Control of tsetse flies and trypanosomiasis: Myth or reality?
The African trypanosomiasis are among Africa's most devastating diseases. The human disease, sleeping sickness, and the animal disease, nagana, are caused by trypanosomes, protozoan parasites transmitted by tsetse flies, Glossina spp. Attempts have been made to control tsetse and trypanosomiasis for over 70 years, supported by ever-increasing amounts of foreign aid. Although progress has been made in the control of sleeping sickness, this disease still persists in many countries. Nogono excludes cattle from many of the potentially most productive areas of Africa and is a major constraint on economic development. In this paper, Robert Dransfield, Brian Williams and Robert Brightwell review the control of tsetse and trypanosomiasis in the light of recent progress in our understanding of tsetse population dynamics, with special reference to the experience gained in tsetse control on a Maasai ranch at Ngurumon in the Rift Valley of Kenya, and make suggestions for the management and funding of future control programmes in relation to rural development.
