The Mediterranean Pine Engraver (Orthotomicus erosus) is a pest of pine trees. This pest usually attacks recently fallen or cut trees, but can kill live trees, especially those stressed by drought, fire or wind. It is native to Europe, northern Africa and Asia and was discovered in California in 2004. Surveys are conducted because of the presence of potential host material in Wyoming and because O. erosus is commonly intercepted on imported wood packing material. To date, it has not been found in Wyoming. Two hundred seventeen traps have been placed throughout twenty-three counties in Wyoming since 2008.
The Mediterranean pine engraver survey is conducted by the Animal and Plant Health Inspection Service, Plant Protection and Quarantine. A Lindgren funnel trap with host attractant is placed on or near the host plant from May until September. If suspects are found they are sent to a regional entomologist for further identification.
