Mark record


Ambrosia beetles are a serious menace to commercial timber-producing areas. Their infestations result in degraded lumber and various hidden costs, both in the processing of infested material and in the rejection of export-bound products. In British Columbia, in 1975-76, the loss because of ambrosia beetle damage was estimated by Western Forest Products Laboratory, Vancouver, B.C. to be $7 million.

The economic importance of these beetles is closely related to man's forestry practices. Dry land sorting and storing of enormous amounts of wood creates conditions that can be ideal for brood production, increasing the danger of damage as well as producing a larger population of beetles which will become next year's pests.

The most effective way to prevent damage from occurring is by hot-logging (rapid utilization) and fast processing, methods that deny the beetles' wood supplies suitable for breeding.
