We analyzed nitrogen (N) content in phloem and xylem of 75 northern red oak, Quercus rubra L. (Fagaceae), removed in 2002–2007 from three sites within the Ozark National Forest, Arkansas, to investigate the relationship between vascular tissue N status and wood borer infestation. Populations of native red oak borer, Enaphalodes rufulus (Haldeman) (Coleoptera: Cerambycidae), experienced an outbreak and population crash during the sampling period. Vascular tissue N was not correlated with borer infestation density (exit holes/m−2/bark surface), which suggests variation in N status of vascular tissue was not influenced by or did not influence borer success. Vascular tissue N was greater in trees sampled during winter months than in trees sampled in spring and summer months.

Nous avons analysé le contenu en azote (N) du phloème et du xylème de 75 chênes rouges boréaux, Quercus rubra L. (Fagaceae), prélevés en 2002–2007 dans trois sites de la forêt nationale d'Ozark, Arkansas, afin d'examiner la relation entre le N du tissu vasculaire et l'infestation par les insectes mineurs du bois. Durant la période d'échantillonnage, les populations du grand longicorne du chêne rouge, Enaphalodes rufulus (Haldeman) (Coleoptera : Cerambycidae), un insecte indigène, ont connu une épidémie et un effondrement. Il n'y a pas de corrélation entre le N du tissu vasculaire et la densité de l'infestation des mineuses (nombre de trous de sortie m-2 de surface d'écorce), ce qui laisse croire que le statut en N du tissu vasculaire n'est pas influencé par le succès des mineuses, ni ne l'influence. Les concentrations de N du tissu vasculaire sont plus élevées dans les arbres prélevés durant les mois d'hiver que durant les mois de printemps et d'été.
