Abstract

Crude leaf extracts of Leucas aspera were tested for their larvicidal activity against Culex quinquefasciatus and Aedes aegypti. The hexane extract of Leucas aspera showed highest larvicidal activity against the two vector mosquitoes followed by chloroform and ethanol. The LC50 values of L. aspera against first, second, third and fouth instar larvae of Cx. quinquefasciatus were 122.50, 149.97, 193.43 and 230.71 ppm and against Ae. aegypti the LC50 values were 77.40, 144.00, 199.72 and 257.17 ppm respectively. No mortality was observed in control. The results were statistically significant at P<0.05 level. The hexane extract of L. aspera showed good larvicidal activity. Â© IJIB, All rights reserved.
