| description | Damage caused to Eysenhardtia polystachya by the bark beetle Chaetophloeus mexicanus (Coleoptera: Curculionidae; Scolytinae) was investigated as was host response to infestation. A general wood and bark anatomy of E. polystachya is given. Larvae and adults of C. mexicanus penetrate, settle down and consume noncollapsed phloem cells, vascular cambium, and secondary xylem. As a response to damage, there is a deposition of dark-staining contents (tannins) in the cells that limit the cavern. At xylem, this deposition occurs in the lumen of some vessels and fibers, but tissue proliferation did not appear. In the noncollapsed phloem a greater proportion of thick-walled cells and darkstaining contents were observed. However, above of this region, the differentiation of some parenchyma phloematic cells starts. Damage is mainly centered in the noncollapsed phloem, vascular cambium, and the just differentiated xylem cells clearly interrupting water and sap movement. |

Se describe el daño causado a la planta huésped (Eysenhardtia polystachya) por el descortezador Chaetophloeus mexicanus (Coleoptera: Curculionidae; Scolytinae) y la respuesta de la planta huésped a la infestación. Además se presenta una descripción de la corteza y madera de E. polystachya. Larvas y adultos de C. mexicanus penetran, se establecen y consumen células de la corteza, cámbium vascular y madera. Como respuesta al daño, hay acumulación de taninos en las células que limitan la caverna. A nivel de xilema secundario esta deposición se da en los lúmenes de algunos vasos y fibras, pero no se presentó proliferación de tejido. En el floema no colapsado se observó una mayor proporción de células con paredes engrosadas y de taninos. Sin embargo, por arriba de esta zona se inicia la diferenciación en algunas células del parénquima floemático. El daño se centra principalmente en la región del floema no colapsado, el cámbium vascular y la porción recién formada de xilema, lo que probablemente interrumpe el movimiento tanto de agua como de fotosintatos.
