Potential vectors of malaria and dengue at Townsville, Queensland

A biting collection on the banks of Ross River included Anopheles farauti, Adedes imprimens and Ae. alboscutellatus, indicating a relict population of rain-forest mosquitoes and confirming two earlier records of An. farauti from Townsville. Aedes aegypti was collected at Townsville airport. Significance of these findings is discussed in relation to changing urban conditions and a proposed international airport.
