This is the question for us beekeepers. A recent study from Beeinformed group (linked here) says that colonies would actually have higher mortality, if bees are fed with honey, compared with those fed with sugar (via sugar boards) or nothing! This is rather intriguing but perhaps because feeding honey (usually from deadout colonies) might transmit nosema, AFB, etc.

A student said I would be killing my bees “because bees wont have a chance to seal their cracks with propolis” this time of the year. Well, yesterday, I fed my bees.

In the first yard, where we had 8 colonies, 4 were alive. I moved the honey supers to those still alive — the bees were already on the top, near the inner cover anyway. They for sure will die from starvation in a month if I do not give them food. Giving them sugar board might be a better idea, but then that is much more work compared to just lifting a super from a neighboring colony.

At home yard (MSU field lab), out of 4 overwintered colonies, 2 were still alive. One was actually inside a single medium box! They of course will run out of food soon, but I was surprised that they lasted this long.

The worse case: out of 13 colonies only 3 survived. Many of these were too weak anyway and they should have been united around end of Sept. Another half died from starvation, they did not have 60 lbs of honey on top of them.

So out of 25 colonies, 9 are alive. I plan to provide them with pollen patties in 2-3 weeks and expect to make splits out of them. I will need to purchase 10 to 15 packages to make the total colonies close to 40. This year’s package price is about $105 for 2 lbs of bees.

I should have done it on Saturday, it was 38F, but there was a MBA meeting that morning, and then I worked in my office until 5 ish.  On Sunday it was supposed to be 34 when I left but by the time I finished the 2nd yard and got into my car, it said 32 and then 27 when I got home (only 10 min! Not sure why the temperature dropped that fast). Still, I believe I might have 2-3 left in the spring if I did not give them food today.  Of course I do not have a proper control group (not giving them food) and see if feeding really made a difference.

Photos taken by a cell phone (Samsung S3) and I did not adjust for exposures…Snow is a bit dark — but actually matching what I saw that day.

1. A yard in Okemos. Dead ones counting from left: 1, 2, 3, and 6.

2. This colony should be strong enough to pull through. The cluster is not all way to the top yet so it looks smaller. It was about 34 F when I checked them.

3. Another shot of the same apiary as #1. here the first 2 colonies (dead) were not shown. Counting from left, #2, 3, 5, are 6 are survivors here.

4. I had to walk about 20 min to the lab from here….too much snow for me to drive in, and I had trouble even just to open the gate due to the drifted snow near the gate.

5. A sign of nosema disease (mostly like to due to Nosema ceranae, because Nosema apis shows up only in 5% of bees, if the bees have spores). but this colony survived.  The top super was transferred from another (dead) colony.

6. This one also had nosema but it died. you can see the cluster between the 2nd and 3rd frame from the right side. The cluster was too small.

7. The view of all 13 colonies. Number 3, 12, and 13 are survivors.

可是, 古狗竟然翻成这么烂的中文。。。

这对我们来说是养蜂人的问题。从Beeinformed组(最近的一项研究在这里挂 )说,克隆实际上有较高的死亡率,如果蜜蜂喂蜂蜜,与那些用糖(白糖,通过董事会)或没有喂养相比!这是相当有趣的,但也许是因为喂食蜂蜜(通常从deadout殖民地)可能传递微孢子虫,空军基地等。


在第一个院子里,在那里我们有8个菌落,4人还活着。我搬到蜂蜜超类那些还活着 - 蜜蜂已经在上面,内盖附近的反正。他们肯定会死于饥饿一个月,如果我不给他们食物。给他们糖板可能是一个更好的主意,但就是这一比例仅为起吊从邻近的殖民地超级更多的工作。




我应该在周六做了,这是38F,但早上有一个MBA会议,然后我曾在我的办公室,直到5十岁上下。上周日就应该是34,当我离开,但被我完成了第二个院子,钻进我的车的时候,它说32,然后27,当我回到家(只有10分钟!不知道为什么气温下降得那么快) 。不过,我相信,我可能有2-3个左右的春天,如果我今天没有给他们食物。当然,我没有一个适当的对照组(不给他们食物),看看是否真的喂养做了区别。

采取手机(三星S3)的照片,我没有调整曝光......雪是有点暗 - 但实际上符合我所看到的那一天。



3.另一个镜头一样养蜂场为#1这里的前2菌落(死)的未示出。由左,计数#2 ,3,5,是6顷幸存者这里。

4.我只好从这里步行约20分钟到实验室... .too大的雪让我在开车,我遇到了麻烦,甚至只是为了打开门,由于门附近的漂流雪。
