One beekeeper, queen producer from Montenegro (Europe) informed me that all
his colonies in his bee yard become much more aggressive during this
season, in comparison to last year. He would like to know the reason. He
said, he could understand one or few colonies become aggressive because it
happened eggs were fertilized with the sperm of drones that have aggressive
behavior in genomes, but it would not be possible to happen in the whole
bee yard in the same time.
I think that could have an outer reason, but am not sure what is the exact
cause: magnetic field, electromagnetic waves, different energy fields....
or something other.

I will be thankful for any input.
