<br/><br/> A pot experiment was carried out to evaluated the ability of entomopathogenic nematodes (EPNS), Steinernema sp, Steinernema carpocapsae, Heterorhabditis bacteriophora (B20) and Heterorhabditis bacteriophora (HP88) as biological control agents of the citrus nematode Tylenchulus semipenetrans, plant-parasitic nematodes (PPNS) infecting sour-orange plants in the greenhouse. Entomopathogenic nematodes as added at three doses (2000, 4000, 8000 infective juveniles) to sour- orange plants pots one week before adding the inoculations of citrus nematode, T. semipenetrans (3000 juveniles/pot). The highest reduction of T. semipenetrans juveniles in the soil and egg-masses were recorded at the treatment of adding 8000 IJS of H. bacteriophora (HP88). Steinernema sp. This research may contribute in the novel direction of using EPNS as biological agents of PPNS.
