My apologies [plural], Lionel.

SBB: Screened Bottom Boards; VD: Varroa Destructor—not to be confused with
SBB: Screwed Bottom Beekeeping or VD: Venereal Disease, resulting from
such practice. :)

Seriously, Lionel, why don't you tell us more about Southern Beekeeping,
in general, which differs from the northern one [most of the bee books are
written by uninformed northerners, in fact], and the increasing feral
swarms in particular, for I am a believer that Russian or no, there ARE
feral colonies, surviving through all this, an experiment much harsher
than any scientist can impose in his/her lab [I mean laboratory], a fact
that fails to draw much attention from “mainstream” beekeeping.

I sure also appreciate if someone with a glass-top, like Denis, who can
examine the airflow inside the colony on a screened bottom board: smoke
lightly at the bottom and see the flow.  Such flow chart will help
determine the efficacy of, say, oxalic gassing, among others.
