    Re: Dead bees with small/short abdomens

    It was the comment in the OP about no stripes like the rest of the workers which made me think maybe black shiny bees.

    Re: Dead bees with small/short abdomens

    Bees should not be defecating inside the hive unless confined in there for long periods, but I would imagine you are right and a mesh floor would be a help.
    I think dead bees which have succumbed to...

    Re: Dead bees with small/short abdomens

    That was a big surprise for me as well as I tend to blame most bee problems on the mites.
    I saw this problem in one of my Apideas (mating nucs) in October.
    At the time it only had a population of...

    Re: Dead bees with small/short abdomens

    This is a most likely a paralysis virus.
    The short abdomen is characteristic.
    It is transmitted by bee feces rather than mites.

    I saw this a couple of years back and sent samples to a contact in...

    Re: Back to square 1

    The problem with isolation starvation is not so much that there is brood in jan or feb, it is usually due to the cluster being too small.
    A big cluster can generate heat and bees can move about a...

    Re: bispham's causal chain

    Puncture wounds are clearly one of the primary means of transmission but the paper posted by JW did point out that:



    DWVv is the virulent DWV variant which causes the problems for bees.

    Re: Do I need to undo today's split?

    14 linear inches?
    Make the entrance 2 or 3 inches at most.
    If you suspect robbing make it a lot less than that.

    Re: bispham's causal chain

    Mike. You can't have looked at the Martin paper yet.
    JWchesnut gave a link to the full paper a few posts after mine which had only linked to the abstract.
    DWV exists in many variants. It is there...

    Re: Back to square 1

    Prime suspect though if they were untreated.
    Mites can lead to shorter lived bees and dwindle and then in the end the small cluster just freezes or starves. The small clusters are very prone to...

    Re: bispham's causal chain

    That is correct. The transmission of some of the paralysis viruses is not related to varroa. Bee fecal matter is implicated.

    Re: bispham's causal chain

    That's not the case. The Martin paper explains that right from the start. DWV is present in many variants in bee populations without mites. When mites arrive this favours the tranmission of one...

    Re: bispham's causal chain

    The point I was making, which you surely know and are avoiding, is that transmission is not just about puncture wounds.

    Re: bispham's causal chain

    You made a claim about virus action and 'open wounds'. You back it up with evidence or a reference. Both the papers are open access. Go read them for more detail instead of making stuff up.

    Re: bispham's causal chain

    That is incorrect. If you read the two papers jwchesnut provided a link to in an earlier post and you will get more of an idea about how viruses and mites interact.

    Re: Virgin Queen ID

    If a queen did not mate before the winter she will not mate now. Queens usually mate within 3 weeks of emergence although on rare occasions they can mate up to 4 or 5 weeks after emergence. She...

    Re: Hives Died in less than a Day. Why?

    Are there any stores in those combs? Hard to say looking up from the bottom but they look quite empty.
    Also, all the visible capped cells are drone cells so maybe there was / is a failing queen.

    Roundup on its own is harmless for bees. Beekeepers spray right up to hives with no ill effects.
    Could there have been residue from some other product in the sprayer?

    Re: Happy Birthday Michael Palmer

    Hi Michael
    I raise about 250 queens per year and I also overwinter nucs so those two presentations were perfect for me and I picked up quite a few tips. I am encouraged to scale up a bit more.

    Happy Birthday Michael Palmer

    Just had the pleasure of hearing Mike Palmer deliver two talks in N Ireland earlier this evening.
    The sustainable apiary and queen rearing in the sustainable apiary.
    Great stuff.
