As of March 2013 the state of Massachusetts announced a quarantine will be established in Berkshire County, in order to stop the spread of the invasive insect species: Emerald Ash Borer, Agrilus planipennis.

This tiny, shiny green exotic beetle hails from Asia and is rather pretty.

EAB was first detected in Massachusetts in Dalton in August of 2012.

Massachusetts is the
eighteenth state discovered to have EAB within its borders.

The adult beetles nibble on ash foliage but cause little harm there. The damage is done by the larvae (the immature stage) feeding on the inner bark of ash trees, that disrupts the tree’s ability to transport water and nutrients and eventually kills the trees.

This beetle brings a very serious threat to the ash trees in our area, for this reason the officials at the Department of Conservation and Recreation (DCR) decided a county-wide quarantine is the best chance of slowing the spread of this destructive insect.

After the a regional survey was completed around the Dalton/Pittsfield area, five trees were
found to have EAB larvae present. These trees are located within a 1.5 mile radius of the trap
where the first EAB beetle was detected in August 2012.

regulated area, including all hardwood firewood (any piece of wood smaller than 48”), all ash
nursery stock, and any ash lumber that has not been treated. Proper wood treatments include
the removal of bark and half an inch of wood, dry kiln sterilization, fumigation, and heat treatments.
