By following swarm capture rates and longevities of colonies established from swarms for 15 years, before and after the arrival of varroa in southern Louisiana, there were initial decreases in swarming rates and colony survival presumably due to varroa. This was followed by improvement of both measures after about five years with a return to pre-varroa levels of swarm captures and colony survival.  It was either a mirage, a series of effects confounded by other factors, or true effects that happened under the right conditions in that area.
