Hi Waldemar > I assume you are referring to the AMM bee that's kept by many in > the UK. I was not specifically referring to AMM, but to hardier more energetic bees than Italian types. AMM does fit the long hours and long lived situation, but you will not find much evidence of AMM in US, as many of the original genes of AMM have been eliminated... Only 3% of genes in US stocks can be attributed to AMM, see... http://www.beesource.com/pov/ahb/jee1995.htm Regards & Best 73s, Dave Cushman, G8MZY http://website.lineone.net/~dave.cushman or http://www.dave-cushman.net Short FallBack M/c, Build 6.02/3.1 (stable) -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
