Newest data from our lab indicate the lethal temp /time combinations for adult bees
are 52 C for 9 min,  49 for 15 min and 47 for 25 min.  Strangely I did not see any data
on this for either bees, nor mites (even though many people in Germany use a
certain temp to cook brood to kill mites, no data was given for a safety window for
bees).

we have not done brood yet.
