The American Beekeeping Federation has several members who are Canadian beekeepers. They come down to our annual convention every year. Most of the pests in that risk assessment, I think, are already in Canada. That is my understanding anyway.
Things like varroa resistance are very minor. If the tropilaelaps mite—I can't stress that enough—comes to North America, we are in big trouble. I think that's the most important thing to look at right now.
Dr. Frank Rinkevich at the USDA lab in Baton Rouge has some great studies on amitraz resistance. I'm sure you can look those up online. Some of those studies.... They're all public information. I urge you to take a look at those, because there is amitraz resistance. I think it's everywhere.
