Family TRICHODORIDAE. (Thorne, 1935) Clark, 1961
Type species: Trichodorus primitivus (de Man, 1876) Micol.
Synonym: Dorylaimus primitivus de Man, 1876
Bodies obese with unusually thick cuticle which frequently forms wrinkles
as the nema moves. Females straight when relaxed, males posteriorly
arcuate. Body contents dense, often obscuring details of morphology.
Female tail bluntly rounded with anus terminal or subterminal. Supplements
1-3, mammiform, well-spaced, the anal pair absent. Spear elongate,
slender, slightly arcuate. Spicula slender, arcuate with conspicuous
Interest in Trichodorus species has greatly developed since the
discovery that they transmit certain virus diseases of plants. Typical
injury is known as "stubby root" since roots fail to make additional growth
after the nemas feed on the terminal cells.
