Bioefficacy of Cinnamomum tamala essential oil against Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus larvae

Author(s): Parul, SP Singh and Lalit Mohan
Abstract: Mosquitoes are responsible for causing millions of deaths annually by transmitting dengue, malaria, lymphatic filariasis, chikungunya, etc. Plant-derived insecticides may serve as a suitable alternative for managing these nuisance-creating vectors. The objective of the present study was to find out the bioefficacy of essential oil from Cinnamomum tamala leaves against Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus. The essential oil was extracted from the fresh leaves by the hydrodistillation method and different oil concentrations were applied against the 3rd instar larvae of the mosquito species. The bioassay results showed different responses between the species. The essential oil showed higher efficacy as a larvicidal agent against Culex quinquefasciatus (LC50 = 52.9 and LC90 = 147.5 ppm after 24 hrs and LC50 = 30.5 and LC90 = 81.7 ppm after 48 hrs. of exposure), Aedes aegypti (LC50 = 65.1 and LC90= 239.3 ppm after 24hrs, LC50 = 34.2 and LC90 = 111.6 ppm after 48 hrs. of exposure) and Anopheles stephensi (LC50 = 85.6 and LC90= 235.7 ppm after 24 hrs. and LC50= 53.6 and LC90 = 145.6 ppm 48 hrs. of exposure) respectively. Therefore, it can be inferred that the essential oil derived from Cinnamomum tamala leaves exhibits larvicidal potentiality which could further be used in mosquito larval management.
