  abstract = {{T}he two main {Z}ika virus ({ZIKV}) vectors, {A}edes albopictus and {A}edes aegypti (invasive and native species, respectively), are present in {G}abon ({C}entral {A}frica). {T}he aim of this study was to determine the entomological {ZIKV} risk associated with these mosquito species in {G}abon by evaluating their vector competence for an {A}frican (i.e. representative of the endemic strains circulating in sub-{S}aharan {A}frica) and two {A}sian (i.e. representatives of exogenous epidemic strains that could be introduced) {ZIKV} strains. {T}he transmission efficiency of one {A}e. aegypti and two {A}e. albopictus field-collected populations from {L}ibreville and {F}ranceville was assayed at day 7, 14 and 21 after experimental oral infection. {T}he two mosquito species could transmit all three {ZIKV} strains already at day 7 post-infection, but transmission efficiency was higher for the {A}frican strain than the non-{A}frican strains (>60% versus <14%; incubation period of 14-21 days). {T}he two mosquito species exhibited comparable vector competence for {ZIKV}, although the amount of viral particles ({A}frican strain) in saliva was significantly higher in {A}e. albopictus than {A}e. aegypti at day 14 post-infection. {T}hese findings suggest that overall, {ZIKV} risk in {G}abon is mainly related to virus strains that circulate endemically across sub-{S}aharan {A}frica, although the transmission of non-{A}frican strains remain possible in case of introduction. {D}ue to its high infestation indexes and ecological/geographical ranges, this risk appears mainly associated with {A}e. albopictus. {V}ector surveillance and control methods against this invasive mosquito must be strengthened in the region to limit the risk of future outbreaks.},
