Abstract

The pine seedworm, Laspeyresia piperana (Kft.), is a common pest in cones of Pinus ponderosa Laws. in British Columbia and may destroy up to 50% of the seed.

Moths emerge in May, mate, and lay eggs on second-year pine cones. Immediately after hatching, the larvae migrate to the centre of the cone and feed on seeds throughout the summer. In autumn, larvae tunnel into the cone axis to overwinter. Pupation occurs in spring.
