Abstract

The application of leaf extract to synthesize nanoparticles has been taken as a green method. In this study, the potential for synthesizing zinc oxide nanoparticles (ZnO NPs) from Clausena anisata Hook.f. ex Benth. leaf extract was investigated. The source of zinc was zinc nitrate hexahydrate (Zn(NO3)2.6H2O). The characterization study was done by Ultraviolet–visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), Transmission electron microscope (TEM) and atomic force microscopy (AFM). The crystalline shape of nanoparticles is disclosed inside the XRD result, morphology is confirmed through SEM effects, and consequently, the ZnO NPs scale was predicted. ZnO NPs were synthesized to work against Sitophilus zeamais adults. A mortality count was carried out in 14 days and all the 3 dosages (0.2 g, 0.4 g and 0.6 g) were effective in killing S. zeamais. F1 progeny emergence was highly reduced in comparison to untreated control. Maize seeds were successfully germinated after treatment application with ZnO NPs.

使用 Clausena anisata Hook.f. ex Benth(ulmaayii) 叶提取物合成的氧化锌纳米粒子对玉米象鼻虫（鞘翅目：虫科）的昆虫毒性研究

利用叶提取物合成纳米颗粒被认为是一种绿色的方法。在本研究中，研究了以山葵为原料合成氧化锌纳米粒子(ZnO NPs)的潜力。Benth交货。对叶提取物进行了研究。锌的来源为六水硝酸锌(Zn(NO3)2.6H2O)。采用紫外可见光谱(UV-Vis)、x射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)和原子力显微镜(AFM)对其进行了表征。XRD结果揭示了纳米颗粒的晶体形状，SEM结果证实了纳米颗粒的形貌，并对ZnO纳米粒子的尺度进行了预测。合成了氧化锌NPs对玉米象成虫的杀伤作用。14 d后进行死亡计数，0.2 g、0.4 g和0.6 g 3种剂量均能有效杀灭玉米玉米蚜。与未经处理的对照相比，F1后代的羽化程度大大降低。施氧化锌NPs处理后，玉米种子成功发芽。
