A new mosquito trial has begun near Cairns as part of a CSIRO project to eradicate Aedes aegypti in North Queensland.
The mosquitos were bred in a lab environment and then the males, which do not bite, were infected with a bacteria that makes their offspring sterile, they were then released en-mass to make any offspring produced with wild females non-viable.
Aedes aegypti transmit many diseases including dengue fever, chikungunya, Zika and yellow fever.
