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.
