That's an unexpected statement, what did Mr. Martin say?

A long-term (and still ongoing) study on a reasonably large number of
hives at several apiaries by Dr. Wyatt Mangum of Virginia, USA was
said by Wyatt last summer to show that reinvasion (or "inter-colony
drift", if you will) IS the apparent primary means for spreading varroa
between hives.

We should introduce these two and let them compare data.

I can vouch for Wyatt's data, as he collects it all himself from
mostly his own hives, and he is a math professor, so his statistical
work is known-good.
