摘要：The synthesis of nanomaterials of copper oxide (CuO), zinc oxide (ZnO), magnesium hydroxide (MgOH) and magnesium oxide (MgO) is considered to be a successful way of synthesis by using aqueous extracts of Punicagrantum peels, Olea europea leaves and Chamaemelumnobile flowers from copper sulfate, zinc sulfate and magnesium sulfate. The synthesized nanoparticles were characterized by UV-visible spectroscopy (UV-vis), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM) and fourier transform infrared spectroscopy (FT-IR). SEM and TEM analysis showed that the particles were spherical and the size of the particles ranged from 5 nm to 80 nm. The screening of synthesized bio-nanoparticles revealed that these nanoparticles were effective in increasing the mortality percent of green peach aphid,Myzu spersicae Sulzer (Homoptera :Aphididae). From this study, it is concluded that the biosynthesized metal oxide nanoparticles had controlled thegreen peach aphid. Magnesium hydroxide bionanoparticles synthesized were the best control to M.persicae compared to other synthetic nanoparticles. Hence, it might be the best against M. persicae environmentally.
