Slugs and slug- parasitic nematodes
According to Rae et al. (2008), slug parasitic nematode Phasmarhabditis hermaphrodita was not effective against the pulmonate Slug species, Limax pseudoflavus because nematode infective juveniles were encapsulated and killed in the slug shells due to the immune response of slug, Limax pseudoflavus.
