Hylobius Management Support System training day

4th August 2008

What was the event?

The Hylobius Management Support System (Hylobius MSS) is designed to help foresters predict and reduce damage and costs due to large pine weevil, Hylobius abietis, in upland spruce and pine plantations. The training course will help foresters develop an understanding, in a simple and straightforward way, of how Hylobius populations behave on the site and when they will leave it. Armed with this information and the new management support system, they can then devise site-specific restocking programmes. These can range from no intervention at all - such as simply waiting until after the last Hylobius have departed before replanting the site - to some pesticide use, some nematode use, or a combination of these and other factors, depending on the severity of infestation.

  • Become familiar with the biology and population dynamics of the large pine weevil (Hylobius abietis), and the main measures of population control.
  • Become familiar with population monitoring techniques.
  • Become familiar with the Hylobius MSS software.


The course was partly field-based; including practical demonstrations and fieldwork. The indoor part included a practical exercise using the Hylobius MSS software. The following topics were covered:

  • Biology and population dynamics of the large pine weevil
  • Measures of population control
  • Monitoring: billet specification and site layout
  • Monitoring: data collection
  • Hylobius MSS: data input
  • Hylobius MSS: interpretation of results and analysis of restocking scenarios.

About the Hylobius MSS

The Hylobius MSS is available by annual subscription. A condition of access to the Hylobius MSS is that users/user groups first undergo training in Hylobius monitoring and the use of the web-based system. Subsequently, Hylobius MSS users must register and pay for access to the system and this will also ensure subsequent software and technical support. During registration each user (or user group) will have to inform Forest Research of the number of sites they wish to manage using the system during the following year. Once subscription has been confirmed a username and password will be issued and these are required to log onto the system for entry and retrieval of clearfell site management information from the system servers.
