Tiny Holes Bored Into Cut Stem- Is This A Pest?

In a row of well established rose bushes the first died a year ago and now it looks like the second Bush may also. I cut off the affected stems thinking it could at least keep from spreading to the 3rd bush(there are re 7 in a row). This was a few weeks ago as soon as I noticed the condition. The bush doesn’t look any better and even has a few black fungus spots on the canes but I didn’t think cutting would cure it. Yesterday I took a closer look at the cut areas and saw a single hole in each stem I cut. Looked at the first bush and it has older holes in it.
