BIOCONTROL EFFICACY OF BACTERIAL SYNTHESIS SILVER NANOPARTICLES ON INSECT PEST HYLOPTERUS PRUNI

Nanotechnology has

become one of the most promising new approaches for pest control in the recent

years and is expected to revolutionize the field of pest management in the near

future. Nanoparticles can be used as effective pesticides against weeds, plant

pathogens, and insect pests and may also be incorporated into new formulations

of insecticides and insect repellents. The biosynthesis of nanoparticles using bacteria has attracted much

researcher interest because of its intrinsic qualities and potential

applications in different fields. Bacterial synthesis of nanoparticles

is a green chemistry approach that non-toxic and economic. In this research Ag

nanoparticles were synthesized by using Pseudomonas

aeruginosa OG1 (Gram negative bacterium) under dark conditions. The

synthesized Ag nanoparticles were characterized by transmission electron microscopy

(TEM). Hylopterus pruni collected

from apricot leaves. Fresh leaves were placed in petri dishes with wet cotton

and 10 H. pruni were placed on them

and nanoparticle solution (100 ppm) was sprayed on them. Sterile distilled water was used as a control.

The activity was recorded after 24 h. Our

results suggest the possibility of using AgNPs to eliminate pests and can be

used as valuable tools in pest management programs of H. pruni.<o:p></o:p>
