> We have posted on our web site a video of AHB behavior, filmed in TX in August of this year. I hear a lot about AHB, and because of various discussions, have begun to wonder just exactly what an AHB is. People speak and write quite glibly about AHB -- as if we all know exactly what AHB is -- but what exactly is AHB? Does the 'One Drop' rule, formerly applied to humans in the days of apartheid in the US and in SA apply here? Assuming that we can identify an AHB individual, if one drifts into an EHB hive, does that hive then become an AHB hive? If not, then at what level does the hive become AHB? If there is one AHB hive (see above) in a town, then is the town africanized? How about the county in which the town is located? The State? As I understand it, there are a number of genes that are unique to and which distinguish the species of bees that are native to Africa, from the bees that were originally native to Europe. How many of these uniquely African genes must be discovered in a bee for it to be deemed AHB? One? Ten? Is the reverse true? If one distinctly European gene is found, is that bee then EHB. Can a bee be EHB and AHB at the same time? allen http://www.internode.net/honeybee/diary/
