>But oppressive 80% humidity is common at NAS Pensacola, do beekeepers near
there have less varroa issues?

Kraus's study is cited again and again, but to the best of my knowledge,
has not been replicated.
If true, then varroa would not be expected to be able to reproduce to any
extent once ambient humidity exceeds 80% and ambient temp exceeds broodnest
temperature, since the bees would not be able to use evaporative cooling.
When I've queried researchers and beekeepers from areas where such
conditions occur during summer, none have yet reported that they observe
varroa reproduction to cease.
