Pedilanthus tithymaloides (Euphorbiaceae) leaf extract phytochemicals: toxicity to the filariasis vector Culex quinquefasciatus (Diptera: Culicidae).


An ethanolic extract of Pedilanthus tithymaloides L. (Euphorbiaceae) leaves was tested for biological activity against the eggs, larvae, and pupae of Culex quinquefasciatus.
