Insecticidal activity of ZnO NPs synthesized by green method using pomegranate peels extract on stored product insects

Green synthesis of nanomaterials is the most recent trend in nanotechnology since it takes into consideration sustainable development and waste recycling, produces high value materials. Furthermore, green excludes use or production toxic hazardous chemicals to environment. This work aimed zinc oxide nanoparticles (ZnO NPs) using pomegranate peels extract as a reducing capping reagent instead chemicals. Structural morphological characterization ZnO NPs was studied X-ray diffraction (XRD), Fourier Transform Infrared-Attenuated Total Reflection (FTIR-ATR), High-Resolution Transmission Electron Microscopy (HRTEM) Energy Dispersive X-Ray Spectroscopy (EDX). In addition application insecticide control two destructive stored product insect pests; rice weevil Sitophilus oryzae (L.) Angoumois grain moth Sitotroga cerealella (Olivier). The results XRD, FTIR-ATR EDX confirmed formation NPs. Also, XRD HRTEM affirmed that size synthesized have very small around 4nm. toxicity studies showed exhibited progressive increase mortality S. adults subjected treated wheat grains by increasing exposure intervals concentration. A post effect on progeny counts exposed 3 concentrations observed. Adherence body surface visualized Scanning (SEM). Images strong uptake massively attachment through different parts body. present suggests eco-friendly are promising pests.
