In the Niayes region of Senegal, a coastal area close to Dakar, livestock keeping was difficult due to the presence of a population of "Glossina palpalis gambiensis". Feasibility studies indicated that the fly population was confined to very fragmented habitats and a population genetics study indicated that the population was genetically isolated from the main tsetse belt in the south eastern part of Senegal. After completion of the feasibility studies (2006–2010), an area-wide integrated eradication campaign that included an SIT component was started in 2011, and by 2015, the Niayes region had become almost tsetse fly free.
