just to update the current status of selective breeding for mite
resistance in my 2 yards.losses in yard #1 ,5 out of 20 ,2 crashed as
the result of casting large ,late swarms.Yard #2 losses were zero of 37
hives.method of selection=highest production,survival through winter w/o
treatment,clean bottom boards.temperament was not considered ,only
production and survival.stocks used were hives removed from walls,swarms
collected,and existing stocks.winter losses showing decrease yearly from
25% four years ago to less than 10%this year.cause of this years losses
of 5 hives not verified as mites.no treatment of any type used last
year.
