Reports on the effects and eventual resolution of a nosema episode are all
over the map.
Some say it has little real effect on the performance of hives and will resolve
itself if conditions are agreeable, others claim it is deadly and a one-way trip
to hive death.
Such a divergence of opinion says to me that nosema is not the core problem,
but merely the most easily identifiable one in situations where nosema seems
to be destroying hives.
Also, as someone pointed out recently, nosema, like mites, causes punctures
in the bees in ways that opens them to invasion by many different pathogens.
My advice, and it is contrary to most I hear, so take it for what it is worth, is
not to worry about decontaminating equipment, but rather strengthen the
bees against disease and look to other measures like
1.) improved conditions (hive strength, shelter, reduced beekeeper
manipulations, etc.) and
2.) give them an advantage by requeening with superior, hardy, hygienic stock
and
3.) by providing guaranteed nutrition at all times by ensuring the hives have at
least enough feed in frames or feeders to last several weeks and
4.) by providing protein supplement where there is any reason to suspect
monoculture or poor quailty pollen forage could be providing less than idea
amino acid balance.
