Abstract

White pine species and hybrids are being tested for inherent resistance to the white-pine weevil. First-year results offer hopes of finding or developing resistance in this group. Pinus monticola had a low level of weeviling, while the hybrid between P. strobes X P. wallichiana was heavily weeviled. There is evidence that individual P. strobus with acceptable levels of weeviling can be located in natural populations.
