Introduction and establishment of Aedes (Finlaya) Japonicus japonicus (Theobald) on the island of Hawaii: implications for arbovirus transmission.

On November 24, 2003, 1 female adult specimen of Aedes (Finlaya) japonicus japonicus (Theobald) was collected in a New Jersey (NJ) light trap on the island of Hawaii. From June through October, 2004, female and male adults were collected by NJ light traps and gravid traps placed at multiple sites on the island of Hawaii. Larvae were collected in artificial containers and reared to adults for identification. Aedes (Fin.) j. japonicus is the 8th mosquito species to be introduced and established in the State of Hawaii. Currently, this species is known only from the island of Hawaii. Aedes (Fin.) j. japonicus is a competent laboratory vector for a number of arboviruses. Increased quarantine inspections, inspection and treatment of imported used tires and plants, disinsection of airline cargo holds, enhanced vector surveillance, and the development of sanitary corridors around airports and port facilities are necessary to reduce the introduction of vectors and pathogens.
