•A new synthetic route to narrow disperse copper oxide nanoparticles is described.•Punica granatum leaves extract acts as reducing and stabilizing agent in synthesis at room temperature.•Copper oxide nanoparticles showed mortality of Aphid 1st, 2nd, 3rd and 4th nymphal instars by 86% compared with control.
Copper oxide nanoparticles (CuONPs) were synthesized by a simple and green method using Punica granatum peels extract at room temperature. Biosynthesized copper oxide nanoparticles were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), UV–vis absorption spectroscopy, and X-ray diffraction (XRD). The particles are crystalline in nature with average size 40 nm. The morphology of the copper oxide nanoparticles could be controlled by tuning the amount of Punica granatum peels aqueous extract and copper ions. This study determined the mortality efficacy of the synthesized CuONPs against green peach Aphid.
