Controlling damage by pine weevil

摘要

This article provides an update to the articles written by Tim Liddon and Kerstin Leslie and by Chris Hardy in previous editions of FTN. Preventing damage to young trees by pine weevil on restock sites remains one of the most pressing problems to solve for commercial forestry in Britain, and damage through loss of trees and beat up is estimated in 2012 to have cost €40m per year in the EU (then including the UK). Many possible methods have been identified and research is ongoing but there is currently no simple solution that can be applied to all situations. The problem is made more complex by pressure on the forest sector from government agencies and certification bodies to reduce the use of harmful insecticides, the main method used to reduce damage in Britain.
