Hi to all on Biological Beekeeping
First, I want to say I have
been enjoying the discussion with you all and
especially Dave's interaction. Without it, it would be hard to
visualize
various concepts and how we all perceive them. As you can probably
all see,
we all picture the wordings in our minds a little bit differently,
so
discussion adds to greater understanding, so each of us can work
better with
our honeybees.
Dave wrote earlier pertaining
to what is a 'whole bee' selection concept.
Dave said, 'I have to dissagree on nature breeding as a 'whole
bee' it is in
fact minor changes over many generations that enable survivership'
Reply: This is excellently
put by Dave that in fact minor changes over may
generations enable survivership within our honeybees, but I do
select our
breeding stock based upon what we call a 'whole bee concept'.
Perhaps I should outline basically
what we look at in a hive for workerbees,
that one might want to use then, for production of drones later
and/or
queens.
We believe that beekeeprs should
look for and select honeybee breeder/drone
hives based on a whole bee theory of field characteristics. Since
we select
to the black side, because we have found more beneficial characteristics
on
this cold-weather side of the spectrum, I will therefore list
basically,
what we look for to offset the characteristics, of the yellow
hot-weather
side of the spectrum:
1. Colour.
2. Largeness of brood pattern during main honeyflows.
3. Lack of disease.
4. Lack of/low number of parasites.
5. Body uniformity.
6. Lack of crossbrace.
7. Body size.
8. Honey and pollen gathering capabilities, both main and out-of-season.
9. Colony defense.
10. Hours of flight.
11. Manageability (aggressiveness).
12. Robbing capacity.
13. Conformity of brood pattern during out-of-season and pre-flow
periods.
14. Cluster and fanning abilities.
15. Propolizing abilities.
16. Broodnest priming abilities during out-of-season and pre-flow
periods.
Now with the above, there are
various reasons for looking at these
characteristics both pro and con. We look for all within a colony,
because
we have found that to put a colony aside for and/or select for
only one or a
few attributes only can have detrimental consequences.
Dave also wrote about splits.
He said, 'We do not 'split' colonies as we
would have no control over the genetic make up of the queens
that would
result in the queen less have of the 'splits'.
Reply:
This chain of thought I do not follow! A colony that is divided
is a 'split'
colony or a 'divided' colony, and if one is practicing outbreeding,
to a
point, there would be no control over the drones, with which
the queens
would be mating.
This can be rectified somewhat,
with out-of-season breeding though, to
either the yellow and/or black side of the spectrum. Perhaps
Dave could
explain a little more here on his way (s) of making increase
in numbers for
understanding for me so I can follow his chain of thought better.
Dave wrote: I out cross regularly,
but certainly not everytime. Inbreeding,
'ie backcrossing' is just as useful a breeding tool as 'outcrossing'.
Backcrossing helps stabilize lines and 'fix' characteristics
that would
otherwise be variable.
Reply:
It is nice to see that Dave regularly out breeds his colonies,
but I am a
little bit puzzled by what he means concerning inbreeding as
pertains to
backcrossing.
To me inbreeding practices
are basically the usage of the same drone mother,
back to back in the field. This could also be put, as the selection
and
usage of the same queen mother, back to back, for production
of queens to
take to the field, as the drones are a direct compliment of the
queen in a
colony. I also would call the insemination of drones back to
it's mother,
which would be mating back to itself, the queen again being a
direct
compliment to the drone, and thus inbreeding.
I have never heard backcrossing
in general context refered to as inbreeding,
especially when open field mating is used. Nor have I ever seen
the half
moon patterns and buckshot patterning associated with inbreeding,
during
usage of a field backcrossing situation. Perhaps this could be
discussed a
lttle more here for reader understanding for the basics.
Dave wrote about saving fragements,
so that genetic information is not lost,
and I wrote about not saving the weak, but either letting them
die or
absorbing them into other colonies for strength. I can certainly
see Dave's
point on destroying weak or sickly bees as being of no use, and
we do not
aborbe sickly bees, but I most certainly do believe in combining
weak
colonies or abosorbing into other stronger colonies.
Many times 2-3 weak colonies
combined, going into the winter or early
spring, will come through strong. There is no need to find the
queens or
make a selection, of which would be best to keep. The bees themselves
will
do that. Question: Is this not a way thru absorbtion of keeping
traits that
would have been lost, if the only thing not liked about the colony
was the
size of it's force (weak) for going into off season conditions?
What
survives in the absorbtion is what is best for survival then,
Yes? Just
giving something a chance to go for it and seeing if it has the
fortitude to
go for it!
Dave said, " No, I do
not use an incubator, I prefer my virgins to emerge in
a small colony of about 1500 bees. They fly from these for mating
and then
are allowed to lay up the small nuc so that their quality can
be assessed.
Reply:
I myself like to use an incubator
in conjunction with out-of-season breeding
cycles. By using late breeding or early breeding cycles, we can
avoid many
yellower drones in our area. The virgins emerged within the incubator
can
then save precious time on a breeding program and increase it's
success
ten-fold, by allowing for sorting of queens for body conformity
and colour.
The virgin queens, can then be taken immediately to the field
and smoked
into marked colonies where yellower characteristics are, skipping
the darker
caste colonies. This way several virgin queen lines can be smoked
into a
single yard for outmating, to give a very wide genetic makeup
and secure
large broodrearing patterns for honey production.
Dave wrote: "Indescriminate
or repeated inbreeding will lead to disaster. I
believe the American practice of 'splitting'colonies increases
the chance of
inbreeding and is a major reason why so many US outfits purchase
commercially produced queens".
Reply:
Again here, I myself do not
know how splitting/dividing/making increase of
colonies increases the chance of inbreeding and could be a major
reason why
so many US outfits purchase commercially produced queens.
As far as I know, over 2/3
of the colonies in the USA are not requeened by
use of commercially bought queens. This is statistical fact and
has been for
a number of years. Splitting is not inbreeding.
I would have to see a chain of thought here to try to understand
ehy this is
thought to be so.
Perhaps in UK there is a practice
that is done, that is or leads to
inbreeding that I and others are not aware of. Perhaps Dave could
enlighten
me so I can understand and we can all talk more then and relate
back to our
own beekeeping operations.
Like I said earlier, I am enjoying
these discussions and listed above what I
consider to be a whole bee concept for seletion of colonies to
perpetuate.
Any comments on as to what we look at, in anyone particular heading
would be
welcomed, for further discussion on understanding by all.
