Planning Development to Reduce Mosquito Hazard
MetadataShow full item record
Coastal areas within South Eastern Australia continue to experience significant population growth supporting the development of greenfield sites. Yet many nearby coastal wetlands can harbour mosquito hazards, reducing the desirability and full potential of developments. Urban designs that incorporate buffers between development and coastal wetlands can reduce the impact of common nuisance mosquitoes such as Verrallina funerea. However, provision of buffers does not address the hazard from the Saltwater Mosquito, Aedes vigilax a major vector of Ross River and Barmah Forrest Viruses, as this species can travel up to 50 km to find a blood meal, when wind assisted. Control is most effective when targeted at the larval stage and in some areas chemical larvicides are routinely and repeatedly applied, at significant cost. The efficacy of larvicides can be significantly reduced in a range of situations including adverse weather, in wetlands with low pH conditions or dense canopy cover. Alternative habitat based control measures, such as; establishing runnels within saltmarsh, and rehabilitation of mangrove wetlands to restore tidal flushing, can reduce mosquito production in source areas while retaining or improving the delivery of ecosystem services. Here we highlight approaches to bring habitat based mosquito control measures into the planning and ongoing management of periurban areas.
