Notes

Ultrastructural studies on the cuticle of the second-stage larvae of Meloidogyne hapla, M. javanica, M. incognita, and M. arenaria showed that the cuticle structure in all four species was similar and consisted of six layers divisible into three zones: an outer trilaminate cortex, a two-layered median zone, and a basal striated zone. No association could be established between the structure of the cuticle of L2 M. hapla and the ability of the nematode to survive freezing temperatures significantly better than L2 M. incognita.
