> You know, at one time people thought that wax moths killed hives
It's likely that when wax moth first invaded North America that it did
indeed kill hives, as the bees may not have recognized it as an invader,
and thus would not have had a colony-level "immune response."
>So the burden of proof is one the one that says that nosema is a
significant factor in the loss of bee colonies and it is up to them to
prove that it is.
As you well know, Pete, it is impossible to "prove" that. However, we can
attempt to disprove the hypothesis that it does contribute to collapse. At
this point, I'm seeing suggestive evidence to the contrary.
