In the United States, several\n                    <jats:italic>Culex<\/jats:italic>\n                    species exhibit seasonal shifts in host use, feeding primarily on birds during summer and increasing mammalian feeding in autumn. This shift coincides with seasonal peaks in SLEV and WNV incidence, suggesting that changes in mosquito feeding behaviour may trigger viral spillover to mammals. However, no experimental study has evaluated whether such seasonal patterns occur in South American populations. In this study, it was tested whether an Argentinean population of\n                    <jats:italic>Culex quinquefasciatus<\/jats:italic>\n                    shows seasonal variation in feeding preference under controlled laboratory conditions. Starved females were simultaneously offered a chick (\n                    <jats:italic>Gallus gallus<\/jats:italic>\n                    ) and mouse (\n                    <jats:italic>Mus musculus<\/jats:italic>\n                    ) in dual\u2010choice assays conducted under summer and autumn conditions, both representing a combination of simulated temperature and photoperiod regimes. Blood\u2010meal sources were determined using multiplex polymerase chain reaction (PCR), and feeding proportions were analysed using a Bayesian multinomial logistic regression. Mosquitoes fed on both hosts in both seasons with a high proportion of mixed blood meals, with no consistent evidence of a seasonal host shift. Substantial variation among replicates indicated high intra\u2010population heterogeneity. Overall,\n                    <jats:italic>Cx. quinquefasciatus<\/jats:italic>\n                    exhibited a generalist and plastic feeding strategy rather than a defined seasonal pattern. Although no seasonal shift was detected, the generalist behaviour supports its potential role as a bridge vector of arboviruses in South America.\n                  <\/jats:p>","DOI":"10.1111\/mve.70097","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T11:57:51Z","timestamp":1784289471000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dual\u2010host choice experiments reveal inconsistent seasonal blood\u2010feeding preference in Argentinean\n                    <i>Culex quinquefasciatus<\/i>\n                    populations"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0940-2423","authenticated-orcid":false,"given":"Kevin A.","family":"Rucci","sequence":"first","affiliation":[{"name":"Laboratorio de Arbovirus, Facultad de Ciencias M\u00e9dicas, Instituto de Virolog\u00eda \u201cDr. J.M.
