The interaction of the wood driller (Pantophthalmus roseni) and the red oak (Quercus germana) in the cloud forests of the Biosphere Reserve El Cielo at Gómez Farías, Tamaulipas, Mexico was studied. Forty mature individuals of Quercus germana were selected for comparison (20 healthy trees, 20 with severe damage, i.e. ³ 15 wood perforations caused by P. roseni). Healthy and damaged trees were measured for levels of herbivory, percentage of foliar nitrogen, total phenols concentration and acorn production. Herbivory was significantly greater (P< 0.05) in healthy than in damaged oaks. The healthy group had 1.5 times more leaf herbivory than the damaged group. Foliar nitrogen content in Q. germana (5.3%) showed significant variations in relat...
