It has been known for many years that in temperate climates the European honey bee,
Apis mellifera, exists in the form of two distinct populations within the year, short-living summer bees
and long-living winter bees. However, there is only limited knowledge about the basic biochemical
markers of winter and summer populations as yet. Nevertheless, the distinction between these two
kinds of bees is becoming increasingly important as it can help beekeepers to estimate proportion of
long-living bees in hives and therefore in part predict success of overwintering. To identify markers
of winter generations, we employed the continuous long-term monitoring of a single honey bee
colony for almost two years, which included measurements of physiological and immunological
parameters. The results showed that the total concentration of proteins, the level of vitellogenin,
and the antibacterial activity of haemolymph are the best three of all followed parameters that are
related to honey bee longevity and can therefore be used as its markers.
