We studied the difference in emission rates from healthy spruce bark and infested spruce bark, the influence of time since spruce bark beetle infestation started and the difference in emission rates from bark beetle drilled entry holes and exit holes. Bark chamber measurements on bot...

We also found an initial enhancing effect between spruce beetle infes- tation and climate change; however, by the end of 100 yr of climate change and potential beetle infestation, climate had a dampening effect on spruce beetle infestation, through loss of host trees. These results are an ...
Furthermore, salvage and sanitation logging may not be permissible in protected areas (Hlásny et al. 2021). Within integrated bark beetle management (Sweeney et al. 2023), it would therefore be desirable to possess an environmentally friendly tool to reduce the risk of infestation of windthrown...
(Evensen et al.2000; Hammerbacher et al.2011). Despite high stilbene levels, spruce trees suffer from fungal colonisation and fatal bark beetle infestation (Brignolas et al.1995; Schiebe et al.2012). This is attributed to the “fungus effect” (Brignolas et al.1998) resulting in decreased...
Spruce bark beetle infestation Early detection Sentinel-1 Sentinel-2 Vegetation indices 1. Introduction During the last 50 years, the European spruce bark beetle (Ips typographus [L.]) has killed more than 150 million m3 forest in Europe (Schroeder and Cocoş, 2018), where it is the most ...
and nearby trees. An aspect of this embodiment provides for concentrating spruce beetle infestations in selected areas of a forest. Using this method, it is also possible to move the locus of spruce beetle infestation within a forest from one location to another. This involves exposing the ...

Such stages of infestation are common among wood-boring pests (WBPs) such as the European spruce bark beetle (Ips typographus), mountain pine beetle (Dendroctonus ponderosae), Engelmann spruce beetle (Dendroctonus rufipennis), and pine wilt nematode (Bursaphelenchus xylophilus) spread by longhorn ...
