Abstract
Control of mosquitoes by using chemical insecticides creates several problems including development of resistance. This leads to find out alternative methods via plant products. Viewing this in mind, methanolic extracts of Colocasia esculenta, Eclipta prostrata and Wrightia tinctoria leaves were tested against II, III, IV instars and pupa of filarial vector Culex quinquefasciatus. The LC50 value obtained for IV instar larvae of Cx. quinquefasciatus is 165.697 ppm for C. esculenta while it is 114.257 ppm for E. prostrata and 210.298 ppm for W. tinctoria. Of the three plants studied E. prostrata is most effective in controlling mosquito larvae than the others.
