Background

The Brown Marmorated Stink Bug (BMSB), Halyomorpha halys (Stål), is an exotic pentatomid species native to Asia. Pennsylvania State University Cooperative Extension first found specimens in Allentown, Pennsylvania, in 1996.

In 1999, a specimen was found in a Rutgers University blacklight trap about 30 miles east of Allentown in Milford, New Jersey. Since that time, specimens have been identified in 29 states, primarily in the Mid-Atlantic region but with additional populations in Oregon and Southern California. Midwestern populations of BMSB were found in Ohio in 2007, Illinois in 2009 and in Michigan in fall 2010. As with many other invasive species, the distribution is likely spread wider than reported.

What crops are affected?

Brown marmorated stinkbug has a host range of over 300 plants including many agricultural and ornamental crops. Feeding damage has been recorded in high value specialty crops including tomatoes, sweet peppers, raspberries, apples, peaches, pears and cherries as well as damage in corn and soybeans.

Status in Michigan

In fall 2010, BMSB was detected in Michigan for the first time. No additional specimens have been found in Michigan as of May 30, 2011.
