Abstract

Plant-parasitic nematodes as a prey of the bulb mite Rhizoglyphus echinopus (Acarina, Tyroglyphidae

In feeding experiments the bulb mite,Rhizoglyphus echinophus, was found to feed on the following plant-parasitic nematodes:Aphelenchoides ritzemabosi, Ditylenchus dipsaci, D. destructor, Heterodera avenae, Longidorus elongatus andXiphinema index. Moreover,Fusarium mycelium tobacco leaves and enchytraeids served as a diet. Small nematodes were completely devoured, large species bit into pieces and sucked out. WhiteHeterodera females were ingested with their egg contents, whereas brown cysts were only attacked after a hesitation. It is suggested that the polyphagous mite may constitute a regulator of nematode populations under certain conditions.
