%X A survey was conducted in eight Philippine provinces to identify the major plant parasitic nematode genera associated with upland rice, determine their frequency of occurrence and abundance, and assess their potential as rice parasites. From 190 fields, 1,900 soil and root samples were collected at either pre-seeding or maximum tillering stage. Eleven genera and species of plant parasitic nematodes were found to be associated with upland rice : #Criconemella$, #Helicotylenchus$, #Hemicriconemoides$, #Hemicycliophora$, #Hoplolaimus$, #Meloidogyne$, #Pratylenchus zeae$, #Rotylenchulus reniformis$, #Rotylenchus$, #Tylenchorhynchus$, and #Xiphinema$. In all provinces sruveyed #Criconemella$, #Helicotylenchus$, #P. zeae$, and #Xiphinema$ were present. #P. zeae$ was detected in all the surveyed fields with high population densities (average of 174 per g of root). Low population densities of #Meloidogyne$ wer observed in 35% of the fields. #P. zeae$ was omnipresent and seems to be a component of the Philippine upland rice ecosystem. (Résumé d'auteur)
