Monday October 10th 2016
We had coffee and pastries in the club room, got ready to leave, and pulled out around 1100, headed back towards Sidney.
We walked the strip, then returned to the boast and set sail for Butchart Gardens, figuring there was plenty of daylight left for the trip.
We arrived well before sunset, caught a mooring ball, tied a stern line to the shore, had supper, then turned in early.

We returned to the boat and watched Men in Black II.
Wednesday October 12th 2016
We found there was very little wind as we left the bay in the morning, but we had enough to fly the spinnaker and make 2.5 knots in the general direction of Sidney.
We had decided to return early since we both fly out at 9:25 tomorrow and are expecting Peter to pick us up at the marina at 0800. I always need three hours to put things away and pack and, besides, a gale is forecast for this evening and the dock is the safest and most worry-free place to be.
We stopped at Van Isle, fuelled up, motored to Port Sidney Marina and found our spot was occupied by a boat hogging two spots.
I rafted to the interloper and we shuffled the boats around until Cassiopeia was in her right place. We then closed the enclosure, filled with water and went uptown for supper. We went to the Beacon Restaurant where I had eaten the best Caesar salad ever not many weeks ago. I ordered the salad and this time it was about the worst Caesar salad I have ever eaten. The dressing was wrong and the lettuce was old and limp.
Even though we are on the inside dock and as sheltered as any boat in the marina, Cassiopeia rocked and rolled all night in the gale. Halyards were slapping in the wind and at one point I got up to adjust our spinnaker halyard, but to no avail.
In the morning the wind had died, but it was still raining. Peter was at the marina at the appointed time and soon we were at the airport.
Don and I were on the same plane, but sitting separately. he is an nervous flier and likes to be over the wing. I like action and the view from a window seat with a clear view of the ground.
We landed in Calgary, said farewells and he flew on the YYZ. I retrieved my van and drove home, shopping for groceries along the way.
I felt like crap all day and wondered if I am having another heart attack. I considered going to the hospital to be checked out but decided I'd rather take a fairly remote chance on dying than go through all the bother of being checked out.
At any rate, I did not die. Not yet anyhow.
Mid-morning, I made a vegetable stew to last me a few days and caught up on deskwork.
After supper, I watched three episodes of The Good Wife before bed. Netflix released another season a while back and I have just now gotten around to watching. I like all the characters and the interplay is interesting. Nobody is clearly evil, and they all are just doing their best, even if it leads to misunderstandings and conflict.
I started off by thawing some hamburger, but scorched it a bit. I figured it was OK, so proceeded, but when the dish was finished it wasn't very good, but it is what it is and that is what I have, so I took it along.
The party was well-attended and went until at least nine, when I left. In the meantime, I had a chance to talk to people I had not seen for a while and enjoy some pretty good music.
Today is sunny, but I am still feeling poorly. My weight is up and it is time to get it back down again.
I spent the morning at the desk,. then drove over to Ruth's to get Zip and returned home.
I wrote earlier about Apivar and how it simply does not do the job any longer. I offered a chart showing how even a small loss of efficacy will result in the need for increasing frequency of treatment or employing additional measures repeated (below).
I cannot emphasize too strongly how important that understanding this subtle concept can be for a beekeeper. A small loss in treatment impact means that the varroa populations may increase over time, rather than remaining under control.
This is illustration just demonstrates an estimated average over all hives in a group. In the real world, the efficacy in some hives will be higher and some lower than average, by definition. If low efficacy in one treatment in one particular hive is due to improper placement of the strips, chance is that the next treatment will be more successful, but the populations may be on the upswing compared to other hives nearby due to the one poor treatment, especially if the treatments are already marginal in their ability to reduce populations below an equilibrium.
Increasing frequency of treatments or increasing dosage may serve to maintain control, but costs mount quickly and the risk of failure rises over time.
While I was away last week, my friends forwarded me some information that Medhat shared regarding his recent Apivar tests (right). My understanding is that these are results of the Pettis Test, a quick test to see if varroa is resistant or not. Be sure to read the document carefully before jumping to conclusions.
Previously, we heard that Apivar was still achieving kills of over 90% in Pettis test, but as always the devil is in the details. We did not hear that in the same series of tests, Apivar scored as low as 60% kill or that one result was discarded.
Of course there are many explanations and the 60% Apivar result could be an outlier, but if this is your hive, you are in deep dodo. Besides, in another sample Apivar killed only 75% making the 60% seem less an outlier. Start worrying now.
Granted, Apistan (not Apivar) did a bit worse with one test which was clearly an outlier (due to its distance from the average) at 14%, but at 59% overall kill, compared to Apistan at 87% kill, Apivar does not look all that much better, especially considering that Apivar had the one reading as low as 60% that did not appear to be an outlier.
What can we do? We can keep doing the same thing only stronger and more often or we can look for another solution, and hopefully one that will not fail as quickly as Apistan and Apivar did. With Apivar costs approaching $12/hive twice a year, oxalic is looking very good.
I am going to risk publishing this tonight and take a chance on embarrassment for going off half-cocked seeing as I think it is important.
I'm sure I'll have a better perspective in the AM and maybe some comments.
I'm off to watch more of The Good Wife.
I did, then wrote this for the Calgary group:
There are many who dare not kill
themselves for fear of what the neighbors will say.
I slept in, then got up and worked on the Thanksgiving Rendezvous report and the plans for next year. That took pretty well all day.
I also worked on some articles about oxalic. See yesterday's post.
The actual tragedies of life bear no relation to
one's preconceived ideas.
It looks like another dull day coming up. My weight is pretty well unchanged.
We have some better weather coming soon, though if we can believe the forecasts.

Now that strip failures are blamed on operator error and wide variability in Apivar and Apistan efficacy has been revealed, the advantages over OA disappear.
Moreover, when cost, residues and operator safety (the Canadian Apivar label limits the number of strips an operator can handle in one day) are considered, oxalic acid emerges as a logical choice. (2013 Canadian label shown at right)

It's a very good presentation, but, of course, I have some differences of opinion on minor points. But I do agree with him on most.
In the video, drizzle starts at 22 minutes, vapourization at 30 minutes. Treating package bees starts at 33. Research at 35.

The weather is trending warmer. This morning, I weigh 220.4 and feel more like myself.
That feeling of well-being did not last, and I began feeling poorly again. I ignored it and worked on desk projects until after lunch , when I gave up and decided that I had better go to the hospital and get checked out in case something bad is happening.
Last time, I was gone a week. My friends took care of the dog and van and Jean picked me up from the hospital, but this time I have to guess what to expect. I decided to put things away, shovel ashes and take a chance on taking the dog along since the weather is quite mild and she is happy to sit for hours in the van. If they whisk me away to Red Deer, I'll call Ruth to come for her.
I drove to the Three Hills hospital emergency and checked in, mentioning that I was wondering if I was having another heart attack. There is no waiting if you say anything about heart. In minutes, I was on my back, shirt off, and covered with electrodes. Soon I was x-rayed from three sides, back on my cot, and staff came by to take a blood sample.
After a while a doctor came by and told me my troponin, an indicator of heart damage, measured a normal 0.02, apparently indicating no issues. Moreover my ECG was normal and a slight irregularity that appeared after my incident last year had disappeared. Seems I have a flu or something and not obvious heart problems.
I was released a few hours later, bought a CO detector at the hardware store since I had been wondering if my furnace has been gassing me, bought some fruit and drove home in time for supper.
I am feeling better. I ate roast chicken, strawberries and green grapes for supper, watched some Netflix and went to bed early, at 2100 hours.
