The species hence populates a wide range of environments in contrasted ecological settings often exposed to strong seasonal fluctuations. In the dry savannahs of West Africa, this mosquito population dynamics closely follows the pace of surface water availability: the species pullulates during the rainy season and is able to reproduce throughout the dry season in areas where permanent water bodies are available for breeding. The impact of such environmental fluctuation on mosquito development and the phenotypic quality of emerging adults has however not been addressed in details. Here, we examined and compared phenotypic changes in the duration of pre-imaginal development, body dry mass at emergence and wing size, shape and surface area in young adult females An.coluzzii originated from five distinct geographic locations when they are reared in two contrasting conditions mimicking those experienced by mosquitoes during the rainy season (RS) and at the onset of the dry season (ODS) in Burkina Faso (West Africa). Our results demonstrated strong phenotypic plasticity in all traits, with differences in the magnitude and direction of changes between RS and ODS depending upon the geographic origin, hence the genetic background of the mosquito populations. Highest heterogeneity within population was observed in Bama, where large irrigation schemes allow year-round mosquito breeding. Further studies are needed to explore the adaptive value of such phenotypic plasticity and its relevance for local adaptation in An. coluzzii. %G English %2 https://univ-rennes.hal.science/hal-01102745/document %2 https://univ-rennes.hal.science/hal-01102745/file/Seasonal%20variation%20in%20wing%20size%20and%20shape.pdf %L hal-01102745 %U https://univ-rennes.hal.science/hal-01102745 %~ IRD %~ CIRAD %~ SDE %~ INSU %~ UNIV-RENNES1 %~ UR2-HB %~ CNRS %~ UNIV-LYON1 %~ OSUR %~ GIP-BE %~ ECOBIO %~ AGROPOLIS %~ UR1-UFR-SVE %~ UR1-HAL %~ UR1-SDV %~ ECOBIO-PHENOME %~ AGREENIUM %~ UNIV-RENNES2 %~ B3ESTE %~ UNIV-MONTPELLIER %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ UDL %~ UNIV-LYON %~ INRAE %~ ANR %~ UR1-ENV %~ UM-2015-2021 %~ TEST3-HALCNRS
