An Introduction to Queen Rearing

Honey bee eggs and young larva

As you can see in this great photo by Jeff LaSorsa You will most easily find the best larva for grafting – rearing queens from – by looking at the ones between unhatched eggs and larva that are too old for grafting on a frame of regular worker brood. Notice how easy it is to see eggs and brood on black plastic foundation.

 

This article was originally published in 2011, but because of the recent queen rearing field day I have moved it back to the front.

There are a lot of reasons why a bee keeper might want to produce their own queens – to save money, to propogate bees with particular qualities, or just because it is an interesting thing to do.  Queen rearing will probably elevate your understanding of honey bees to a new level.

This article is derived from a more detailed one on my blog  – Beginner to Beginner Queen Rearing.

This has been only my second year raising queens at all – my third year keeping honey bees.  So  I am in no way pretending to be any kind of an expert – not only have I made many mistakes, but I expect to make many more next year.   As one beginner to another – I think I might have  some useful insights into getting started in queen rearing.

I’m going to give several  beginner-to-beginner tips in this article.  Things that might not be all that helpful to old hands but have really helped me.  Here’s the first – and I think, best:

Plan to practice  rearing queens when it’s easiest – during the main flow/swarm season, that is – late April/Early June in Mid TN – when the bees want to reproduce.  It can be done earlier and later, but it’s a lot more difficult.

The Basic Principle of Honey Bee Queen Rearing

Any queenless hive of honey bees will try to make a new queen if it has the resources to do so.  The required resources being  1)  larva of an appropriate age 2)  food 3)  A sufficient number of worker bees 4)  Drones – male bees – that the new queen can mate with.  Most of the time such a hive  will be successful in requeening itself.   The reason this is possible is that the only difference between a worker bee and a queen bee is the amount and type of food that they eat during the first few days after hatching from an egg.

So  if you want to raise a new queen, all you really have to do is create a hive without a queen  which has eggs or very young larva, and let the bees do the rest.    This is called a split and it  is a fine way to increase the number of hives that you have.  And it’s exactly what I (mostly) did to go from 1 to 10 hives during my first 2 years.

A frame of foundationless brood with “emergency” queen cells on it.  Ever heard that foundationless brood always has lots of drone brood on it?  Not when it’s drawn in a queen-right mating nuc.

The problem with making a split is that even though your queenless hive will probably make several queen cells only one of them will get a chance to fly out and mate – because the first one to emerge will kill the rest. And there is a significant chance that one won’t make it home either – many get eaten by predators, lost, or caught in bad weather.  So after committing a strong queenless hive to the project for about a month at best you only get one queen – and there’s a fair chance that you won’t even get one.

Also high quality queens must be fully fed, and immaculately cared for from the time they hatch from the egg – any queenless hive will do what they can with what they have, but you want your queens to be raised under the very best of conditions.  And that takes a lot of well fed nurse bees – hundreds per each queen.

Queen Rearing – is a process whereby   one strong queenless hive  produces many well fed/well grown queen cells at the same time, and then before they emerge and kill one another  they are each given their own  “mating nucleus” hive to emerge into  and head up until they are fully mature.

Worker cells lay horizontally in the hive – queen cells hang down vertically in the hive.  When nurse bees encounter larva in cells that hang down they tend to treat them as queen cells.  This concept is central to most queen rearing methods.

 

Using such a process one “Mother Queen” with desirable properties can produce many – in some cases thousands – of high quality daughter queens.  You can use a similar system to produce a dozen or so good queens for your own use.  At $20-$40 each plus shipping for “store bought” queens  you don’t need to produce very many for it to make sense.  I would like to point out though, that after rearing queens myself a few times I understand why they are so expensive.  There is nothing all that hard about it, but there are several steps, and some of them absolutely must be done on a specific schedule.

A few Queen Rearing terms you should know:

Grafting – moving very young worker larva into artificial cell cups.  There are some graftless ways of producing queens    but you will probably want to learn to graft sooner or later, and the thing is – it’s way easier than you probably think. It just takes practice. Grafting is pretty much the only way the pros use to produce large numbers of queens.

Cell Starter – An extremely populous – usually queenless – hive that will begin the process of turning worker larva into queen larva.

Cell Finisher – After about 24 hours in the cell starter the cells are move into a finisher – Another populous (usually queenright) hive which will  finish feeding/building the queen cells.

Starter/Finisher – One hive that combines the functions of the starter and finisher.  The Joseph Clemens System uses a starter/finisher as does the Cloake system.

Mating Nucs – 10 days after grafting, the cells are removed from the finisher hive and each is put into their own queenless hives – mating nucs –  which they will emerge into, and fly out from to mate.  After mating the new queen will stay in the mating nuc at least until she is laying eggs  and fully mature – 3 weeks more or less.

mating nucs

Any queenless hive can be used as a “mating nuc”  You can use a full size established hive, or a full size setup with only a couple of frames of brood/bees.  Large operations sometimes use really tiny hives that contain only a cup full of bees.  They all have their advantages and disadvantages.  The mating nucs in the picture contain 3 medium frames. They are being fed syrup in mason jars through a matching hole in the covers – the coffee cans keep the sun from over heating the syrup and making it  leak into the hives.

Queen cells can be produced in small hives, but to do a good job they have to have a dense population of well fed young nurse bees.

You can start raising queens any time that you have drones, but it will be much easier to get good results – and easier period – during the main spring nectar flow/swarm season.  In our area of middle Tennessee Swarm season started hot and heavy during the first week of April this past spring so counting back from that date One could set up a starter/finisher hive about March 15 and grafted for the first time around March 20.  The truth is that the weather this April was very unsettled, and not the best for queen mating flights, but the early start allows  a little practice  before the prime queen production season – the month of May through early June.   Think about that when you order a commercial queen for early spring delivery – what was the weather like when that queen was trying to mate?  Another reason to raise your own.

    Thank you for posting all this great info! I cannot make the meetings on Thursday nights so I look to the website for more knowledge.
