As there seem to be two alternative approaches under discussion - breeding
Varroa resistant bees, versus modifying the brood nest to create small cells
that in some way decrease Varroa
reproduction - and both appear really to be getting somewhere - could we
lurkers press for more information/comment on what mechanisms are believed
to be triggered in each approach.>>
The first thing I noticed when I started downsizing bees was the
appearance of bald brood, which I'd never seen before; some pupae were chewed out
altogether. Not everyone sees this, but I'm not the only one by any means. So
that's something to look at. Someone in the UK - I forget who - was breeding
for mite damaging behaviour, apparently with some success; I don't know where
he is with that now. I have a strain which has been bred for a degree of
resistance (not by me), and I've noticed a high proportion of light coloured
mites falling out, which I'm told are unlikely to be able to breed. So there are
some possibilities. Right now, the hive with the lowest mitefall is also the
one with three laying queens, but somehow I doubt whether that's relevant.
