Damage caused by insects

Dry and warm weather favors certain insects that can kill large volumes of forest. New insects that come to Sweden can have devastating consequences. What are we doing to save the forest? Here, you find new research from SLU on this topic.

The attraction of the clear cut is so strong that a single hectare may give rise to 100 000 new pine weevils within two years. Hormonal treatment at the nurseries can be an effective tool against this weevil.
