    Default Honey b Healthy / Nosema

    How many of you have switched or use HBH Drench instead of fumigillin?

    How many can say you wiped out Nosema with it?

    Do you think its better than fum-b?

    Did you try it and go back to fum-b?

    Does the drench work?

    I have heard HBH Drench makes fum-b look silly.

    I tried HBH, don't think it did anything for nosema, although i didn't have lab tests done.

    IMO There is no lab tests that prove the allegations that HBH takes care of Nosema. To be honest i dont know why anyone would pay $24+ for a bottle when you can make your own right at home. But everyone does things differently! I use fumagilan-B for Nosema "when needed"!

    If one doesn't do before and after spore counts from field bees there is no way to answer that question.

    You can find reports that everything works, and also that nothing works


    For what its worth:

    That study was probably sponsored by HBH. Let us not forget, HBH is a nutritional supplement, not a medication.

    It was in an article earlier this year, several large commercial beekeepers where claiming it really helped. Some of those beekeepers are now dealers of HBH.
    The article was independently written. I bet we see some research done in the next year on whether or not it helps.

    Thanks for the article LoggerMike.

    I'm skeptical, because as an ex commercial beekeeper I know all the anecdotal type info in the article, can just happen anyway.

    However, it got me thinking enough, that I'll use whatever remains of my EO's this coming summer, "just in case".

    Thats right . A flow coming on or a return to warm weather can turn things around. Thats why its so hard to tell the results of a specific treatment without some kind of measurement. We might be making wrong assumptions.

    A lot of us have been hit with above average losses and N cerana always seems to be in the mix(along with almond pollination). So it needs to be dealt with, as nature is doing a piss poor job of it.

    Down in the almond orchards this last February, I was talking with an old beek that had lost more than half his hives. He said he had put in all new queens, fed pollen sub,controlled the varroa and fed fumagillan. He said he did everything that the experts said to do and still lost big time.
    I mentioned the essential oils and he said:
    "The trouble is, that stuff never works like its supposed to"

    Yes, I don't think that there is much doubt that N cerana is a major problem and will certainly be a serious "part of the mix" when the bees are already stressed by other factors.

    The problem is, how to deal with it.

    Long term, I think the solution will be genetic, and that's what we should be aiming for.

    Are they using the nionics in the Almond fields if so this may be of interest to your friend.

    Summary
    Global pollinators, like honeybees, are declining in
    abundance and diversity, which can adversely affect
    natural ecosystems and agriculture. Therefore, we
    tested the current hypotheses describing honeybee
    losses as a multifactorial syndrome, by investigating
    integrative effects of an infectious organism and an
    insecticide on honeybee health.We demonstrated that
    the interaction between the microsporidia Nosema
    and a neonicotinoid (imidacloprid) significantly weakened
    honeybees. In the short term, the combination of
    both agents caused the highest individual mortality
    rates and energetic stress. By quantifying the strength
    of immunity at both the individual and social levels, we
    showed that neither the haemocyte number nor the
    phenoloxidase activity of individuals was affected
    by the different treatments. However, the activity of
    glucose oxidase, enabling bees to sterilize colony and
    brood food, was significantly decreased only by the
    combination of both factors compared with control,
    Nosema or imidacloprid groups, suggesting a synergistic
    interaction and in the long term a higher susceptibility
    of the colony to pathogens. This provides the
    first evidences that interaction between an infectious
    organism and a chemical can also threaten pollinators,
    interactions that are widely used to eliminate insect
    pests in integrative pest management.
