A cross-sectional study was conducted from December 2014 to April 2015 in Duguna Fango district in Wolaita zone. The objectives of the study were to determine the prevalence of bovine trypanosomosis and to assess the distribution and apparent densities of vectors of the trypanosomosis. A parasitological study using buffy coat technique was employed for the determination of prevalence of trypanosomosis while monoconical traps were used for the vector studies. A total of 192 cattle randomly selected from the study population were examined for the parasitological study. The result of parasitological study revealed that the overall prevalence of trypanosomosis was found to be 7.3% in Duguna Fango district.The prevalence showed no significant difference in susceptibility between sex categories and in age groups (P>0.05). From the infected animals the prevalence for trypanosome species was 14.3% and 85.7% for T. vivax and T. congolense, respectively. The mean PCV values of parasitaemic and aparasitaemic animals were 19.7% and 25.7, respectively. About 20monoconical traps in two kebele (Bilate and Anka) of Duguna Fango districts were deployed for 72 hours with odour attractants for the vector studies. There were 22 G. pallidipes and 43 tabanus had been collected from the study site with the respective density of 1.1 and 2.15 fiy/trap/day. Therefore, implementing control of trypanosomosis with an integrated approach was paramount importance in areas of the study site.
