In order to study the host preference of female mosquitoes, samples were taken fortnightly in Cordoba and Cosquin (Argentina), during October-April of two consecutive years. Four different vertebrates were used in baited-can traps: frogs, chickens, rabbits and turtles. The genus Culex acounted for 92.9% of the specimens collected, Aedes for 7.0% and Psorophora ciliata 0.02%. The highest proportion of females were collected in chicken traps (68.7%), followed by rabbit traps (29.9%), turtles (0.8%) and frogs (0.5%), thus the majority of the mosquitoes were collected in traps with homeotermous hosts. Only Culex dolosus fed on all the hosts. Culex acharistus, Cx. chidesteri and Cx. quinquefasciatus fed on chickens, rabbits and turtles. Aedes albifasciatus, Ae. scapularis, Cx. bidens and Cx. coronator fed on both homeotermous hosts. Culex apicinus, Cx. maxi, Cx. saltanensis and Cx. spinosus fed only on chickens and Ps. ciliata only on rabbits.
