I don't know how carefully you read my posts, but one of the interesting things
I mentioned is that I had indeed obtained a number of strains of bees with
reputations for having resistant traits. They died just the same as all the rest.
I obtained stock from several sources in hopes of improving my stock and suspect
that something came along with it.
What I am thinking is that there is some novel pathogen which is going around
and kills entire yards when conditions are right.
I am suspecting that all those bragging about how clever they are and how they
need not treat have just not encountered whatever it is that is killing bees or
not experienced the conditions which allow it to avalanche.
What are the odds? For a small operator, much less than for a large operator.
Although luck allows the small operator to feel smug, the large operator knows
the cards are stacked against him due to greater numbers and more locations
and has to be much more proactive.
Chance is a hard thing to understand and impossible to measure except over
large numbers -- and even then we know that we are dealing with finite samples.
I have had entire yards die over winter before, but because I had many more
yards to average over, the winter loss only averaged to 15% for the outfit.
Looking at just a few yards might suggest disaster, but when the final numbers
are tallied, the picture may look very different.
This was one yard.
