Description:
An evaluation was made in 21 seed production areas and 1 seed orchard in Region 1 to identify the primary insect pests and to
assess amount of injury caused. Cones from Douglas-fir, grand fir, western larch, lodgepole pine, ponderosa pine, and western
white pine were collected periodically and examined. The primary insect species observed were western spruce budworm
on Douglas-fir, grand fir, and western larch; midges on Douglas fir, grand fir, western larch, ponderosa pine, and lodgepole
pine; coneworms on Douglas-fir, grand fir, western larch, and ponderosa pine; and the Douglas-fir cone moth on Douglas-fir.
