Abstract

Globally, mosquitoes are transmitting agents for diseases like dengue, malaria, filaria and Japanese encephalitis. In this study, the larvicidal activities of silver nanoparticles (AgNPs) synthesized from seaweed Caulerpa taxifolia extract against the larvae of Culex quinquefasciatus was investigated in vitro. The synthesized AgNPs was further characterized using UV-Vis spectroscopy, FTIR, SEM, XRD, DLS and Zeta potential analysis. From the result, the LC50 value for AgNPs identified was 448.66. The synthesized silver nanoparticles have maximum absorption at 430 nm. The FTIR indicated a specific peak in 3275.11cm-1, 2921.7cm-1 and 1244.28cm-1 range. Scanning electron microscopy resulted in spherical shaped approximately ranging from 1 µm to20 µm in size. The average size distributions of Ag nanoparticles were 72.99 nm and are fairly stable with a zeta potential value of -31.1 mV. The biosynthesis of silver nanoparticles with Caulerpa taxifolia extract provides potential source for the larvicidal activity against mosquito. The present study revealed that green synthesized silver nanoparticles can be used as an eco-friendly means for effective control of vector diseases
