I believe this is the guy who made the headlines a while back about finding a new hygienic behavior. Many said he just found more of what we already have. However it appears he has found a strain or gene that actually gets the bee to be a more aggressive groomers to the point they end up pulling of antenna of other bees when aggressively trying to groom off mites. He moves a queen with the gene to a highly infested hive and soon the mite population dropped. This would be another great addition to our mite tolerant arsenal.
