| dc.description.abstract | A year-round ecological study of G. lrorsitans ugandi.>nsis \<las carried out fran SeptEmber 1980 to August, 1981 in the Finchaa River Valley in the \'lestem part of Ethiopia. Three different sarrpling rrethods, naJ1\31y Vehicle Patrol rrethod, SCre<'.n/ Hand net rrethod and Biconical Traps ~.BrG c1lt'loyed. All were found to be effective. The mcno-species ccrnposition, the unimodal seasonal fluctuatien and the biphasic diel activity of th3 tsetse flies of the area I,~e determined. The effect of various factors (eg. cl:lIrate, altitude, vcgetatien, etc.) that interplay with the eeo-distribution of this srecies of tsetse fly were statistically tested. Conditiens related to teJ\lpGratures, rainfall vcgetatien and bush-fire affected the fly populatien and distributien. The apparent dansity (A.D.) was high during and after the rainy seasons and lo;q during the dry seascn. '.£'he sex ratio indicated that more males wore captured with the Vehicle Patrol and Screen/Hand net rrethods willIe the reverse was the case with the Bioonical Traps. The age structure of the flies sho;*-Xl that roost of the flies loK?re in the pre-reproductive and reproductive stages. Obscrvatioos en the physiological conditien of the flies depicted a very high proportion of hungry flies and a relative]s l<X-l fed and pregrent flies. Blood-rreal analysis carried out on G.!!!. ugandensis in Finchaa sh<x-.Ed roan, I·dld pig and war.thog to be tho l1lclin vertr)brate hosts. The infectien rate of flies in the valley was l<X-l, although a fairly high infectien rate in cattle was observed en the edge of the eScaJ:j'"llP.nt | en_US |
