On July 1, 2004 Clinton,
Essex, Rensselaer, Warren, and Washington in eastern
New York were added to the 43 counties in New York
under quarantine for pine shoot beetle. This is of
concern because Rensselaer County is adjacent to Massachusetts.
The pine shoot beetle (Tomicus piniperda) is an exotic
insect first discovered in the United States on a
Christmas tree farm near Cleveland, Ohio in 1992.
Since that time it has spread into twelve more states;
Indiana, Illinois, Michigan, Wisconsin, West Virginia,
Virginia, Pennsylvania, New York, Vermont, New Hampshire,
and Maine. The pine shoot beetle has been a target
organism for the Cooperative Agricultural Pest Survey
(CAPS) for several years and has never been found
in Massachusetts. This summer CAPS is surveying again
for the pine shoot beetle.
The pine shoot beetle feeds on all species in the
genus Pinus with its preferred host being Scotch pine
(Pinus sylvestris). Adult beetles feed inside the
new shoots stunting the growth of pine trees. Damaged
shoots flag (droop), turn yellow, and eventually turn
brown & fall off the tree. Damaged shoots will
have a round entrance hole (2-3 mm in diameter) surrounded
by pitch. For photos of the beetle and the damage
it causes read the fact sheet at: http://www.massnrc.org/pests/pestFAQsheets/pineshootbeetle.html
If you suspect you have seen damaged cause by the
pine shoot beetle, you can report it on the MA Introduced
Pests website or call the plant pests and noxious
weed hotline (617) 626-1779.
The pest alert is from the Massachusetts Introduced
Pests Outreach Project, a collaborative project between
the Massachusetts DAR and the UMass Extension Agriculture
and Landscape Program aimed at preventing the establishment
of new pathogens and pests in Massachusetts. Visit
