> It almost sounds as if an apian ethnic cleansing is at hand.
That is a little harsh Allen. The UK has native honeybees and more people these
days would like to cherish, preserve and improve them. The rush of beginners
into the craft in the UK comes with a bias towards low chemical approaches,
local food production and conservation so many are receptive to the view that
native is best. However at the same time the demand for coloniesand the
background of a few difficult seasons means that many have turned to suppliers
who satisfy the demand from professional breeders abroad. The end result of all
of this is that the refuges of pure Amm are under threat as never before, to a
large extent from a well-meaning widely scattered army of beginners desperate
for bees. There is quite a lot of interest in doing something to preserve
remaining stocks - far from ethnic cleansing and more like saving an endangered
type of honeybee.
Why do I say endangered when Murray says that he has thousands? Murray's bees
are far from pure. There may well be a progression back to darker types once
exotic introductions have stopped for a few years, but what you get after that
is indeed a mongrel stock of highly mixed genetics. I'm keen to find reasonably
pure local Amm stocks for a breeding project but I'd never have considered
asking Murray - or am I wrong?!

The combination of mixing up the genetics and the low levels of selection will
make any strain decline in performance. If the breeding effort elsewhere was
also applied to any strain in the UK (including Amm) but in a location where
mating could be controlled then you would get the bee you select for surely?

Two different things here. Adding a genetically *very* different strain (as are
Amm and Amc) will give the temporary fix of hybrid vigour at the expense of
long-term stability. You get the same thing with plants. In the long run the
effect is negative in my opinion. The other reason for the good performance of
your imported bees last year would be their initial high health status and the
fact that they were given fresh foundation.
I don't see this as being about loud voices and funding - last year's imports
received a lot more funding than has gone into honeybee conservation here which
has always been a small-scale amateur and sometimes amateurish business.
A lot of the bad press that Amm get here may be due to the fact that hybrid
stocks look like Amm. Selected, bred Amm can be gentle and productive - but
their hybrid derivatives cannot easily be distinguished from the parent types.
Italians and Buckfast come with a colour-coding system that make crosses
obvious.
all the best
