In New Zealand the European invasive slug Deroceras reticulatum is a pest in home gardens horticulture pastoral and arable agriculture At present there are no biological control options available in New Zealand unlike Europe where the nematode parasite Phasmarhabditis hermaphrodita is sold in several countries under the trade name Nemaslug This paper describes the finding of a nematode parasitising D reticulatum in New Zealand that was identified by morphological and molecular (18S rDNA sequencing) methods as P hermaphrodita The nematode was reared on slug cadavers and shown to infect and kill fieldcollected D reticulatum In mesocosm experiments with clover the New Zealand P hermaphrodita applied at the recommended commercial rate substantially increased plant density even under high slug pressure
