> There has been great interest in breeding for ‘locally adapted stocks’ which survive winter conditions in a particular region. Here, we evaluate the impact of geographic origin of stock on colony weight, population size, and overwintering survival. Comparing four different U.S. honey bee stocks (two bred in southern and two bred in northern regions) under standard beekeeping practices in three different apiary locations in central Pennsylvania, we examined possible adaptation of these stocks to temperate conditions ... We found that stock or region of origin was not correlated with weight, population size, or overwintering success ... However, colony size and weight in fall, likely correlated with floral resources around the apiary, had the largest effect on the likelihood of colonies to successfully overwinter.
