Enchytraeids (Oligochaeta, Enchytraeidae) from potting compost purchasable in the Hungarian retail trade

摘要

The high humus and organic material content of potting compost is favourable for detritivores such as enchytraeid worms. An investigation was carried out to clarify which enchytraeid species can be found in this medium. A really low abundance and number of species were found and all of them were well known cosmopolitan species. Consequently, the use of these composts probably cannot cause the increase or invasion of new species, in spite of the worm’s special breeding strategies.
