In this study Pergularia daemia unripe fruits were used to synthesize zinc oxide nanoparticles (Pd-ZnONPs). UV-vis Spectroscopy detected the production of ZnONPs. XRD, FTIR, SEM, and TEM studies were used to characterize the synthesized Pd-ZnONPs. Aedes aegypti (Ae. aegypti) third instar larvae were analyzed to diverse concentrations of Pd-unripe fruit extract and Pd-ZnONPs for 24 hours to assess the larvicidal effect. Mortality was also detected in Ae. aegypti larvae under laboratory conditions, with corresponding LC and LC values of 11.11 and 21.20 µg/ml respectively. As a result of this study, the levels of total proteins, esterases, acetylcholine esterase, and phosphatase enzymes in the third instar larvae of Ae. aegypti were significantly lower than the control. These findings suggest that Pd-ZnONPs could be used to suppress mosquito larval populations.
在这项研究中，使用 Pergularia daemia 未成熟果实来合成氧化锌纳米粒子（Pd-ZnONPs）。紫外可见光谱检测到 ZnONPs 的产生。XRD、FTIR、SEM 和 TEM 研究用于表征合成的 Pd-ZnONPs。用不同浓度的 Pd-未成熟果实提取物和 Pd-ZnONPs 处理埃及伊蚊（Aedes aegypti）三龄幼虫 24 小时，评估其杀幼虫效果。在实验室条件下还检测到埃及伊蚊幼虫的死亡率，LC 和 LC 值分别为 11.11 和 21.20 µg/ml。因此，本研究表明，Pd-ZnONPs 可用于抑制蚊虫幼虫种群。
