In: Egyptian Journal of Agricultural Research 2005.v.83(2),SISummary: Efficacy of three entomopathognic nematode strains, viz., Steinernema carpocapsae (Scali); S. riobrave (Sr.) and Heterorhabditis sp. (Hbs1)) in reducing population of Hellula undalis F. and Artogia rapae L. (Lepidoptera: Pyralidae) on cabbage seedlings under field and greenhouse conditions was evaluated. The result showed that the treatments were more effective under greenhouse conditions than under field conditions in case of H. undalis. The reduction was 96.2, 94.3 and 79.4% for Sr., Hbsl and Sc., respectively. Whereas in the field the results were 81.5, 78.3 and 73.8 % for Sc., Sr. and Hbs1, respectively. On the other hand no significant differences were found between field and greenhouse results in case of A. rapae. H. undalis was more susceptible to the three tested nematode strains, than A. rapae.
