    Alternative Strategy: Stump removalIn 2012-2013 Coillte will investigate the extent to which stump removal impacts on Hylobius populations. Stump harvesting is currently being trialled in a number of European countries as a means of recovering biomass for fuel energy. It has been suggested that, as the removal of stumps reduces the availability of breeding sites for Hylobius, it may reduce Hylobius feeding damage on restocking sites (Egnell et al., 2007). Even if this is the case, stump harvesting could only ever be used on a small number of sites, given the potential environmental risks associated with harvesting stumps on unsuitable/nutrient poor sites (Moffatt et al., 2011).

    Alternative Strategy: Insect-killing nematodes have been used for decades in horticulture, but their use in forestry is relatively new. In small-scale trials, when nematodes were applied to stumps 12-24 months after felling, the number of adult H. abietis emerging from nematode-treated stumps was significantly reduced (Dillon et al., 2006, 2007). Based on those, and other trials, the recommended rate of application for pine weevil control is 3.5 million nematodes per stump, applied in 0.5 L of water.

    Alternative Strategy: Fallowing Might be an option on upland sites where competing vegetation is not a major issue. As weevils only emerge from stumps for the first 4-5 years after felling, one obvious option would be to delay replanting until the number of emerging weevils falls below economically damaging levels.

    Alternative Strategy: Since 2006 Coillte have been trialing a number of feeding barriers A latex type paint which, when applied to the lower 50 % of the plant, Coating the lower 60% of a plant in fine sand (grain size = 0.2 mm) embedded in an acrylate dispersion. Seedlings are treated in the nursery by a large-scale application procedure involving four steps: (i) spraying the seedlings with water; (ii) application of fixative to the lower sections of the stems, (iii) application of fine sand to the fixative; and (iv) drying of the fixative
