I am hearing stories of big mid western outfits with 40% or more TM resistant
AFB.That means some of this has been and will be here in the 500 mile bee yard
referred to by Bhaver.So you had better believe other antibiotics will be
used,because only a fool is going to burn thousands of hives to stop what is
already unstoppable.How many hives were prevented from mite infestation by govt
restrictions?Absolutely 0.So this is a management issue,not something that can
be solved by regulation.Ok,Tm worked for 40 years in spite of all who said it
was a time bomb.If Tylosin works for 40 more,why worry?Yes  we should be
breeding for hygeinic behavior(some are).But realistically,the hygeinic lines
are going to always be crossing with lines that are being kept alive with
antibiotics.Same with mite resistant lines.Unless the breeder does as Aarron
suggests and does nonstop monitoring.Of course your stock will also be
affecting your neighbors line of bees also,so some progress will be made.
 So,IMHO,it is Ok to keep your bees alive with whatever it takes,but at the
same time look for and breed for those factors that keep the bees healthy
without intervention,just in case the new AFB treatments DO NOT last 40 years.
