Wax model of Phthorimaea operculella (Gelechidae) larva, magnified x20, made by Judy Bishop, August 1953. Model based on specimen from Victorian Department of Agriculture.
The caterpillar larvae of this pest burrow into the stem, leaves and exposed tubers of the potato plant. The life cycle (egg-larvae- pupa-adult) may be completed in as little as one month, making the potato moth a serious pest.
Carbaryl or Malathion insecticide applied every 7-10 days provides control.
