I read with interest the writings of Adrian Wenner and his findings
of collapse of colonies due to Varroa due to heavy infestations of
Chalkbrood.
 
The thought occurred to me that I have seen heavy infestations of
Varroa on my bees with six or more mites on each bee in the later
stages of infestation.  Is there the possibility that the adult mite
makes it impossible for the bees to enter the cells due to increased
mass and therefore restricts normal cleaning behavior resulting in
Chalkbrood.  Lets face it, if I suddenly found myself humpbacked, I
might not fit into a body sized cavity either.
