Here, green synthesis of Ag-Co hybrid nanoparticles obtained from aqueous root extract of palmyra palm was reported. The hybrid nanoparticles formation was noticed by a colour change from light pink to light brown and further studied using UV-Vis and FT-IR spectrophotometers. The maximum absorption wavelength, ¦Ëmax as determined by the UV-Visible Spectrophotometer was found to be 420 nm. The FT-IR showed the formation and stabilization of the BMNPs. The nanolarvicidal potency was evaluated by the application of varying concentration ranging from 5 to 50 mg/L against first to fourth instars of larvae and recording the percentage mortality after 24 hours.
