Photorhabdus is a genus of bioluminescent, gram-negative bacilli which lives symbiotically within entomopathogenic nematodes, hence the name photo (which means light producing) and rhabdus (rod shape). Photorhabdus is known to be pathogenic to a wide range of insects and has been used as biopesticide in agriculture.

==Life cycle== Photorhabdus species facilitate the reproduction of entomopathogenic nematodes by infecting and killing susceptible insect larvae. Entomopathogenic nematodes are normally found in soil. Nematodes infect larval hosts by piercing the larval cuticle. When the nematode enters an insect larvae, Photorhabdus species are released by the nematodes and will produce a range of toxins, killing the host within 48 hours. Photorhabdus species feed on the cadaver of the insect and the process converts the cadaver into a nutrient source for the nematode. Mature nematodes leave the depleted body of the insect and search for new hosts to infect. 200px|thumb |alt=| Entomopathogenic nematodes emerging from a wax moth cadaver
