Hello Deknow & All,
The experiment ran by the USDA-ARS is important to most because of the size
of the experiment (400 hives) and the complete experiment has been over
seen by Jeff Pettis (head of Beltsville Bee Lab).
Around the world many beekeepers are watching with interest.
The information I received by phone from Australia last night was from an
Australian commercial beekeeper which spoke at great length with Denis
Anderson about his week researching, speaking with Hackenberg and the USDA-
ARS team.
For those on the list which may not know who Denis Anderson is ( hard to
believe) I will say Denis has shocked beekeeping researchers around the
beekeeping world with his discoveries about varroa and bees. Denis gave us
the term varroa destructor.
We in the U.S. are very lucky to get a researcher of Denis Anderson's
caliber to take a look and give his opinion!
Many of us are looking into the current problems but testing is not
complete. Our recent testing of taking a hive going backwards and putting
on new comb did not change the scenario ( as using radiation on the
Hackenberg eguipment has done).
So now some CCD effected beekeepers are doing queen replacement to see if
the queen is effected in some way and a queen change will change the
scenario.
work in progress.
>" shipping bees which are not strong and healthy"
I think Deknow misses the point but only because he does not perhaps
understand the way hives are moved in fall into Texas & California. There
are two methods.
1. All hives which are queenright and seem healthy are moved.This method
has an element of luck needed.
2. Only the strongest and the rest are depopulated. Works most of the time
but failed last fall with the loads of bees of Lance Sundberg which really
got my attention. Hives gone though ( Montana) and full of bees and two
weeks later ( California) only a few bees and a box full of brood and larva,
Since the "gold rush" to almonds many commercial beekeepers have moved to
using number 1 ( risky but with record almond pollination prices some feel
worth the risk). Then trying to rebuild or combine in California. Hives are
being trucked which would not have been a decade ago. Renting into almonds
is the big reason in my opinion.
As example Richard Adee used to only keep 25% of his hives (BC article from
90's) and depopulate the rest as he needed the equipment to use again. Many
of his hives were depopulated by Bell Honey in Florida and then the empty
equipment sent to the operation in Mississippi( I was involved in this
part). In those days after the honey flow in the Dakota's was over and *if*
fifty percent were dead it was not cause for concern and only meant the
deadouts were sent to Mississippi instead of Florida to be depopulated.
Actually saved on trucking and cost in Florida of depopulation. The
beekeeper in Florida at the time employed a much larger work force than the
Adee operation ( has actually been larger at various times in beekeeping
history) and was set up for depopulating the hives in a huge building
setting. Said beekeeper is retired now ( rumors say silent partner in
certain beekeeping operations ) and the plan does not really fit now since
the Adee's are big into almond pollination and as I understand go now
directly to California from the Dakota's in fall.
The point I make is one my long time friend Jerry B. has trouble with. 50%
losses seem ok with some beekeepers he seems not to understand. Unlike the
hobby beekeeper (same actually give queens names) the commercial beekeeper
decides on the number of hives he will run. As example say a 1000 hives and
he requeens every year. So if he wants to requeen all he takes one strong
hive and turn into four in spring he needs to depopulate 75% (750 hives
using the above example) to have the equipment he needs in spring. He keeps
the absolute best 250 and sends to the splitting area which in the case of
the Adee's was Mississippi and for us is Texas. The commercial migratory
beekeeper now has his 1000 hives back with new queens.
A young queen pays instead of costs!
Understanding the methods of the large beekeeping outfits is hard to
understand unless you have been directly involved such as i have for many
years. Not always do I have the time for a long explanation but
understanding the methods migratory beekeepers use I think helps in
understanding the problems they face.
Beekeeping was so easy in the fifties and sixties! Complicated today!
Still trying to retire after nine years!
