|Edited from a series of emails:
>... you mention a large queen supplier
that was supplying queens with nosema, don't expect to to
say who, but were the queens carniolans from Slovenia by
No. Although that is possible, too. I
have no knowledge of that one. I was referring to a supplier
more local to North America.
> ...there was a lot of problems with
queens from Slovenia last season, many hundreds, i believe
they could well of had the same probs, definitely one's
i had were nosemic, and reports from one large importer
of queens disappearing, not building up, failing soon after
introduction suggests many were like mine.
I think this is a problem that has suddenly
appeared worldwide and taken many by surprise. I have not
treated for nosema for decades, but am now on the watch.
I'm thinking thymol may be my solution.
> ps, keep up your diary, it's both,
interesting and informative.
Keeps me on my toes.
> Pleased to hear you say that about
the thymol, don't know if you remember my over long pm on
the forum about feeding thymol in syrup,
I can't recall. I think I had to empty
my inbox there, too. You don't happen to have a copy?
have been doing this for years pre 2002,then the nosema
levels rose slowly for the past 7 years, had probs over
a year ago in spring and went back to using thymol syrup,
this spring nosema no problems at all, R.O.B Manley was
using thymol back in the 40's,
So I have been hearing. What was his purpose,
do you recall?
> Manley's main reason was to stop
syrup from fermenting ,especially when late feeding of colonies
is carried out like when they return from the heather in
autumn. don't know if you have seen this link about thymol
on Dave Cushman's site.....
That's where I saw the reference to Manley.
> i use
3 times Manley dose emulsified with lecithin to give a very
stable suspension of the thymol throughout the syrup mix,
just under 1g per gallon which is 5ml of the thymol pre
How do you make the pre-mix?
> My recipe is same quantities, but
not so much surgical spirit, this being replaced by water
to emulsify, else the oil tends to just float on top, or
a proportion of it.
- 30g thymol crystals. placed in
- add 5ml of surgical spirit/isopropyl
alc/meths any one of these works,
- place this jar in water bath of
boiling water to help dissolve.
honey jar....140ml of boiling water,
- add 1 teaspoon of lecithin granules,
- place jar in hot water bath
to keep hot and help dissolve the lecithin,
- takes about 10/15 minutes,
- strain out any undissolved lecithin
through tea strainer or such like,
- then add the dissolved thymol
to the water lecithin,
- shake well, several times.
> this you can then add at 6ml to 1
gallon of syrup, which would be 1g per gallon of thymol,
i use 5ml for nosema per gallon, or 5ml per 3 gallons to
prevent any fermentation, even if unsealed in hive by bee's.
> lecithin granules are easily obtained
from health food shops, very cheap.
helps with varroa control, apart from the 7 years of not
using thymol i have always used it in autumn syrup feed
since the late 70's,
> i currently have 240
75 nucs, did go to 300, heading that way again, and higher,
now sons can help me some. nothing on your kind of scale
though Allen, this is the uk, would not hold as many as
you used to run
That, for me, is now a distant memory.
> ps...i believe since varroa the diseases
like nosema have been well overlooked, everyone so pre-occupied
with varroa that they thought nosema had gone away, when
levels have become much worse, then of course there is ceranae.
I really do not know what to make of all
> Makes perfect sense really, thymol
is a fungicide, nosema is a fungi, so thymol is bound to
have a good effect in clearing up, or preventing nosema.
plus i believe when the bee's are fanning within the hive
to reduce the moisture content of the thymolised syrup,
the vapour has has a detrimental effect on varroa ,plus
can work in a systemic way within the bee's when the mites
feed from them, and the larvae within the cells. And the
bee's love the stuff, seems to keep them very healthy.
Do you mind if I use some of this conversation
in my diary?
> No Allen i don't mind at all,.
gave me a thymol quote today. A 25 kilo bag is $1,125.00.
2 week delivery. Irwin's source (right) looks much more reasonable.
Maybe there is a purity difference? Click and go...
brought my Ham radio walkie-talkie along and spent the afternoon playing
with batteries. There is a lot to know. I have some old
rechargeables, and was working on rehabilitating them. Although
they are a little more work, rechargeables can save a lot of money.
I'm looking at getting a Spot and it will eat batteries, too.
Add to that my GPS...
Check out the presentation at left.
Click and go...
and I went to the Sportsman's Show, and I found the Spot unit I have
been looking for, so I bought it. After activating it, I went
to Bill's for his birthday supper.
I activated the tracking feature before
driving over and back. The map at left shows the plots.
The unit sends a 'breadcrumb' every ten minutes, marking my path. I also
sent an 'OK' message which shows on the chart, too. So far this
looks promising. I got the unit for when I am sailing so people
can track my progress. The unit also provides emergency SOS capability.
updated the scale hive charts and they are presented below. Ellen
continues to send me daily readings.

