A year round ecological study of Glossina morsitans submorsitans variety ugandensis was carried out from September 1980 to August 1981 in the Finchaa river valley in the western part of Ethiopia. Two sampling methods, namely vehicle patrol and screen/handnet capture were employed. The latter was more efficient. The effect of various environmental factors (e.g. altitude, climate, vegetation etc.) that determine the eco-distribution of this species of tsetse were analysed. The most significant finding was that tsetse were distributed far above the previously known altitude limits.
