A survey on the occurrence of plant parasitic nematodes of the yellow yam (Dioscorea cayennensis) in six municipalities of the Rainforest Zone (Zona da Mata) in the State of Pernambuco: Aldeia, Paudalho, Vicencia, Itapissuma, Goiana e Condado was carried out. The results indicated the presence of the species Pratylenchus coffeae, Meloidogyne sp., Rotylenchulus reniformis, Helicotylenchus diltystera and Criconemella ornata in all sampled areas, except for H. dihystera in Itapissuma. The yam nematode Scittellonema bradys, the etiologic agent of dry rot in yam, was not found, confirming Moura and collaborators' data published in 2001 on the progressive replacement of this nematode by P. coffeae, which causes similar symptoms in yellow yam tubers. This nematode can Currently be found in almost all yam producing areas in Northeastern Brazil.
