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.
