RE: Therese Bugnet

Apparently there are different kinds of borers, and that one kind
does like the rugosa type roses better (which Therese Bugnet is). 
One book implies that some can "attack" the tips, where as other
borders enter at a cut or wound.

Have you seen any larva in these hollowed out canes ?  You might not.
Be sure to burn the bad canes, (recall my sister had to keep cutting
till she reached good wood.) and seal the cuts. One rose stem girdler
is spiral just under the bark, sometimes causing the cane to swell
and break.

You might take it to your extension office and/or their Master
Gardener.  Would like to hear back when you find out.
