Three-quarters of Africa south of the Sahara is infested with the Tsetse fly. General speaking, because of the trypanosomes transmitted by these flies. where there are Tsetse flies there are no cattle. Tanzania is a good example. If the maps showing distribution of cattle and Tsetse flies in the Atlas of Tanzania ape consulted. it will be seen that one is the reverse of the other. In Tsetse-infested areas. the flies feed on wild animals which are often present in large numbers, and in these animals the pathogenic African trypanosomes are maintained
