Heterorhabditis bacteriophora (Poinar, 1976) - nematode
Photorhabdus luminescens spp. luminescens - and
Photorhabdus luminescens spp. laumondii - symbiotic bacteria

The nematodes is effective against root weevils and scarabs and is commercially available. The species has been described as cruiser and is considered to be especially effective against slow moving soil insects. It contains the mutualistic and pathogenic bacterium Photorhabdus luminescens (syn. Xenorhabdus luminescens).

P. luminescens can be grown on artificial media and is by itself of interest as an entomopathogen. It produces a number of toxins which can kill insects after oral feeding.
