AHB trade-off?

A Propolis reader in Florida tells me that some beekeepers are looking forward to a little mix of Africanized bee (AHB) genes because they think that might increase resistance against varroa (because the US is running out of effective anti-varroa treatments). Some seem to see the arrival of AHB in Florida as bringing an opportunity for a trade off-between gentility and virility.

I'm not so sure you can get a mild cross with AHB genes -- as I understand it, it's pretty much all or nothing. Good luck Florida!
