There has been
a tremendous surge of interest in Queen Rearing and in questions related
to mating these queens, both to me privately and on The Bee Works Forum.
A great many of the questions deal with mating hives for the virgin
queens being produced, creating serious problems for those involved
due to the lack of information available.
This article will deal with our methods of setting up Mini Mating Hives
and an explanation of some of the problems we discovered over the years.
Mini Mating hives are ideal for the sole purpose of mating queens. They're
small, light, only need a handful of bees, are easily portable and when
charged with bees can be self sufficient for the whole queen mating
season.
Mini Mating Hives are as the name describes, small mini hives, with
small frames in the order of 6 inches square, often just 4 frames and
an internal feeder of some sort. We made our own to the D.E. standard,
but of late styrene hives have become available. Click
here for photographs. These units can be sealed to prevent flight,
have an internal feeder and the frames are of the 'top bar' hive design.
A simple bar with a slit into which a strip of foundation can be set
with hot wax.
Adding bees to these units can be a trifle difficult as there is
an immediate return of bees to the donor hive, shaking bees from open
brood is ideal. These bees having never left the parent hive stay
where you put them, unlike field bees that will try to return home
back to their parent hive after their first flight. We found, after
a great many false starts and failures, the ideal method is to shake
bees into an empty box, spraying them down lightly with a 1-1 sugar
syrup, to which we add Vanilla flavouring. This helps to prevent fighting,
allows the bees to intermingle easily and produces a cohesive mini
hive.
Prepare the units, making sure the entrance is screened to prevent
flight, ventilation is a must, have the cells to hand. We use a styrene
carrying unit with a number of holes into which we place the cells
with their respective cell protectors. Our method of adding bees revolves
around a flat bottom boat bailer. We first fill the feeder, add a
ripe cell complete with cell protector, then using the bailer we scoop
a good number of bees and drop them into the mini hive, waiting until
the bees move off the top bars to prevent crushing, add the roof.
We now set these units aside in a cool dark place, in deep shadow
will suffice, a basement is even better. We move our cells on the
14th day from egg laying which then requires another 48 hours to emergence.
As a matter of course we add a further 24 hours to make certain the
virgin has emerged and at which time she will produce small amounts
of pheromones. Now the bees can be allowed to fly freely, in the area
where drones can be found.
On releasing the screen we always add a handful of grass in front
of the entrance to confuse the bees and prevent the loss of any flight
bees. From this point the results are a gamble. The virgin should
go out on mating flights after the 3rd day, assuming she has a successful
flight, and meets approx 15-17 drones, and escapes any birds, then
egg laying should commence in a further 3-4 days. The signal for a
successful mating would be eggs, but it's also possible that she does
not fly to mate in which case she will invariably turn into a drone
laying queen. In my experience when a virgin fails to mate and becomes
a drone laying queen, then her body is noticeably smaller, possibly
due to the lack of sperm storage.
At one stage of our Queen Rearing discovery we used to remove the
emerged cell as soon as possible, resulting in a large amount of 'laying
workers' if the queen failed to return from her mating flight. Now
we leave the open emerged cells in the hive until we are ready to
check for eggs. It is my opinion that the release of Royal jelly into
the food chain, as the workers will clean up the Royal jelly left
by the queen, helps to prevent 'laying worker' formation in hives
where the queen is lost to mating flights. We have noted that some
hives will die out waiting for a virgin to return, as others, where
we removed the open cells quickly will turn 'laying worker' much quicker.
Our general practice is to harvest the new laying queen and immediately
replace her with another ripe cell. Using this practice it is possible
to raise a constant supply of queens all summer long. Gaps in replacing
queens will result in 'emergency' queens being produced, which should
be avoided at all costs.
An old wives tale states that "incoming queens will destroy any
cells being produced", this is incorrect. Only incoming virgins
will do that job. Mated queens will get down to the job of egg laying
so any cells already in production will be allowed to progress, ultimately
the virgin emerges and kills off the queen recently introduced. So
in all cases of transferring queens ensure that cells have not been
started in the recipient hive.
All new queens should be evaluated quickly. Our general practice is
to transfer to a full hive and allow a full 14 days to check the pattern
of her egg laying which should be a full slab with few if any raised
drone cells. Newly mated and transferred queens will not lay drones,
so any raised caps show an improperly mated and suspect queen.
At the end of the season it is a fairly simple measure to store the
units for the next year. We first remove all queens and any subsequent
brood is checked for stray cell production which we prevent or remove
all started cells. It is imperative that all brood be allowed to emerge,
live brood placed into storage will die and create a foul smell.
Then the Mini Hives are moved closer to our full sized hives and the
bees are shaken out, they will be taken in by the full hives. If the
mini hives are stored without removing the honey stores, then open
honey will ferment and run out the entrance in storage. The simplest
method is to allow the full hives to 'rob out' the mini hives. I have
always frowned on starting robbing, as it can get out of hand and
destroy small nucs. In this case it does not appear to happen, I believe
it is because the mini hives are so much smaller and a different shape.
If you are following these instructions there is no reason why you
cannot raise good quality queens all summer long. Just watch for a
nectar dearth as it will create a problem with the final quality.
