I know this is an older topic, but I have a follow up question, and request for help from it.
I know I have found an article in the past about why oranges (and other citrus) should only be fed to breeder roaches, due to the what the acid in the fruit turns to and that the roaches have no way to expel that from their bodies, however it is used for the formation of the oothicas. So at breeding age it is helpful for the females. The acid converted form is also not good to be fed to reptiles. Perhaps gout related?
ANYWAY! My ability to properly google and refind this information is failing and I'd love if anyone is able to help me find this article again!
I'll keep looking too, it was a good article and put it into good perspective.
