Here is a VERY interesting video. One lesson is that it might just be better to not use miticides! But there seems to be two conflicting ideas in the video. The beekeeper thinks its the genetics of his bees and his not using miticides for 20 years. The scientist is stating a second virus is out competing the DFW virus. Take a look and let us know your thoughts. I suggest you watch it several times to let the various ideas sink in.
