    Default dsRNA ingested by bees is transferred to the Varroa mite and from mite on to a parasi

    Bidirectional Transfer of RNAi between Honey Bee and Varroa destructor: Varroa Gene Silencing Reduces Varroa Population
    We previously reported that honey bees fed on double-stranded RNA (dsRNA) with a sequence homologous to that of the Israeli acute paralysis virus are protected from the viral disease. Here we show that dsRNA ingested by bees is transferred to the Varroa mite and from mite on to a parasitized bee. This cross-species, reciprocal exchange of dsRNA between bee and Varroa engendered targeted gene silencing in the latter, and resulted in an over 60% decrease in the mite population.

    Interesting study, I wonder why they only got 60% control though, that's not very good when using that kind of an approach.

    Hopefully they can keep their genes from infecting the rest of the bee population. Until we really know what else it does.

    And if it really works we can all buy our bees from monsanto for 5X the price.

    Flower, it's a topical treatment or in this case, it was fed to the bees, has nothing to do with genetic modification of the bee. There is no gene expression either, the rna does not replicate.

    Yes this is real good...Monsanto applying for a patent...We'll see how much bees cost when your queen mates with a drone with this newly acquired Monsanto DNA and your making splits and nucs for sale. Hope you have deep pockets. For all those hoping for a godsend this is not it. You will have to pay Monsanto to raise bees and if not pay heavy fines..can you control your drone yard? Good luck!
    Think about it....Buy American

    Spark, has nothing to do with genetically altered bees or patenting bees. The patent is for the sequence(s) of dsRNA's used which target mite genes, nothing to do with bees. The bees were just a vector of the dsRNA.
