using of the pathogenic nematodes Steinernema scapterisci, against subterranean termite Psammotermes hybostoma (Desn.), under laboratory conditions, showed that, it was more effective at concentration 4000, 2000 and 1000 IJs/ml = 10 IJs/ insect. In addition the highest rate of mortalities were in the 4th day in all treatments, then decreased to reach to minimum in 7th day. The nymphs were more susceptible and died faster than adult workers and soldiers. The statistical analysis showed significant differences among treatments. The present work has been conducted to test of termite traps contained entomopathogenic nematode Steinernema scapterisci, against subterranean termite Psammotermes hybostoma (Desn.), under field conditions. Data showed that, using the tested pathogenic nematodes treated once/year were effective throughout the 3rd months after treatment (Jan., Feb., and March), when treatment with the entomopathogenic nematode was replicated 4 times/year, the efficiency was not significantly higher.
