|Woolly Adelgid Update
The hemlock woolly adelgid (HWA) Adelges tsugae
was first described in western North America in 1924, and first
reported in the eastern United States in 1951 near Richmond, VA.
Hemlock Woolly Adelgid damages and kills Hemlock trees by sucking the
sap out of the small twigs. Once the sap is gone, the needles turn
brown, fall off, and the tree dies. Trees need their needles to
This pest started killing Hemlock trees in North Carolina and Virginia
and has now crept into South Carolina. The pestilence can be
identified by looking at the Hemlocks green twigs (especially on the
bottom side). Look for fluffy white looking pieces of cotton like
If you have Hemlock trees, call us to double check and have them
treated. This pestilence will most likely eventually kill all
untreated Hemlocks. Don't wait till it's too late to take action!
Research scientists using molecular genetics have recently determined
that several distinct populations of HWA occur in Asia and western
North America and we now know that HWA populations found in the East
originated from southern Japan. In their native range, these
populations of HWA cause little damage to the hemlock trees they feed
on as natural enemies and possible tree resistance has evolved with
this insect pest.
In the absence of these natural control elements in eastern North
America, this introduced insect pest attacks both eastern (Canadian)
and Carolina hemlock which are often damaged and killed within a few
years of becoming infested. HWA is now established from northeastern
Georgia to southeastern Maine and as far west as eastern Kentucky and
