Small family with four genera recognized as of 1996:
Etymology - from the Greek trichos (a hair) and dory (a spear).
Trichodorus and Paratrichodorus occur worldwide, Monotrichodorus and Allotrichodorus only reported from South and Central America as of 1996.
Wide host range, stunt roots, transmit Tobacco rattle Virus, Pea early-browning Virus and Pepper Ringspot Virus.
At root tip.
Stubby root nematodes are characterized by a curved onchiostyle which is not hollow. Ingested cell contents are channeled along a groove on the dorsal, outer, surface of the curve. A polysaccharide feeding tube forms around the spear as it penetrates the cell wall; the feeding tube may aid in channeling cell contents along the spear.
Wide host range.
Root elongation ceases.
The common name of these nematode genera, stubby root nematodes, reflects the root tip feeding habit, which in many plants, results in termination of root elongation. Like nematodes in the Dorylaimida, stubby root nematodes are directly damage plants through their feeding, but are also capable of transmitting plant viruses.
