    Re: The Roundup Thread

    It is used in plant nurseries and can be spayed on quite a few plants that are not actively putting out new growth to kill the weeds. Although (if used at the right dosage) it does not kill the crop...

    Re: The Roundup Thread

    I don't think that it is a big deal with bees, but it is being found at increasing levels in groundwater. It breaks down in soil, but is fairly stable in groundwater. The MCL of 0.7mg/l in water...

    Strange how caged bees can drift between colonies and go out to forage on crops.:






    How do you test for a substance that is known to be below detection limits of a testing procedure?

    Re: Terrence Ingram - 11 Hives Destroyed by the IDofA

    It could be true, but I would think that a positive lab test with multiple samples would negate that argument.

  11. Re: Raise a queen? - when #8 hardware cloth between brood boxes

    I'll bet they make queen cells.

    When a bee emerges, she and her sisters do not normally leave their comb until they eventually gets displaced. The rest of the hive is still foreign to her and...
  12. Re: Raise a queen? - when #8 hardware cloth between brood boxes

    The bees will usually raise another queen if the brood boxes are separated. You need an upper entrance. You don't need hardware cloth. 2 supers of comb (or honey) in between the boxes of brood...

    Introducing a Queen in a Queenless Hive

    I was wondering if anyone has ever tried this method of queen introduction. It is one one of Doolittle's queen introduction methods. Maybe it would work in a hive of laying workers?

    Re: Is entrance reducer neccessary?

    A 1" hole is too big to plug with a wine cork. 7/8" is a good size since wine corks will fit. I use a half cork opening in the winter.


    1/4" will cause the bees to lose a lot of pollen loads.

    Re: Hive dimensions

    I don't think that the depth of Langstroth's hive was related to the lumber dimensions. The depth of the original Langstroth frame was what worked with a 10" deep glass hive.
