howdy- my mums hive is reputedly KI Ligurian stock- and the bees have been good produces, and are pretty calm- not too much bridge comb etc. Good Bees. I have made a split from that hive. I believe some of the other hives I have also have some degree of Ligurian in them. From what I understand of the pure Ligurian strain on Kangaroo Island- they are noted for a generally good nature- but not as being particularly exceptional producers.
I also now have some yellow Italian bees- they seem very gentle and slower moving than the ligurians. They also bring in large pollen balls. S[peaking to a local beekeeper he is weeding them out of his hives- he likes their temperament but doesn’t see them produce as well. For what it’s worth he seemed to suggest that in his experience- unfortunately- it is the more aggressive bees that produce best.
I read an article about the positive aspects of wild caught bees- and it made some sense to me:
it’s complete with a @Michael_Bush style historical quote- just to re-affirm that there is nothing new under the sun:
“Pick the hive model that is best suited to your locale, populate it with local bees, and the results will speak for themselves,” wrote the famous French apiculturist Georges de Layens in his book The Complete Course in Apiculture, first published in 1892."
