Pine Weevil Conference
Teagasc in association with Maynooth University and the Department of Agriculture, Food and the Marine (DAFM) are organising a free, one-day conference on 4 May 2022 focusing on integrated pest management for pine weevil in Ireland.
PW-IPM: Towards integrated pest management for pine weevil in Ireland
Tullamore Court Hotel, Wednesday 4 May 2022, 10.30-15.00
Registration is required for catering purposes as a free light lunch will be provided.
At this conference, experts from Teagasc, Maynooth University, Coillte, DAFM, private forestry and the UK will cover topics including the lifecycle and management options of the large pine weevil, pesticide regulations, reforestation and continuous cover forestry. This conference is held as part of the DAFM-funded PW-IPM Project.
The large pine weevil (Hylobius abietis) can cause very substantial tree plant mortality in reforestation sites. Felling a coniferous crop produces a large increase in breeding material for the pine weevil, whilst plant material suitable for adult feeding is reduced. Young trees used for restocking are liable to be heavily attacked by adult pine weevils feeding on the stem from the root collar upwards. Heavy damage can completely girdle stems and cause plant death.
It is estimated that on average 50% of the seedlings on untreated sites in Ireland and the UK are killed by pine weevil during the first few years. European estimates indicate that the pine weevil is the most important pest of reforestation sites in Europe. This will increase the re-establishment costs substantially through the cost of insecticide application, replacing plants and additional weeding.
The PW-IPM project aimed to review current and potential management options to mitigate damage from the pine weevil in Irish reforestation. These findings will be covered at the conference.
