Hosts:

The golden-haired bark beetle attacks a number of pines within its natural range. These include Canary Island pine, Aleppo pine, Calabrian pine, Austrian pine, Cyprus pine, Maritime pine, Italian stone pine, and Scotch pine. North American pines that have been reported as hosts include Slash pine, Monterey pine, eastern white pine, Montezuma pine, and Mexican weeping pine.

 

Commodities Affected:
Forestry and Natural Areas, Nursery, Ornamentals, and Turf

 

Threat:

In Chile, where this bark beetle has been accidentally introduced, it has killed 1-2 year-old seedlings of Monterey pine, mostly in naturally regenerated (as opposed to planted) trees. There, the golden-haired bark beetle has been reported to reproduce in slash as well as young Monterey pine trees, and through their maturational feeding cause up to 10% mortality of newly established pine plantations. In South Africa, the golden-haired bark beetle is known to introduce bluestain fungi in the genus Ophiostoma to the wood through their galleries, and it also transmits root pathogens in the genus Leptographium.

 

Distribution:

The golden-haired bark beetle is not known to occur in Indiana.
