Right now, my concern is getting these hives queen right and with enough honey and brood to survive our wet, long winters. Varrora cycle, if I have it, is broken by not having any brood. (Just recently learned that by breaking the brood cycle for a short period of time, simulating winter, and it breaks the mite cycle, WSU study)
It was kind of interesting, as each new hive had more than one virgin queen just emerging when I did the splits. Also, really interesting, is that the hives stayed mellow without queens.
