The nanotechnology is the most promising branch of nanoscience and a critical component in the creation of new technologies in the twenty-first century. Dengue virus is transmitted primarily by Aedes aegypti though several other Aedes species including Aedes albopictus and Aedes vittatus play a significant part in the virus transmission Dengue fever infections are one of the greatest important arboviral ailments in humans. Identified the phytochemical compounds of Azolla pinnata extracted from different solvents and their possible role in larvicidal activity also to estimate the efficacy of synthesized silver nanoparticles mediated by Azolla pinnata in contradiction of the Dengue vector, Aedes aegypti. Present study exhibited the biocontrol efficacies of Azolla pinnata against Aedes aegypti larvae. The larvicidal activities of the extracts of Azolla pinnata were examined and the results exhibited that the aqueous extract of Azolla pinnata had significant larvicidal activity against the dengue vector, Aedes aegypti. XRD proved to determine the measurement of biosynthesized silver nanoparticles with h, k, l values. As a result, the current study provides a distinctive foundation for Azolla pinnata as prospective larvicidal agents. However, its use might change the shape and behavior of Aedes aegypti larvae.
