OTS Queen Rearing by Mel Disselkoen http://www.mdasplitter.com/ This web site contains many PDF files for additional reading.
Timing is important for quality summer queen rearing. Start no earlier than June 10 by making a split with the queen and notching, resulting in queens emerging and mating after the summer solstice. Summer queens should not be started after July. Queens raised from cells notched on July 31 will mate in mid-August. Queens started in August may be poorly mated as the drone population diminishes as fall approaches.
Selecting the best genetics for queen production enables a beekeeper to create survivor bees for a particular area. Initial selection may involve excluding a colony because it is too aggressive, weak or some other negative attribute. Selecting each year for good attributes will enhance genetics over time.
Determine if the hive is strong
A strong hive has 6 or more deep frames of worker brood. A strong hive can raise strong queens. Do not use a hive with less than 6 deep frames of brood to raise emergency queens because queen quality may suffer.
Find the Queen
Finding the queen can be difficult. She usually is on brood frames. Sometimes she is away from the brood frames or on the inside wall of the super. Be methodical and look at each frame. If you don’t find her today, try again tomorrow.
Make the colony queenless
Make a split using a nuc with two frames of brood and the queen. Shake one or two frames of nurse bees into the nuc. Move the split to another bee yard and reduce the entrance to a small opening. Feed the split. This split can be used as a new colony with the queen replaced later with a summer queen.
The now queenless strong colony will raise emergency queens.
Notch some worker cells
Check each of the four or more remaining deep frames of brood for young, less than 36 hour old, worker larvae. Notch about 12 cells of young larvae on each frame. Notching removes the bottom third of a cell all the way to the foundation enabling the colony to create a vertical queen cell. Don’t touch the larvae while notching.
Wait seven days.
Introduce Summer Queens
Seven days after notching inspect the hive for queen cells. One frame with two queen cells will used to requeen each colony with a summer queen. Leave one frame in the hive to requeen with a summer queen.
Start with the colonies that are weak or aggressive and inspect the colony to find the queen. Dispatch (kill) the queen. Inspect the frame with the queen cells and remove all but the two largest cells. Remove a deep frame and install the frame with queen cells.
Depending on the honey stores the colony may need to be fed. If there are frames of foundation that need to be drawn out feed the colony.
Inspect in 30 days for a queen. Plan on feeding starting in August to encourage brood production and honey storage.
What Went Wrong
If you don’t find any queen cells seven days after notching there probably is a queen still in the hive. But the queen was removed last week! Some hives have more than one queen. Everyone knows there is only one queen so they stop looking for a queen after finding one. A queenless colony wants to survive and will raise emergency queens if they become queenless.
Keep records of each hive with a summer queen and document how many survive the winter. Mel Disselkoen had up to 90% winter survival in Michigan before neonicotinoid use became significant. Next spring please email me with the data.
