I looked at your website.. If I read correctly, it seems likely that your bees may have requeened-perhaps multiple times- while surrounded by the bees of the migratory beek. This of course would mean a dilution of your genetics.It doesnt preclude the possibilty that you are on the down side of what may be a pathogen-bee dance, or some "new" pathogen, but I would expect degradation based on dilution alone(of course the severity would depend on the genetics of the migratory beeks bees).
