Any of you want to fathom a guess?
Not taking feed is classic of nosema cerana. Hives slowly die off as you
decribe.
Using all stores and dwindling with missing bees can mean queenless.
If a small batch of young bees and a
queen only left then welcome to the world of CCD. What you describe is more
common that a large amount of brood and a small group of bees and a queen
from my observations of claimed CCD.
I have seen a whole load go from fstrong to dead with missing bees in a
couple weeks. We suspect the neonicotinoids in these cases but have no solid
proof.
