The introduction of target-specific adult
mosquito traps (Biogents® (BG) sentinel
mosquito traps) in 2009/10 to detect exotic
dengue vectors at Darwin port facilities has
apparently increased the ability and frequency of their detection. The latest detection of Aedes aegypti at Frances Bay in Darwin in January 2011 was followed by subsequent successful elimination measures and heightened surveillance responses, which indicated no further presence of adults or larvae of this species.
