Aircrafts arriving at Narita International Airport, Japan were inspected for mosquito vectors of human diseases accidentally introduced into the country. During 5 years from 2001 to 2005 a total of 2, 161 aircrafts were inspected and 28 adult mosquitoes were found from 26 (1.2%) of the aircrafts. Thirteen aircrafts with mosquitoes came from North and South America, 12 aircrafts from Asia and Oceania, and one aircraft from Europe. The mosquito species found in the aircrafts were Culex pipiens complex, Anopheles sinensis, Aedes vexans nipponii, Cx. tritaeniorhynchus. Mosquito species occurring at the government ordinance area of Narita International Airport were examined by dipping collection of larvae, ovitraps, light traps, and dry ice traps, and identified into 12 taxa belonging to 8 genera. In the terminal building of Narita International Airport, adults Cx. pipiens complex were collected year round suggesting the establishment of foreign vector mosquitoes accidentally introduced from tropical/subtropical areas through aircrafts. All of 15, 231 adult mosquitoes examined were negative for 5 mosquito-borne diseases ; yellow fever, dengue fever, Japanese encephalitis, West Nile fever, and malaria.
