African Animal Trypanosomosis is the major constraint of livestock production in tsetse infested areas of Ethiopia and is the major challenge in Dawuro zone. Various interventions have been applied to control the disease in tsetse infested areas. However, there is a shortage of information on the impacts of these control methods. A cross-sectional study was conducted from November, 2017 to June, 2018 with the aims of assessing the apparent prevalence of the diseases and density of tsetse flies and the impacts of applied control interventions. The trap deployment and questionnaire survey were conducted. The apparent density of tsetse and Stomoxys were 5.37 FTD and 0.39 FTD respectively. The overall mean vector density of pre-intervention was 0.17 + 0.38 while post intervention was 5.50 ± 0.51 respectively. The findings of the questionnaire survey showed that livestock keepers were familiar with ruminant trypanosomosis, its vectors as well as the effect of the major control interventions applied in areas. There are continuous control interventions applied in the area but the results show that the disease prevalence and apparent density were increasing. Therefore, a comprehensive national wise evaluation of the impacts of control interventions should be undertaken.
