Larvicidal activity of Sauromatum venosum tuber extract against Culex spp.

Mosquitoes act as the vectors of a variety of diseases that have serious health consequences for humans. In order to stop the spread of disease through mosquitoes, plant extracts have been used as a secure and environmentally friendly alternative to chemical pesticides. Plants produce secondary metabolites that inhibit the growth of insects and exhibit larvicidal activities. In the current study, the Bioefficacy of ethanolic extract of Sauromatum venosum was tested against the fourth instar larva of Culex spp. The LC₅₀ value of ethanolic extract of Sauromatum venosum was 55.571 ppm. The mortality of larvae was examined after 96hours of exposure. The results revealed the promising potential larvicidal properties of the ethanolic extracts of Sauromatum venosum plant against the fourth instar larvae of Culex spp. It has been concluded from this research that larvicidal activities of ethanolic extracts of Sauromatum venosum are due to the presence of phytochemical constituents in it which were confirmed by FTIR spectrum.
