摘要：
The extremly biotic and abiotic conditions of a decompositiontip supported the mass population of B.germanica which enabled the development of a new race by means of evolution factors. In experiments under laboratorical and outdoor conditions the cold-tolerance of this new race was studied. Considering the fact, that B. germanica can subsist a middle-European winter under outdoor conditions, we may conclude, that the spreading of this animal will not soon come to an end.
