Abstract: Dalbergia palo-escrito presents reproduction problems when attacked by insects. In the present study was to evaluate the phenological stage of Apion oedorhynchum LeConte, 1858 that attacks the seed of Dalbergia palo-escrito in the locality of Coatitlamixtla, Xochicoatlán, Hidalgo de Soto, Mexico. Sixteen trees were selected with diameters from 6 cm to 18 cm and heights from 3 m to 17 m, within the altitudinal gradient (High, Medium and Low), these were marked with spray paints and numerical keys were added. The phenological stage of Dalbergia palo-escrito was monitored from the beginning of flowering to pod maturity. A total of 34 pods were collected. The life cycle of Apion oedorhynchum LeConte, 1858 in the pod of Dalbergia palo-escrito 3 months from egg laying to the adult stage.
