Developing a decision support system for managing Hylobius abietis

 

Work undertaken by Roger Moore of our Tree Health Division has shown that there are consistent and predictable patterns of Hylobius abietis (Large Pine Weevil) population development and damage following clearfelling. This work has also shown that there is a strong relationship between populations and transplant damage.

Using information supplied by Technical Services Unit (TSU) from studies at Dornoch and Kielder Forest Districts, Roger has built predictive models that forecast population trajectories and transplant damage on a site-specific basis.

These models will shortly be delivered as a software package called the Hylobius Management Support System (MSS) that will be available by subscription. The Hylobius MSS is based upon an evaluation of site characteristics together with local Hylobius population monitoring which can be offered as a contract service by TSU. 

The information collected can then be used by the forester to determine the best management options for reductions in transplant damage caused by Hylobius. The Hylobius MSS will also look at options to reduce Hylobius populations where this is practical.
