Asian Tiger Mosquito Detected on Australian Mainland for First Time

Six Asian tiger mosquitoes (Aedes albopictus) were detected during routine surveillance near the Bamaga community, approximately 750 km north-west of Cairns, on the Cape York Peninsula. This is the first time the species has been found on the Australian mainland.

Key Details

• The mosquitoes were three males and three females.
• The Torres and Cape Hospital and Health Service (TCHHS) stated there is no threat to public health.
• Extensive spraying is underway in the area.
• The detected mosquitoes did not carry any virus.

Background

Aedes albopictus is an aggressive daytime-biting mosquito capable of spreading human viral diseases such as dengue and Japanese encephalitis. The species is known to travel with boats, planes, and trucks and can survive cooler weather better than other tropical mosquitoes.

"This is the first time the species has been found on the Australian mainland."

It was first detected in the Torres Strait in 2004–2005, with prior incursions limited to Australian airports and seaports.

Statements

State MP for Cook David Kempton said the source of the incursion is unknown. He suggested recent illegal foreign fisher incursions as a potential entry point but could not confirm.

University of Sydney Evolutionary Biology lecturer Tom Schmidt said genetic analysis could confirm the origin of the mosquitoes, possibly linking to Indonesian sources via fishermen.

TCHHS acting medical services director Ineke Wever urged residents to take precautions against mosquito bites.

Public Advice

Residents are advised to:

• Wear light-colored, long-sleeved clothing
• Use insect repellent and screens
• Regularly empty water containers to eliminate breeding sites
