Trichodorus is a genus of terrestrial root feeding (stubby-root) nematodes in the Trichodoridae family (trichorids), being one of five genera.Order Triplochida: Paratrichodorus Nemaplex: Nematode-Plant Expert Information System. University of California, Davis. Version October 9, 2012. 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,SIDDIQI M.R. (1974). Systematics of the genus Trichodorus Cobb, 1913 (Nematoda: Dorylaimida), with descriptions of three new species. Nematologica, 19 : 259-278. Trichodorus and Paratrichodorus.
The genus, which is the largest in the family consists of 69 species. The females are didelphic (two genital tracts), and are distributed worldwide.
Plant pathology Trichorids became of interest in 1951.CHRISTIE, J. R. & PERRY, V. G. (1951). Removing nematodes from soil. Proc. helm. Soc. Wasb. 18: 106-108. At that time Trichodorus christie (=Paratrichodorus minor) was recognised as a pest of crops in Florida. Species Trichodorus contains the following species:
