The fact that botanically-derived chemicals have been recognized as potent tools in mosquito control programme, and that plant-derived insecticides have advantages over the synthetic poisonous chemicals, and are readily biodegradable thus eco-friendly, less harmful to non-target organisms and comparatively cheap, therefore, this study was carried out to evaluate extracts from leaf of F. vallis-choudae (Moraceae: Rosales) for Larvicidal and insect-growth-regulatory activities against Culex quinquefasciatus, as a mosquito model species. There research has shown the great effect of plant extract on egg, larvae of different stages.
