Spruce bark beetles (<italic>Ips typographus</italic>) cause up to 700 times higher bark BVOC emission rates compared to healthy Norway spruce (<italic>Picea abies</italic>)

Abstract ± µ g m- 2 - 1 ± ± ± µ g m- 2 - 1 during the early and late season respectively. BVOC emission rates were highest at the start of the infestation and decreased exponentially with time, showing induced emission rates for up to 1 year after which the emission rates were similar to those from healthy bark. Constitutive needle emission rates from healthy trees were found to be 11 times higher than bark emissions from healthy trees. However, when Norway spruce trees were infested, the bark emission rates were instead 6 to 20 times higher than the needle emissions, causing substantial increases in the total tree BVOC emission rate. This could lead to high impacts on atmospheric processes, specifically the formation of secondary organic aerosols, which have a higher yield from some monoterpene compounds, which increased from infested trees.
