Résumé
[EN] Xylotrechus arvicola represents a significant insect pest impacting Vitis vinifera within the
principal wine-producing territories of the Iberian Peninsula. The larvae of this species bore into
grapevine wood, resulting in significant structural and biomechanical deterioration to the plant.
Compressive and flexural tests were conducted to assess the mechanical properties of wood affected
by X. arvicola. Compressive and flexural strength exhibited a decline with the escalation of the
Total Damaged Surface Area (TDSA) of the samples, ranging from 0.31% to 0.73% in trunks and
from 0.04 to 0.76% in branches, irrespective of the wood moisture content (fresh and dry). The
most significant reduction in resistance occurred in affected dry trunks and branches. Notably, the
deflection at break for dry samples was lower compared to fresh samples (65.00 and 97.85 mm,
respectively). Moreover, the deflection at break for affected fresh samples (164.37 mm) significantly
surpassed that of unaffected fresh samples (72.58 mm) and affected dry samples (37.50 mm). It
is noteworthy that a higher percentage of TDSA coincided with diminished wood resistance. The
percentage of fungal growth symptoms observed in affected wood samples was 66.66% for dry trunks,
75.00% for fresh branches, and 60.00% for dry branches. The damage inflicted by larvae facilitated the
spread of grapevine diseases via emergence of holes created by insects upon exiting the wood and
through the larval galleries connected to them. This damage also altered the mechanical properties of
grapevine plants, with fresh branches exhibiting the most pronounced effects
