The quantitative and qualitative composition of volatile monoterpenes emitted by uninjured spruce stem bark, and the corresponding internal monoterpene composition of the bark were determined for 15 felled trees in the field. Total emission rates ranged between 0.66 and 60.18 mu-g/dm2 bark surface/h. Total monoterpene content, bark temperature, and field storage time were the most important factors affecting the amount of volatiles released. The most abundant compounds released were alpha-pinene, beta-pinene, and limonene. The composition of emitted volatiles did not at all reflect the internal composition of monoterpenes. Colonisation of the trap trees by different bark beetle species was closely related to the composition of released monoterpene enantiomers
