| More than 95 percent of the mature Fraser firs in the park are dead, robbed of their lifeblood and poisoned by a toxin injected by the adelgid. |
|
| Over the past thirty years, these unique forests have been decimated by the balsam woolly adelgid, an aphid-like insect introduced from Europe. |
|
| In addition, a species related to HWA, the balsam woolly adelgid, has already killed about 90 percent of the mature Fraser fir trees in the Smokies. |
|
| The woolly adelgid has chewed its way up the crest of the Appalachian Mountains from the Carolinas to Canada. |
|
| The reason being, is that the bitter cold kills the hemlock's adversary, the hemlock woolly adelgid, a tiny insect pest. |
|
| Another tree is being attacked by an alien insect, the hemlock woolly adelgid. |
|
| In some parts of the Northeast, woolly adelgid and aphids are serious pests. |
|
| But around 1953, the hemlock woolly adelgid was discovered on Eastern hemlocks at Maymont Park. |
|
| Since the adelgid did not attack red spruce or hardwoods, its impact on the timber industry would be minimal. |
|
| At high elevations in North Carolina, the balsam woolly adelgid seems to be the culprit in the highly visible death of Fraser firs. |
|
| Even though the pests were temporarily vanquished, there is no ongoing funding for hemlock woolly adelgid control of this magnitude. |
|
| Eastern hemlock is currently being threatened by the hemlock woolly adelgid, a defoliating insect. |
|
| Sasajiscymnus tsugae has been reared as a predator that specifically targets the Hemlock Woolly Adelgid, a very destructive pest of the Eastern and Carolina Hemlock. |
|
| The hemlock woolly adelgid is responsible for the death of large numbers of hemlock trees from the Carolinas to New England, and it's causing lots of problems. |
|
| The latest threat to the forest emerged in 2002 when another Asian woolly adelgid that kills hemlock, another keystone species of the forest, entered the park. |
|
| One concern raised was the potential effect the hemlock woolly adelgid, an insect pest, would have on the 8 percent of the forest that is Eastern hemlock. |
|
| Whether the task is protecting Fairmount Park hemlocks against the woolly adelgid or promoting funds for greenway acquisition, DCNR have experts who can, and will, help. |
|
| The insect is the Hemlock Woolly Adelgid and in the eastern United States it has a very large food supply and no natural predators. |
|
| Severe winter cold helps reduce adelgid populations and slow their spread, so the recent trend toward relatively mild winters is actually facilitating the adelgid onslaught. |
