What was the event?
The Hylobius Management Support System 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 helped 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.
At the end of the course trainees were familiar with:
- The biology and population dynamics of the large pine weevil (Hylobius abietis), and the main measures of population control.
- Population monitoring techniques.
- The Hylobius Management Support System (HMSS) software.
The course was partly field-based; including practical demonstrations and fieldwork. The indoor part included a practical exercise using the HMSS 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
- HMSS: data input
- HMSS: interpretation of results and analysis of restocking scenarios
Who was the event suitable for?
Field staff and managers involved in weevil control on restocking sites.
