More Stoneleigh

Brenda Ball of Rothamsted spoke at Stoneleigh of some intriguing findings in varroa-hit colonies in New Zealand.

In untreated colonies that succumbed to varroa, they found surprisingly few signs of viruses. And none that seemed to be the cause of the colony death. However they did find some KBV (Kashmir Bee Virus) and it did seem to be “associated” with colony deaths. And the KBV is similar to the Canadian strain. It's a bit of a puzzle.
