Larvicidal potential of Eucalyptus globulus oil against Anopheles stephensi
Author(s): Amaninder Kaur Riat and Devinder Kaur Kocher
Abstract: Malaria transmitted by Anopheles stephensi mosquito is one of the serious infectious diseases among vector borne diseases. Many plant-based extracts/oils have unique larvicidal activity against mosquitoes. This study was designed to determine the toxicity of Eucalyptus globulus oil against An. stephensi larvae. Different concentrations of E. globulus oil @ 50, 60, 70, 80, 90 and 100 ppm were tested against 4th instar larvae of An. stephensi. Mortality was recorded after 3, 6, 12, 24 and 48 hrs. LC50 and LC90 values of toxicity were determined by log- probit technique. Out of these tested concentrations, 90 ppm of E. globulus were calculated out to be the effective ones. LC50 and LC90 values were found to be 46.11 and 69.33 ppm for E. globulus oil, against An. stephensi larvae after 48hours. E. globulus proved to have good potential as a bio-larvicide against An. stephensi and could be used as effective and ecofriendly mosquito control agent in future.
