Trichodorus is a genus of terrestrial root feeding (stubby-root) nematodes in the Trichodoridae family (trichorids), being one of five genera.^[2] They are economically important plant parasites and virus vectors.^[3]

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,^[4] Trichodorus and Paratrichodorus.

The genus, which is the largest in the family consists of 54 species.^[5] The females are didelphic (two genital tracts), and are distributed worldwide.

Plant pathology

Trichorids became of interest in 1951.^[6] At that time Trichodorus christie (=Paratrichodorus minor) was recognised as a pest of crops in Florida.^[7]
