I agree. My mite counts tell me my mite threshold is much higher than the local average of treated hives´mite infestation when they should be treated.No, anything I have to treat I don't want. Its a propaganda point that a universal threshold exists. Lots of my hives survive with phoretic fall counts in the 10 percent range. The ones that don't have virus issues probably and I don't want those either. But you don't know until you go tf and see how colonies respond. I am not worried so much about the hives with brood counts in this range. I am worried about lots of expression of dwv and the higher counts. So I put on robber screens on all my production hives to protect the better hives. I will make queens from productive hives that have lower mite counts and survive 2 or more winters.
Bees dont abscond due to a mite load, they die.
Very informative write up: however, in my climate the bees will abscond when the problems arise. The difference may be that they are responding to hive beetles taking over and sliming the hive as it weakens due to the failed or failing queen. This occurs primarily in the mid summer to fall time frame, fwiw.
I don't see dead or sick bees before this happens. I will grant that the problems start with the mite build up, but I think the end comes sooner in tropical climates where the SHB thrive year round.
Wrong link?"Anatomy of a Mite Crash"
This is a really interesting topic!
But you know I was looking at this video and I can't tell which ones are the Varroah and which are the foulbrood crashing the hive (see link below)? I'm still new to this and figuring out the different bugs from each other.
