Dee,
Picking figures from a table in the back of Bailey's lecture. From all
localities in the county of Hertfordshire (UK) over a 5 year period there were an
average of 5.1 colonies per site and 6.1% of them were infested with A.woodi.
During the same period the 18 apiaries operated by the Rothamstead
Horticultural Research Station having an average of 14 colonies per site had 29% of
them infested.
In the county of Oxfordshire a few years later the overall density was 4.8
hives per site and 5.4% were infested whereas in 1 commercial apiaries
averaging 29 hives per site there was 40% infestation.
This was some years ago and I have no idea what size foundation was being
used then.
He doesn't mention propolis and I doubt if its antibiotic and anti viral
properties were recognised then and people were trying to select for bees that
gathered less propolis. I think some still are, despite its value as a bye
product of the hive.

Some how I am not seeing this as written about in the bees
I keep that are smaller. But then they have more access to
varied propolis/resins from more varied floral sources,also
that is critical to broodnest sterilization and injested by
the bees themsleves. So am I wrong in assuming that the
bees looked at by Bailey were on enlarged combs FWIW being
maintained? What were the parameters of the bees looked at
for living/maintenance? Ferals, or domesticated and then
what type?
