Demirbas-Uzel G, De Vooght L, Parker AG, Vreysen MJB, Mach RL, Van Den Abbeele J, Abd-Alla AMM. 1. We named these constrained fly distributions “control reservoirs” (CRs) and defined them as spatially constrained tsetse fly distributions limited by seasonal fluctuations to suitable habitat. Tsetse flies belong to the genus Glossina in the family Glossinidae. Risk factors for the presence of the fly (vector) Humid temperature of 25o – 26oc Dry sandy beaches under the shade of dense vegetations (breeding sites) The Glossina genus is split into three groups of species based on a combination of distributional, behavioural, molecular and morphological characteristics; these are savannah (Sub-genus Morsitans), riverine (Sub-genus Palpalis) and forest flies (sub-genus Fusca).
