STUDY THE EFFECT OF Citrus aurantium LEAVES WATER EXTRACT COPER NANO PARTICLES ON THE 3th, 4th LARVAE AND PUPA OF Culex pipiens

Abstract

Our study is conducted to evaluate the effect of Citrus aurantium leaves coper nanoparticles.
Characterization of coper nanoparticles was performed using UV, FTIR. The diameter of coper
nanoparticles was distributed in the range of 2 to 12 nm. Using different concentration ֜s of
Citrus aurantium leaves extract, coper sulfate and nanoparticles (100, 200, 300ppm). The
result of our study showed that the higher concentration 300ppm of nanoparticles gave a higher
mortality percentage on 4th larvae 100% followed with 3th 89.3% and the pupa gave 83.3%
respectively, thus introduced to use Citrus aurantium leaves coper nano particles as a Culex
pipiens, management agent.
