Felix, I hope that I can
answer your questions suitably for you. 1. Having a large
populous colony that can form a good cluster and keep
themselves warm during winter, relatively free of pests,
predators and diseases and having 60+ pounds of stored honey
and several frames of bee pollen are the general criteria. If
you can meet these requirements in a 1 1/2-story colony, then
you are 90% there. It’s the 10% that you have to be
careful of in that you don’t know what it may be that can
cause the loss of a colony.
2. It depends on when the
split is made. Is it on foundation or drawn comb, how good is
the queen, how is the weather, are there lots of nectar and
pollen sources? In Iowa it can be 0 to 100 pounds.
3. Honey bees are efficient
and will always choose beeswax foundation over something that
is not. Honey bees can pull, mold, stretch and otherwise
manipulate beeswax foundation into the cell shapes they need
and require. Then, they do not have to produce as much beeswax
and they save energy. Plastic foundation that is not coated
with beeswax requires honey bees to make beeswax and this is
resource-intensive.
4. There is no pure breed out
there. Picking something with hygienic qualities and crossing
your fingers on the other traits is a good place to start.
5. Just restrict the entrance
down to about an inch and seal up any other openings when you
install your package at dusk and everything should be okay if
you haven’t allowed the colony to be robbed recently.
Move the colony into some secure area for a few days before
installing the package if you need to.
6. Natural pollen is more
nutritionally complete than a pollen substitute. However, if
natural pollen is not available, then a pollen substitute can
help colonies continue to grow until natural pollen is again
available.
Q
You’re Joking
Right?
Hi, Jerry: I’m planning
on traveling to Europe (Lithuania) this summer and I’m
also planning to bring several queens with me. How should I
handle this so the queens will not die? Thank you for any help
on this.
Charles
A
Charles, your email greatly
concerns me! You need to check with the Lithuanian Department
of Agriculture. I am sure there are numerous forms, permits and
requirements for bringing any kind of living creature into
their country. Beekeepers traveling with queens in their
pockets is how we received some of our most notorious
‘gifts’—namely, varroa and possibly other
beekeeping pests as well, such as the recently discovered Nosema ceranae.
Lithuania probably has queens that are great for them and we
should keep ours to ourselves. Go, but only give and receive
knowledge, not queens!
Q Colony Collapse Disorder (CCD) Question from Germany
Dear Mr. Hayes, I am a
science journalist in Cologne, Germany, and I’m working
on a television report about the mystery ailment that strikes
honey bees in the USA, respectively, the phenomenon called
Colony Collapse Disorder (CCD).
A lot of reports have been
published during the past few weeks in Germany. There were
headlines to read like “AIDS in the beeyard” or
“USA loses nearly 80 percent of the honey bee
population”. This sounds dramatic or hysterical? In
Germany it seems that the topic disappeared from sight as fast
as it came up. I haven’t found any article for one week.
So, this is for me the moment
to ask for the state of affairs with regard to CCD. Was it just
a momentary hysteria or is there really a completely new
ailment that strikes honey bees? Are the data (70-80% of honey
bees vanished in parts of the USA) correct? Some scientists in
Germany think that Varroa
destructor is the main reason.
Was there ever a similar case in the USA? Does the decrease of
honey bees correlate to increasing monoculture or genetic
engineering? In Germany beekeepers report that it got much
harder in the past years to keep the bees as they have become
more vulnerable to pathogens. Is this similar in the USA? It
would be great if you could take some time to answer these
questions.
With kind regards, best wishes
Dirk Gilson

I’ll try to answer your
questions if I can:
1. It appears that we in the
US are on course to lose 600,000 to 800,000 colonies out of a
total 2.4 million.
2. Hysteria has certainly
preceded science, but this is human nature when your business
world is collapsing around you.
3. A malady called
“Disappearing Disease” is noted in the literature
appearing several times since the late 1800s. What we are
calling CCD seems to be somewhat different in that the colonies
that dwindle to nothing have immune systems which have been
compromised, allowing normally occurring organisms to flourish,
fungus especially. And, the colonies that are now devoid of
honey bees are not being taken over or used for reproduction by
the small hive beetle or wax moth immediately. These predators
in the tropical/sub-tropical climate of my State of Florida are
always present and take over weak colonies quickly. In CCD
colonies, they do not take over until 3-4 weeks after the
colony collapses. It is as though the colony has to ventilate
or air out before they move in, and then it is tentatively. If
one takes the dead (now empty) boxes with frames and comb and
places them on good strong colonies, those colonies die in a
few weeks. I think CCD is different from historical reports of
disappearing disease. An analogy may be if you cough, is it
because of a cold or the flu or is it TB or AIDS or an allergy
to pollen or cancer? The outward symptoms may be similar, the
cough, but the cause can be quite different.
4. Causes: Varroa can be a
problem and it does compromise honey bee immune systems. But,
we have Varroa control products and they are used to control
varroa to low levels. Beekeepers with CCD certainly had varroa,
but in low numbers. Miticides: Beekeepers put miticides in
their colonies to control varroa. We are trying to basically
kill a bug on a bug and these chemicals cannot be good in the
long term in a bee hive.
Environmental toxins: Honey
bees can forage efficiently in a 2-21/2 mile radius of their
colony. There are a lot of “pollutants” that they
are exposed to and can pick up and bring back to the colony.
Agricultural Toxins: GMO
crops and the toxins expressed in nectar and pollen from them
can be collected and the bees feed on them over time.
Pesticides such as the neo-nicotinoids like imidacloprid that
are used systemically can be translocated to the nectar and
collected in sublethal doses and used over time.
Genetics: We have a shallow
genetic pool. Is this expressing itself in specific weakness?
