> Adult bees of inbred resistant strains detect diseased larvae mostly in
their eighth or ninth day of larval
life, when they have died in their sealed cells but have not yet formed
infective spores,
Back in the 1980's I successfully bred bees that would do this very thing.
You could put a brood box reeking with AFB on top of them and they'd clean
up every trace in a few days. But some spores would remain, and if those
colonies got nutritionally stressed, a cell or two of AFB might reappear.
