What  method do you suggest?

First signs if you suspect AHB other than from aggressive behavior.

1. Queens which have obviously been laying leave brood and try to hide.

2. Bees take flight (nursebees also) leaving brood.

3.bees running on frames.
At times the bees bunch up andfall off thebrood frame

The above are not traits normally seen in European bees.

Was interesting behavior to observe the first time.

When the queen is AHB and her and a small group have moved into a hive and replaced 
the old queen 1 might be the first observation.

Forget color and queen size.  Marked or clipped queens might help new beekeepers

Hives with rising AHB genetics can be worked with correct smoke use and Not mashing bees.

If list members live in areas of documented AHB you need to pay attention to the above
And mark the above for requeening or depopulation.

Every hive has a bad day once in awhile so when you  observe the above on back to back inspections
I Would act for sure.

Once extreme aggressive is seen your work is cut out for you.



I share hoping will help as wing morf and sending off for testing  has little practical application.
