With the end of the year comes Top 10 lists.

The brown marmorated stink bug has the dubious honor of being named the 2012 Most Unwanted Invasive Pest by the Illinois Cooperative Agriculture Pest Survey Program, according to a news release.

Illinois growers have kept economic injury low due to low stink bug populations and intensive management programs.

Nevertheless, BMSB has spread substantially during the 2012 growing season, according to the U.S. Department of Agriculture.

The warm Midwestern fall allowed two generations rather than one to be produced during one growing season, resulting in a larger number of overwintering bugs.

The brown marmorated stink bug has become endemic to many parts of the Northeast, where it has devastated crops.

It has a wide host range, feeding on everything from stone and pome fruit to soybeans and field corn.

In the fall, BMSBs aggregate, forming large masses that seek refuge in houses and other buildings as well as dead trees.
