The only way that they have survived to this day is by being naturally selected for by the harsh laws of nature. In many ways I believe that modern beekeeping with its severe emphasis on production and capital has done Apis a bad turn. We have bred the honeybee for specific traits and left them vulnerable to diseases. This is a phenomenon that is commonly seen with agriculture and livestock breeding.>> I'm sure this is correct; the common pattern with diseases is that they are highly virulent at first; the most susceptible stocks are wiped out, along with the most virulent strains (which annihilate their hosts and thus fail to survive), and the end result is equilibrium. A perfect example would be Myxamotosis in British rabbits; when it was introduced (1950's?) it wiped out the vast majority of the population. We now have equilibrium, with a healthy rabbit stock, and regular outbreaks of myxy. If the bees are allowed to adapt, I'm sure the same will happen in the case of mites. What hard data is there for the survival of bees with TM over the years? Regards, Robert Brenchley [log in to unmask]
