Ambrosia beetle degrade of sawlogs processed through the Vancouver log market in 1980/81 is calculated to be C$63.7 million. Similar losses can be expected in the future unless there are major changes in log inventory management. Gnathotrichus sulcatus was shown to penetrate Douglas-fir and western hemlock logs 3 cm and 8 cm respectively. The comparable figures for Trypodendron lineatum are 3 cm and 4 cm respectively. Factors that lead to the build up of ambrosia beetle populations in forest settings and processing areas must be identified to ensure maximum clearwood yield from logs.
