[QUOTE="Alastair, post: 5787, member: 13"] Pretty sure it is mite related. I would have been one of those high loss beekeepers had I not noticed when removing the bayvarol strips last autumn that many of the hives were still crawling with mites. I had to do several weeks extra work re treating nearly all hives with Apivar, and repairing near dead hives with brood from less bad hives. Even with that, some hives were not saveable due to not enough good hives to stretch resources from, so my losses are a lot higher than normal. I haven't started the spring round yet so not sure just how bad, but have done a drive by of a few sites and looking like maybe 10% or possibly 15% or so dead. Luckily that will be easily put right, but had I not noticed the issue last autumn there would have been well over 50% loss, possibly much worse. It also says something about some NZ beekeepers, that they have lost as much as 80% of their hives but the cause of death is a mystery. The article says maybe mites, maybe something else. You would think any competent beekeeper could autopsy some hives and if it's mites, be able to diagnose that. And also, that the issue was not noticed until after the hives were dead. [/QUOTE]
