    Re: what kind of bee diseases is this

    Probably a virus associated with a high mite load. deformed wing virus or one of the paralysis viruses are the most likely suspects.
    You also get crawlers with tracheal mites.

    Re: Bees criteria to choose queen larvae

    Honeybee abdomen colour is not governed by a single gene dominant-recessive scenario.

    Didn't Bernhard post something recently about brood nest temperature having some influence on bee colouration/darkness. Maybe there are other factors in play as well.

    You can see the virgin leave and fly back to the apidea in this video.
    This was a brief orientation flight rather than a mating flight.

    Re: Small Scale VSH genetics and hybridization

    I use Apideas (mini nucs with a few hundred bees and a virgin queen)
    I have seen a virgin leave the Apidea accompanied by the bees which I presume is a mating swarm.

    That has been disproved experimentally many times. Sperm in the queen spermatheca is completely mixed.

    Re: my apple wine plan

    I don't think you have enough honey or sugar in there.
    3 1/2 lbs of honey per gallon makes a 12% wine.
    Also, you might need to let it sit for a bit longer before adding the yeast or the Campden...

    Re: Benefits of Queen Wing Clipping?

    My vote is to clip. As Bernhard said earlier it gives you a second chance to prevent losing a swarm assuming you van check your bees at least every 2 weeks.

    Re: Benefits of Queen Wing Clipping?

    Carniolans look a bit greyer than Amm when you compare them together.
    The bands on the abdomen are a bit wider as well.

    Apis mellifera mellifera queen.
    The queens, workers and drones are all very dark.
    It is our native bee in Ireland.

    I have clipped queens which last until the 4th season. Never seen a problem with it.

    Mites prefer drone cells over worker cells because the 3 day extra development times makes a huge difference to the number of viable daughter mites produced by each female foundress mite.

    That is a good recipe for producing a high percentage of diploid drones. You might want to read up on csd locus.

    Re: VSH bees and hybridization

    What do you mean exactly by 61 untreated hives 4th year?
    Surely most of these are swarms you collected in 2014.
    You said you had 27 hives in April
