I'm interested in hearing your suggestions as to alternatives. All
the unmedicated hives in my part of the world have already died. Bee
pollination is crucial to many branches of agriculture. No magical
cure for Varroa is available, or we'd all be using it. My jaw
practicaly hit the floor when I heard the price of Apistan. For
people like me, with only a couple of hives, beekeeping has suddenly
become very expensive.

I don't have my package of Apistan at hand, or I'd tell you. You
can call up a beekeeping supplier, and they'd probably read you
the label over the phone. Then you call the manufacturer, get a
data sheet, and maybe talk to one of their scientists.

We quickly ended up with methol-resistant strains. (What a surprise!
When will we realize that resistance is a *predictable* outcome of
pesticides?)

I don't know. I don't get the journals, and I'm way behind in my
reading of the popular press. You could probably find some of the
researchers with a Web search on "Varroa." Ask 'em.

I would think that the bees in national forests and other extremely
remote parts of the West would have survived if this is the case,
but it's my understanding that they're all dead.

You ought to do a literature search. I am not up on the research,
but I'm under the impression that a great deal is going
on. Some of the work will be on-line, which is handy if you're
not near an agricultural college's library. There's nothing like
reading thirty or forty papers and an equal number of articles
in the trade press to get an idea of what's going on in a
field.
