Hi Randy

Interesting, I have never paid much attention to chalk brood myself, but 
I hear a lot of complaints about it among some strains of AMM, my pet 
theory at the moment is that this is due to a flaw in the selection 
criteria used, but I would like some guidance on where to research the 
mechanisms for resistance that you mention.
