Larvicidal, adulticidal, repellency and smoke toxic efficacy of Ficus krishnae against Anopheles stephensi Liston and Culex vishnui group mosquitoes

ObjectiveTo establish the plant Ficus krishnae as potential antimosquito agent.MethodsLarvicidal and adulticidal efficacy of ethyl acetate and methanol extracts of leaves of Ficus krishnae were evaluated against 3rd instar larvae and adults of Anopheles stephensi and Culex vishnui group mosquito for 24 h. Smoke toxicity test along with test for repellency on adult forms of the two mosquitoes were performed by the methanol extract.ResultsThe mortality rate varies in a dose dependent characteristic. The tests for larvicidal and adulticidal activity with both the solvent extracts showed significant efficiencies against the mosquitoes studied. The outcome of smoke toxicity test and repellency test were impressive.ConclusionThe study reveals that the solvent extracts of Ficus krishnae could be an effective natural alternative to get control over the mosquito population.
