Laboratory study on larvicidal properties of leaf extract of Calotropis procera (Family-Asclepiadaceae) against mosquito larvae

J Commun Dis. 2005 Jun;37(2):109-13.

Abstract

Fresh leaf extract of milkweed (Calotropis procera) showed larvicidal properties against mosquito larvae of Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti. Methanolic extracts of the same plant were, however, more effective as larvicide. C. procera is a weed growing in uncultivated soils as well as in dry, arid zones in Indian subcontinent throughout the year. The results of this study suggest the utility of milkweed as potential technology for control of mosquito larvae.
