I'm packing up at the moment, as I'm moving shortly, so I don't have my ABC on hand. Really wished I hadn't packed that up in one of the dozen or so boxes full of books.
But I'm glad to hear no one is suggesting AFB. The black "scale" like object (shown in the bottom picture) had me a little nervous. Although in the picture it looks less like "scale" and more like goo. Could be the photo, but more likely it was my "oh ****" nerves that thought it was scale at the time.
I can extract some of the sickened larvae as if they are watery sacs. But my understanding was that most resemble the shape of a slipper or a canoe, i.e. the larvae of sac brood retain their shape, with oddly shrunken heads. The top photo appears to have larvae that deflated in the cell. I was seeing more of that then I was of white/brown/black sac brood larvae I've seen in photos before.
I really need to get better about disease recognition. I'm good at telling varroa and SHB infections, and have run into EFB and Chalkbrood once or twice in the past dozen years, but other than that I'm not good at spotting any other diseases. One could call it a blessing, but on the other hand since I haven't had any experience with it I know it will be a problem later. Other than reading over ABC and/or studying pictures, any suggestions on how to get better at disease ID? Particularly AFB.
