In the journal "Beekeeping" (No

In the journal "Beekeeping" (No. 3, 2013), I published a note about the coexistence of two queen bees in a single colony for nearly a year. Last year, the bees surprised me again. Learning about the beneficial properties of a queen bee isolator developed by Ukrainian apiarist P.Ya. Khmara, I created four such devices in winter 2015. On June 9, I placed queens in these isolators and introduced them into colonies. After 10 days, I checked for queen cells and found none; the queens in the isolators were alive. I continued to monitor the colonies until July 16, confirming the queens' survival without dismantling the hives.
