Giant pine scale

Giant pine scale (Marchalina hellenica) is a scale insect which feeds on pine tree sap.

Samples in Victoria and metropolitan Adelaide confirmed the first recorded detections of the insect in Australia.

Large populations of the insect cause:

  • branch dieback
  • gradual desiccation
  • tree death.
The insect can be found in the cracks and under the bark of the trees, hidden under the white cotton-like wax it secretes, which is the most obvious sign of the pest. Giant pine scale has a low mobility, with most movements being attributed to spread by people.
