Konasdad. I think that your queery needs some elaboration. It is not the uncapping of unprocessed food that causes the dynsentry, I don't think that the bees will cap any sugar syrup that has not been reduced to the moisture content of their honey, which is around the 18% level. I could be wrong, but I hear something wrong with what you are understanding. Recount your question, make it more clear what your need of understanding is.
If the bees have food that is not of a certain moisture content, i.e., the moisture content of honey, then they are ingesting something that their bodies have to work further for them to use it as a viable long term food, i.e., wintertime.
Your question needs answers, no doubt about that. I await comments from our friends on the forum too that can provide good input, something that is easily understood. Have a wonderful day, await input, valuable answers. Cindi
