Abstract
Plant synthesized nanoparticles gives rapid control of mosquito larvae of dengue vector, Aedes albopictus. Hence, the present study evaluated AgNPs synthesized from the plant, Argemone mexicana for the control of larvae and these nanoparticle were subjected to analyzed by UV-vis Spectrophotometry, Fourier transform infrared spectroscopy, scanning electron microscopy, and transmission electron microscopy. Furthermore, laboratory evaluation of plant mediated nano-particle was carried out lethal toxicity on Aedes albopictus. The characterization studies confirmed that the spherical shape and size (5-50 nm) of silver nano-particles. The efficacy of AgNPs tested concentration at of 2 to 10 ppm against L1 to L4 larval instar of A. albopictus. The LC50 followed by LC90 values are (L1) 5.24, 8.66; (L2) 5.56, 8.85; (L3) 6.20, 10.01 and (L4) 7.04, 10.92 at 10 ppm of silver nanoparticle Whereas, LC50 (LC90) values of (L1) 7.63, 11.58; (L2) 8.17, 11.88; 8.80, 12.82 and 8.94, 12.26 at 10 ppm of plant extract alone treated larvae, respectively. The mortality rates were positively correlated with the concentration of AgNPs. Significant (P<0.05) high square value ch...
