Abstract
The field bio-nanotechnology has provided insight in creation of biosynthetic nanomaterials. Nanoparticles synthesis by entomopathogenic microbes are considered as the novel methods and gained worldwide attention in the field of pest control. This study focused on the synthesis and characterization of CuNPs using Xenorhabdus sp, and their antimicrobial and larvicidal activities with potted plant experiments. 335 nm λmax at UV-Vis spec indicates the presence of CuNPs and functional groups such as alcohols and phenols were confirmed. SEM revealed the clustered shape. EDaX confirms the composition of copper. Crystalline nature were observed in XRD. TEM indicates the particles ranging from 5 to 20nm.The antimicrobial activity against E. coli, P. aeruginosa and Fusarium sp, shows higher zone of inhibition. Larvicidal activity of S. litura shows highest mortality. In potted plant experiment, less damage was observed in CuNPs. Our experiment concludes that, CuNPs synthesized, has highest insecticidal and antimicrobial activity, which can be used in biopesticides.
