Abstract	Inscrits parmi les parasites de quarantaine, les nematodes a kyste, Globodera rostochiensis et Globodera pallida sont presents dans de nombreux bassins de production de pomme de terre ou les degâts sont parfois considerables. La lutte contre ces ravageurs est preventive dans les zones de culture indemnes, condition indispensable a la production de plant de pomme de terre. Des pratiques agronomiques adequates et l’utilisation de varietes resistantes conduisent a la reduction du taux d’infestation des terrains contamines. Dans certaines situations geographiques, le traitement du sol par solarisation peut remplacer efficacement l’emploi de nematicides destines a etre interdits. La resistance genetique represente le moyen de lutte le plus efficace. L’introgression de nouvelles formes de resistance a ete entreprise a partir d’autres especes tubereuses, notamment Solanum vernei. La recente caracterisation moleculaire de nouveaux facteurs genetiques de la resistance chez les especes Solanum spegazzinii et Solanum sparsipilum et l’etude de leur association devraient faire progresser le travail de selection varietale. La combinaison des differents moyens de lutte presentes en fonction des situations devrait aboutir a la mise en pratique d’une veritable lutte integree en culture de pomme de terre de consommation.
