To trap the agave weevil, Scyphophorus acupunctatus Gyllenhal, tissue of Agave tequilana F.A.C. Weber var. ‘azul’ and the synthetic pheromone 2-methyl-4-octanone were used. This study evaluated the efficacy of the fermented “pineapple” or “head” of A. tequilana. We also identified volatile compounds attractive to the agave weevil. In the field, between August 2009 and December 2011, we evaluated the following treatments: 1) pheromone, 2) pheromone + fermented agave head, 3) pheromone + non-fermented agave head, 4) fermented agave head, 5) non-fermented agave head, and control (water + insecticide). The volatiles were sampled using the technique of solid-phase microextraction and identified with a gas Chromatograph coupled to a mass selective detector. The traps baited with the pheromone and fermented agave head caught more weevils than did the other treatments. The fermented agave head increased the attraction of S. acupunctatus, while the non-fermented agave head did not contribute significantly. The following volatiles were identified in the fermented agave head: ethyl acetate, ethanol, 2-butanol, and acetic acid. In the non-fermented agave head, 24 volatile compounds were collected, and they were different than those identified in the fermented head. The results obtained indicated that the fermented material was a viable alternative to optimize trapping of S. acupunctatus, because the liberated volatile chemical compounds of the attractant captured a greater number of weevils in the field. Para el trampeo de Scyphophorus acupunctatus Gyllenhal se utiliza el tejido de Agave tequilana F.A.C. Weber var. azul y el compuesto sintético 2-metil-4-octanona (feromona). Sin embargo, para optimizar su captura se requieren otras alternativas. En el presente trabajo se evaluó la eficiencia del tejido de la “piña o cabeza” de A. tequilana, que es la parte central de dicha planta, en estado fermentado, para el trampeo de S. acupunctatus. Así mismo, se identificaron los compuestos volátiles involucrados en la atracción de este insecto. En campo, de agosto de 2009 a diciembre de 2011, se evaluaron los siguientes tratamientos: 1) feromona, 2) feromona + cabeza en estado fermentado, 3) feromona + cabeza sin fermentar, 4) cabeza fermentada, 5) cabeza sin fermentar, y 6) testigo (agua + insecticida). El diseño experimental fue bloques en completamente al azar con seis repeticiones por tratamiento. Los volátiles se muestrearon usando la técnica de Micro extracción en Fase Solida y se identificaron en un cromatógrafo de gases acoplado a un detector selectivo de masas (GC/MS). Las trampas cebadas con la feromona y cabeza en estado fermentado, capturaron más picudos que los otros tratamientos. La cabeza en estado fermentado fue más atractiva que sin fermentar. En la cabeza fermentada se identificaron los siguientes volátiles: acetato de etilo, etanol, 2-butanol, y ácido acético. Mientras que en la cabeza sin fermentar se recolectaron 24 compuestos volátiles diferentes a los encontrados en la fermentada. Esto indica que los volátiles liberados por la fermentación son atractivos y producen sinergia en la respuesta del picudo del agave hacia su feromona de agregación. Los resultados demuestran que el material fermentado es una alternativa viable para optimizar el trampeo de S. acupunctatus en campo.

Protected areas (PAs) are geographical spaces intended to conserve populations, communities, and ecosystems, in which species richness must be maximized, the conserved area must be minimized, and anthropogenic pressure must be reduced. The present study analyzed the representativeness, complementarity, and degree of risk of 25 garter snake species of the genus Thamnophis in the PAs of Mexico. This study proposes that at least 17% of the potential geographic distribution (PGD) of species will be found inside PAs and in areas (Aichi Target 11) with a low human footprint (HF). The PGD of species was associated with the PAs and HF layers to identify where and which species could be at local extirpation risk by human activities. The results indicate that the federal PAs contain 85.2% of the species, while the state PAs contain 77.7% of the species. An average of 13.4% of the PGD of these species is found inside PAs, and two species are found outside. In 13 federal PAs and 10 state PAs, the Thamnophis species present high local extirpation risk from human activities. In total, 37% of species are found in PAs with a medium to very high human footprint; therefore, their persistence could be at local extirpation risk. Compared to other taxa, species of the genus Thamnophis are well represented. However, the PDG of more than half of the species achieves Aichi Target 11.

