ABSTRACT
Background: Biofabrication of silver nanoparticles from plant origin provides more resistance against mosquitoes. In the present study, silver nanoparticles (AgNPs) synthesized from the novel plant, Menyanthes trifoliata for the control of chikungunya vector, Aedes aegypti. Objective: The nanoparticles were evaluated for their toxicity of larvae, pupae and insect growth regulatory activity, persistent study against Aedes aegypti. Methods: Nanoparticles were analyzed with UV-vis spectrophotometry, SEM, XRD, FTIR, and EDAX. The characterization studies confirmed that AgNPs are of size 10-50nm and spherical in shape. The efficacy of plant-synthesized AgNPs was tested against different concentrations ranging from 5-25 µg/mL against L1 to L4 larval instars and pupae of A. aegypti. Results: Observed value of LC50 = 8.17, 9.78, 12.96, 16.73 and 20.11 µg/mL; the LC90 = 19.57, 24.25, 29.64, 36.95 and 41.81 µg/mL for treated all larval instars and pupae, respectively. The mortality rates were positively correlated with the concentration of AgNPs. Significant (P<0.05) changes in larval mortality were also recorded between the period of exposure to all larval instars of A. aegypti. The larval and pupal growth was significantly diminished (IGR activity) by the action of AgNPs and its emergence inhibition EI50 and EI90 values are 1.87 (10.58) significantly noted against A. aegypti. Conclusion: The study reported that the toxic nature of AgNPs had a significantly higher impact on the third instars, followed by other stages, and their effect lasted up to a 12-week period. Larval midgut layer strongly disrupted and it’s showed in the histology section. These findings reported M. trifoliata synthesized AgNPs are rapid, eco-friendly, and novel mosquito control agents.
