Small wet areas on the bark in early summer may indicate young borer activity. This borer does not seem to distinguish between weak and healthy trees. Dogwood borer, Synanthedon scitula, prefers flowering dogwood (Cornus florida) as its host. Infestation levels of Synanthedon scitula on flowering dogwood (Cornus florida) in commercial nursery, urban and forest habitats in eastern and middle Tennessee were measured during 1987 and 1988.

A few weeks later, a new generation of beetles emerges from infested plants to continue the life cycle. However, it requires a 2-year life cycle in Minnesota (Ruggles 1915) and a 3-year one is implied on blueberries in New Jersey (Driggers 1929). In your case, clip off the infested limb(s) below the injury now and spray the trunk and limbs of the tree with any landscape insecticide (click for sources) in spring. In young trees, the crown is attacked, resulting in wilting and die-back. The species specificity of the trinary and binary blends was high.
