Abstract

Outbreaks of Culex inatomii occurred widely in disaster areas of the tsunami caused by the Great East Japan earthquake in March 2011. Mosquitoes were collected in southern Miyagi Prefecture and northern Fukushima Prefecture in August and September 2011, respectively. In southern Miyagi Prefecture, the average number of adult Cx. inatomii collected by a suction trap baited with 1 kg of dry ice ranged between 69.3 and 132.8 per day in locations within 2.6 km from the coast in tsunami areas, while no Cx. inatomii individuals were collected 8.3 km from the coast, where seawater did not reach, and which therefore escaped the tsunami disaster. There were many ground pools of brackish water of various sizes, and larvae of Cx. inatomii were collected in 48% and 36% of the pools examined in Miyagi Prefecture and Fukushima Prefecture, respectively. Ecological notes on the larval habitats, biting behavior, seasonal prevalence, and reproduction of Cx. inatomii are presented for reference based on ecological studies conducted in Sakata Wetland, Niigata Prefecture, central Japan, in June and August 2011. Ecological factors relating to the current outbreak and the potential medical importance of Cx. inatomii are discussed.
