A Simultaneous Census of the Potential and Actual Food Sources of the Tsetse Fly Glossina swynnertoni Austen

Abstract
At Tarangire in the Northern Province of Tanganyika, warthog, rhinoceros and buffalo comprise respectively, in terms of numbers of individuals, 3, 0.2 and 0.02% of the large mammal population (dik-dik size and above). These same 3 mammal species provided respectively 77.2 and 14% of the food of G. swynnertoni. Impala, 70% of the mammal population, provided less than 1 % of the G. swynnertoni feeds. It is calculated that each warthog loses on the average 13-27 g of blood per day to the tsetse.
