All, just catching up on this  conversation. The best knowledge I know 
about this is from Harbo,  J.R., and J.W. Harris. "Effect of screen floors on 
populations of honey bees and  parasitic mites (Varroa destructor)." Journal  
of apicultural research 43.3  (2004): 114-117" in which they conclude 
screens decrease ingress of mites into  open brood cells which, of course, is 
necessary for mite reproduction. I don't  think the "drop through the scene"  
hypothesis is well-supported.
