Damage |
Red oak mortality has been observed for the past several years (2001). Drought, shallow soils, hypoxylon canker, certain insects, and other factors have lead to this decline complex. |
| 0007076 |
Damage |
It is at outbreak levels in the area and characteristic signs of attack include "wet spots" where young larva are feeding under the bark. |
| 0007077 |
Adult(s) |
When adult red oak borers begin to emerge in late June, populations are so high that it is easy to find mating pairs on understory vegetation and on the trunks of oak trees. |
