  abstract = {{B}ackground {S}ince its first record in urban areas of {C}entral-{A}frica in the 2000s, the invasive mosquito, {A}edes albopictus, has spread throughout the region, including in remote villages in forested areas, causing outbreaks of {A}edes-borne diseases, such as dengue and chikungunya. {S}uch invasion might enhance {A}e. albopictus interactions with wild animals in forest ecosystems and favor the spillover of zoonotic arboviruses to humans.{T}he aim of this study was to monitor {A}e. albopictus spread in the wildlife reserve of {L}a {L}ope {N}ational {P}ark ({G}abon), and evaluate the magnitude of the rainforest ecosystem colonization. {M}ethodology{F}rom 2014 to 2018, we used ovitraps, larval surveys, {BG}-{S}entinel traps, and human landing catches along an anthropization gradient from {L}a {L}ope village to the natural forest in the {P}ark. {C}onclusions{W}e detected {A}e. albopictus in gallery forest up to 15 km away from {L}a {L}ope village. {H}owever, {A}e. albopictus was significantly more abundant at anthropogenic sites than in less anthropized areas. {T}he number of eggs laid by {A}e. albopictus decreased progressively with the distance from the forest fringe up to 200m inside the forest. {O}ur results suggested that in forest ecosystems, high {A}e. albopictus density is mainly observed at interfaces between anthropized and natural forested environments. {A}dditionally, our data suggested that {A}e. albopictus may act as a bridge vector of zoonotic pathogens between wild and anthropogenic compartments. {A}uthor summary{S}ince its first record in urban areas of {C}entral {A}frica in the 2000s, the anthropophilic and invasive mosquito, {A}edes albopictus, has continued to spread across remote rural areas and has promoted outbreaks of {A}edes-borne diseases, such as dengue, chikungunya and {Z}ika. {S}uch invasion might enhance {A}e. albopictus interactions with wild animals in forests neighboring villages and favor the spillover of zoonotic arboviruses to humans.{I}n this study, we reported the sustained spread of the {A}e. albopictus in the wildlife reserve of {L}a {L}ope {N}ational {P}ark ({LNP}, {G}abon), and we evaluated the magnitude of its colonization of this rainforest ecosystem. {U}sing various sampling methods between 2014 and 2018, we detected {A}e. albopictus presence in wild forest galleries up to 15 km away from {L}a {L}ope, the main inhabited village within the park limits. {W}e demonstrated that {A}e. albopictus can invade forest ecosystems where the human presence is low or absent. {T}hese data indicate that {A}e. albopictus may interact with wild animals and act as a bridge vector of zoonotic pathogens between the wild and anthropogenic compartments. {H}owever, our results showed that {A}e. albopictus population density is higher at interfaces between the village and the forest. {T}his suggests that this species might be present at the interface between anthropized and wild environments where the probability of contact with wild animals is increased, and consequently the likelihood of contributing to sylvatic and bridge transmission of pathogens. {O}ur results also suggested that the presence of humans facilitates the colonization of natural forested habitat by this invasive species.},
