Cells of the bacterial symbiont Xenorhabdus nematophila from the entomopathogenic nematode, Steinernema carpocapsae entered the pupae of Plutella xylostella after 15 minutes treatment with suspensions containing the bacterial cells. Secretions of Xenorhabdus nematophila, in either broth or water, were found lethal to the pupae of P. xylostella when applied in moist sand. The bacterial symbiont Xenorhabdus nematophila was found lethal to the pupae of greater wax moth (Galleria mellonella), beet armyworm (Spodoptera exigua), diamondback moth (Plutella xylostella) and black vine weevil (Otiorhynchus sulcatus) in the absence of the nematode vector and the cells of X. nematophila entered the haemocoele of the pupae.
