Invasive beetle found in Berkshires

Officials work to gauge spread of pest linked to deaths of millions of ash trees across US

The emerald ash borer, an invasive beetle that has killed tens of millions of ash trees across a wide swath of the country, has been found in Berkshire County, its first appearance in Massachusetts.

The tiny but destructive insect, which has caused billions in economic damage since it was first discovered in North America in 2002, was found Aug. 31 in a trap in Dalton, a small town near Pittsfield. Tests confirmed last week that Massachusetts has become the 18th state to encounter the feared pest.