Tracheal Mites: Certainly a
stress
Small Hive Beetle: Another
stress
Antibiotics: Used too much to
control bacterial diseases, these can stress the bees by
eliminating gut flora and fauna that digest food. Bacteria that
are added to pollen to start the fermentation process to make
bee bread, the bees’ only usable food, is not as easily
available when bees are fed antibiotics.
Nutrition; See above. And,
honey bees may be fed substitute diets of nutritionally
incomplete materials, which affect honey bee longevity.
Moving: Now load honey bees
on a truck and ship them 3,000 miles.
New Pathogens or common
pathogens that have now become more pathogenic. Beeswax is a
chemical sponge. It can store all chemicals that the bees bring
in or are exposed to and serves as a reservoir of toxins that
the colony is exposed to 24/7/365.
There may be other things as
well. I am not sure what honey bee stress is but all these
things together certainly look like stress to me. If you and I
were stressed by chemicals, poor diet, antibiotic therapy,
parasites, travel and our house was a reservoir of pollutants I
can guarantee you that we would get sick.
Are honey bees a very small
but significant environmental sentinel that is trying to tell
us something about them or the environment they live in? Should
we be paying more attention? If the poultry or cattle industry
experienced 30%-40%-50% or more losses, we would have people
stumbling over themselves to find out why and fix it. The honey
bee industry has always been the neglected stepsister of
agriculture and it continues. At some point, it may be too late
unless we do not care about where or how our food is produced.
Then, it is a moot issue.
Q
California Questions
Jerry, just got my April ABJ, and, as always,
the first thing I turned to was “The Classroom”.
Liked your comments on infant botulism and loved your reply to
HO (CA) on imidacloprids.
Now, after an introductory
like that, don’t you always hunker down for the
inevitable “but” or “however” (like you
often see in book reviews)? Well, here it comes: But I have to
disagree with your statement
(p. 297) that “Strong, robust, vital, active honey bee colonies are rarely found in commercial beekeepers’ operations.” I can show you thousands of strong robust colonies in California citrus groves at this time. The best were strong during winter almond pollination, certainly not as strong as they are now, but plenty strong for winter bees. Maybe, if I came to Florida, I’d change my mind.
Certainly, overall colony strength
is not nearly what it was pre-mite, and probably never will be.
The key (in my opinion) is on p. 308 of the current ABJ: “We know
that when Varroa mites feed on EHBs, it shuts down the
bee’s immune system.” Our bees have AIDS and
probably always will.
I had the privilege of
spending some time with Marla Spivak in Berkeley earlier this
week. Marla told me something I wasn’t aware of: That the
preliminary results from the bee genome research indicate that
honey bees have only 3 or so “immunity genes” (not
her words, but the way I interpreted them), far less than other
“animals”. (Marla feels that the
anti-bacterial-viral properties in propolis have compensated to
a certain extent for this impaired immunity defense).
Beekeepers who have gone to
great lengths to keep their bees “healthy” have
less CCD than others. I agree with Dick Marron’s comment
(p. 300): “Anyone who thinks this is due to sloppy
beekeeping or not keeping on top of the mites, leave the room
now.” But, I’d add that beekeepers, who take
extraordinary measures to keep their bees healthy, have
stronger colonies than those who don’t.
The “Einstein
quote” ended your CCD reprise (p. 297). This quote has
been ubiquitous recently. Singeli Agnew, a grad student in
Berkeley is doing a documentary film on honey bees (should be a
good one; out in June so she says). Both Marla and I talked
with Singeli. Her thesis advisor is the renowned Michael Pollan
(author of Botany of Desire and the recent Omnivore’s
Dilemma) who is a visiting
journalism professor at Berkeley. Pollan advised Singeli to
source the quote and I agree 100%. If honey bees are essential
to human society, how did the Indians survive before the
Europeans invaded N. America? I greatly admire Pollan’s
writing skills—he’s a better writer than I’ll
ever hope to be—but he makes me cringe with some of his
conclusions, which are a bit off the wall (as are many in the
organic “movement”). His writing is so seductive
though, that one rarely steps back and says, “Now wait a
minute here.” He does make many good and valid points,
but mixes in a lot of questionable stuff with it.
Joe T
A
Joe, thank you for your
comments and your insights. I guess what I meant from my
statement is, just as you alluded to, there is sometimes
tremendous inconsistency in colony “health” and
vigor. Sometimes they are strong, sometimes they aren’t,
and many times everything in between. And, this variability can
occur throughout the season. Varroa is a big culprit and
everything that is used to control it. Add in environmental
toxins, agricultural toxins, poor incomplete supplemental
nutrition, etc., and honey bees may be the canary in the coal
mine.
Marla is absolutely right
that the honey bee’s immune system, genetically, is
pretty shallow. Not only propolis, but also beeswax is an
important component. Beeswax in this highly developed communal
insect system is a chemical sponge. A poor analogy would be the
liver in humans. But, when this sponge fills up, then what? I
think we are filling the beeswax comb up pretty fast and it
can’t handle the load. So, the colony is exposed to stuff
24/7/365 in synergistic ways and it is not good.
The Native Americans did not
have 500 acres of European foods that need honey bees as
pollinators. They had small acreages of native
insect-pollinated and wind-pollinated foods and native
pollinators like squash bees, bumble bees, solitary bees in a
vast unspoiled (by chemicals) environment with lots of nesting
sites to pollinate. Pollan is a good writer and thinker and,
yes, he is out there a bit. Sometimes we need these people who
operate on the edge to help us see in different ways.
Isn’t it interesting,
fun and a little scary to be able, at our ages, to look behind
and then extrapolate to the future. We can see what is coming,
but nobody listens to us because it is too uncomfortable.
Fascinating.
