IAEA, Vienna, Austria.IAEA 2015. Centers for Disease Control and Prevention. Tsetse can be distinguished from other large flies by two easily observed features. After the suppression activities are completed, no more insecticide is applied in the area. However, since the sexual phase of the trypanosome lifecycle occurs within the tsetse host, biological transmission is a required step in the lifecycle of the tsetse-vectored trypanosomes. Trypanosoma brucei gambiense accounts for the majority of African trypanosomiasis cases, with humans as the main reservoir needed for the transmission, while Trypanosoma brucei rhodesiense is mainly zoonotic, with the occasional human infection.

Inoculation of blood, lymph, or tissue fluid or CSF into laboratory rats or mice is a reliable method to augment For decades, treatment of the two forms of African trypanosomiasis has remained largely unchanged.
The areas occupied by the tsetse fly were largely barred to Tsetse flies are regarded as a major cause of rural poverty in The tsetse fly lives in nearly 10,000,000 square kilometres (4,000,000 sq mi) in sub-Saharan Africa (mostly wet tropical forest) and many parts of this large area is fertile land that is left uncultivated—a so-called In addition to this direct impact, the presence of tsetse and trypanosomiasis discourages the use of more productive exotic and cross-bred cattle, depresses the growth and affects the distribution of livestock populations, reduces the potential opportunities for livestock and crop production (mixed farming) through less draught power to cultivate land and less manure to fertilize (in an environment-friendly way) soils for better crop production, and affects human settlements (people tend to avoid areas with tsetse flies). Since the onset of the meningoencephalitic stage is very insidious, all patients with first stage African trypanosomiasis need immediate CSF examination.

Insecticide-based methods are normally very ineffective in removing the last remnants of tsetse populations, while, on the contrary, sterile males are very effective in finding and mating the last remaining females.

Qualitative support for this claim comes from archaeological findings; e.g., Other authors are more skeptical that the Tsetse fly had such an immense influence on African development. This document is subject to copyright. Trypanosomiasis, tsetse and Africa. Page 170. Unfortunately it is an unattainable ideal, because although the antigen inducing a protective humoral response is well characterized as a surface glycoprotein covering the entire trypanosome, the parasite has the ability to change repeatedly the antigenic nature of this glycoprotein (the variant surface glycoprotein, VSG) and so avoid destruction by the host's immune response through antigenic variation.The molecular basis of trypanosome antigenic variation has received a great deal of attention over the last 30 years so that we now know more about the trypanosome as antigenic challenge than we do about the response of the natural host to infection with the parasite. The house fly is able to spread disease through several routes. If the disease is not treated, it can cause death. is the main vector for trypanosomes, the parasites that cause trypanosomiasis.
