Abstract
Four Norway spruce, Picea abies, plantations were studied according to the progression of white pine weevil. Pissodes strobi, infestation. Dendrometric characteristics were measured to determine some preferences by the weevil for particular hosts. Furthermore, in two other plantations the weevil's activity was recorded by weekly sampling of attacked leaders until adult emergence.
