These to test the larvicidal activity of Aegle marmelos, Coleus aromaticus and Vitex negundo leaf extract are tested against II, III, IV instars and pupa of Culex quinquefasciatus. The LC50 values of V. negundo for II, III, IV instars and pupa is 66.31 ppm, 74.08 ppm, 84.36 ppm and 133.37 ppm respectively. LC50 value obtained for A. marmelos for II, III, IV and pupa is 91.52 ppm, 105.16 ppm, 151.43 ppm and pupa 203.78 ppm respectively. Similarly LC137.77 ppm for II instar, 175 ppm for III instar, 188.36 ppm for IV instar and 221.04 ppm for pupa. Among these three plants studied V. negundo is more effective than other two plant extract. The adult emergence recorded in this study indicates that there a reduction in adult emergence as a function of concentration irrespective of plant extracts studied

This leads to find out alternative methods via plant products. Viewing this mind the present study addresses the green synthesis of silver nano-particles of Aegle marmelos and Colocasia esculenta leaf extract and it is larvicidal activity against II, III, IV instar and pupa of Cx. quinquefasciatus. The synthesized AgNPs were characterized by UV-Vis spectrum, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy analysis (FTIR) and XRD measurements. The II, III, IV instar and pupa of Cx. quinquefasciatus were exposed to different concentration Silver nanoparticles (5 ppm to 50 ppm) for 24 hr. LC50 values obtained for a period of 24 hours for Aegle marmelos leaf nanoparticle was 13.14ppm for II instar, 16.52ppm for III instar, 33.40 ppm for IV instar and 43.21ppm for pupa respectively. Likewise for Colocasia esculenta leaf nanoparticles the LC50 valu...

Likewise for Colocasia esculenta leaf nanoparticles the LC50 value is 9.64ppm for II instar, 13.88ppm for III instar, 32.69 for IV instar and 44.52ppm for pupa. Bio synthesis of silver nanoparticles using leaf aqueous extract of Aegle marmelos, Colocasia esculenta provides potential source for the larvicidal activity against Cx. quinquefasciatus. Among the two plants studied the LC50 values indicate that Aegle marmelos nanoparticles is effective than Colocasia esculenta.
