ABSTRACT
The larvicidal properties of Iris pseudacorus leaves ethanol extract against second-instar larvae of two mosquito species, Culex pipiens and Aedes caspius [Diptera Culicidae] were studied. It was observed that the larvicidal effect of this extract was dose dependent. The LC50 values of I. pseudacorus against C. pipiens and A. caspius were 10.36 and 16.43 mg/l within 24 hr, and 7.36 and 10.1 mg/l within 48 hr, respectively. The miracidiacidal and cercaricidal properties of I. pseudacorus extract were directly tested against Schistosoma mansoni miracidia and cercariae and a time- concentration relationship was observed. The concentrations needed to kill all miracidia [LC100] within 5 min., 30 min. and an hr of exposure were 2.7, 1.6 and 0.9 mg/l, respectively
