I think beekeeping, and most ag, is much more localized than it used to be, which is kind of odd since so much is now commercialized.
Wax moths are a huge problem for me, partly because they don't go dormant here. The Bt didn't kill the moths, but the bees don't like it, and won't word frames sprayed with it. I have one hive that is obviously part AHB, and even they get moths, so size/strength/attitude are not the only factors.
No varrora problems for me, but I know that makes me odd (er).
SHB also a problem here, but again, no dormant season. AJs traps and vinegar work well.
CCD, EFB, AFB, Nosema, not a problem for me.
Fire ants BIG problem for me, and they are not like other ants, so the helpful advice from those who've never dealt with them is just irritating.
Weather extremes here in TX have also been a factor -- 2007, wettest year on record. 2008 below average moisture. 2009-2011 Record drought across the state. 2012, better than last year, but still behind.
If you read most of the major books, they write as if all conditions, problems and solutions are the same everywhere, and I'd like to see more forum members recognize that it just ain't so anymore. And my different experience does not automatically mean that I am wrong. But that's another thread.
Keep up the good work, Solomon. If we keep swimming upstream, we'll eventually make progress, right?
