Ipomoea batatas (Convolvulaceae)-mediated synthesis of silver nanoparticles for controlling mosquito vectors of Aedes albopictus, Anopheles stephensi, and Culex quinquefasciatus (Diptera:Culicidae)

Abstract

We proposed an effective and eco-friendly control of dengue, malaria, and filariasis-causing vectors. We tested Ipomoea batatas leaves-mediated silver nanoparticles (AgNPs) against first to fourth instar larvae and adults of Aedes albopictus, Anopheles stephensi, and Culex quinquefasciatus at different concentrations. The synthesized AgNPs showed broad spectrum of larvicidal and adulticidal effects after 48 h of exposure. The characterization of synthesized AgNPs was done using various spectral and microscopy analyses. The maximum efficacy was observed in synthesized AgNPs against the adult of Ae. albopictus with the LC and LC values were 10.069 and 15.657 μg/mL, respectively, followed by others.

Larvicidal and pupicidal evaluation of silver nanoparticles synthesized using Aquilaria sinensis and Pogostemon cablin essential oils against dengue and zika viruses vector Aedes albopictus mosquito and its histopathological analysis

“…Mortality was proportional to the tested concentrations and this was in agreement with a number of previously reported plant-borne extracts [35,36]. Earlier Hye-Mi Park, and his colleagues studied the larvicidal activity of PcEO and showed significant effect against Culex pipiens pallens [37].…”

Green synthesized silver nanoparticles using Andrographis macrobotrys Nees leaf extract and its potential to antibacterial, antioxidant, anti-inflammatory and lung cancer cells cytotoxicity effects

“…Fourier transform infrared (FTIR) spectroscopy helps us find functional groups like phenolic, amines, carboxyl, and alkyl groups, which are responsibility for the reduction of AgNPs in the green synthesis of AgNPs [70]. The current results of the AgNPs FTIR spectrum produced by A. macrobotrys demonstrate peaks for carboxyl, hydroxyl, primary and secondary amine groups, confirming that the liquid served as a capping and stabilising agent in the generation of AgNPs in plant leaf extract.…”

The factors affecting optimisation of phytosynthesis of silver nanoparticles using Indian medicinal plant species and their biological applications: A review

“…The mortality rate at 25 µg/mL concentration was 34.3% and it increased to 81% when the concentration was increased to 125 µg/mL, which reveals that the mortality rate is proportional to the conc. of AgNPs used (33).…”
