How common is Viburnum Borer?
Found in the Midwest?
Treatment effective?
A pest of all Viburnum, or only select species, like High-Bush Cranberry?
It's different from Viburnum Beetle, which I remember reading in American Nurseryman was a problem out East, working its way West?
I'm consulting a client on a tree-care contract, and this pest was new to me. Always thought High-Bush Cranberry self-destructed due to poor pruning, and trunk rot, but maybe its borers...
