    Default Nosema ceranae?

    For Germany our scientists said that they didn't find this kind of nosema in dead hives/bees.

    so it is yes in spain and no in germany?

    I understand they were looking at Bt contamination in germany? any news from your side of the pond on this possibility?

    This is the 1st I've heard of any potential problems with using Bt in beehives. Has anyone heard any cautions about using Bt to control wax moths in supers? I'm about to treat all my empty supers with Bt and I'd sure like to know if anyone has heard anything. I'll be using the Bt aizawai powder that is advertised in the For Sale section here on Beesource.

    Thanks,

    Tim

    beemeister sezs:

    tecumseh replies:
    well beemeister rather than the product itself (which I understand is sprayed on combs and I think was at one time sold under the trade name certaan-sp?), the unlikely suspect in this case is a gene attached to any number of crops and questions have arisen about possible contamination to the bees from these crops pollen and nectar. so the hypothesized route would be somewhat different-direct contact by adults vs feeding to the larvae.

    I had heard, via a customer-genetic professor, that there was some concern in germany since rapeseed was one of the first crops where Bt was spliced into the plants genome. it is my understanding that any number of other crops have now had the Bt gene spliced onto their genome...cotton, corn...

    in regards to using Bt as a wax worm preventative (studies suggest it is not totally effective) I would really not loose much sleep over contamination when using it directly on the comb.

    Thanks Tecumseh for the information. Now that you mention it, I had heard about the gene splicing. It's been discussed here on Beesource! My memory just needed a little prompting.

    Thanks again.
