What is the
Hemlock Woolly Adelgid?
HWA (Adelges tsugae)
is an invasive exotic insect that attaches to the base of
the needles and feeds upon essential nutrients, eventually
killing the tree. It attacks the Eastern and Carolina Hemlock
(Tsuga canadensis and Tsuga caroliniana), which
are both abundant in this area. The Hemlock Woolly Adelgid
has attacked trees in East TN since 2002. Blount, Sevier,
Monroe and Knox Counties currently have infestations.
If infested trees are left untreated they will almost certainly
die.
What
are the signs of HWA?
· White cottony masses found on the
underside of small twigs.
· Needle loss and thinning foliage.
· Trees are a grayer shade of green than healthy
trees.
Can
my trees be saved? Yes!
As a result of years of research on HWA, nicotine-based chemical
insecticides have been found to be the most effective treatment
options.
