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]

This document is a scientific article that discusses the identification and distribution of sugarcane borers in Mexico. The researchers used genetic sequencing to identify three species of borers and confirmed their presence in the South-central region of Tamaulipas. The borers cause damage to sugarcane crops, impacting their growth and quality. The article acknowledges the support of academic institutions and research laboratories in Mexico and provides references to related studies on the ecology, distribution, and control of sugarcane borers.

Using molecular and traditional taxonomy there was corroborated that the Caryedon species introduced to Mexico in 1966 was C. gonagra (Fabricius) instead of C. serratus (Olivier). Drawings and photographs of male and female genitalia, and a key to identify species in the Serratus subgroup are presented. [ABSTRACT FROM AUTHOR]

Scolytines are widely distributed and function to contribute to the balance of natural ecosystems by participating in decomposition of plant organic matter. However, some species with ambrosial habits now are relevant for avocado crops because they are vectors of phytopathogenic fungi. To determine attraction response of Scolytinae individuals to chemical attractants, we evaluated alpha-copaene, querciverol, alpha-copaene + querciverol, and ethanol in eight-funnel Lindgren-type intersection traps. A negative binomial regression test showed significant effect on captures of Scolytinae in response to different treatments (P < 0.001). Ethanol and the alpha-copaene + querciverol combination were more attractive mostly to species with ambrosial habits. The most abundant species of ambrosia beetles were Corthylus flagellifer Bladford, Corthylus luridus Blandford, Xyleborus volvulus Fabricius, and Corthylus detrimentosus Schedl that responded significantly to both treatments. To use preventive measures against beetles that are vectors of phytopathogenic fungi in avocado orchards, we suggest frequent monitoring using traps baited with ethanol or commercial attractants with alpha-copaene + querciverol.

Painteria leptophylla (DC) Britton y Rose is a rarely studied plant used in ecological restoration of arid and semi-arid zones. Its seeds are consumed by beetles of the Bruchidae family. Species that feed on the seeds were identified, the percentage of seed predation calculated during the pre-dispersal and post-dispersal stages, 2 months and a year after being collected, and germination of healthy and damaged seeds was evaluated. Merobruchus politus Kingsolver damaged 43.2% and Stator limbatus (Horn) 31.5% during pre-dispersal. Predation during post seed dispersal was 51.6% by M. politus and 50.6% by S. limbatus. Average percentage of predation 1 year after the seeds were collected was 51.6% by M. politus and 79.7% by S. limbatus. Thirty-seven percent of seeds without damage germinated and 60% were damaged by S. limbatus, with 16.6% of seeds with one emergence hole germinating and only 7% for M. politus. The percentage of predation by M. politus was greater in pre-dispersal of seeds, which might be because the species is univoltine. Thirty-seven percent of seeds without apparent insect damage germinated compared to seeds with a hole caused by S. limbatus. The greater percentage (60%) of germination, might be because damage by S. limbatus increased permeability and germination. Only 7% of seeds damaged by M. politus germinated because the larger size of the insect consumed most of the seed embryo. [ABSTRACT FROM AUTHOR]
