Brown Marmorated Stink Bug
The brown marmorated stink bug (BMSB), a relatively new invasive species to Oregon, may be entering people's homes this fall as it seeks winter shelter inside buildings. Until 2010, it was not known to be established in Oregon outside of the Portland metropolitan area, although a few specimens had been found in Salem and in Sandy. As of 2011, BMSB established in Clackamas, Marion, Multnomah, Polk, Washington, and Yamhill counties. BMSB has recently been detected, but not known to be established, in Gilliam and Benton counties. A current US distribution map, which includes the positive Oregon counties, is available on the Pest Tracker website. BMSB is considered a major agricultural pest in Asia, attacking many crops. It is a significant agricultural pest in some areas of the eastern US, attacking tree fruits, peppers, tomatoes, corn, berries, grapes, soybeans, melons, and even damaging young trees by feeding through the bark.
The public can help the Oregon Department of Agriculture determine the distribution of this pest by calling the Oregon Invasive Species Hotline (1-866-INVADER) to report possible BMSBs found outside of the areas mentioned above. In order to confirm a report ODA requires a specimen. The hotline has details on preserving and sending suspect BMSBs. Samples should be sent to Barry Bai, Oregon Department of Agriculture, Plant Division (IPPM), 635 Capitol St. NE, Salem OR 97301.
