[QUOTE="John B, post: 2980, member: 207"] If the current situation is caused by PPB then it is the largest outbreak of PPB the country has ever seen and amongst many beekeepers that have never had a problem with PPB before. If synthetic pyrethroids are still working for you then that is great but given the number of hives that are moved around the countryside they won't be working for long. I had hives two years ago with varoa that were totally resistant to Bayvarol . I did a properly conducted scientific tests on these hives using brand-new strips from a different batch and the correct number of strips with careful monitoring and alcohol washes. It was no surprise to me that the epicentre was near another beekeeper that hadn't used anything but bayvarol for 10 years (it works fine why should I change). It's no surprise to me that these resistant mites have spread. It did surprise me at the time that nobody seemed to believe me or take what I was saying seriously. It no longer surprises me that apart from those that have had their faces rubbed in it ,I'm still not believed. [/QUOTE]
