Q
How Dry I Am
Dear Jerry, Is there any way
to technically remove moisture from honey? What I have in mind
is to heat the honey while continuously mixing it. To what
temperature can I go without destroying the honey’s
properties? Thanks for your many responses to my questions.
Keep up the great work with the Classroom.
Sam Atsaides

A
Sam, yes there are several
ways. As you know, keeping direct heat away from honey is a
good thing as too much can darken honey and cause an increase
in HMF. HMF is what the European Union looks for to assess
honey quality. But yes, heat also makes the “air”
be able to hold more moisture. That is why Brazil is more humid
than Finland. There are several commercially available honey
moisture-removing pieces of equipment. Most do not use heating
directly, but use some type of dehumidifier to create an
environment that causes moisture to condense on a cooler device
then direct the water off. Air conditioning units do this. If
you have ever seen the water drip out of a window air
conditioner or the drain of a whole house unit, it is removing
moisture from the surrounding air and environment. Keep your
honey in such a room and either continuously stir or use some
kind of trough arrangement to expose as much surface area as
possible to this air and you can drop the moisture in it.
Dadants has a clever commercial machine that puts the honey
under vacuum to remove the moisture very quickly. The best
method is to let the bees do it for relatively free and after
extraction quickly bottle it, so it does not pick up ambient
moisture.
Q
Bees Collecting Nonpollen Materials
Hi, this has been my first
year as a beekeeper. I have been interested in bees for a long
time, but never got around to it. Let me start by saying that
my bees are stupid (tongue firmly in cheek). Sometimes I think
that the bee supplier saw me coming and said, “Hey,
let’s get rid of some of those stupid bees that
we’ve been trying to unload by giving them to this
newbee. He’ll never know the difference.”
Now a question: Two weeks
ago, we started observing the bees collecting corn dust and
pieces from where cracked corn had been put out for the
squirrels. Has anyone noticed this before? Is it good for them?
Can it (corn meal or dust) be used as a pollen supplement?
I’m thinking that this may be a factor in their
collecting of an alternative food. I initially thought that
they must not be my honey bees, but going up to the hives and
watching, I saw them returning with the lumpy stuff in their
pollen sacks and one actually carrying a chunk in its feet.
Thank you for your column, I have been enjoying it.

Karl, welcome to beekeeping.
The first year is always the easiest, too. Beekeeping books,
literature and your beekeeping buddy down the road are only 50%
correct 50% of the time. Remember this. There is tremendous
genetic diversity in the general honey bee population. That is
why honey bees have survived for millions of years and why they
may be around long after we have blown ourselves up.
Honey bees will collect
various animal feed dusts in a break in cold winter weather
when they can get to the feed trough or bird feeder. Yes, it is
thought that they are taking it back to the colony to
contribute to its nutritional needs. These probably do not
possess the protein, vitamin and fat profile of pollen, but
commercially available pollen substitutes do not either.
However, the bees are instinctively bringing back the closest
thing they can find that resembles pollen. Good thing they were
not collecting a pesticide dust! You have learned a lot this
past year. Now apply it to what you hope to have happen in
2007.
Q
Late Drones
Hello,
there are a lot of statements such as: “In the autumn the
drones are evicted” or “Drones are killed by the
workers in the autumn.” Are these statements still
correct?
On Dec. 14, 2006 the
temperature in Grahamsville, NY was unseasonably high and I saw
two unusual situations for this period of time: flying Italian
and Russian drones and winter eviction of drones. Some
scenarios are possible:
1. Autumn supersedure impulse: Bee colony
keeps drones for a new queen. During springtime an old or
defective queen will lay eggs and then the bees will replace
the queen.
2. Autumn queenless situation: Bee colony
keeps drones with a purpose to resolve this situation during
springtime. Bees will steal eggs from other hives or will
kidnap a flying queen from another colony. But these two first
scenarios do not explain the situation when bees evicted more
than 200 drones from 5 hives on December 14, December 15 and
December 18. Maybe bees resolved a queen problem during October
and November.
3. A global warming: unusual autumn
blooming of flowers (goldenrods, wild asters), due to the
warmer temperature. As a result bees from five hives (!) may
have changed their behavior.
What is your opinion about
the above described situation? Thank you in advance.
Boris Romanov
A
Mr. Romanov, your
observations and questions about drone eviction are good ones.
