Pot experiments were carried out to explore the role of macrochilid mites, Macrocheles muscaedomesticae (Scop.), and staphylinid beetles, Philonthus longicornis Steph. and collembola, Onychiurus sp. singly and in combination on Tylenchulus semipenetrans (Cobb) on sour orange at 29 (+-) 5 degrees C 74 (+-) 5 per cent R.H. in green house. All tested soil mesofauna significantly reduced the population of the nematode. The highest predation rate was achieved by the predator mite, M. muscaedomesticae (Scop.) singly, followed by the combination of soil mite plus collembola. The numbers of soil mesofauna recovered from soil at the end of the experiment were significantly higher in treatments of nematode plus one of each of soil mesofauna than monoinoculation of each
