Some observations on the morphology and protein profiles of the slug-parasitic nematodes Phasmarhabditis hermaphrodita and P. neopapillosa (Nematoda: Rhabditidae)

Abstract

AbstractThe slug parasitic nematodes Phasmarhabditis hermaphrodita and P. neopapillosa are described and figured including observations with the scanning electron microscope. P. hermaphrodita is a protandrous hermaphrodite and males were not found in most of the cultures derived from slugs. Populations in which males were common were identified as P. neopapillosa. Apart from their mode of reproduction, these two species are morphologically identical. Protein electrophoresis using the Pharmacia PhastSystem or a cellulose acetate system stained for phosphoglucose isomerase resulted in very different patterns for the two species, indicating that their different specific identities are warranted. Quelques observations sur la morphologie et les profils proteiniques des nematodes parasites de limaces Phasmarhabditis hermaphrodita et P. neopapillosa (Nematoda: Rhabditida) - Les nematodes parasites de limaces Phasmarhabditis hermaphrodita et P. neopapillosa sont decrits et illustres notamment en microscopie electronique a balayage. L'electrophorese des proteines a l'aide du Pharmacia PhastSystem ou d'une procedure utilisant un systeme a l'acetate de cellulose colorant la phosphoglucose isomerase definit des profils tres differents chez les deux especes, confirmant ainsi a chacune leur statut d'espece valide.
