If I understand Dee correctly, what she is saying in essence is that cell  
size is not a reliable rapid test for AHB in areas where the size has been  
reduced by the beekeeper for unconnected reasons.
 
Wings venation is taken as being a good pointer towards distinguishing  
between the various races of European honeybees and they are listed in Ruttner's  
book.  Can the same test be applied as a reliable indicator of AHB? This  would 
not be as accurate as a DNA test but could be done by the amateur  beekeeper 
with little trouble, given some instruction.  Are the wing vein  indices for 
AHB listed anywhere?
