Resumen Se revisaron trozas de ramas de árboles de canela (Cinnamomum verum) en Cuetzalan, Puebla, México,con perforaciones realizadas por Cnesinus porcatus Blandford, y Taurodemus sharpi (Blandford), el primer registro de asociación con esta planta y un nuevo registro de distribución para Puebla. Sections of cinnamon trees (Cinnamomum verum) branches from Cuetzalán, Puebla, Mexico were examined finding Cnesinus porcatus Blandford, and Taurodemus sharpi (Blandford). These constitute the first report of their association with cinnamon wood and a new distribution record for Puebla. [ABSTRACT FROM AUTHOR]

Se reporta por primera vez la presencia de Specularius impressithorax (Pic) en Honduras alimentándose de un nuevo hospedero, Erythrina berteroana Urb (Fabaceae); la planta o partes de ésta pueden ser utilizadas como medicina-etnomédica, alimento para animales, artesanía, ornamental, agroforestería, leña. El insecto se relaciona directamente con la planta, ya que éste requiere de las semillas para completar su desarrollo. The presence of Specularius impressithorax (Pic) in Honduras feeding in a new host plant, Erythrina berteroana Urb (Fabaceae), is reported for the first time from Honduras; the plant or parts of it can be used as ethnomedical medicine, animal food, crafts, ornamental, agroforestry, and firewood. The insect is directly related to the plant, since it requires the seeds to complete its development. [ABSTRACT FROM AUTHOR]

Algunas especies de Scolytinae han tomado importancia en el cultivo de aguacate al ser vectores de hongos fitopatógenos. El presente estudio se realizó en tres huertos de aguacate ubicados en diferentes altitudes para conocer la diversidad y riqueza de escolitinos en Coatepec Harinas, Estado de México, especies de que pueden ser vectores de hongos fitopatógenos considerados cuarentenarios. Se recolectaron 1,714 escolitinos de 22 géneros y 49 especies en trampas tipo Lindgren cebadas con atrayentes a base de etanol, alfa-copaeno, y querciverol. De éstos, 27 son nuevos registros para el Estado de México. La prueba de índices de Shannon-Wiener (H′), Margalef (D Mg), y de equidad de Pielou (J′), registraron la mayor diversidad de especies de escolitinos en Meyuca de Morelos (1890 msnm) con H′ = 2.075, D Mg = 5.014, y J′ = 0.5836, y la mínima en San Martín El Salto (2470 msnm), con H′ = 0.4495, D Mg = 2.304, y J′ = 0.1660. Los géneros Xyleborus, Monarthrum, Corthylus, y Gnathotrichus registraron la mayor riqueza específica, y la abundancia más alta correspondió a Corthylus flagellifer Blandford, Corthylus luridus Blandford, Xyleborus volvulus Fabricius, Phloeocleptus cristatus Wood, y Araptus schwarzi Blackman, individuos que representaron el 85% de captura. Riqueza y abundancia que corresponde en mayor proporción a escarabajos ambrosiales, potenciales vectores de hongos fitopatógenos, por lo que se recomienda el monitoreo frecuente y determinar la dinámica poblacional y su relación con los factores ambientales. Some species of Scolytinae have become important in avocado production because they can be vectors of phytopathogenic fungi. The present study was done in three avocado orchards at different altitudes to record the diversity and richness of Scolytinae at Coatepec Harinas, State of Mexico. Scolytinae that might be vectors of fungi associated with phytopathogenic fungi are considered quarantined. Scolytinae (1,714) were collected in Lindgren traps baited with attractants based on ethanol, alpha-copaeno, and querciverol, of 22 genera and 49 species, of which 27 are new for the State of Mexico. Significant differences were recorded between the sites, and the Shannon-Wiener index (H′), Margalef (D Mg), and Pielou equity (J′) indices tests recorded the greatest diversity of Scolytinae at Meyuca de Morelos (1890 masl) with H′ = 2.075, D Mg = 5.014, and J′ = 0.5836, and the minimum at San Martín El Salto (2470 masl), with H́ = 0.4495, D Mg = 2.304, and J′ = 0.1660. The genera Xyleborus, Monarthrum, Corthylus, and Gnathotrichus had the greatest species richness. Greatest highest abundance corresponded to Corthylus flagellifer Blandford, Corthylus luridus Blandford, Xyleborus volvulus Fabricius, Phloeocleptus cristatus Wood, and Araptus schwarzi Blackman, individuals that accounted for 85% of the total captures. Richness and abundance corresponded in greater proportion to ambrosial beetles, potential vectors of phytopathogenic fungi. Therefore, frequent monitoring is recommended to determine population dynamics and their relationship with environmental factors. [ABSTRACT FROM AUTHOR]
