Very dark soil under leaf litter from a park forest (Mahy property) in Landegem, Belgium. Mixed deciduous trees (sample taken 2m from an oak). Collected by Paul De Ley in November 1994.


Secernentea - Rhabditida - Teratocephalina - Teratocephalidae

Culture conditions:

Xenic: "Wet plates": 3-5 drops of E. coli in 4 ml P-buffer (0.05M KH2PO4/K2HPO4 to pH 7.3) on 1% pure agar + 5 µg/ml cholesterol. Keep at 16-18C.

Inoculation procedure:

E. coli are suspended over FRESH plates the day before transfer of nematodes as follows.

Long-term storage:

Freezing has not been attempted.


Freely available on agar.

Males not yet seen. Reproduction is slow (1 egg per female per week? 2 weeks generation time?), but massive numbers can build up in well-sealed plates left alone for three to four months after inoculating abundantly. Specimens are quite sensitive to pH and desiccation; perhaps also to salinity (S-buffer not recommended). Feeding extra E. coli is not necessary for build-up and even results in nematode mortality (pH-shock?).
