摘　　要：The present study was conducted to evaluate the impact of bimetallic nanoparticles(NPs)of copper(Cu)and zinc(Zn)from Crotalaria longirostrata on the insect mortality and cell viability of Phenacoccus solenopsis.The biosynthesis of bimetallic nanoparticles(Cu/Zn-NPs)from C.longirostrata was confirmed by the presence of a single peak around 378 nm.The hydrodynamic diameter of the Cu/Zn nanoparticles varied from 59 to 119 nm and their zeta potential was found to be−30.90 mV.The EDX analysis showed a strong signal for Cu and Zn(8 and 8.6 keV,respectively).The Cu/Zn-NPs showed an effective insecticide activity against P.solenopsis with 63%of insect mortality after 96 h treatment.However,further studies about nanotoxicity of Cu/Zn-NPs from C.longirostra are needed to reveal the exact mechanism of nanoparticles toxicity in insects.
