| In some parts of the Northeast, woolly adelgid and aphids are serious pests. |
| 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. |
| 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. |
| Since the adelgid did not attack red spruce or hardwoods, its impact on the timber industry would be minimal. |
| Even though the pests were temporarily vanquished, there is no ongoing funding for hemlock woolly adelgid control of this magnitude. |
| Over the past thirty years, these unique forests have been decimated by the balsam woolly adelgid, an aphid-like insect introduced from Europe. |
