  abstract = {{A}nopheles funestus is one of the major vectors of malaria in sub-saharan {A}frica. {B}ecause of several cycles of recurrent drought events that have occurred in the sahelian zone, this species had disappeared from this area since the 1970s following a disappearance of its specific breeding sites. {I}ts comeback was, however, recently observed particularly in the {S}enegal {R}iver basin following the implementation of two dams. {B}ecause the implementation of hydro-agricultural and irrigation settings are suspected to be involved in the reestablishment of {A}n. funestus populations and that paracentric inversions are involved in the adaptation to various environments, the present study was undertaken in 3 villages of the {S}enegal {R}iver basin ({K}eur {M}baye, {M}bilor and {G}ankette {B}alla), (i) to study the chromosomal polymorphism of the newly established {A}n. funestus populations in the {S}enegal {R}iver basin using paracentic inversions from ovarian nurse cells and (ii) their relationship with other populations of this species located in different environmental contexts ({D}ielmo in sudanian zone, {S}ankagne and {K}ouvar in northern sudano-guinean zone and {N}gari in southern sudano-guinean zone) in order to know the key factors leading to their reestablishment in this area. {O}ur results showed that the newly established {A}n. funestus populations' exhibit low level of chromosomal polymorphism with two chromosomal inversions (the fixed 2{R}s and the polymorphic 3{L}a) out of the 9 paracentric inversions described up to now in {A}n. funestus in {S}enegal. {A}t population level, no significant deviation from {H}ardy-{W}einberg equilibrium was observed for almost all inversions. {F}urthermore, significant genetic differentiation was revealed between the populations from the {S}enegal {R}iver basin and those from the sudanian and southern sudano-guinean zones and was not linked to geographical distance. {H}owever, the populations from the {S}enegal {R}iver basin were close or slightly differentiated to those from the northern sudano-guinean zone located within or near irrigated cultures. {T}hese observations suggest that the hydro-agricultural settings following the implementation of dams in the {S}enegal {R}iver were probably responsible to the comeback and the reestablishment of the {A}n. funestus populations in this zone.},
