title: Evaluation of larvicidal nature of fleshy fruit wall of Momordica charantia Linn. (family: cucurbitaceae) in the management of mosquitoes.
abstract: In view of the recently increased interest in developing plant-based insecticides as an alternative to chemical insecticides, this study was undertaken to assess the larvicidal potential of the various fruit wall extracts of Momordica charantia (cucurbitaceae) against two species of mosquito vectors, Anophels stephensi and Culex quinquefasciatus. Among the extracts tested, petroleum ether (LC(50) = 27.60; 17.22 ppm and 41.36; 15.62 ppm) extract was found more effective than carbon tetrachloride (LC(50) = 49.58; 16.15 ppm and 80.61; 27.64 ppm) and methanol (LC(50) = 142.82; 95.98 ppm and 1,057.49; 579.93 ppm) extracts towards anopheline and culicine larvae after 24 and 48 h of exposure respectively. Thus, all fruit wall extracts of M. charantia are toxic to both the larval species. M. charantia may, therefore, act as an effective biolarvicide against mosquitoes in the future.
