Information on the traditional tick control methods used in Keffa, Illubabor and Wellega Provinces in western Ethiopia was obtained from 86 veterinary clinics and 865 peasant farmers through a questionnaire survey. Latexes of Euphorbia obovalifolia and Ficus brachypoda, juice of crushed leaves of Phytolaca dodecandra and Vernonia amygdalina, fruit juice of Solanum incanum, crushed seeds of Lepidium sativum mixed with fresh cattle faeces, juice of crushed leaves and bark of Calpurnea aurea and commercially available spice of Capsicum spp. mixed with butter, were used by peasant farmers to control ticks. Preliminary in vitro efficacy tests of these plant preparations were performed on engorged female Boophilus decoloratus. Preparations of Capsicum spp., E. obovalifolia, S. incanum and F. brachypoda were found to have 30-100 % killing effects. Subsequently, in vivo treatment trials of these preparations were conducted using indigenous Bos indicus cattle naturally infested with ticks. Results indicate that treatments at the rate of once per day for 5 consecutive days with the latexes of E. obovalifolia and F. brachypoda can reduce tick burdens by up to 70 % on cattle.
