    Predator on other nematodes (Yeates et al., 1993; Bilgrami and Jairajpuri, 1989).

    Bilgrami and Jairajpuri (1989) divided mechanisms of predation and food intake are divided into five phases: 1. encounter with the prey, 2. attack reaction, 3. attack, 4. saliva release / extracorporeal digestion and 5. food intake. Most phases were similar in M. fortidens and M. longicaudatus.

     M. fortidens attacked more frequently and needed less time to eat the prey than M. longicaudatus. The latter tested his prey more gently and for a long time, while in M. fortidens the test was more severe and shorter. The rate of predation was the same for both male and female predators and was affected by the number of prey animals available, the hunger status of the predators and the temperature. The highest prey catch occurred in a population of 200 prey animals at 25-30 ° C with predators that had starved for 12 days. Bacterivores Acrobeloides sp., Cephalobus sp., Panagrellus redivivus and the J2 stages of the plant parasites Meloidogyne incognita and Anguina tritici were the most preferred prey of the two predators. As observed for Apocelaimellus nivalis, plolaimus indicus and Hemicriconemoides mangiferae, perhaps protected by cuticle thickness and or cuticular sheaths were not eaten (Bilgrami, 1983).
