Mike, use your favourite search engine and look for Discoidal Shift, Cubital Index and Hantel Index. I'll put something together as a .pdf as I did a talk to our local assoc on this topic last year.I would be interested to read a little about it if some one would be kind enough to write a little about this subject.
Typical values taken from literature. Some authors have slightly different numbers for some of the values. The strong pointer to AMM is a negative DS. None of the other species go below zero.What degree of accuracy would you expect or do the marker points vary for each bee which is claimed to be a pure breed.
Wilderness, I’ve visited this Forum to find information about ranges of indexes CI, DS and HI for definition of a breed accessory of bees according to morphological characters of a wing. The more complete information to the question has been presented by you in the message from 04.05.2010 . Would it be asking too much of you to specify a source of this information? Unfortunately, I cannot find such information in Russian sources.Typical values taken from literature. Some authors have slightly different numbers for some of the values.
