The effect of different substrates on persistence of the facultative slug parasitic nematode Phasmarhabditis hermaphrodita was studied. Four different substrates (sand, leaf compost, organic horticultural substrate and garden soil) were inoculated with P. hemaphrodita strain B1, isolated in central Bohemia, and the persistence of this nematode was observed for 8 months. A new artificial trap was used to isolate nematodes from the substrates. We found that P. hermaphrodita is able to persist in slightly wet sand at least for 5 months. The density of dauer juveniles decreased markedly in sand. The persistence in compost was very low, probably because of large amount of antagonistic organisms. Organic horticultural substrate and garden soil provide the best condition for persistence of P. hermaphrodita. Nematodes are able to persist in these substrates in very high density, for more than 8 months. We demonstrated that P. hermaphrodita preferably persists in organic soil or habitats with a high content of organic matter and readily reacted to the presence of our artificial trap.
