Ecology of the mycophagous nematodeAphelenchus avenae in wheat-field and pine-forest soils

  • G. E. Walker


The soils of a wheat-field and pine-forest had different mycofloras and supported different populations ofAphelenchus avenae, a mycophagous nematode. The abundance ofA. avenae was correlated with the composition of the mycoflora in these soils; the greater abundance ofA. avenae in wheat-field soil being associated with a more diverse mycoflora.
