We investigated Ae. albopictus colonization, adult dispersal and host feeding patterns in the anthropic-natural interface of three forested sites covering three biomes in Brazil in 2016. To evaluate whether an ecological overlap exists between Ae. albopictus and sylvatic yellow fever virus (YFV) in forests, we performed similar investigations in seven additional urban-forest interfaces where YFV circulated in 2017. We found Ae. albopictus in all forested sites. We detected eggs and adults up to 300 and 500m into the forest, respectively, demonstrating that Ae. albopictus forest colonization and dispersal decrease with distance from the forest edge. Analysis of the host identity in blood-engorged females indicated that they fed mainly on humans and domestic mammals, suggesting rare contact with wildlife at the forest edge. Our results show that Ae. albopictus frequency declines as it penetrates into the forest and highlight its potential role as a bridge vector of zoonotic diseases at the specialized BRESIL 052 082 102 7 art. 191 [8 p.] 2018 2222-1751 https://www.documentation.ird.fr/hor/fdi:010074750 10.1038/s41426-018-0194-y 2222-1751 [F B010074750] https://www.documentation.ird.fr/hor/fdi:010074750 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-12/010074750.pdf IRD - Base Horizon / Pleins textes 2019-01-10 2023-07-11 fdi:010074750 fre
