چکیده انگلیسی
The mosquitocidal activity of aqueous, ethanol, methanol, chloroform and petroleum ether plant extracts of Leucas aspera against Aedes aegypti, Anopheles stephensi and Culex quinquefasciatus was analyzed. The larval mortality of fourth instar larvae of Ae. aegypti, An. stephensi and Cx. quinquefasciatus after 24Â h and 48Â h of treatment was observed separately in control 30, 40, 50, 100, 150, 200, 250, 300, 350, 400, 450 and 500Â ppm concentrations. The plant extracts were screened to identify the phytochemical bioactive compounds. Ae. aegypti was found to be most susceptible than the other species. Based on probit analysis the 24Â h and 48Â h methanol extracts of L. aspera showed pronounced larvicidal activity when compared with the other extracts. An LC50 and LC90 value of methanol extracts against Cx. quinquefasciatus was found to be 37.649Â ppm and 27.855Â ppm (24Â h), 79.150Â ppm and 73.284Â ppm (48Â h) respectively. LC50 and LC90 values were 35.624Â ppm and 20.897Â ppm (24Â h), 64.260Â ppm and 60.096Â ppm (48Â h) against Ae. aegypti. The 24Â h and 48Â h LC50 and LC90 values of ethanol extracts of L. aspera were found to be 40.877Â ppm and 34.359Â ppm, 72.903Â ppm and 67.355Â ppm against An. stephensi. The extracts of this plant showed potent larvicidal efficacy and can be considered for further investigation.