Introduction: The presence and structure of vegetation in urban areas have an impact on the composition of bird communities. Green areas with a higher ratio of introduced vegetation tend to have a greater homogenization of avifauna, whereas green areas with a high ratio of native vegetation have a greater diversity of birds. In several studies carried out in urban areas of Mexico, the factors of vegetation are not considered. Therefore, the responses of the species to vegetation types in terms of richness and diversity are unknown. Objective: To analyze the composition of bird species in the green areas of Ciudad Victoria, Tamaulipas, and evaluate the response of bird communities in areas with differences in vegetation composition. As well as to analyze the relationship between the trophic guilds in birds and vegetation in urban areas. Methods: Three sampling sites were established in Ciudad Victoria, Tamaulipas, Mexico, based on two criteria: similar sampling area (ha) and differences in vegetation characteristics. Monitoring took place between January and December 2020, with three monthly visits in each site for a total of 108 visits, using the direct visual method. Results: We identified 98 species (11 orders, 28 families). The most abundant species were Quiscalus mexicanus and Molothrus aeneus. Differences in species richness were found for each site. The insectivorous and granivorous were the dominant guilds. An association between the guilds and the study sites was determined, where most were linked to mixed native vegetation, compared to homogeneous or introduced vegetation. Conclusions: The urban areas studied maintained a notable number of birds, and several of them presented some category of risk or endemism. This demonstrates the importance of these green areas composed of native vegetation as a refuge for birds and highlights the need to conserve and protect these areas within Ciudad Victoria and similar cities. Introducción: La presencia y estructura de la vegetación en áreas urbanas tiene un impacto en la composición de las comunidades de aves. Las áreas verdes con una mayor proporción de vegetación introducida tienden a presentar una homogeneización de avifauna, mientras que las áreas verdes con alta proporción de vegetación nativa presentan mayor diversidad de aves. En varios trabajos realizados en áreas urbanas de México, estos factores no son tomados en cuenta. Por lo tanto, se desconocen las respuestas de las especies en términos de riqueza y diversidad. Objetivo: Analizar la composición de especies de aves en las áreas verdes de Ciudad Victoria, Tamaulipas y evaluar la respuesta de las comunidades de aves en tres áreas verdes con diferente composición de vegetación. Así como analizar la relación entre los gremios tróficos de aves con los elementos de la vegetación en las áreas urbanas. Métodos: El estudio se llevó a cabo en tres sitios de muestreo de Ciudad Victoria, Tamaulipas, México, con base en dos criterios: área similar de muestreo (ha) y diferencias en las características de la vegetación. Los monitoreos se realizaron de enero a diciembre de 2020, con tres visitas mensuales en cada sitio para un total de 108 visitas, utilizando el método visual directo. Resultados: Identificamos 98 especies (11 órdenes, 28 familias). Las especies más abundantes fueron Quiscalus mexicanus y Molothrus aeneus. Hubo diferencias en la riqueza de especies para cada sitio. Las insectívoras y granívoras fueron las dominantes. Se determinó una asociación entre los gremios y los sitios de estudio, donde la mayoría están relacionados con la vegetación mixta, comparado con la vegetación homogénea o introducida. Conclusiones: Las áreas urbanas estudiadas mantuvieron un número notable de aves, y varias de ellas presentaron alguna categoría de riesgo o endemismo. Esto demuestra la importancia de estas áreas verdes como refugio de aves y resalta la necesidad de conservar y proteger dichas áreas dentro de Ciudad Victoria y ciudades similares.
