In your local (Sovereign lands)...?.. possibly.
Even in high density communities here the concerntration of managed colonies no way
approaches the saturation levels I read about for Europe and the Americas. One would
think then that DCA's would be part of our (.AU) known b'keep experience...?.. yet
"online" is all of the exposure I have ever had to such a concept.
Not at all disputing a virgin would - does? - fly past drones of her own genetics it just
does not stack up where in the time absent from her colony she is travelling and
mating outside of much more than a kilometre or two.
Equally drones require sustenance. Not known to forage beyond joining in on a free feed
of spillage it reads as fancifull human thinking for drones to be lolling about in specific
groups for the purpose of... this in an area well remote from homebase?
Closer to reality is the concept loose groups of drones embark on "kerb crawling"
behaviour upon the slightest whiff of a virgin on the wing.
Today (as management) I run three lines of genetics two of which are selected from
known suitable genetics the third is from "out there", bush bees (ferals) seen to be
hybrids of apis.m.Linnaeus.

Settling on the regime years ago was borne of teachings absorbed, my own experience
of random matings and interaction with others on their methods of maxing out production.
It is only "online" - a new experience for myself - I have come across the DCA concept to
wonder if, amongst the millions of beekeepers (globally) the detection of these areas was
known. I would welcome that teaching as how easy then would it be to maintain diversity
in genetics..! Pretty much every creek line and/or wooded valley (locally) owns more than
one "wild hive" yet over many years of beelining these I have yet to notice any particular
gathering of bees outside of cast swarms.
Given Apis.m has been 'farmed' by Man over many many generations I am still perplexed the
only developed recognition of DCA is "online".
