Enoplea Triplonchida Diphtherophorina Diphtherophoidea Trichodoridae Trichodorinae Trichodorus similis (Seinhorst, 1963) Hunt, 1993
Females: Diovarial.
Males: Caudal alae absent. Single testis.
Body configuration usually rounded at both ends.
Cuticle tends to swell in water and fixative when nematodes are killed.
Curved onchiostyle with dorsal groove.
Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:
Temperate regions of Europe.
Nematode prefers light, sandy loam.
D-rated pests in California.
Ectoparasite on epidermal cells and root hairs; aggregates just behind root tip.
Feeding tube forms within stoma and remains attached to puncture hole.
Feeds in cells at the root tip by repeated thrusting of the odontostyle within a polysaccharide feeding tube. Cell contents move along the groove on the dorsal side of the odontostyle.
Potato, walnut, apple, pear, barley, and carrots.
Ecophysiological Parameters:
Feeding causes root growth to stop. Lateral roots attacked, giving rise to "stubby-root" symptom. Nematode also vectors Tobacco Rattle Virus.
Control of Docking Disorder achieved with 1,3-Dichloropropene (1,3-D) (65-136 liters/hectare, 6-12 gpa).
