Sounds like the title to a really bad horror movie, now that I read it. I wonder who would play PMS?
I am responsible for teaching a section on bee diseases this weekend, and I've put together some slides and done some studying. I am looking for some input and words of wisdom about brood diseases.
First, it occurs to me that what is actually sacbrood may often get labelled as EFB. It seems to me that brood diseases that are not American Foulbrood (which is really rare in these parts so far as I can tell) automatically get labelled as EFB in practice by lots of beekeepers. Anybody think that's right/wrong or have any relevant thoughts?
Second, it occurs to me that a lot of folks may confuse the later stages of varroa mites with a brood issue. Any thoughts on that? And, other than telling people to look for mites, does anybody have any guidance about the differences in how frames look between: (a) a PMS meltdown vs. (b) a EFB or sacbrood issue?
Also, it seems to me that a severe mite problem could actually cause sacbrood to get out of control. Is there any study indicating that mites spread sacbrood virus. I've done some reading that indicates that PMS can look like sacbrood, but sacbrood itself may not be there in those hives, even when it sorta looks like sacbrood.
Finally, it is my opinion that none of these things are worth treating. If its AFB (and it hardly ever is around here) you are supposed to burn the frames under State law, so that's what I plan to tell the newbees. I also think that most beekeepers around her actually do burn any frames with AFB, which may be why there's so little AFB around here (also it helps that there's hardly any big commercial beekeepers). There's no treatment for sacbrood. If I have a hive that is really struggling with EFB, it either needs get better or be requeened, IMO. Any other thoughts?
Basically, I'm a beekeeper who is about to try to teach this stuff, and I've had a few issues here and there in my own hives, but not many brood disease issues. Any general words of wisdom for newbees about brood diseases are welcomed.
