|Stephen Martin Professor Emeritus Sheffield University is carrying out research into how honeybees are reducing varroa mite populations by uncapping and then recapping brood cells. Bald brood in a straight diagonal line is the wax moth, but cells which have been uncapped in an apparently random fashion have been done so by the bees trying to detect varroa mites. If uncapped at a crucial period the mites are unable to survive.
It would be useful to photograph these uncapped cells and discover whether they have been recapped at the next inspection and also how to recognise this uncapping, which apparently goes on far more than the beekeeper is aware. This is an excellent trait to have in your bees and an ideal colony to breed from.
