Abstract
Nanotechnology
is a growing field of materials science, with applications in numerous fields,
including textiles, food storage, refrigerator surfaces, drug delivery, agriculture,
military, electronics, and food production etc., Various types of nanoparticles
may be synthesised using biological entities such as bacteria, fungi and plant
biomass, making them an alternative to chemical nanoparticles. In this regard, the current study focused the
larvicidal efficacy of silver nanoparticles synthesized using Coleus
aromaticus and Wrightia tinctoria against Anopheles stephensi
larvae. The green synthesised silver nanoparticles were characterized by UV-Vis
spectroscopy, FTIR, XRD, and SEM. The 24-hour LC50 and LC90
values of C. aromatics, are10.11 ppm, 15.12 ppm, and 27.65 ppm,
respectively. Whereas the LC90 values are 27.19 ppm, 46.48 ppm, and
58.70 ppm. Similarly, the LC50 values for W. tinctoria are
18.12 ppm, 21.20 and ppm, 33.26 ppm, for II, III, and IV larvae, respectively,
and the LC90 values are 35.66 ppm, 45.32 ppm, and 64.78ppm,
respectively. The results find that the green synthesized silver nanoparticles
from C. aromaticus are effective than W. tinctoria nanoparticles
tested.
