Glossina

Taxonomic level: Genus

Glossina, the tsetse flies, are vectors of African trypanosomes, which are of medical and veterinary importance. Glossina morsitans distribution is not accurately known in all countries. The subspecies G. morsitans submorsitans extends as a very large but broken belt throughout West Africa, into southern Sudan, northern Uganda.and Ethiopia. Very large belts of G. morsitans centralis occur in Zaire, Zambia, Angola, Botswana, Tanzania, Rwanda and Burundi; belts of G. morsitans morsitans occur in Tanzania, Mozambique, Zimbabwe, Zambia and Malawi. The boundary separating the two subspecies G. morsitans centralis and G. morsitans morsitans corresponds roughly with the Atlantic/Indian Ocean watershed. Glossina morsitans morsitans is one of the major vectors of human African trypanosomiasis in eastern Africa.

Glossina morsitans

Occurs only in the east coast countries of Somalia, Kenya, Tanzania, Mozambique and northeastern parts of South Africa. It has also been recorded from Zimbabwe. Vector of Animal African Trypanosomiasis.

This species is widely scattered throughout eastern parts of Africa, from Ethiopia and Somalia in the north, to Mozambique and South Africa in the south. There is a large belt west of Lake Tanganyika, in Zaire. Ancestral vector of Animal African Trypanosomiasis (AAT).

Occupies a very large inland block of Africa centred on Zaire, but covering some of the land in all of the countries surrounding Zaire, as well as Gabon, Cameroon and the southern part of Chad. Vector of Trypanosoma brucei rhodesiense in East Africa.

Extends along the Kenya and Somalia coastal regions and is abundant in Somalia along certain river valleys. It is also present in Ethiopia, Sudan, Tanzania, Mozambique, Zimbabwe, Zambia, Zaire and Uganda. Major vector of Trypanosoma brucei brucei, minor vector of Trypanosoma brucei rhodesiense.

Lives in the more humid areas of West Africa, from Senegal to Cameroon, then south along the coast to Angola. In West Africa it penetrates further to the north in Mali and Senegal, than it does in Nigeria. In the part of its distribution from Cameroon to Angola, it has a long common boundary with G. fuscipes, with which there is little overlap. Vector of Trypanosoma brucei gambiense in West Africa.
