I noticed in April, than tens of mites dropped from a comb. Mites were trickled half year ago.

Cluster was not yet active and they clean the cells when the colony expands in spring. That is why you may get big natural fall in spring.

Finman did he do any sublimation and are there any written results?

No sublimation. I do not know how they are written. I got this data 10 years ago and I found them from internet.

These are guys whom I trust.

The study was carried out in year 2000 by someone named Wohlei, using Perizin as a control, reported by Jean-Daniel Charrière, who works at the Liebefeld research centre


OA spray means that 3% OA water solution has been sprayed onto each comb side which are covered with bees.
