Meloidogynidae - (root-knot nematodes)
The family is related to the Heteroderidae and has been previously treated as a subfamily of that group. The members of the Meloidogynidae differ from those of the Heteroderidae by:
- the feeding site is a multinucleate giant cell (not a syncytium where root cells fuse through the dissolving cell walls),
- females are not transformed into a cyst, but lay egg masses in a protective gelatinous matrix,
- parthenogenic reproduction is common,
- species have a wide host range.
For details on the biology see the genus Meloidogyne.
