Using some of the most abundant human skin bacterial species, we created in vitro community models to assess whether increased microbial biodiversity could reduce human attractiveness to females of the dengue fever mosquito Aedes aegypti and whether co-culturing bacterial commensals affects overall attraction. More complex bacterial models were less attractive to female mosquitoes than the simplest models. For instance, the triple bacterial community model was approximately three times less attractive than Staphylococcus epidermidis alone. Our data show, for instance, that an in vitro community model mimicking the skin composition of a highly attractive individual to the anthropophilic Anopheles gambiae was also more attractive to anthropophilic Ae. aegypti than a community model mimicking the skin composition of a poorly attractive individual to An. gambiae. In line with these results, volatile analyses of the blends emitted by the different in vitro community models showed that the more complex models had lower emission overall. Effects on mosquito responses differed sharply when the different bacteria species were sharing the same resources used for growth, showing that either competition or commensalism may influence their relative growth, and that this consequently can influence mosquito responses. We conclude that studies on mosquito responses to skin volatiles need to take the microbial community into account. date: 2023-05-23 date_type: published publication: Frontiers in Ecology and Evolution volume: 11 full_text_status: public pagerange: 1-10 official_url: https://doi.org/10.3389/fevo.2023.1156311 id_number: doi:10.3389/fevo.2023.1156311 issn: 2296-701X contact_email: dani.lucas-barbosa@fibl.org conf_subm: not_subm voa3r_agrovoc_lang: en voa3r_agrovoc_lang: en voa3r_agrovoc_value_string: in vitro voa3r_agrovoc_value_string: mosquitoes -> Culicidae voa3r_agrovoc_value_uri: http://aims.fao.org/aos/agrovoc/c_37563 voa3r_agrovoc_value_uri: http://aims.fao.org/aos/agrovoc/c_2016 fp7_project: no access_rights: info:eu-repo/semantics/openAccess citation: Lucas-Barbosa, Dani; Balvers, Carlijn; Bellantuono, Anthony J.; Castillo, John S.; Costa-da-Silva, André L.; De Moraes, Consuelo M.; DeGennaro, Matthew and Verhulst, Niels O.
