Project Abstract
The large pine weevil Hylobius abietis is a serious pest of reforestation sites for up to five years post felling, and can kill up to 100% of trees if not protected. Currently, cypermethrin is the only effective insecticide that can be used in Ireland against pine weevil, but its use continues under derogation only until 2021. Thereafter, alternative means of managing pine weevil will be required for Irish forestry to retain Sustainable Forest Management (SFM) certification. Forestry plays an important economic, environmental and social role in Ireland with a contribution to the economy of �2.3 billion; it contributes to rural stabilisation and viability, and climate change mitigation through carbon sequestration. It is national policy to practice SFM, and more generally to reduce chemical pesticide use in accordance with the EU Sustainable Use of Pesticides Directive. Integrated pest management (IPM) seeks to manage pests rationally through appropriate silvicultural practices, biological control, and application of pesticides only when necessary. This proposal will review tools available as components of an IPM system for pine weevil, including alternative pesticides, identifying the strengths and weaknesses of each and its applicability in an Irish context, and identifying knowledge gaps and future research or policy needs. Knowing when plants are at risk facilitates more targeted timing of pesticide application, thereby minimising use. We will use simulation modelling and existing data on weevil populations in Ireland in a novel approach to improve forecasting of weevil attack, and likely impacts of climate change on weevil life cycles. Bringing together Teagasc, Coillte and the higher education sector, with an advisory panel representing regulatory and industry interests, the project will help develop critical mass in IPM in Ireland. Involvement of external assistance from Forest Research will ensure that the project is up to date with research and practice in the UK.
