The white pine weevil, Pissodes strobi Peck, is a pest of young spruce, plantations in British Columbia which seriously hampers forest regeneration. Weevils kill year old spruce leaders resulting in growth reductions and poor stem form. As accumulated heat is required for completion of the weevil's life cycle, a degree-day based hazard rating system for the weevil could be . The white pine weevil (Pissodes strobi Peck) is an important insect pest in the Pacific Northwest that attacks the apical stem leaders of spruce (Picea spp.) causing damage to tree form, growth.

Most scolytid bark beetles have specialized feeding habits, and attack one or a few closely related host-tree species,.This probably resulted from adaptive radiation when colonizing many niches provided in part by a variety of trees secondary chemicals,, and from a long evolutionary association of bark beetles with their host by: Quality white pine lumber may be in demand 30 years from now while white spruce dimension lumber may not. Good quality trees left after thinning can be harvested for high value products later. Most harvests produce multiple products, sometimes as many as six different products from a .
