My question is, I have a boxing glove Cholla and it has some kind of problem where parts are dying. Pruned it today and in one spine there was a brown center which makes me wonder that it has some kind of bug. Could this be a cochineal bug and how to get rid if it. I am in Chandler, Az. It has been in the ground for 2 years and I love it but don't want to loose it. I walk in our neighborhood and I haven not seen one like it.

These plants are located in several locations in Black Canyon City Arizona. I have one that I got from a piece that I got from a friend. It roots easily and grows nicely. At least on the pieces I have handled it's much easier to use your bare hands and carefully grab between the areoles. The spines are short.. From the mammilata part of the the name.. (its a nearly spineless form of C. fulgida...) Also mine tends to crest...

this is a nice looking cactus, but one of the most horrific in terms of handling in my yard of cacti... can't use gloves of any kind... the spines will find their way through. And the plant breaks apart easily with the lost pieces seemingly magnetically atttracted to my body- yeouch! Had to eventually get rid of this plant.

This monstrose form of Cylindropuntia fulgida is the "mammillata" variety that has monstruosed and will usually end up cresting.
The full latin name is Cylindropuntia fulgida var. mammillata f. monstose cristate
