Categorized as predators and omnivores (Yeates et al., 1993).

Bilgrami (1993) reported the predatory behavior of A. nivalis on prey of different trophic categories, including frequency of encounters resulting in attack, attacks resulting in wounding, feeding after wounding, prey left unconsumed and duration of feeding on individual prey.  Migratory juveniles of sedentary endoparasitic nematodes were highly susceptible but other predator species were quite resistant to predation.  Ectoparasitic and facultatively endoparasiticspecies including Hoplolaimus indicus, Scutellonema sp., Hemicriconemoides mangiferae, Hemicycliophora dhirendri were provided physical resistance to attack by features such ass such as thick body cuticle, thick striations and cuticular sheaths. Other nematodes exhibited behavioral resistance to predation in the form of rapid undulatory activity and evasive action, e.g. Mononchus aquaticus and Rhabditis sp.
