Question:<\/h3>\n

Some of my raspberry canes are breaking off, this is happening to the flourocanes. When I cut into the cane, I find a white segmented worm 1\/4 – 1\/2 inches long. I’ve had cane borers in the past, but the row around the cane is very obvious. I don’t have that here. What may this be?\u00a0<\/strong><\/p>\n

I conferred with our insect and raspberry experts and it sounds like it could be a few different things: crown borer, red-necked cane borer or cane maggot.<\/div>\n

It would be good to know at what height the canes are breaking off, to help with the diagnosis.\u00a0 Red-neck\u00a0cane borer usually shows a distinct swelling near the base of the cane. Crown borers usually cause wilting and marginal necrosis of the leaves, due to damage to the vascular system.\u00a0 It may also be raspberry cane maggot; the damage is similar to cane borer without the girdling\u00a0bands, but the cane tips usually wilt and turn black.<\/p>\n<\/div>\n

Please review the factsheets below to see if it matches what you are seeing.<\/p>\n
