>>You may be correct about the field-realistic exposure levels, yet we
find that for some viruses, we can't reuse the combs. In 2010, I put the
combs from a collapsed colony into an observation hive wired to monitor bee
flight activity. Within 3 months the collapse played out just as one would
expect. Best that we could determine, the bees introduced were thriving when
placed into the hive.
So, from a day-to-day practical application, does this mean we should not
reuse plastic foundation brood frames? I still use beeswax foundation
brood frames and replace them typically when a colony dies for some "unknown"
reason.
What about plastic foundation honey super frames? I typically run beeswax
foundation brood frames that I replace on a five year rotation or when a
colony dies for some unknown reason. However, I run plastic foundation in
my honey supers.
Replacing frames is expensive, but sure beats having viruses in the colony.
