"Commercial beekeepers aggressively manage for varroa and other diseases, if they didn't the resulting dieoffs would bankrupt them."
Who is speaking nonsense now? Yes, they typically treat for some pests and disease. Those pests and diseases that they generally treat for do not affect native bees. Even when they do treat, they don't have full elimination and are still transmissible. You can see they they still suffer about 50% colony loss like the smaller producers.
"and they sure af don't have more experience with any aspect of hive management than individuals who are successfully managing hundreds if not thousands of hives."
And the people keeping hundreds and thousands of hives for commercial purposes don't have as much time to spend on full inspections. If they know so much about management, then they must be making intentionally poor decisions on how to manage when we talk about things like colony dirft and hive densities, transporting bees all over the place (accelerating any existing spread), and subjecting the bees to active spraying during pollination.
"One management fuckup leading to a single hive collapse absolutely sprays the surrounding 2-3 mile area with diseases and parasites."
Have any data to back that up? You do realize that many of the pests and diseases are routinely present in most hives, right? That's why you need actually concentrations for diagnosing things like nosema. I'd love to see an example of an apiary that has zero varroa too...
"Given annual failure rates all beekeepers are bombing their surroundings with problems, hobby beekeepers just do so for their own personal amusement regardless of which treatment strategy they employ."
This makes zero sense. You claim that all beekeepers are problems. But you only have a problem with small scale producers because they aren't paying their mortgage with it. Interesting distinction which bears no matter on the end result. So it appears this conversation is moot.
"an effort that is vastly complicated by having to geographically isolate breeding operations to try to avoid cross-breeding from unmanaged populations (read backyard hives)."
This is complete nonsense. The breeding programs rely on artificial insemination. You can't control the feral bee populations either, so you must do it in a lab. Most of these government bodies and ag extensions have resources (and requirements) for small scale beekeepers, and even encourage it. Most states have mandatory licensing and inspections too. Most beekeeping associations openly welcome beekeepers of any size operations. It seems you just have an axe to grind.
