Back on February 19th the blog posted an article on significant colony deaths during the almond bloom. This next article indicates the cause may have been found. A mixture of fundicide and insecticide were sprayed when the bees were present. Although OK when applied singly, the combination is lethal. Follow the link.

NEONICS NOT A SIGNIFICANT FACTOR IN BEE LOSSES
Follow the link to an interesting article. Sorry but the conclusion is mites and viruses are the primary causes of bee losses; not neonictinoids. Think about your mite control program now!

ECWBA MEMBERSHIP BENEFIT
The club has purchased 20 pounds of oxalic acid powder in bulk and re-packaged it for members. This reduces the cost of oxalic acid from roughly $10 per pound to $3 per pound. The re-packaged oxalic acid will be distributed at the March club meeting only. (Please remember the March club meeting has been rescheduled from March 16th to March 23rd). There will be one (1) pound and 1/2 pound containers available at $3 and $1.50 respectively.
To calibrate your purchase, remember that one pound equals 454 grams. It requires 2 grams of oxalic acid to vaporize a hive of two 10 frame deeps. Most hobbyists will not use more than a pound throughout the year. Those beekeepers with one to two hives can get by with 1/2 pound for the year.
If you would like to reserve a container you can email Fred at "fredransome@aol.com". Specify the size of container you desire. If you do not show at the meeting your reservation becomes void and the container will be available for other club members.
If the club receives reservations far in excess of the 20 pounds available the club will contemplate an additional bulk purchase.

WILL MUSHROOMS SAVE THE BEES?? submitted by beekeeper Jon
Here is a link to a YouTube video, which states the mycelium in mushrooms is beneficial for bees. ECWBA has no evidence yet that the claims are valid.

ANOTHER BAD WINTER???submitted by Beekeeper Gerard
It appears that some of the big commercial beekeepers are having a bad winter as far as hive survival is concerned. Follow the link below to the article. Will this affect package supply or prices?

EATING HONEY IN PERU--submitted by Grandpa Jack
Grandpa Jack received this photo from friends visiting Peru. The honey in the restaurant was fresh and directly from the comb.
Editor's note: Unlike our extracted and filtered honey this honey is being served with the wax particles still in the honey.

BETTER WEATHER OR MITE CONTROL??? by beekeeper Fred
On this cold day with snow flurries I spent a little time
thinking about the greatly improved hive survival experienced by beekeepers
Fred, Gerard and Jon this winter. Was it our concentration on mite control last
summer and fall or some other factor such as more benign weather? We had been preaching the necessity and benefits
of good mite control all last year. Do we
have enough evidence to draw a conclusion that it was the mite control and not
the weather? So, I
took a little time to review my notes from this winter and last winter.
This winter was milder than last winter through the end of December. Last year the below zero nights began in
December, while this year they held off to January. By my count, last winter there were 15
below zero nights. This winter there have been 11 below zero nights so
far. That could make one think last winter was worse than this winter.
But last winter the
coldest night was -14F, while this winter we hit -30F. From this standpoint this winter was the
worse of the two. Just looking at the
below zero nights last winter had a total of 106 degrees below zero over the 15
days or a -7F average. This year a total of 121 degrees below zero over
11 days or -11F average. Again, this winter was again worse.
Last winter had seven
below zero nights in a row. This year had only five below zero nights in
a row. Repeated cold nights and days inhibit the cluster from moving to
food and can result in starvation. Last
winter was worse from this perspective.
Last winter the cold
nights started earlier (December) in the winter, when the bee clusters should have
been larger and better able to handle the cold. From this perspective this
winter was worse because by January natural attrition within each hive would
result in smaller clusters less able to withstand cold.
From my viewpoint the
two winters were about the same with a slight edge to this winter being
worse. Also our survival rates are
significantly higher this winter.
Therefore, I feel the
better mite control each of us practiced is the major factor in our better
survival to date. It is also interesting that hives with either local or
package queens are having the same excellent survival.
February is the time for
the hives to start brood rearing. This
makes a big demand on food resources within the hive. More food is needed because there is now brood
to feed and also because the bees increase the brood nest temperature to 92F to ensure
survival of the brood. Late winter starvation
may occur if the hive runs short of food for these two functions. Now good beekeepers need
to follow through and make a late February and mid-March feedings. Both
sugar and pollen or a pollen substitute are recommended. Don’t be lazy and lose your hive at this late
point. Get out there and either verify
there is plenty of honey or by adding emergency feed.
We can discuss this at
our February 16th club meeting:
9:30AM at the Caestecker Public Library in Green Lake. See you there.

BEES CAN ADD AND SUBTRACT???-REV. 1
Here's a wild story. Now if only they can count varroa.

LOCAL QUEENS VERSUS ????
There are frequently discussions about local versus imported queens. The following article seems to say that local versus imported queens have about the same winter survival. It also states that colony strength, hive weight, and varroa control are far more important factors in winter survival.

END OF JANUARY APIARY REPORTS FROM THE THREE AMIGOS by beekeeper Fred
Well the polar express has come and gone; hopefully there
will be no recurrences for the remainder of the winter. By my count we have now had 9 below zero F
nights this winter; the worst being -30F.
On the positive side the amount
of daylight has increased more than an hour since the winter solstice back in
December.
They say healthy, well fed, bees can survive extreme low
temperatures. I’ve worked hard at both
aspects with a strong varroa control program, fall feeding and adding emergency
food stores to all hives. Just prior to
those two nights of -30F temperatures I went out and surveyed my hives. At that point I was still holding at the 97%
survival level. But it was with more than
a little trepidation that I went out today, February 1st, to check
on my hives again. We can
say that these extremely cold temperatures are acting to biologically winnow
the weak from the strong. I guess the survivors can be truly called
survivor stock.
The three amigos shared their varroa control programs from
last summer during our December club meeting.
All three programs were shown to be effective based on Randy Oliver’s
varroa model. The results we are seeing
this winter seem to agree.
So here are my results.
Over the past 9 below zero nights I lost NO hives. To date 97% of my
hives are still surviving! So far, I am
a happy beekeeper. At this time last
year my survival was only 60%. Even all
12 nucs are still alive, which totally surprised me. Beekeeper Gerard reported yesterday that all
of his home hives are still alive. He
also reported -36F. Wow! Beekeeper Jon has reported that 94% of his
home hives are alive. So, the increased
focus on mite control by all of us appears to be improving winter survival and also confirms the prediction of Randy Oliver’s varroa model.
After a brief early
February thaw, I see the weather forecast has another short bout of below zero
nights about a week from now, but this time for only three days and only down
to -4F. There are still 2 months of winter to go, so
tomorrow we will all be checking the emergency food supply in our hives.
