Larvicidal activity of selected medicinal plants against dengue vector Aedes aegypti

Author(s): K Dass, S Sujitha and P Mariappan
Abstract: The use of synthetic chemical pesticides to control mosquitoes has resulted in a slew of issues, including practical, ecological, insecticide susceptibility, financial, and toxicity to co-inhabitant organisms. Therefore, new ways for eradicating Aedes aegypti using medicinal plant active bio compounds. The purpose of this study was to assess the larvicidal effectiveness of Aegle marmelos and Coleus aromaticus plants methanolic extracts against Ae. aegypti larvae and pupa. The 24 hour LC50 values for II, III, IV instars, and pupa for methanolic solvent leaf extracts of A. marmelos are 124.27ppm, 145.07ppm, 178.87ppm, and 225.99ppm, respectively. The LC50 value for C. aromaticus plant extract was 62.46 ppm in the II instar, 81.94 ppm in the III instar, 101.19 ppm in the IV instar, and 124.34 ppm in the pupa. A. marmelos II, III, IV instars, and pupa have LC90 values of 222.74ppm, 283.43ppm, 354.02ppm, and 439.73ppm, respectively, after 24 hr. C. aromaticus, respectively, 162.87 ppm for the II instar and 202.83ppm for the III instar.213.63 for the IV instar and 254.14ppm in the pupa.
