Is My Blackberry Infested with Blackberry Cane Borers?

Hello,

While pruning my thornless blackberry plant, I noticed these galls on its canes.

FYI, my plant is two years old. I live in southern Quebec. 2/3 of the plant was cover with snow almost the entire winter.

This gall is located at the bottom of the cane:

This one is located in the middle on a different cane:

I only have two strong big canes and a skinny one. Can someone explain exactly what they are, and if I should do something about them?

Ghadames. It sure looks like cane borers to me. We are a long way apart but appear to have a similar problem. I posted a picture of my Natchez blackberry a few days ago. Yours looks similar. What variety of blackberry grows that far north? There are many more experienced people than myself that could be more definitive. Good Luck, Bill

I don't know what type of blackberry it is. It was given to me by my mom's friend. All I know is that it's thornless.

Last summer, these cane borers attacked my raspberry plants. I was able to cut off the tilted tips and save the canes. The source of the problem was a small sick tree nearby that was infested with aphids and other insects. I saw borers too. After I removed the tree, no more tilted tips.

They might have laid eggs on my blackberry canes, but I did not see any tilted tips. I check my plants almost everyday during summer.
