Tested Open-Mated Daughters of Hygienic Breeder Queens DescriptionThese queens are reared from hygienic breeder colonies which we have tested using the freeze-killed brood bioassay and which are highly hygienic. After mating, queens are set up in hives at LASI and allowed to lay eggs so that 2 months later the workers in the colonies are daughters of the new queens. The colonies will then be tested 3 times using the freeze-killed brood removal bioassay. Only queens which test as highly hygienic (>95% removal of freeze-killed brood) will be supplied. These queens can be used as breeding stock by queen rearers and beekeeping associations If you have any enquiries regarding your order please email [email protected] Tested Open-Mated Queen Batch - 25th May 2017 |
