The number of colonies has been reduced to 9 for this winter; just a little bit less work to do.

Rather than mixing up sugar solution I decided to give Apikel (an invert sugar solution made from maize) another try. My first attempts some years ago could have been the cause of colony loss but others haven’t reported anything similar so I decided to try again. In addition to the Apikel I did give every colony a few pounds of waste honey.

Varroa figures were much higher that I’d hoped so I decided to give an autumn treatment of Apivar miticide rather that wait until mid-winter with the oxalic acid. Better that they go into the new year varroa-free. After three weeks, the Apivar strips were removed, heavily abraded, and then replaced in a different position. Research has shown that abrading increases the efficacy of the strips in the latter half of their life.

I have started compiling my End of Season records; provenance of the queen, average colony behaviour and total honey yield. This gives me a good picture of every colony when they start to emerge in the spring.

Lecturing and classes have been very different this year and will continue to be so in 2021. To this end Steph Green and I have started filming what I would call snippets to complement the theory classes when they start in 2021. So far we’ve done cleaning and storing of supers and next week we cover the choice of smokers, their effective use and keeping them clean.

Although on the surface it looked as if all 10 hives had survived the winter, the first spring inspections revealed otherwise. Two were queenless and two had drone-laying queens. The fifth was so weak it really didn’t deserve to survive.

Result; I have lost half my stock. Only once before in over 40 years have I ever lost colonies in the winter.

What was strange was that queenless hives 5 and 6 continued to forage keenly bringing in both nectar and pollen. The latter is said to indicate a colony being queen-right. Test frames of eggs from another colony were inserted into both. Had they no source of queen pheromones they would have immediately started to draw out emergency queen cells. No such cells were developed which was a weird phenomenon. The colonies continued to dwindle as no eggs were being laid.

They had to be united with another colony but a normal unite wouldn’t work as they thought they already had a queen. Their population was used to supplement the abysmally small, but queenright hive 2. Bit by bit they were moved closer together until they could be shaken out in front of 2. First I caged the queen in hive 2 just as a precaution and shook out the smaller colony and took their hive right away. A few days later I then did the same with the larger. The result is that hive 2 now has sufficient bees to care for brood and the queen is merrily laying away. By the beginning of May they should be large enough to take a super.

The rape came on flower and the first supers have gone onto the five healthy hives. This is where the excitement starts to build and we see the distinct difference between colonies. By the last week of April, hive 3 has three supers and hive 4 is still on its first.

The month has been gloriously sunny and as I gardened each day, the air was full of the gentle hum of the girls hard at work in the greengage branches and down at ground level on the wallflowers.

Of course, continual sunshine meant that the nectar dried up and by week four they were getting a little cross. A solid day’s rain in the last week has hopefully corrected the situation.

However, only half the usual number of bees means half the usual amount of honey so they’ll have to work twice as hard. Maybe the lack of air pollution due to CV lockdown will give them extra impetus.

To those I promised bees this spring, don’t hold your breath.

Apple weekend at Audley End House was once again a terrific two days. Unfortunately the Sunday weather was appalling and by lunchtime the footfall had reached the staggering total of 150; Saturday’s total was 1500. We had an excellent team of helpers on both days and as usual the observation hive proved a great attraction.

Back in the apiary the number of hives has been united down to the usual over-wintering eight. The last three were each 5-frame nucs, one of which was the observation hived used at Audley End.

Amongst the 15 frames were several with yellow spacers, indicating old frames to be rendered, so these were removed. All the others with bees were given a spray unite. This was probably not necessary as I was uniting three colonies but I thought it best to be cautious. Colony smell must be smothered to unite two colonies but with three colonies they can’t sort out who the intruders are and peacefully accept their new foster sisters.  The spray was a very dilute sugar solution and a drop of oil of lavendre.

One barren queen was removed and the other two left to fight it out as I couldn’t choose which was the better. They are all now in hive 6 and the feeder is fitted.

  1. All hives now have an Ashforth feeder and all the feed is ready. Most of it this winter is recycled honey with just a small amount of sugar solution to help prevent crystallising.Inspections have been reduced in the last part of the season as little could be done. All I needed to do was monitor the varroa drops. This has stayed sufficiently low for treatment to wait until the mid-winter oxalic acid.

My first honey extraction was very late this year due to the absence of rape honey. The field was right on my doorstep but no nectar.

That’s three years in a row with rape within easy flying and all they’ve harvested is pollen. I went to speak with John, the farmer, to see if he’d changed his seed variety recently but “No, I’ve been using the same variety for the last three years.”; Campus. A quick search revealed that research done by Newcastle and Exeter Universities found that modern hybrid rape, Campus in particular yielded nectar little better than water. The bees know best; not worth the energy.

It’s ironic actually that said farmer gets a subsidy for sowing pollinator strips along his headlands but can then sow a distinctly pollinator-unfriendly crop in the remaining 35 acres.

On a similar note, another long-standing member of Saffron Walden Beepers was talking with a farming friend who was disappointed that he could no longer appreciate the once beautiful aroma of his field beans. This beekeeper had moved some hives onto his huge field which he reckoned should yield in the region 1,000 lbs of bean honey. He got 150 lbs. Yes, the farmer had changed to a hybrid variety.

Who is to blame? Is it the farmers or the seed merchants?

Queen mating has been a problem this year with the loss of seven queens failing to return from mating flights. This has left me on the verge of a problem but I should just have enough 2018 queens to go into 2019.

The last two weeks of July have seen a terrific mystery flow and this has helped tremendously to overcome the oil-seed-rape loss; not so good for creamed honey but it is at least a harvest.

This mystery flow finished on the 29th. On the 30th I saw intense robbing of hive 1. I removed the entrance block and replaced it with one which had only a one bee-width hole in it and leaned a large sheet of glass on the front of the hive.

By the time I had gone round all the other hives and narrowed their entrances down to winter-width (about 40mm) the intensity of the raiding had decreased noticeably. The hive inspections I had planned for that day were put on hold. Opening up a hive under these circumstances was only asking for trouble.
