研究展示了一种创新的植物基纳米杀虫剂,具有很强的可持续蚊虫控制潜力,解决了杀虫剂抗性和环境毒性的挑战。

Eco-Friendly Synthesis of Silver Nanoparticles and Its Larvicidal Property Against Malaria, Filariasis, and Dengue Vectors

The increasing resistance of mosquitoes to synthetic pesticides necessitates eco-friendly alternatives for vector control. This study presents the green synthesis of silver nanoparticles (Ag-NPs) using Aerva lanata flower extract and evaluates their larvicidal efficacy against Cx. quinquefasciatus, An. stephensi, and Ae. aegypti. The biosynthesized Ag-NPs, characterized by UV–Vis, FT-IR, XRD, SEM–EDX, TEM, Zeta potential, and DLS analyses, exhibited potent larvicidal and pupicidal activities, with LC50 values of 6.501, 20.875, and 22.649 ppm, respectively. The morphological and histopathological alterations in treated larvae, alongside significant modulation of antioxidant (SOD, GPx) and detoxification (GST, AChE) enzymes, indicate oxidative stress as a key mode of action. Importantly, biosafety tests revealed minimal toxicity to Artemia salina, highlighting the eco-compatibility of these Ag-NPs. This study demonstrates an innovative, plant-based nanobiopesticide with strong potential for sustainable mosquito control, addressing the challenges of insecticide resistance and environmental toxicity.

期刊介绍: Luminescence provides a forum for the publication of original scientific papers, short communications, technical notes and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence and phosphorescence. Luminescence publishes papers on assays and analytical methods, instrumentation, mechanistic and synthetic studies, basic biology and chemistry. Luminescence also publishes details of forthcoming meetings, information on new products, and book reviews. A special feature of the Journal is surveys of the recent literature on selected topics in luminescence.
