Through my reading of the literature on the classification of honey bees in the world, I did not find an internationally accredited taxonomic study on the Iraqi bee races.
I think it is because no scientists / funding organizations were not interessed by this issue. So I think that the question is not "why". I think you should ask: is it worth for somebody to study the races of honey bees present in Irak?
and my own response is a big "YEEEEEEESSSSSSSSSS"!!!!!
Why? 1- because my experience in beekeeping in some African countries taught me that the "racial" differences between regions in the same country have a high influence on the hive management and should be learnt before developping a program of rural development based on beekeeping. 2- as citizen of a Middle East country (Israel) it should be interresting to me that a colleague from a neighbooring country could find a/some good unknown races of honey bees that are adapted to the semi-desertic environments of the region, different than the A. mellifera syriaca for exemple, which is "too defensive" in her behaviour. 3- as a researcher in honey bees/beekeeping, I think we have to try to know the maximum about our honey bee characteristics and diferences to "play" with them, and be able, in particular, to use good sides to resulve some problems - for example about their health
