Abstract Fadenwurm. Die Zellwand der Rhizodermiszelle wird mit schnellen, unregelmäßigen Stößen des Mundstachels durchbohrt. Speichelabgabe; Zytoplasmagranula werden vor dem Stachel abgebaut und durch regelmäßige, schnelle Pulsationen der Pumpe im Mittelbulbus des Ösophagus aufgesaugt.
A complete feeding process of Tylenchorhynchus dubius on seedling roots of rapeseed consists of five phases: probing, puncturing of the cell wall, salivation, ingestion and departure from the feeding site. The film shows characteristic details of the phases that follow probing. The wall of epidermal cells and root hairs is punctured with rapid and irregular stylet thrusts. During salivation salivary granules flow continuously from the site of synthesis, in front of the dorsal gland-cell nucleus, through the gland duct towards the gland reservoir. Food is ingested by steady and very rapid pulsations of the metacorporeal pump. Granular constituents of the cytoplasm are not drawn into the stylet.
