[NAFEX] AACK! Persimmon borers(?!)

After grafting a few persimmons in the nursery beds this morning, I 
took another turn around the orchard to survey the damage and 
recovery, such as it is, of the freeze-damaged pecans & persimmons.
Most appear to be re-leafing, though some of the young 3-5 yr old 
grafted American persimmons appear to have killed back all the way to 
the main trunk.  At least a couple may be total kills, and closer 
inspection of those revealed the characteristic little pale, 
toothpick-sized frass tubes, sticking out from their trunks, that I 
presume are associated with borers of some sort.
Fortunately, I have 'back-ups' of these varieties, or gathered 
dormant scionwood back in Feb/March, so they're not totally lost to 
me, but it is distressing.

Does anyone have any info or recommendations on control/prevention 
strategies to diminish infestation on the remainder of my trees?
