ABSTRACT
Acute toxicity tests were conducted to determine the biological effects of partially purified extract of two tropical plants Croton hirtus L'Her., Pogostemon quadrifolius (Benth.) F.Muell on the juveniles of Culex quinquefasciatus Say. Rearing of C. quinquefasciatus larvae in water at concentration less than the critical concentrations for inhibition of adult emergence in 50% of treated larvae (EC50) of the ethyl acetate fraction of Croton hirtus and Pogostemon quadrifolius leaf extracts from hatching to emergence significantly decreased the fecundity of the C. quinquefasciatus and the hatchability of their eggs. At highest concentration of 50% EC50 of the extracts the decrease in the fecundity over the control ranged between 72.4 and 85.4 %.
