Thank you, Peter.  I would expect some brood kill.  I believe the 
recommended rate from Finland that I've used with excellent results 
is 4 ml per bee space (the Greek study used 5 ml) but perhaps this 
difference does not affect the results much.  I would also apply only 
one treatment - has been very effective for me and I've read repeated 
treatments can cause queen problems.  Perhaps this explains the Greek 
observations of 4 months of brood problems.

I have a couple of other options.  Treat with sucrocide which I did 
not find effective 2 years ago (and I thought I saw decreased brood 
rearing).  Or wait until November and treat then.  It would be useful 
to see how the bees from my queen cope with varroa pressure...
