Aedes (Hulecoeteomyia) japonicus japonicus, also known as the Asian bush mosquito, is endemic to Japan and Korea, although this range has spread to North America and Central-Western Europe. This spread is expected to continue further into North America, Europe, Asia and Hawaii[1]. It is listed as the third most invasive mosquito species reported in Europe[1]. The species is a known vector of West Nile virus, and has been found a competent vector of Chikungunya, Dengue, Japanese Encephalitis and Rift Valley fever in laboratory experiments[2,3].
