Giant pine scale

Giant pine scale (Marchalina hellenica) is a scale insect that sucks the sap of pine trees. If established, the insect poses a threat to Australia’s softwood plantation industry by causing:

  • branch dieback
  • gradual desiccation
  • tree death.

Giant pine scale has been detected in Victoria and metropolitan Adelaide. Giant pine scale has:

  • not been found in other parts of Australia.
  • not been detected in any pine plantations.

In South Australia, the Department of Primary Industries and Regions (PIRSA), destroyed all trees known to be infested with giant pine scale - this was completed in late 2016. In Victoria, it has not been possible to destroy giant pine scale.
