title: Spectroscopic investigation of biosynthesized nickel nanoparticles and its larvicidal, pesticidal activities.
abstract: Methanolic extract of Cocos nucifera (C. nucifera) was collected using Soxhlet apparatus. C. nucifera methanolic extract was used to prepare Nickel nanoparticles (Ni NPs). Eco-friendly synthesized Ni NPs were confirmed by several analytical techniques such as UV-Visible spectroscopy (UV-Vis), Fourier Transform Infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-ray analysis (EDAX), Transmission Electron Microscope (TEM) and Zeta potential. The obtained results infer that green synthesized Ni NPs are in cubical shape with an average particle size of 47nm. Synthesized Ni NPs were subjected to pesticidal activity against agricultural pest Callasobruchus maculates (C. maculates) which resulted in 97.31% mortality. These results were compared with commercially available standard Azadirachtin. Also we have studied larvicidal activity against Aedes ageypti (A. ageypti) larvae which resulted in LC 50 and LC 90 value of 259.24, 446.99ppm respectively and the result proved to be significant which were processed by ANOVA LSD Tukey's test.
