Ethnobotanical study of plants used for traditional control of mosquitoes and other arthropod pests in the Ghibe valley, southwest Ethiopia

Plant species Eucalyptus globulus, Calpurnia aurea, Phytolacca dodecandra, Echinops kebericho, Croton macrostachyus and Juniperus procera were more frequently cited to be insecticides against human biting arthropods while Melia azedarach L., Olea europaea subsp. cuspidata, Coleus abyssinicus, Croton macrostachyus, Eucalyptus globulus, Lippia abyssinica (Otto & A. Dietr.) Cufod., and Juniperus procera were more frequently reported to be repellents. Some of these plants (Coleus abyssinicus, Croton macrostachyus and Echinops kebericho) have not yet been investigated in depth and thus require scientific evaluation for their efficacy as insecticides and or repellents against malaria-transmitting mosquitoes in Ethiopia.
