Mediterranean Pine Engraver - Orthotomicus erosus

Established populations of the Mediterranean Pine Engraver (Orthotomicus erosus) were discovered in the United States in 2004. This Eurasian bark beetle is native to the pine (Pinus) growing areas of Europe, Northern Africa and Asia.

Sample Areas were developed using the Susceptibility Surface. A total of 1,000 sample areas were assigned to one of four risk categories. Relative certainties were assigned to each category in order to create increasing plot intensifications for increasing risk stratums.
