While I was doing some spring pruning and clean-up in my garden I notice one of my old and usually very vigorous Ragusa roses was looking rather wimpy. On closer inspection I discovered there was some kind of insect boring staight through the canes! Help! What can I do to save my rose? How about this bug, will it eat other shrubs?April 18, 2010 at 8:27 pm #29384margaretKeymaster
Was trying to find some photos online to see if they ring a bell. Have a look here first and say whether this is like what is up with your rugosas:

With a little more web research I found some advice to try.The cane boring insects on my roses bore straight down the center of the canes leaving them hollow like a straw. The advice I found (sorry,forgot to copy a link)was to cut back the affected stems until you reach a solid end then paint it with White Glue. It was also suggested that the ends of canes be painted with glue every time you prune to keep the insects out. I’m from Seattle and am not sure the White Glue will hold up in the damp spring weather. I haven’t seen the insects yet but found damage on another shrub rose “Mutabolis”. Now I’m concerned about my Raspberries. Any ideas what the insect looks like, how to get rid of it? Thanks
