Mosquitoes in Australia

Mosquitoes are blood sucking insects that are responsible for the transmission of many diseases throughout the human and animal populations of the world

Within Australia there are more than 300 different species of mosquito but only a small number are of major concern

Several important human diseases are transmitted throughout Australia by these insects including Dengue fever, Australian encephalitis, Ross River virus disease and Barmah Forerst virus disease; malaria has been transmitted locally in Australia only rarely in recent decades

In addition to being disease vectors, mosquitoes can cause major disruptions, through their persistent biting, to occupational, recreational and social activities
