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 47 nm. 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 againstAedes ageypti (A. ageypti) larvae which resulted in LC so and LC go value of 25924,446.99 ppm respectively and the result proved to be significant which were processed by ANOVA LSD Tukey's test.