Thank you. I am confident that there are one or possibly even
two or three reasons for the drones you have bee seeing as of
this date right before Christmas, 2006. Drones are a biological
imperative for a colony of honey bees. Drones are the means to
keep alive that genetic component of the queen laying the
unfertilized egg to share with virgins as they venture into a
drone congregation Area (DCA). Drones are important, but
usually are first or second in removal or destruction when the
colony is under stress because they are not strategically
valuable enough to devote resources to retaining them under
certain conditions.
At this time of year we have
several things going on that tell these honey bees that it is
time to consider colony changes. One of these is the shortening
of days as fall and winter approach. Honey Bees respond to this
change in day length by producing physiologically different
workers that are designed to last through a long cold winter
for several months. Different winter drones are not produced.
Loss of consistent nectar and pollen sources is another change
for the colony as winter approaches, either from the end of the
flowering season or temperature restrictions that prohibit
foraging by the colony. The colony’s genetic variability
many times determines how aggressively they remove or cull out
those individuals that are unimportant for overwintering. The
drones will die eventually, even if not physically pulled out
as the colony clusters to stay warm. The drones are not fed and
succumb to cold temperatures as they are rotated out and
excluded from the warmer regions of the cluster. Drones are
expendable in the overwintering colony.
Now for your questions:
1. Unless there is pollen or nectar coming
in, drones are too easily raised to keep them over winter. In
the South drones are tolerated through winter as there is
generally always a little something blooming. In Florida, we
lose drones in the middle of summer, as it is so hot that this
is when we have a lack of flowers and no resources available.
Drones are dragged out and worker and drone eggs are eaten to
conserve resources.
2. Bees do not move eggs around or kidnap
queens. I think it was just time in your region for the
‘drag the drones’ impulse to engage.
3. If warming resulted in pollen and
nectar sources, then drones would be tolerated longer. Honey
Bees are highly adaptable and flexible survivors. They exist
just about from one Pole to another and everywhere in-between.
If it is warmer or colder in your area, they will respond
accordingly without forethought because their species have been
through other “global” warming and cooling periods,
as this happens regularly according to the records, regardless
of what the media says. They will be here long after we are
gone.
Q Look Into Your Crystal Ball Please
There are so many disease
problems in the beekeeping industry.
Tell me what is happening?
Robin Mountain
A
There is no one thing or one
smoking gun on what is happening to the honey bees and the
beekeeping industry. I think the problems are multiple and
interconnected. Some are genetic, some are environmental, some
are beekeeper-related and some are forced upon us from
introduced pests, predators and diseases. Anytime you mix
populations of species and their pests, predators and diseases,
those populations either partially or totally collapse. We have
those exact conditions here in the US. We have populations of
honey bees from New Zealand, Australia, Russia, AHB from South
America, Central America, Mexico, the southwest US and whatever
queens that beekeepers have brought into the country illegally
in their shirt pockets and the disease organisms, the
predators, pests and the genetics that are now mixing. Add in
miticides, antibiotics and environmental toxins and it is a
wonder that honey bees are alive at all.
With cost of production of
domestically produced wholesale honey twice as much as the
price at the dock for some foreign honeys, who in their right
mind would do this? If a person who wanted to go into the
beekeeping business full time went to the bank to get a
business loan, the banker would laugh at him. The interesting
thing is that there will always be honey bees and their
keepers. It will be those intelligent easily adaptable ones who
will fill the niches and gaps for the demand for honey bees in
agriculture, as a hobby and through commercial honey
production. And, they will make money and be able to take care
of their families. Will the industry look different 10 and 20
years down the line...I think so. What it will exactly look
like I can only guess.
Q
Mystery?
Dear Jerry, I am certain you
will have an explanation for this rather unusual phenomenon. In
front of one of my hives I see dozens of bees on the ground
unable to fly. There are also many dead. What could this be?
R.Zacios.
A
I appreciate your confidence
in my cyber ability to diagnose your “unusual
phenomenon”. But, (there is always a ‘but’
isn’t there?) trying to diagnose some of the
multi-variable problems of honey bees is tough. Here are some
of our choices: 1. Pesticides that are sprayed on blooming
crops that honey bees are foraging on. The bees get sprayed and
those that do not die in the field come back to the colony and
die, sometimes in the thousands. 2. Pesticides sprayed on a
crop of weeds on the roadside or dandelions in your yard
sometimes “poison” the pollen or nectar, which the
bees feed on and bring back to the colony. When this food is
fed on by the adults and fed to the larvae, they sometimes are
affected and die. 3. Many times varroa can vector viruses,
which cause some of the colony members to tremble outside of
the hive and then die. Severe tracheal mite infestations also
sometimes cause these symptoms. 4. If the beekeeper uses some
of the varroa control products (miticides) improperly, it will
have an effect on the colony like the above. 5. There are some
pollens and nectars, which are toxic to honey bees and will act
like a pesticide.
