Hosts:

The Mediterranean pine engraver beetle breeds in a large number of pines throughout its natural range. Indigenous European pine hosts include Canary Island pine, Calabrian pine, Austrian pine, maritime pine, Italian stone pine, Scotch pine, and a form of mugo pine. Several North and Central American pines that have been planted in areas where this insect is native or has become established, including Coulter pine, Caribean pine, shortleaf pine, Monterey pine, Mexican weeping pine, and Eastern white pine. Occasionally, maturing beetles feed in Douglas fir, Spruce, Fir, and Cedar. However, the Mediterranean pine engraver beetle does not breed in hosts other than pines.

 

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

 

Threat:

The Mediterranean pine engraver beetle is capable of killing trees under stress, especially moisture stress. Its greatest significance would be in areas where plantations have been established under conditions that are not always favorable and in natural forests where drought and other stress factors are common. Many North American pine forests occur under these conditions including much of the important pine growing regions in the western United States and Mexico. Economic losses due to tree mortality will vary based on location and degree of tree stress.

 

Distribution:

The mediterranean pine engraver beetle is not known to occur in Indiana.
