The towns of the "Top End" of the Northern Territory are to various degrees adjacent to tropical wetlands, localised swamps, or wet season flooded areas, which can produce seasonally high numbers of a range of pest and potential vector mosquito species. These towns are both receptive and vulnerable to a number of endemic mosquito borne virus diseases including epidemic polyarthritis. Barmah Forest disease, and Australian encephalitis. Due to the proximity of some residential areas of Darwin to extensive wetlands and the large number of residents potentially exposed to mosquito attack, this city has the most comprehensive mosquito control program. The other towns in the Northern Territory have mosquito control programs that are appropriate to their locality, their specific mosquito problems and the practicality of various control methods. This paper outlines an overview of current insecticide mosquito control programs in the Northern Territory, with details of the extensive aerial larval control program and prospects for future control.
