  • Title: [Effect of the soil contamination with a potato cyst-forming nematode on the community structure of soil-inhabiting nematodes].
    Author: Gruzdeva LI, Suzhchuk AA.
    Journal: Parazitologiia; 2008; 42(6):510-6. PubMed ID: 19198175.
    Abstract:
    Nematode community structure of the potato fields with different infection levels of potato cyst-forming nematode (PCN) such as 10, 30 and 214 cysts per 100 g of soil has been investigated. The influence of specialized parasite on nematode fauna and dominance character of different ecological-trophic groups were described. Parasitic nematode genera in natural meadow biocenosis and agrocenoses without PCN are Paratylenchus, Tylenchorhynchus, and Helicotylenchus. It is established, that Paratylenchus nanus was the prevalent species among plant parasites at low infection level. Larvae of Globodera prevailed in the soil with middle and high infection levels and substituted individuals of other genera of parasitic nematodes. The fact of increase in number of hyphal-feeding nematode Aphelenchus avenae was revealed.
