> What about a shorter time for bee emergencia in the case of Scutellata >
versus the  european bees? I understand is closet to 19 day rather than 21
In warm weather, the period is closer to 19.5-20 days for Europeans.
But it's not about total development time -- it's a matter of the duration
of the postcapping duration period.
Allsopp found that shorter postcapping duration of capensis was enough to
give it an advantage against varroa over scutellata.

As far as mite hyper-reproduction after treatment, I've never noticed it.
