Investigation of mosquito breeding at Kansai International Airport, with special reference to Culex inatomii Kamimura and Wada

Abstract

As one of the measures to prevent diseases which might be caused by imported mosquitoes, we conducted a survey on mosquitoes and their breeding sources from April to December, 1998,at Kansai International Airport constructed in 1994 on an artificial island in Osaka Bay, about 5km off the coast of Izumi-Sano City. Nine indigenous species belonging to 3 genera were found, but there were no imported species. The species collected were as follows; Anopheles (Anopheles) sinensis, Culex (Culex) pipiens pallens, Cx. (Cux.) tritaeniorhynchus, Cx. (Cux.) orientalis, Cx. (Barraudius) inatomii, Cx. (Lutzia) halifaxii, Cx. (Culiciomyia) sasai, Aedes (Finlaya) togoi and Ae. (Stegomyia) albopictus. Anopheles sinensis and Cx. inatomii, which was newly recorded outside of the type locality, Okayama, were mainly collected in one water pool made of concrete and temporary ground pools, respectively. Culex p. pallens was very common in water pools made of concrete.
