| description | 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 relation to the seasons (rainy season = 5.2% and dry season = 5.1%) and between damage groups, as well as in the interaction of season and group. The damaged trees group had 1.2 and 1.5 times more phenols concentration than the healthy group during the rainy season and dry season, respectively. Acorn production was significant greater (P< 0.05) for the damaged group than the healthy group. The importance of these results in understanding and managing this insect as a forest pest, as well as, the effects of herbivory in the cloud forests are discussed. |

La interacción del barreno del encino (Pantophthalmus roseni) y el encino rojo (Quercus germana) fue estudiada en el bosque mesófilo de montaña de la Reserva de la Biosfera El Cielo, Tamaulipas, México. Se seleccionaron cuarenta individuos maduros de Q. germana para comparación (20 árboles sanos y 20 árboles con daño severo, > 15 perforaciones en el fuste causadas por P. roseni). En árboles sanos y dañados fueron medidos los niveles de herbivoría, el porcentaje de nitrógeno foliar, la concentración total de fenoles y la producción de bellotas. La herbivoría fue significativamente mayor (P< 0.05) en los encinos sanos que en los dañados. El grupo de encinos sanos tuvo 1.5 veces más herbivoría foliar que el grupo de los dañados. El contenido de nitrógeno foliar en Q. germana (5.3%) mostró variaciones significativas en relación a las estaciones (estación lluviosa = 5.2% y estación seca = 5.1%) y entre grupos de daño, como también en la interacción de estación y grupo. El grupo de árboles dañados tuvo 1.2 y 1.5 veces más concentración de fenoles que el grupo de los sanos durante la estación lluviosa y la estación seca, respectivamente. La producción de bellotas fue significativamente más grande (P< 0.05) para el grupo de árboles dañados que para el grupo de los sanos. La importancia de estos resultados en la comprensión y el manejo de este insecto como una plaga forestal, así como los efectos de la herbivoría en el bosque mesófilo de montaña son discutidos.