The plan was to launch Bill's
tin boat on Ramsey and test out our various outboard motors.
We got off to a good start. I went to Harri's and got the
9.9 and went to Bill's. It turned out that his boat trailer
had a flat tire. We pulled it off and went to Princess Auto
and that was the afternoon.
Mom took Linda, Sid and me out for
a prime rib supper.
I've been using ham radio again.
Bill and Faye are hams, so 2m is handy for keeping in touch.

We knew this was coming.
We just did not know when.
This probably won't be too hard
on the bees. A few days confinement won't hurt too much,
especially if there are enough patties on to hold them.
They won't be foraging on the ground, but maybe they will be
able to work bushes and trees if any are yielding.
This is a most vulnerable time.
The nurse bees are old, and working to raise new replacement
bees. The young bees emerging are still not fully developed
and ready to take up the tasks.
Open brood and the emerging bees
need lots of protein and I was not seeing any pollen around
the brood before I left.
The bees are going day to day
and extracting protein from the nurse bees' bodies to feed larvae,
and the emerging bees have to make do with what they find.
It is well documented that
there is a window of opportunity for the young bees to
develop if protein is available. Additionally, if there is not enough protein for the open brood, it will be
torn out by the bees.
& I are still trying to get to the outboard motor testing.
Before we can get on the lake, we have to mount the trailer
spare tire, load the boat
onto the trailer and head for the lake.
I had lunch with Mom, Linda
and Kyla at the Cardinal, then got the valve stem fixed.
I returned to Bill's and we finally got the boat and motors
loaded and headed for Bell Park.
The motors both started well and we ran over to
Mom's across the lake for coffee. On returning, I noticed some oil seepage
from the bottom end. Back to Harri, it goes, I guess.
Today in Swalwell

Bill and I are headed out to camp this morning to check
trip to Whitefish Falls went well, and we got out to
Tepee 2300 around noon. Everything was in good
shape except that one of the docks had come undone.
It took us a half-hour to get it hooked up again and we
were back in Sudbury by 4:30. You can see how Spot
at this page. Seems to me that the page is
screwed up when I checked it just now. It says the
trip was 295 days ago and some of the track that was
there earlier is missing. The page was OK a while ago.
I'm not too sure anymore about Spot's reliability.
I had plans to do a few more things, but
found I was tired after the day outdoors and went to bed
The storm in Alberta apparently caused
power fluctuations and outages.

Honey Bee Virus
Sampling Information and Some Casual Observations Regarding
Essential Oils and Viruses
When we were speaking in Orlando, I recall
you mentioned that you had used some essential oil mix that seemed
to reduce the viruses present in your hives. I can't recall if you
mentioned the name of the supplier or could not recall at that
moment. If I remember correctly, you said he was a commercial
beekeeper and sells the product. You gave me your card and I think I
was to email you for the details.
Some of us have been discussing various
essential oils and other such compounds and would be curious to know
how to contact your supplier and to learn more about the product.
Thanks in advance.
I apologize for not getting this back to you
sooner. I have moved my lab to a new location and have had more
things added to my to-do list than I want. With all that said we are
up and running again and I am in catch-up mode.
The essential oils were used by a few
beekeepers last year and I was able to pick up an observed decrease
in the viral titers after the application of essential oils. This
year we are putting a experimental approach to verify those
observations and to give some data that shows the affects of the
essential oils on bee health and viral loads.
The contact for essential oils is:
LeFore's Farm Fresh Honey
53588 W. Crockett Rd.
Milton-Freewater, OR 97862
I have shown that monitoring the viral load
in bees is useful in monitoring bee health. By monitoring the viral
load over time ( once a month) an observable change can be seen in
viral titers (the number of virus particles), this can be linked to
other factors that affect the bees such as nutrition, mite damage,
pesticide damage, Nosema impacts, and a variety of other factors.
The reports usually have a short turnaround time and helps with the
timing of application of treatments such as the essential oils.
I would recommend a regular monitoring of
your bees to establish a baseline so that we can take notice of
adverse changes in your bees.
If I can be of further assistance let me

