Meloidogyne kikuyensis De Grisse, 1961

Review general characteristics of the genus Meloidogyne.

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:

Body round to sub-spherical
Perineal with high square dorsal arch.

Distribution:

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

Chromosome number n=7. Reproduction by amphimixis (Triantaphyllou, 1985; Eisenback and Viera, 2020; Subbotin et al., 2021).

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.
