Larvicidal efficacy of leaf extracts of Pavonia zeylanica and Acacia ferruginea were tested against the late third instar larvae of Culex quinquefasciatus. The larval mortality was observed after 24 h of treatment. The LC50 values of P. zeylanica and A. ferruginea were 2214.7 and 5362.6 ppm, respectively.
