Olea's hive with Laura

Laura was down for Thanksgiving weekend and we took a look into Olea's hive.  The bee population looks pretty small.  There was no capped honey and only a few capped brood cells.  We didn't see the queen.  I'm pessimistic regarding this colonie's survival.  I don't intend to requeen the top bar hive, but I may change my mind down the road.

Old hive decreasing population

Over the past 1-2 weeks, I've noticed that the activity at the entrance of the old hive seems to have diminished.  It certainly is less active than at the new hive next door.  Yesterday I took a look into the old hive to see if I could spot anything amiss.
There was no honey at all in the top super, so I decided to take it off altogether.  Only two frames in the other super had honey.
In the upper brood box, there were 4-5 frames with honey, no brood. On a few frames, there were some empty cells surrounded by honey, suggesting that brood had once been there.  There was nectar in many of the empty cells.  (So they weren't really empty, were they?)
In the deep box, there was only one small patch of brood and larvae and I didn't spot the queen.
I did get the sense that the population had contracted.  Previously, there had been bees in the Vivaldi box, but there were no bees above the first super on last inspection or this one.  Also, there didn't seem to be as many bees as previously in the upper brood box.  Once again, we'll have to wait and see.

Pieces of propolis

On the bottom of two adjacent frames were leafs of propolis.  It looked like they may have formed a small dome.  I looked in the hive to see if there was anything the bees may have walled off, but I saw no foreign objects.  I took the propolis and added it to my small collection. 

Bees in jar coated with powdered sugar

Only two!

I did another sugar roll count.  This time I changed my collection technique.  I used a larger mason jar, put the powdered sugar in first and used a measuring cup to scoop the bees out of the bucket.  It was much easier, I got the full 1/2 cup and I didn't squish anyone.  This time there were only two mites- hooray!

After one week of MiteAway Quick strips

I took out the MiteAway quick strips today; they'd been in for one week.  I dumped the contents of the trays from below the screened bottom into a dish.  Most of the brown stuff is mites.

No top queen but plenty of mites

Inspected both hives today.  First the new hive.
Once again I was impressed by the number of bees in the Vivaldi box.  I didn't see the queen or any larvae or capped brood in the top box.  Honey was being made in most of the cells in the central frames, including where there had previously been brood.  I did take a good look for the queen.  I assume she's gone.
In the bottom brood box, I did see the queen.  There was only a little honey and a bit of capped brood.  I didn't see, nor look hard for, any larvae.  I collected bees for a sugar shake count by dumping them into a bucket and then scooping them up into the jar.  Results of count below.

In the old hive, I checked for honey in the supers by heft only.  It didn't feel any heavier than last time.  In the deep boxes there were about 6 frames of capped honey combined. As in the other hive, I spotted the queen and collected bees for a sugar shake count.  I also saw a bee that was deformed- it looked like she had only a rudimentary abdomen and her wings looked thickened.  I set her aside for a photo, but she wandered off while I was busy.

Then I took my two jars of bees in for the shake count. It was awful!  About 1/3 cup of bees in the old hive with 31 mites and 1/2 cup of bees in the new hive with 48 mites.  My calculations are 15.5% in the old and 16% in the new.  But with that number of mites, even if my calculations are off, I need to treat.  So later this afternoon I went back and put Mite-away quick strips into both hives.

Phorid fly

As many of you have read, there is "new" pest bothering the honey bee- the Phorid fly.  I thought I should check to see if my bees were infested.  I found a site, ZomBee Watch, which has a map of reported infested hives.  Since there was one reported in Soquel, I figured my girls must also have been parasitized.
I didn't read the tutorial on the ZomBee site before I did my set-up, but just did it a simple way.  I hung my work light, with a florescent bulb, in front of the hives on a length of pipe.  When it was dark, I turned on the light.  One hour later, I went out and found 3 bees climbing around the light.  I put them, as well as a dead be from the walk below, into the jar I use for the sugar shake test.

Today, 7 days later, here's what I saw when I looked into the jar:
Those 3 brownish ovals at the top edge of the bottom are pupae.
There was a fourth, lighter pupa on the side of the jar.
I had been looking into the jar daily and had not seen the larva.
I examined the bees carefully and was unable to find the hole through which the pupae had exited.

The pupae out of the jar

 I transferred the pupae into a plastic vial and will wait until they hatch.

I submitted a report to ZomBee but it won't be complete until I report on the flies hatching.
