Trichodorus

Trichodorus is a genus of terrestrial root feeding (stubby-root) nematodes in the Trichodoridae family (trichorids), being one of five genera. They are economically important plant parasites and virus vectors.

Taxonomy
As originally described by Cobb in 1913, Trichodorus was the only genus in its family. However, in 1974 the genus was split into two genera in 1974 by Siddiqi, Trichodorus and Paratrichodorus.

The genus, which is the largest in the family consists of 54 species. The females are didelphic (two genital tracts), and are distributed worldwide.

Plant pathology
Trichorids became of interest in 1951. At that time Trichodorus christie (=Paratrichodorus minor) was recognised as a pest of crops in Florida.
