Aedes aegypti the vector of dengue fever, has not been collected in the Northern Territory since 1980, and since none have been collected in the Department of Health and Community Services ( DHCS)' s regular and survey trapping programs since then, the Northern Territory (NT) is considered free of this vector.
The DHCS conducts regular mosquito monitoring in Darwin, rural Darwin, Jabiru, Nhulunbuy, Katherine and
Alice Springs, together with fortniqhtly ovitrap collections in Darwin specifically designed to collect container breeding mosquitoes. Airports and ports are also regularly monitored for mosquito introduction by the Quarantine Services.
