Apparently not so. When the queen of a hive that was coping well with Varroa was introduced into another hive in a new location, the receiving colony did not develop the same anti-varroa behaviour as the original colony. This could be the reason why a strain of bees that has found and marketed as being resistant to Varroa performs poorly in other areas - obviously there is a lot going on that we don't understand yet.