As you can see, we have
several major choices or combinations of choices. Which one is
correct for this time of the year is the question. My guess is
some type of pesticide exposure in the 2.5-mile foraging range
of the bees. Hopefully it won’t continue and cause more
harm to your colony. Hang in there.
Q
Pesky Wax Moths
Jerry, I always turn to
Classroom first when I get my ABJ. There is always something to learn from and
it’s interesting to know I am not alone. Through my own
negligence, a hive absconded and I did not recover the comb
before wax moths made a mess. If I pick that comb clean of
larvae, pupae and web, can I put that comb into a strong hive
and recover the comb? Should I just melt that comb down? Or, is
there something else that needs done with it? Thanks.
Don Anderson
A
It depends on how much they
have destroyed, Don. If they have absolutely eaten, webbed, and
generally made a mess of the whole thing, start over. If they
have a good start, but there is a majority of comb left,
I’d salvage the comb as you suggest by putting it in a
strong colony to protect the remaining comb and repair it. You
can put the frames in a plastic trash bag and put it in your
freezer at home to kill the larvae and give the strong colony a
head start. It’s amazing how fast wax moths and SHB can
get started, causing a problem. The beekeeper sometimes loses
and sometimes wins. Keep your eyes open!
Q
Weak Plus Strong =?
Hello Jerry, I am thinking of
combining a weak hive into a strong hive, but with some degree
of caution. The weaker hive appears to be queenless, there is
an abundance of drone cells and I could not find the queen,
suspecting a laying worker. I had introduced a new queen on 8
August, 06, as I thought that this hive was queenless, but
could not find her on a recent check, although initially
marked. What is likely to happen if a laying worker was
introduced with the rest of bees into a strong hive? I plan to
use the paper method above the queen excluder of the strong
established hive that is doing well. Appreciate your response.
Len Khan W.P.B
A
Len, go ahead with your
combination, but let me make a suggestion if you can pull it
off. Laying workers are pretending to be queens and as such are
a little bit heavier with eggs and have difficulty flying. Take
the weak hive at least 100 yards away from where it is now and
knock, dump and brush all the bees out. The normal workers can
still fly and make it back home. The laying workers generally
can’t, but sometimes still do, as Dr. Wyatt Mangum has
shown in his research. Now combine the two colonies. Generally,
the worker bees from the queen-right strong colony will either
kill the laying workers in the weak hive or inhibit their egg
laying.
Check your combined hive in a
couple weeks to make sure it is queen-right.
Q
Sticky Questions
I enjoy reading the
“Classroom” in ABJ. I have a few questions. What are the human
uses/benefits for propolis? Can you use the plastic propolis
traps in place of the inner cover to collect propolis during
the honey flow? What is the best time of the year to collect
propolis if not during the honey flow? Where do I go to find
more information on collecting/using and selling propolis? Why
don’t more beekeepers collect propolis? What is the
average amount of propolis collected from one hive during the
year? Thank you for your help.
Tony Hubbard
A
Good questions, Tony.
Propolis is the sticky tree saps, gums, and resins collected by
honey bees to seal up cracks and crevices in the hive, coat the
wooden hive surfaces and even the insides of cells before
re-use. Depending on the tree, bush, flower, leaf or plant the
“propolis” will have varying degrees of
antibacterial and antifungal properties. The most research on
its uses and benefits has been done by the Eastern Europeans.
In the old Soviet Union days it was called the poor man’s
penicillin. It can be found in specialty products like
toothpaste with propolis, mouthwashes, gargles, wound
dressings, etc.
Activity, which is
documented, varies of course with the plant source from which
it comes. Propolis can be gathered at any time of year, but is
collected most abundantly in the late summer and fall of the
year as the colony seals itself up for winter. Some races or
strains collect and use more than others. I would do a search
on the web using the word propolis, which will give you
thousands of possibilities.
Most beekeepers don’t
collect propolis, probably because it takes additional time,
labor and equipment for an unsure and often poor U.S. market.
This product could be a marketer’s dream because it is so
underexposed. However, making unjustified claims for it
healthful benefits will cause an eventual sales backlash. Stick
with the documented facts!
Just like honey, propolis
production will depend on the strength of the colony, its
genetic propensity to collect propolis (Caucasian bees love to
plug their hives with it.) and the plants that are offering it.
Take the ball and run with it Tony. The market is still wide
open.
