His nightmare began when he was in Burkina Faso in west Africa with a team of scientists for a study of the tsetse
flies that transmit sleeping sickness.
How many of us have been eaten alive by tsetse
flies as we were forced to drive slowly through the bush?
Dr Vale pioneered the modern forms of tsetse
control which initially revolved around capturing the flies for sterilisation in situ in the bush, and now focus on attracting tsetse
flies to traps where they may be killed with a relatively environmentally-friendly insecticide.
Transhumance, or the seasonal movement of animals to optimise access to pasture and reduce exposure to vectors such as ticks and tsetse
fies, was central to Maasai husbandry strategies, as it has been to many communities throughout sub-Saharan Africa.
fly spreads the parasitic diseases human African trypanosomiasis, known as sleeping sickness, and Nagana that infect humans and animals respectively.
While the distribution of tsetse
flies in Africa is well known, the researchers did not have maps of tabanids (horseflies, deer flies).
Un programme pluriannuel du Gouvernement du Senegal, avec le concours financier des Etats-Unis et l'appui technique du Centre francais de cooperation internationale en recherche agronomique pour le developpement (CIRAD), est en train d'eradiquer progressivement la mouche tsetse

Others describe the town of Schoemansdal; prospectors; railway lines; transportation, including the role of Alois Hugo Nellmapius and the influence of tsetse

Where do they get this data from and why are they not pursuing the tsetse
fly and mosquito?
In Nigeria, livestock production is limited by trypanosomiasis as tsetse
flies infest about 75% of the nation's land mass3 subjecting the animal population at great risk of the disease.
