Meloidogyne megatyla (Baldwin & Sasser, 1979)

Review general characteristics of the genus Meloidogyne.

Morphology and Anatomy:

Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:

Distribution:

Described from Loblolly pine in Elizabethtown, North Carolina, USA.

Chromosome number 2n=37, 74. The large number, and variability of chromosome number, are typical of species reproducing by obligate mitotic parthenogenesis. (Triantaphyllou and Hirschmann, 1997; Subbotin et al., 2021; Triantaphyllou, 1985).
