Dee, I see sometime ago on beesource.com that you or somebody else was to check the reproductive rate of varroa in combs of different sizes, is that experiement now completed? I compared the varroa reproduction rate between two hosts: workers reared in worker cells and workers reared in drone cells and strangely, mite reproduced much less on workers reared in drone cells! this is only true in Apis mellifera, in Apis cerana the difference is not significant.
