Identification of honey bee subspecies
• Identification based on
DNA is expensive
• Morphological
differences between subspecies are small
• Identification requires
multiple measurements
• The measurements are
time consuming

Honey bee queen breeding in Poland
Gerula, Tofilski et al. (2009) Journal of Apicultural Science
• The automatic wing
measurements are
used by Polish
queen breeders
• The new method is
faster and more
precise

Feral (unmanaged) colonies were found in avenues of trees
• 45 nests
• 0.3% of all trees
• 1.3% of hollow trees
• density of feral nests
0.10 nests/km2

Rural avenues should be protected
• habitat for bees and
other organisms
• provide pollinators for surrounding crops
• landscape protection

Conclusions
• Identification of honey bee subspecies
is essential for their conservation
• Measurements of wing venation is fast
accurate identification method
• Feral colonies of native A. m. mellifera
are still present in Europe
• Avenues of trees should be protected
as a potential nesting site for bees
