| description | To provide strategies to control an unusual pine sawfly outbreak in Oaxaca, the objective of this study was to identify the species and estimate cocoon density and life cycle of the defoliator. For species identification, we followed the taxonomic classification developed by David R. Smith and coworkers, using adult female and male sawflies. Density was evaluated in 10 sites; on each site, one tree was selected at random. From this tree we defined 1 m2 sampling units at 1 m, 2 m and 3 m from the tree stem. We also proposed a general life cycle based on field data and cocoons kept at laboratory conditions. We identified the presence of Zadiprion howdeni as the invasive sawfly in the region. In Ixtlán, the average density of the cocoons was 37.92 ± 8.63 per m2, with significant differences between plots. No significant differences were found in the average density of the cocoons per m2, regarding tree distance. However, significant differences in cocoon’s numbers were observed between males and females per m2. The sawfly´s longest life cycle stage is as a cocoon and the most sensitive stage of life was the adult. Management strategies are provided for the different stages of sawflies. To consolidate these strategies, it is important to continue gathering basic knowledge of the biology and ecology of this defoliating species. |

En los bosques de Ixtlán de Juárez se detectó un brote inusual de mosca sierra (Hymenoptera: Diprionidae), por lo que este trabajo tiene como objetivo identificar taxónomicamente a la especie afectante y estimar su densidad y ciclo de vida. La identificación se basó en la observación de especímenes adultos de ambos sexos, siguiendo las claves taxonómicas desarrolladas por David R. Smith y colaboradores. La densidad de capullos se evaluó en 10 sitios, dentro de los que se seleccionó al azar un árbol, a partir del cual, se establecieron tres cuadrantes de muestreo de 1 m2, ubicados a 1 m, 2 m y 3 m de distancia del fuste. El ciclo de vida de la mosca se determinó con información obtenida en campo y laboratorio, dando seguimiento a los capullos recolectados. Se determinó y registró a Zadiprion howdeni como defoliador de pinos en la región de estudio. La densidad promedio de capullos por metro cuadrado fue de 37.92 ± 8.63/m2, con diferencias significativas entre parcelas. No se encontraron diferencias significativas en la cantidad promedio de capullos por metro cuadrado respecto a la distancia del árbol, sin embargo, se observaron diferencias significativas en la cantidad de capullos por unidad de superficie entre machos y hembras. La etapa más larga del ciclo de vida de la mosca es como capullo y la etapa más sensitiva es como adulta. Se brindan estrategias de control para cada etapa de vida y se recomienda continuar con el estudio biológico y ecológico para consolidar las estrategias de manejo de Z. howdeni.
