Comparative Study Between of the Effect of Biologically Prepared of two Types of Silver Nanoparticles and Nanoscale in Anti-Mosquito Culex.Pipienes

Abstract

The study addressed the influences of bio-prepared silver nanoscale from Verticillium lecanii mushrooms and nanoscale silver prepared from Peganum harmala L sand extract in the fight against C.pipienes mosquitoes, The concentrations used for the bio-prepared Nano-silver from the fungus were 5.2,5, 5.7.10 ml, and the lowest killing rate was 3.3% at a concentration of 5.2 after 48 hours of treatment, While the highest murder rate was 3.5% in concentration10 and 48 hours after treatment compared to the control treatment in which the murder rate did not occur. As for the nano-silver ether biologically prepared from the Harmet extract in mosquito control, the concentrations used were 25.0, 50. 0,75. 0 ml The lowest killing rate was 3.3% in the concentration of 25.0 after 48 hours of treatment, while the highest killing rate was 0.8% in the concentration of 75.0 after 48 hours of treatment compared to the control treatment in which the murder rate did not occur.
