Via the Herald Sun: Harbour mozzie alert. Excerpt:
A rare dengue fever-spreading mosquito - thought to have been eradicated from the Territory in 1969 - has reappeared in Darwin Harbour.
Five different invasions were detected between Toll Marine Logistics at Frances Bay and East Arm Wharf between April and December.
Yellow fever mosquitoes, or Aedes aegypti, were discovered in an insect trap at the Toll Marine Logistics dock on Frances Bay Drive in April, according to a recent bulletin from the Centre for Disease Control (CDC).
And Asian tiger mosquitoes were also found in traps at East Arm Wharf in August, December, and at Toll in August.
Aedes aegypti are normally only found in northern coastal Queensland.
The first batch of mosquitoes were thought to have arrived on the international cargo ship Kathryn Bay on April 22.
Mosquito eggs were also discovered in traps the following month but no other specimens were found. The larvae and pupae were thought to have come from a female mosquito from the cargo ship Starbird, which had previously stopped in Gove and Cairns before arriving in Darwin on May 9.
Traps were set and surveys completed of both boats when the ships were in port.
The port area, including adjoining properties Frances Bay Marine and Paspaley, were sprayed and "fogged" to eradicate mozzies.
Exotic mosquitoes have shown up in the port in the last 12 years, but only once before have as many as five incursions been detected.
