Simoneau André asked: Has anyone on this instructive list ever heard of research or even trials on the efficiency of Acaromyces laviae against Varroa destructor. I heard it was used in Europe, in the 50's to fight effectively(?) tracheal mite. I know that some very promising research has been carried out on the use of fungi to control varroa at Horticultural Research International (HRI) - not sure about Acaromyces laviae, but you may be able to get an update.
