In plain English, huh?
 
Sounds like you may have hit on a realistic answer.  However, in order to
overcome the continuous use of those anitbiotics, we must have someone,
such as yourself, extract some of that stingless bee DNA and start us all
over again.
 
This, of course, is based on the assumption that all the feral colonies of
bees that remain are descendants of some queen/drone that had been treated.
 Perhaps a more realistic approach would be to test a feral colony that is
of known age against a boxed colony that has been treated for generations.
Would the feral colony recover the organisms over time?  Could the feral
colony survive long enough to recover those organisms?
 
Is it possible?
