Morphology and Anatomy:

.

 See characteristics of the genus Meloidoderita

AFemale:

  • Body shape subspherical to spherical
  • Cuticle without spines or longitudinal lines.
  • Irregularly-shaped neck probably due to constrictions of host cells
  • Lip region cap-like, flattened.
  • Stylet slender, sometimes benmt, knobs well-defined.
  • Meian bulb large
  • Basal bulb large, rounded.
  • Vulva terminal with rounded dorsal and ventral lips giving the appearance of a vulval cone.
  • Uterus swollen with eggs, occupying more than half of the body. Some eggs are deposited into a gelationous egg sac that completely surrounds female body, other eggs are retained..
  • Uterus wall thickens and forms a cystoid body within the cuticle of the dead female and protects retained eggs

 

      Ref: Van den Berg and Spaull, 1982.

 

Male: 

  • Very slender
  • No stylet
  • Esophageal region degenerate
  • Four indistinct lines in lateral field
  • Testis well developed
  • No bursa

Economic Importance:

Feeding:

 Sedentary semi-endoparasite with only the neck regiorn embedded in root tissue. Neck region irregularly shaped due to constrainin effects of host cells and cell walls.

Females distributed along the roots or in clusters of 2 or 3.

Males apparently do not feed; lack stylets and functional esophagus. Juveniles have a robust, well-developed stylet.

Egg sacs surrounding females may also contain one to four males, each with a well-developed testis, suggesting the possibility of sexual reproduction.
