Subject: Re: girls on small cells, regressing bees
Thanks Erik,
I read about early plans to
cross Carniolan and Capensis as a varroa
resistant strain, in Europe, but I haven't heard anything ever
came of it. I am fast becoming fascinated with bee breeding,
and genetic heredity in
general, what sort of percentage of new blood did you have to
introduce to
create such a lasting effect? Or do you continually add new bloodlines?
I
posed a question on Beesource forum about how different strains
of bees
really are. If they all interbreed with ease aren't they all
carrying the same genetic information, just expressed differently
according to where they are?
Re 'regressing bees' I've chosen
the smallest drawn comb I can find. I'm
going to make five 5 frame nucs in early Spring, one drawn comb
flanked by
full sheets of 4.9 foundation. I'll feed honey watered down to
stimulate brood rearing, and hence the need for cells. I'll feed
Pollen or protein too, any ideas? I'll keep good ventilation,
but insulate or perhaps artificially warm those colonies. The
remaining brood on the buggy comb I'll combine with the colonies
I am not downsizing this year. (It is awful to realise there
were so many other casualties from our treating for varroa with
pyrethroids, it's clear to me now why Dee maintains 'shakedown'.
I was intending to Snelgrove my colonies onto 4.9, and may try
that with another colony anyway. Get the colonies away from the
poison in the wax, and perhaps the ecosystem we call a beehive
can restabilise itself. I wonder if pollen mites (for example)
have been completely wiped out) As soon as all frames are drawn
and laid in I will Snelgrove the nuc with full frames of 4.9
foundation, choosing the best drawn 4.9 comb as my central frame.
I'll probably cage the queen in at this stage too, depending
on drone production. I forsee it getting extremely interesting
about then, especially if the rape is in flower, and may have
to abandon Snelgroving the nucs in favour of larger broodboxes.
This would be a pity, as I want to propogate from the best adapting
colonies, and feel that getting queens raised from an already
downsized colony/nuc is important. Hopefully 3 day inspections
will keep me on top of things. I don't expect any honey from
these colonies next year, but they must provide comb, bees and
collect their own winter stores.
I need help with selecting
my breeders. Any thoughts on determining which
colonies will be the best for grafting from and which for drones?
Is there
anything other than dumb luck at work if I inbreed? I'm only
going to select for 4.9ers to start. How do I decide the best?
Seasonable E gards
