    (Addis Ababa Universty, 2006-06) Amede, Yeshitila; Kumar, Asoke phD.
    Tsetse transmitted animal trypanosomosis is a serious constraint in animal production and Agricuhural development in Ethiopia. The vast area adjacent to the Ghibe valley in South West Ethiopia is tsetse infested where animal trypanosomosis is a serious threat to livestock economic development. The objectives of the study were to investigate the prevalence and magnitude of bovine trypanosomosis in representative and selected villages of Sokoru woreda. to asses and analyze the efficacy trypanocidals in use. to determine the extent of the disease based on the study findings to point out and search for the possible. Sustainable and effective control options of tsetse transmitted trypanosomosis. The study was conducted from September 2005 to Februar 2006. The stud methodology was based on questionnaire survey , seasonal cross sectional studies and longitudinal study for trypanocidals drug efficacy in villages of Abelty and Tiroshashama. The result of the questionnaire suney revealed that all the interviewees agreed that trypanosomosis was the most important and major problematic disease in their area. Cross sectional study was done on 515 sampled - cattle. Animals were examined using parasitological method a buffy coat technique (BCT). A total of 64 monoconical traps were deployed along suspected tsetse habitat in the range of 1.392- 1,629 meters above sea level. And entomological survey revealed that Glossina m. submorsitans was the highly prevalent tsetse fly species followed by Glossina pallidipes and with several Stomoxys spp. The apparent density tsetse was relatively higher in late rainy season (0.194 flies /trap /day) at Abelt in late rainy season and none in dry season respectively where as in Tiroshashama village the fly catch was 0.028 fly/trap/ day in laterainy and 0.017 fly /trap/ day of G.m. submorsitans and 0.017 G.pallidipes was caught in dry season. The fl y catch was declined may be because of the high temperature of the dry season low humidity and bush fire which occurred few weeks before the study period and such condition may damage the suirrable tsetse habitat and also inavailability of favorable hosts in the area. forced the flies to evacuate to the extreme low land areas towards the river basins. Nevertheless high catches of Stomoxys 10 flies /trap / day in late rainy season at Abelty and none flies of Stomoxys/trap/day in dryseason at Abelty. Thirteen flies of stomoxy /trap/ day in dry season 20 flies of Stomoxys /trap/day in dry season atTiroshashama village were caught. In the parasitological sunvey a total of 515 animals out of which 180 cattle in late rainy season 335 cattle in dry season were examined with buffy coat technique and the result showed the prevalence of trypanosomosis was highest in dry season rainy season was observed. A significa nt difference ( P < 0.05) was noticed between the mean PCVvalues in parasitacmic (95 % C I 21.24,23.59) aparasitaemic (95% Cl 23 .93,24.73) cattle.
