Abstract

Pratylenchus hexincisus is a migratory endoparasitic nematode commonly attacking corn and soybeans in Iowa, but infrequently found in native Iowa prairies. This nematode was inoculated on corn (Zea mays) and three perennial prairie species (Helianthus grosseserratus, Sorghastrum nutans, and Sporobolus asper), and the nematode numbers were observed monthly for 6 months. An increase in nematode numbers was observed on corn. Decreases, but never extinction, in nematode numbers were observed on the three prairie species. It is concluded that these prairie species are inefficient hosts and may be contributing factors for the infrequent occurrence of P. hexincisus in Iowa prairies.
