At a recent meeting of the Ohio State Beekeepers Association, Dr. Jim Tew was the keynote speaker. He asked the participants how many had lost >50% of their hives; a third of the group raised their hands. He then asked how many had no losses and 15-20% responded. I am curious if the Bee-L subscribers have had similar experiences. Does the use of Apistan or other medication correlate with winter hive survival? I use Apistan prophyllactically, but I know many who don't. Thanks for any info. John Oldfather [log in to unmask]
