The tsetse fly has plagued Africa for centuries — having sent millions of people into the confusing stupor of sleeping sickness, while killing the cows and other livestock needed to plough their fields and feed their families.17 sep. 2015
- Tsetse flies are regarded as a major cause of rural poverty in sub-Saharan Africa because they prevent mixed farming. The land infested with tsetse flies is often cultivated by people using hoes rather than more efficient draught animals because nagana, the disease transmitted by tsetse, weakens and often kills these animals.
The TseTse fly is unique to Africa and transmits a parasite harmful to humans and lethal to livestock. This paper tests the hypothesis that the TseTse reduced the ability of Africans to generate an agricultural surplus historically.Author:

What is the effect of tsetse fly?
Tsetse flies , through the cyclical transmission of trypanosomiasis to both humans and their animals, greatly influence food production, natural-resource utilization and the pattern of human settlement throughout much of sub-Saharan Africa.
How does African sleeping sickness affect the body?
This immune response? results in symptoms such as fever, headaches, joint pains and itching. Second stage or neurological? phase: this stage begins when the trypanosome parasites cross from the blood-brain barrier into the spinal fluid, infecting the central nervous system including the brain.
How are tsetse flies economically harmful?
Abstract. The TseTse fly is unique to Africa and transmits a parasite harmful to humans and lethal to livestock. This paper tests the hypothesis that the TseTse reduced the ability of Africans to generate an agricultural surplus historically.
Where are tsetse flies found?
Tsetse flies are found in sub-Saharan Africa . Travelers spending a lot of time outdoors or visiting game parks in these areas can be bitten by tsetse flies and get infected.
How do you kill tsetse flies?
The tsetse flies then eventually disappeared because of food shortage. These methods have largely been abandoned and today insecticide spraying is used along with traps and insecticide-impregnated targets. Traps and screens are an effective means of tsetse control.
What disease do Tsetse flies cause?
There are two types of African trypanosomiasis (also called sleeping sickness ); each is named for the region of Africa in which they were found historically. East African trypanosomiasis is caused by the parasite Trypanosoma brucei rhodesiense, which is carried by the tsetse fly.
Is there a vaccine for sleeping sickness?
There is no vaccine or drug for prophylaxis against African trypanosomiasis . Preventive measures are aimed at minimizing contact with tsetse flies.

The adult fly emerges from the pupa in the ground after about 30 days. Over a period of 12-14 days it matures, mates and, if it is a female, deposits its first larva. Thus 50 days elapse between the emergence of one female fly and the subsequent emergence of the first of its progeny.
Can a tsetse fly kill you?
