White-Pine Weevil Attack on Scotch Pine
Scotch pine is one of the hosts of the white pine weevil (Pissodes strobi Peck), but the injury generally is slight. Northern strains of this tree appear to have the ability to withstand attacks in a great degree. The probable reasons, advanced by the authors, for this are the vigor of the tree and the consequent heavy flow of pitch.
