  The efficacy of synthetic inorganic insecticides to control malaria vector mosquitoes is compromised by increased mosquito resistance to insecticides. Furthermore, use of inorganic insecticides raises serious environmental toxicity concerns. The test plants, Oreosyce africana and Piper capense were identified in Ethiopia through ethnobotanical leads obtained on the basis formal and informal field interviews and discussions coupled with literature search for sister species tested elsewhere. The plant powder from these species was extracted using 80% methanol and the methanol crude extracts of Oreosyce africana and Piper capense were sequentially fractionated with solvents (dichloromethane, ethyl acetate and deionized water). Each fraction was dissolved in dimethyl sulfoxide and deionized water; test .. View More»
