Between February 2015 and January 2016 there were 4 separate detections of Aedes aegypti in surveillance traps at Darwin International Airport (DIA). The NT is currently free of establishments of exotic Aedes species however its proven receptiveness for Ae. aegypti establishment has been well documented. The detections at DIA were all associated with aircraft arriving from SE Asian ports with genetic analyses indicating differences between the Ae. aegypti captured at DIA and endemic Ae. aegypti from Queensland (unpublished data).
