Abstract

Three Xenorhabdus nematophilus subspecies influenced Steinernema glaseri growth profiles and growth rates, but this was not necessarily because of different bacterial growth rates. Virulence of dauer nematodes in larval Galleria mellonella varied with the number of dauers retaining bacteria and the bacterial subspecies. Virulence was least for dauers grown on X. nematophilus subsp, bovienii because of the lack of retained bacteria. Virulence was subsequently restored by culturing these nematodes on X. nematophilus subsp, poinari. Key words: Steinernema glaseri, Xenorhabdus nematophilus, Galleria mellonella, dauer juveniles, bacterial retention, virulence.
