Abstract

<p>Mosquito collection was conducted using dry-ice traps in a rice field area of Tokushima, Japan, from May to October 2009. Six collection sites with different environmental conditions were selected and two CDC-type traps with 1 kg of dry-ice were used to collect mosquitoes at each site. Sweeping collections were also conducted at a breeding colony of herons. A total of 4,347 mosquitoes of 17 species in 7 genera were collected in the dry-ice traps. Culex tritaeniorhynchus, Cx. pipiens group, Cx. bitaeniorhynchus, and Aedes albopictus were the dominant species. The high species composition of Cx. bitaeniorhynchus (14.6%) was observed. A variety of mosquitoes were collected at a reservoir located between the rice field area and the hilly area. A total of 687 females of 9 species were collected using sweeping collections at the breeding colony of heron, and 53.6% of them had fed on a blood meal. The breeding colony of heron was suitable for collecting blood-fed mosquitoes.</p>
