Is There Genetic Resistance to the White Pine Weevil in Pinus Strobus?

The importance of eastern white pine (Pinus strobus L.) to the forest economy of the Northeast is well known, That the white-pine weevil (Pissodes strobi Peck) is the major cause of the declining production and use of this species also is well known, And most people would agree that the development of weevil-resistant strains would be the most economical means of restoring white pine to its former high place among Northeastern timber species. The initiation of an effective intra-specific breeding program for weevil resistance in eastern white pine depends on the finding of resistant trees. A question of paramount importance is whether there are, in fact, resistant specimens of P. strobus. Few studies have been directed toward the detection or selection of resistant trees, and so far no individual trees have been proved to be resistant.
