The Gypsy Moth – They’re Back! AKA Lymantria dispar (Linnaeus)
The gypsy moth was accidentally introduced into Massachusetts in l869.
By 1902 this pest was widespread in the New England states, eastern New York, and regions of New Jersey.
The gypsy moth was first detected in Luzerne and Lackawanna Counties in northeastern Pennsylvania in l932.
Pennsylvania’s infestation progressed south and westward following the mountain ridges.
During the late 1970s and early l980s the infestation advanced into Hudson Valley Counties.
Heavy defoliation and subsequent tree mortality have occurred along mountain ridges in forests comprised primarily of oak. It is the most important insect pest of forest and shade trees in the eastern United States.
This year we have seen pockets of heavy infestations with some of our customers. Here what to look for:
