摘      要：Objective:To evaluate the mosquito larvicidal activity of plant ***:The hexane,chloroform,ethyl acetate,acetone,and methanol leaf,flower and seed extracts of Abrus precatorius（***）,Croton bonplandianum（***）,Cynodon dactylon （***）,Musa paradisiaca（***） and Syzygium aromaticum（***） were tested against fourth instar larvae of Anopheles vagus（***）,Armigeres subalbatus （***） and Culex vishnui（***）.Results:The highest larval mortality was found in seed ethyl acetate extracts of *** and leaf extracts of ***, flower chloroform and methanol extracts of ***,and flower bud hexane extract of S. aromaticum against *** with LC50 values of 19.31,39.96,35.18,79.90 and 85.90μg/mL;leaf ethyl acetate and methanol extracts of ***,flower methanol extract of ***, flower bud methanol extract of *** against *** with LC50 values of 21.67, 32.62,48.90 and 78.28μg/mL,and seed methanol of ***,flower methanol extract of ***,flower bud hexane extract of *** against *** with LC50 values of 136.84,103.36 and 149.56μg/mL,***:These results suggest that the effective plant crude extracts have the potential to be used as an ideal ecofriendly approach for the control of disease *** study provides the first report on the larvicidal activity of crude solvent extracts of different mosquitoes.
