  4. Re: How long a brood break is sufficient to break mite cycle

    That is the annual cycle of the original host of the varroa mite, the Cerana bee:

    57131

    So 3 months of varroa reproduction (in drone cells) – which means a brood break for 9 months.

    Also...
  5. Re: returning wet supers after extracting; how to avoid robbing frenzy?

    Wet supers attract moths more than dry ones, at least here where I live. Also wet honey supers must be kept dry and can't be stored outside, because of the air moisture. Activates the yeasts. So in...

    Re: Is it possible to graft too young?

    Frank is right. It is often the operator of the grafting tool that damages the larvae.



    Honey and water? Why is that? For good results use pure royal jelly.

    Results haven't been very impressive. It never made into serious beekeeping.

    Yes, one shipment. I ship them regularly and with great success. No nurse bees needed. Just a damp paper towel, a sheet of plastic on top, so it doesn't dry out too quickly. Done. Overnight parcel...

    Re: ...so whats being done about hive theft?

    The first pallet of the row should fall apart, when you lift it. (Or for the smaller beekeeper: the hive bottom) Bees will take care of the thieves. :-)

    Re: Is it possible to graft too young?

    There is not a single larvae on that picture that I would graft from. All those larvae are way too big. Even the one labeled too small.

  19. Re: German Black bees in the Southeastern US actually Apis mellifera iberiensis?

    How do you recognise black bees: if they have a brood disease of some sort, it is a black bee. I tried so many varieties and all of them were very susceptible for brood diseases.

    Re: Increase low hive population

    It makes no sense harming (weakening) strong colonies for an already dead hive.
