The predation abilities of Prionchulus punctatus, Mononchus aquaticus, Butlerius degrissei, Labronema vulvapapillatum and Neoactinolaimus duplicidentatus on a range of prey species were observed in laboratory cultures. Only Panagrellus redivivus was easily wounded by all the predators; other free-living and plant ectoparasitic species were relatively resistant to predation. Migratory stages of plant endoparasites were moderately susceptible to attack. These results are discussed in terms of the predators' role as natural control agents of plant parasitic nematodes.
