Genus Ditylenchus Filipjev
Genus
Ditylenchus Filipjev
Characteristic
thickening of leaf sheath and stem of rye, accompanied by wavy
leaf growth and general stunting of plants led to the discovery
of a diseased condition, described as 'stock'1. The causal
agent was later found to be a plant parasitic nematode, described under
the generic name, Anguillula dipsaci, infecting teasel,
Dipsacus fullonum. The subsequent years witnessed the description of
the same nematode under different names, Anguilullina dipsaci
var. amsinckiae, Anguillula devastatrix1-4, etc.
Apparently, the confusion arose, by and large, due to the failure of
earlier workers to recognize the existence of physiological races within
conspecific populations of dipsaci and the ability of the
nematode to attack different crops with varied symptomatology and
pathogenicity. Finally, the confusion was partially resolved by Filipjev"
when is proposed the genus Ditylenchus with D. dipsaci as
the type species.
Siddiqi
recognizes 52 valid species under the genus Ditylenchus in
addition to D. dipsaci. Of these, D. dipsaci, D. angustus, D,
destructor and D. myceliophagus are of economic importance.
