From the San Francisco Chronicle:

An insect with a voracious appetite, no domestic natural predators and a taste for everything from apples to lima beans has caused millions of dollars in crop damage and may just be getting started.

The brown marmorated stink bug, a three-quarter-inch invader native to Asia, is believed to have been brought first to the Allentown, Pa., area in 1998. The bug began appearing in mid-Atlantic orchards in 2003-04 and exploded in number last year.

This spring, stink bugs have been seen in 33 states, including every one east of the Mississippi River and as far west as California, Oregon and Washington.

"All that we do know for certain is that a tremendously large population went into overwintering in fall 2010. So, if they survived, there could be a very large population emerging in the spring," said Tracy Leskey, a research entomologist at the U.S. Agriculture Department's Appalachian Fruit Research Station in Kearneysville W.Va.
