Nématode du pin : le point en 10 questions-réponses | INRAE FAQ - La détection du nématode du pin pour la première fois en France dans la forêt des Landes en novembre 2025 marque une étape clé. S’il n’était pas encore présent en France, il y avait un grand risque qu’il arrive tôt ou tard sur le territoire. Le point en 10 questions-réponses sur la base de 15 ans de travaux de recherche et de modélisation d’INRAE sur ce ravageur.

Nématode: ce ver microscopique ravageur menace les forêts de pins de cette région de France Le nématode, un ver microscopique, a été détecté pour la première fois en France à Seignosse dans les Landes. Un ver ravageur venu d'Amérique du Nord et qui est très dangereux pour les pins.

"Dans les cas extrêmes, le #nématode du pin va provoquer la mort de l’arbre en quelques semaines”, détaille #MélineSaubin, chercheuse en épidémiologie végétale à #UMR-Biogeco @inrae-france.bsky.social.
