           Aorolaimus macbethi (Sher, 1964) Fortuner 1987

Synonyms:

Peltamigratus macbethi Sher, 1964
    Note, Fortuner, 1987 and Baujard et al, 1991, 1994 considered Peltamigratus a junior synonym of Aorolaimus. However, Siddiqi (2000) resurrected Peltamigratu

Morphology and Anatomy:

.

Female:

  • Body spiral to C-shaped, medium sized.  
  • Lip region slightly offset or continuous with body, with or without annules and/or longitudinal striae.  
  • Labial framework and stylet medium sized; stylet knobs flattened to indented anteriorly.  
  • Dorsal esophageal gland opening 3  to 10 µm from stylet base.  
  • Esophageal glands with three nuclei, overlap intestine dorsally and laterally; intestine symmetrically arranged between the subventral glands. 
  • Two genital branches outstretched, equally developed.  
  • Lateral field with four or fewer incisures. 
  • Tail short, rounded.  
  • Phasmids enlarged to scutella erratically situated on body in lateral field, not opposite each other, anterior to anus level; sometimes one scutellum is anterior to vulva level.               

Male:

  • Caudal alae enveloping tail
  • Esophageal structures smaller in males than in females

Soil temperature, soil moisture and host plants have a significant effect on its multiplication rate. 

The nematode is able to enter anhydrobiosis during the dry season and is characterized by a low multiplication rate.
