A cross-sectional study under taken from January, 2019-Jun, 2019 in Durbe and Demebile ossa kebeles of Bonke district, Gamo Zone, South nation nationalities and people region state (SNNPRS), Ethiopia.The objective of study was to determine the prevalence of trypanosomiasis, associated risk factors for the occurance of the disease, and tsetse density in the area.A simple random sampling method was used to collect blood samples from 384 scattle and analyzed using conventional hematological and parasitological techniques.The overall prevalence of trypanosome infection in the study area was 1.82% (7/384).However, there was no a statistical variation among the two districts (p >0.05).Most of the infections were due to Trypanosoma congolense (1.30%) followed by Trypanosoma vivax (0.52%).This study showed a significant (p 0.05).Again the prevalence among young and adult animals was assessed with a recorded of 0.52% for young and 1.3% for adults animals and there was no statistically significant difference among age groups (p>0.05).The prevalence of disease among parastemic and aparasitaemic animals was recorded as 1.82% and 0%, respectively.In each study area, entomological surveys were conducted using 10 NGU trap with 5 trap in Dembele ossa and Durbe PAs and Glossin pallidipes were the only tsetse fly species caught in the study area along with other biting flies; Stomoxys , tabanus and other different flies.Over all apparent density of the mean tsetses and biting flies of 1.6 and 6.53 were recorded respectively.Due to huge economic loss by this disease strict vector control techniques in complementary with sterile insect technique should be undertaken for eradication and to increase production and productivity for the farmers.
