The terrorist attack in Bali on 12th Oct. 2002 lead to the evacuation of Australian citizens via RAAF Hercules aircraft into Darwin between 13th and 16th Oct. 2002. Routine disinsection quarantine procedures such as knock down spraying of arriving aircraft against exotic mosquitoes could not be practised because of the burn wounds of the victims transported. Due to the risk of importation of adult exotic mosquitoes, the Medical Entomology Branch (MEB) and the Australian Quarantine and Inspection Services (AQIS) implemented increased surveillance measures using adult traps and ovitraps from 15th to 23rd Oct 2002.
