Abstract

Twenty-eight species of plant-parasitic nematodes were identified from the rhizosphere of 467 maize samples obtained from 72 counties. Helicotylenchus pseudorobustus, Pratylenchus spp., and Xiphinema americanum were found most frequently. The mean number of Pratylenchus spp. in roots from 339 samples was 3,413/gram of dry roots, with a maximum of more than 84,000. Longidorus breviannlatus and Quinisulcius acutus had the most marked distribution patterns, the former being found mainly in eastern Iowa and the latter mainly in the western part of the state. The least diverse (H¹) plant-parasitic nematode communities were in the sand and clay-loam soils.