(attached). The magnitude of the drop is significant. From high to
next to nil. Now I have to say I had no controls and this was only
observational over 20 colonies that I had tracked for over a year.
We are conducting anexperimental program on essential oils this
Yes you have my permission to quote me on
anything I have given to you.
Please indicate that this was observational
The cost is $40 per sample. One sample per
50-75 colonies per yard is fairly representative of that yard.
I am no currently constrained. If I have too
much volume we can expand
without too much difficulty.
This was a casual test, however we were
testing nearly 100 samples monthly from the same beekeeper. The
colonies that had essential oils only were all similar to the charts
that I sent to you. The ones that had other treatments with the
essential oils as well had mixed results and the ones that had no
essential oils were more typical in the continual increase in the
viral load although not consistent, this is why we are conducting an
experimental process that will verify these results, I hope. I have
tracked these same colonies for two years and the viral load was and
is somewhat predictable in the viral load.
I believe that the samples were taken from
the top of the colonies, I am not sure of the exact location, I
would have to refer to the data set. I do know that I have been
successful in the training of the beekeepers to be consistent in
sample gathering from the same location.
I hope this is helpful

I picked up a survey from the owner of a
boat I am looking at, then met Mom for lunch at Ginga's.
Next, I went looking for a new toilet tank to replace a
cracked one at home. No luck.
I then ran out to Sudbury
Cycle & Marine. I had noticed the place
previously, away out by Coniston. I was pleasantly
surprised to find friendly, helpful staff and a good
After supper, I patched
the old tank with Marine Goop and polyurethane. It
looks a good as new.
I'm planning to go to
Spragge tomorrow to look at the boat.
turned out to be cool and rainy, so I decided tomorrow
looks better. Mom and I went to see Linda.
On the way back home, we stopped at Home Hardware to get
some toilet parts. I spent fifteen minutes
searching, stooped down digging through poor stock with
no prices on the product and no assistance.
Finally, I threw up my hands and left. We then
went to the Earth Day Market and drove home.
Mom off at home and went out to Home Depot for the parts
and Wal-Mart for a large monitor for this computer and a
few small items. I don't care what anyone says.
I love big box stores. They have wide, well-lit
and well-marked isles, good selection, good
presentation, and knowledgeable staff who are well
repairing the toilet (finally) and cleaned up.
That was my day.
this new monitor. It's a 19" wide Acer. and cost
$138. I could have gone an inch larger for $10
more, but I will be lugging this one around and the
added size could be a nuisance. The higher
resolution is also a consideration. It takes a lot
of memory and horsepower to drive extra pixels and this
computer is a midget. I have to turn off some of
the Windows 7 eye candy to get decent performance.
Set appropriately, it rocks, even with a big monitor
with Spot some more and it seems to be working now.
You can see my current plots from
this page (now extinct). The breadcrumbs expire after seven days,
so if the page is empty, that simply means that I have
not turned on Spot for a week.

interest in ordering thymol. I ordered 25
lbs from Lebermuth last year. It had to be
shipped as hazardous material separate from
the rest of my order. I would suggest
getting a shipping quote and a brokerage
quote. Together both added significant $$ to
Lebermuth an excellent firm to deal with.

doing lots of trials with various EO home

the sudden jump we see on the last chart I posted.
Actually, I see I did not post it since I knew
something was fishy since the weather was too cool
for such a gain and held off posting pending asking
Ellen who is doing the readings for me. I got
an answer and just have to review the data, but I am

goes to show how things can screw up an experiment.

Remind me next

questions to say, "What issues came up during this
study which confounded the data and made it
necessary to make extrapolations which involved
guesses or value judgments"?
off to Spragge today.
a good trip out and back. The boat was not in the
kind of condition I was hoping, but the yacht club
was interesting and I was offered a job as Dockmaster. Tempting, but somehow I doubt I
