Well, yes - to the mites swarming the new brood.Thinking of swarms and brood breaks. The swarm gets it's break, but the hive left behind is worse off than ever. It's like a hive in late fall, egg laying has stopped and the last brood is hatching into a hive with decreasing numbers of bees, piling mites onto decreasing bees. A month after a swarm, in the original hive, the new queen starts laying and those cells are going to be swarmed with mites.
Same with splits. If you pull a queen from a hive with lots of infested brood, the queenless half is going to suffer high mite counts.
This is all probably obvious to the experienced folks here, but it helps me to write it down while thinking about it.
Yes, I have seen what appears to be this happening, with multiple mites per cell. It is still a harsh situation for the left behind hive.Well, yes - to the mites swarming the new brood.
Well, not really to the mite count (as the overall estimates don't really change); the measured #'s maybe higher for obvious reasons - more phoretic mites.
But that was one main point of the Mel D's OTS method.
The over-whelmed brood gets killed by 2-3 mites in each cell (which in turn is supposed to be killing off mites or disrupting their normal life cycle - ???).
How the theory goes...
I posted a picture of how highly infested brood looks like (including a damaged queen).
Anyway, I have several hives this season that got double-brood breaks.
Is it bad? Or is it good?
Remains to be seen.
