Abstract

The present work has been conducted to study the possibility of using entomopathogenic nematodes Heterorhabditis baujardi andHeterorhabditis indica against subterranean termite Psammotermes hypostoma (Desn.), and Anacanthotermes ochraceus (Burm.), under laboratory conditions as a preliminary test for using them under the field conditions. Data showed that, the using of tested pathogenic nematodes H. baujardi and H. indica were effective on the two tested termites. The bioagent H. baujardi strain was highly effective for control of the two tested subterranean termites, but the subterranean termite P. hypostoma was highly susceptible than A. ochraceus. In addition to the highly rate of mortality which started in the 3rd day in all treatments approximately, decreased gradually to reach of stability in 6th or 7th day. Overall, the mortality increased as the nematodes concentrations increased and vice versa.
