Morphology and Anatomy:

  Nematode is 0.64-0.86 mm long.

Body configuration usually rounded at both ends.

Cuticle tends to swell in water and fixative when nematodes are killed.

Curved onchiostyle with dorsal groove.

Females: Diovarial.
 
Males: Caudal alae absent. Single testis.

Ref. Decraemer, W. 1995.

Feeding:

Ectoparasitic; feeds on epidermal cells at and just behind root tips. Root tips swell (stubby root) or crack and cease to grow (Pitcher and Flegg, 1965).

Nematodes form colonies and swarm in feeding area.

Feeds in cells by repeated thrusting of the odontostyle within a polysaccharide feeding tube.  Cell contents move along the groove on the dorsal side of the odontostyle.

Damage:

May be involved in Docking Disorder in some cases.

Nematode vectors Pea Early Browning Virus (PEBV) and Tobacco Rattle Virus (TRV).

Management:

Docking disorder can be controlled with 1,3-Dichloropropene (1,3-D); Aldicarb also used.
