White pine weevil (Pissodes strobi, Peck.) is a native forest insect pest in the Pacific Northwest of North America that attacks species of spruce (Picea spp.) and pine (Pinus spp.). Young Sitka spruce [Picea sitchensis (Bong.) Carr.] trees are particularly susceptible to weevil attack. Pockets of naturally occurring Sitka spruce resistance have been identified in high weevil hazard areas in Cited by: 7.   The life history of the Sitka spruce weevil, Pissodes sitchensis Hopk., is described. Adults overwinter in duff at the base of trees and emerge Cited by:

  Pissodes approximatus Hopkins () is a junior subjective synonym of P. nemorensis Germar (). The conspecificity of these entities, traditionally considered distinct based only on distribution and slight morphological differences, is corroborated here with comparative studies of ecology, behavior, and by: Pissodes yosemite Hopkins, Pissodes schwarzi, the Yosemite bark weevil, is a species of true weevil in the beetle family Curculionidae.
