Specimens of this interesting group of nematodes were rarely detected in soil samples, and were usually in low numbers, until the development of sugar flotation and centrifugation extraction techniques (Jenkins, 1964). Those techniques maximize recovery of "wide-bodied", slow-moving nematodes.

Feeding:

Ring nematodes feed ectoparasitically on root tips or along more mature roots. The nematodes are migratory unless soil pore space limits their movement. Adult stages of the larger ring nematode adults appear sedentary or stuck within their pore space as they develop to adult size.
