Fixing chronic bee paralysis via requeening. Success and failures in the follow-up visits.

Over the years I've had pretty good success using re-queening as a fix for hives with bee paralysis problems. The worst case took two rounds along with mite treatments In this situation I felt foolish as last year I marked the emergency queen in this hive for replacement but failed to do so. Her mite resistance harbo assay score of zero perhaps opened the colony up to more viral risks. This is a long form impromptu unedited video so my apologies for the poor audio as I didn't have my mics.
