Information about the pest larvae (caterpillars) of oak processionary moth (Thaumetopoea processionea), including its biology, distribution, management and control.
The oak processionary moth is a serious forestry pest that is capable of causing complete defoliation of oak trees. Its caterpillars are also a hazard to health. Breeding populations of the moth were discovered for the first time in the UK in London in 2006 and these initial infestations have since spread and the moth […]
Management of oak processionary moth (OPM) is becoming an increasing challenge to land managers of trees and woodlands in urban and rural areas as the pest continues to spread outwards from original infestation sites in London. This work looks at how landowners and other managers of trees are responding to...
This project is carrying out experimental trials to improve and standardise the use of pheromone traps for monitoring populations of oak processionary moth.
If you own or manage oak trees in the area affected by oak processionary moth (OPM), you need to check which OPM management zone your trees are in. This will help you to decide what action you need to take.
There are currently three geographically-distinct OPM management zones.
Established area
This is the area where OPM is established in the South […]
