Abstract

<i>Pissodes alascensis</i> Hopkins ranges throughout interior British Columbia and into Yukon Territory. Spruces are preferred hosts. Weevils reared at 1,300 ft. elevation had a l-year life cycle, but most of those reared at 4,000 ft. elevation had a 2-year life cycle . The latter passed the first winter in the larval stage in the inner bark and the second as callow adults in pupal chambers in the wood. Emergence ranged from the end of May into September.
