Abstract

The toxicity of the aqueous extract and turbid distillate of roots of Petiveria alliacea L. to larvae of Aedes aegypti. Culex pipiens fatigans and Anopheles gambiae were investigated in the laboratory and in the field. Both extracts were larvicidal to second instars. In laboratory tests, a 10% ( v/v) aqueous extract caused 100% mortality in all three species. The turbid distillate was less potent than the aqueous extract under field conditions. The significance of the present findings for mosquito control using locally – an available natural resource is discussed.
Key Words: Petiveria alliacea, larvicidal, Aedes aegypti, Culex pipens fatigans, Anopheles gambiae.
