Oak Processionary Moth emergence information and management guidelinesOak Processionary Moth (OPM) larvae have been observed emerging over the last few weeks, signalling the start of the control period. Sightings have occurred as follows:

  • 8th April, Kew Gardens (observed on Turner’s Oak, a hybrid of Quercus ilex and Q. robur);
  • 10th April, Richmond Park;
  • 13th April, Netherlands, near Nijmegen (see attached photo).

 

This appears to be two to three weeks later than 2014, when the first record of emergence I could find was from the Netherlands on 21st March.

The Forestry Commission will begin operations in the Control Zone next week (w/b 20 April).
