How a Good, Reliable supply of
Package Bees can Reduce Chemical Use in Canada
Just when I think I've remembered all the salient details, I remember
one more thing. One of the big concerns in Canadian beekeeping is
that chemical use for mite control in beehives will result in detectible
residues that make the honey unmarketable. Beekeepers, desperate to
keep their bees alive because of the uncertain and limited supply -- and
high cost -- of replacement bees are forced to use dangerous chemicals in
their hives more than they would if good replacement bees were less
difficult to obtain. In Alberta, even beekeepers who are still
getting good control with a moderate application of Apistan are being
strongly encouraged to use Coumaphos, and many who have no need to are
doing so.
Wake up people! Coumaphos is a chemical
that safety regulators in both Canada and the USA are trying to
withdraw completely from the market ASAP, due to its noxiousness.
It has no place in a beehive that is producing honey, and apparently no
place in a beehive that is used to produce queens.
What are we doing? At the very least, we're making our
beeswax unsaleable and committing to replacing all our combs on a five
year rotation! I'm told Horace Bell melted his entire outfit --
35,000 hives -- and started over with fresh wax after the chemicals
caught up with him. That is easier to do in Florida than it is in
Canada. Drawn comb is a prairie beekeeper's best asset, and we
are fouling it with a poison.
Frankly one of the many considerations that caused me to sell
when I did is the prospect of having to use coumaphos. A few
years ago, we did not know what we know now, and it looked inevitable.
I could see a lot of comb replacement would become necessary within a
few years, if we were forced to use coumaphos, and that the value of
our wax would be further degraded.
I think, however -- now that we have had a chance to consider
alternatives like oxalic acid and now that varroa-resistant bees are a
reality -- that , non-emergency use of coumaphos will prove to have
been unnecessary, and a big mistake for many Alberta beekeepers.
IMO, those using coumaphos today, up here in the north where winter and
spring bee survival is tough, will soon be paying the price in terms of
poorer winter survival and other vague problems. We're going to
need a lot more packages to keep our numbers up.
Other perfectly good alternatives have been ignored in the rush
to buy one more expensive and dangerous commercial pesticide. In Canada
and in the USA, for whatever reason, we have done the damage.
Alternate treatments have not been followed up, perfected and approved.
Many beekeepers who have never had a problem with Apistan have rushed
to Checkmite+™. I can understand Checkmite+'s emergency
application where resistant mites have been proven to exist, but
I cannot understand using Checkmite+ until absolutely necessary or
continuing its use after emergency control is achieved..
I also cannot understand why Canadians have failed to
develop and approve known safe, cheap, effective treatment treatments
that likely will never encounter resistance or foul our honey and wax
-- like oxalic acid -- but continue to promote using a noxious,
dangerous chemical like coumaphos.
The amount of money that has been spent -- in Alberta alone --
using Apistan™ and Checkmite+, compared to the cost of using oxalic
acid, would have paid for the research and approval of oxalic many
times over.
Go figure.
Anyhow... back to the main subject... How a better supply
of package bees could reduce chemical use in honey producing hives by
50% or more...
We Can Cut Chemical Use in Half!
-
Pre-treated package bees: Package
producers in California with sufficient business devote their hives
strictly to bee production. They never produce honey, just
bees. Any honey gathered is used in producing more bees. The
income from queens and bees sustains these beekeepers. Because
they never produce honey, they can treat for mites at any time of year
and keep levels very low. Bees shaken from their hives have very
low mite loads.
-
Easy, reliable, low-chemical dose
treatments possible: Nonetheless, if a Canadian beekeeper feels that
treatment is desirable on arrival, packages are very cheap and easy to
treat, with a minimum of chemical. Because package bees have no
brood for several days after introduction in Canada, a yard of newly
installed packages can be given a very brief treatment, rather than the
42 day treatment necessary for wintered hives. Because the
quantity of bees in each hive has been measured (2 lbs), and all hives
are at exactly the same stage of development, treatments can be measured
and applied very accurately.
-
Reduce the use of chemicals in the hive
by more than half: Usually no treatment is needed on packages the
first year, so one whole treatment is saved in Canadian hives -- the
bees were treated in the states before shipment. perhaps drop tests show
they need treatment the second year. By then -- using an industry
average loss figure for attrition over one year -- one third of the
original colonies die before the spring treatment, so only 2/3rds, of
the originals, if any, need treatment. If they can wait until
fall, and additional 10% has dropped off, and little more than half the
original colonies purchased need chemicals, and only after a year and a
half!
The use of chemicals in the hive is
reduced by more than half, and up to three quarters! In operations
running package bees and selling or otherwise eliminating the bees in
fall, possibly NO chemicals might be required, especially if brood
chambers are irradiated periodically.
-
Wider use of radiation to sterilize
brood combs: When forced to winter bees, beekeepers do not get a
chance to examine the frames in their brood chambers the way they do
when using package bees as part or all of their replacement supply.
In most overwintering schemes, bees occupy as many hives as possible,
year round.
In a combined wintering/package bee
operation, hive bodies can be removed from service in a scheduled
fashion and examined carefully and/or put through radiation facilities.
Wider use of radiation to sterilize brood combs could reduce OTC and
Tylosin™ use to almost nil, according to reports from those who have
experimented with electron-beam radiation.
-
Mite resistant bees:
Additionally, when imports of US package bees and queens resume, it will
be possible to obtain US-developed mite resistant bees in
mass quantities and upgrade the bee population in Canada to require less
chemical use than current unselected stock.

Listen up CFIA!
You are Canada's food watchdog, but your current policy is
contributing to the need to use chemicals in beehives, with
subsequent risks of food contamination.
Ironically, that
same ban is preventing easy and inexpensive importation of proven
biological solutions to our mite problems from the USA!
A good supply of pre-treated package bees from
California -- whether made up of varroa resistant stock, or not
-- can contribute greatly to better overall bee health in Canada,
improved management practices and significantly lower chemical
use, as well as contributing to improved viability for the
economically important Western Canadian bee industry.
What better way to
reduce residues and potential residues in our food than reduce or
eliminate the need for chemical use in hives?
Please do not even consider renewing the border closure
prohibition order when it comes up for renewal. To do so
would be to work directly against your own aims. |
