Review general characteristics of the genus Meloidogyne.

Morphology and Anatomy:

This species is reported to have only 7 chromosomes, similar to M. spartinae, rather than the n=13-19 of most root-knot nematode species. The chromosomes of M. kikuyensis are larger than those of most other Meloidogyne species  (Eisenback and Viera, 2020).

Female:

Distribution:

Reported fro, kikuyu grass (Pennisetum clandestinum) in Kenya and sugarcane (Saccharum officinarum) in South Africa (Eisenback and Viera, 2020).

Damage:

Causes small nodule-like galls on roots. Giant cells seem to be formed by disoolution of cell walls, as occurs with cyst nematodes, rather than by hypertrophy and nuclear division without cell divison.

The vascular tissues supplying the giant cells are at right angles to the vascular cylinder of the main root.
