Abstract

During a preliminary survey of plant parasitic nematodes in Iowa, 55 species, mostly in the Tylenchoidea, were identified. Except for Longidorus, Xiphinema, and Trichodorus, the Dorylaimoidea were not considered. Most samples were taken in forage legume fields and woodlands. The seven genera encountered most frequently were the following, as expressed in percentage of total samples (1,308): Tylenchus (56), Helicotylenchus (40), Xiphinema (36), Aphelenchus (31), Tylenchorhynchus (20), Paratylenchus (14), and Pratylenchus (13). Helicotylenchus microlobus and Xiphinema americanum were among the most common and widespread plant parasitic nematodes found. While H. microlobus occurred most frequently in cultivated fields, H. platyurus was mainly a woodland inhabitant. Although processing procedures were not directed toward recovery of root knot and cyst nematodes, evidence indicates that Meloidogyne hapla, Heterodera trifolii, and H. weissi are common in Iowa.
