Resumo: To evaluate the vectorial capacity of mosquitoes for viruses in Japan, the host-feeding habits of the mosquitoes were analyzed by sequencing polymerase chain reaction-amplified fragments of the cytochrome b - 16S ribosomal RNA regions of the mitochondrial DNA of 516 mosquitoes of 15 species from seven genera that were collected from residential areas during 2003-2006. Culex pipiens L. - Aedes albopictus Skuse were the most commonly collected species in urban - suburban residential areas. Anautogenous Culex pipiens pallens Coquillett was distinguished from the autogenous Cx. pipiens form molestus Forskal using a polymerase chain reaction-based identification method. Both Cx. p. pallens - Cx. p. form molestus exhibited similar host-feeding habits, broadly preferring avian (50.0 - 42.5% of avian, respectively) - mammalian (38.6 - 45.0% of avian, respectively) hosts, such as tree sparrows, ducks, - humans. Conversely, Ae. albopictus exhibited a highly mammalophilic - anthropophilic feeding pattern, with 84.2% feeding on mammalian hosts - 68.5% of these on humans. We concluded that in Japan, Cx. pipiens might play a significant role in the avian-to-mammal transmission of viruses, such as West Nile virus, whereas Ae. albopictus might play a role in the human-human transmission of dengue - Chikungunya viruses.
