Mosquito collections using dry-ice traps were conducted at Izumo, Shimane, Japan, from May to October 2008. Trap sites with different surrounding environments (reservoir, riverside vegetation, a shrine in rice fields) and a breeding colony of heron were selected. A total of 4,890 mosquitoes of 16 species in 6 genera were collected by dry-ice traps. Among them Culex tritaeniorhynchus, Cx. pipiens pallens, Aedes albopictus, and Cx. bitaeniorhynchus were the dominant species. The species composition of Cx. tritaeniorhynchus was the highest in riverside vegetation, and Cx. pipiens pallens showed a high species composition at the shrine surrounded by rice fields. The species diversity was compared using the Shannon–Weaner Index. The species diversity was the highest at the breeding colony of heron and lowest in riverside vegetation. A total of 312 females were collected by a sweep net at the breeding colony of heron and 21.5% of them had fed on a blood meal. The proportion of fed females was the highest in Cx. pipiens pallens (80.8%) and next was Uranotaenia novobscura (61.5%) and then Cx. bitaeniorhynchus (30.0%). The breeding colony of heron was found to be an excellent entomological study site to investigate ecological interactions between vector mosquitoes and wild birds.
