In rural areas of Mexico, the native "escamolera" ant (Liometopum apiculatum Mayr) is socioeconomically important. However, this ant is being exploited unsustainably, and studies of habitat of this species in central Mexico are nonexistent. During spring-summer 2012, fourteen habitat variables were evaluated, habitat use by the ant was identified and its nest density was estimated. Data were analyzed with stepwise logistic regression, correspondence analysis, Chi-square and simultaneous Bonferroni confidence intervals analyses, and the minimum Akaike Information Criteria. The variables that better described the presence of the ant were width of the agave pineapple, percentage of agaves infested with scale insects, woody plant-cacti-agave density, soil... |

No presente estudo procedeu-se à caracterização tecnológica de alguns híbridos de sisal em comparação com a espécie comum (Agave sisalana Perr.), colhidos no Centro Experimental de Campinas em 1987. A densidade básica (0,172 a 0,249g/cm³) e o teor de matéria seca (16,91 a 24,82%) cresceram da base para a extremidade das folhas de sisal, contrastando com os teores de fibra têxtil (37,71 a 23,43%) e celulósica (21,75 a 14,56%), que decresceram a partir da base das folhas. As fibras celulósicas na base das folhas foram mais curtas; com maior lúmen e menor parede celular. O comprimento das fibras celulósicas do sisal comum (2,63mm) foi maior que os híbridos (1,39 a 2,09mm): estes não apresentaram superioridade tecnológica em relação ao sisal comum. |

ABSTRACT The effect of plant growth-promoting bacteria inoculation on plant growth and the sugar content in Agave americana was assessed. The bacterial strains ACO-34A, ACO-40, and ACO-140, isolated from the A. americana rhizosphere, were selected for this study to evaluate their phenotypic and genotypic characteristics. The three bacterial strains were evaluated via plant inoculation assays, and Azospirillum brasilense Cd served as a control strain. Phylogenetic analysis based on the 16S rRNA gene showed that strains ACO-34A, ACO-40 and ACO-140 were Rhizobium daejeonense, Acinetobacter calcoaceticus and Pseudomonas mosselii, respectively. All of the strains were able to synthesize indole-3-acetic acid (IAA), solubilize phosphate, and had nitrogenase... |

Abstract The effects of ultrasound-assisted extraction (UAE) at different ultrasound power densities (UPDs; 40, 80, and 120 mW/mL) and solid:liquid (S:L) ratio (1:2, 1:3, and 1:6) on the extraction of carbohydrates from Agave tequilana plant of different ages were evaluated. Extracts obtained (6- and 7-year-old plant) were analyzed in the yield of carbohydrates (YC), fructan (FRU) content, simple sugars, fructan profile and the average degree of polymerization (DPn). UPD, S:L ratio, and plant age all affected YC, FRU, and DPn. Maximum YC and FRU were obtained from the older agave with UPD and S:L ratio of 120 mW/mL and 1:6, respectively; while glucose, fructose, and sucrose were highly released from the younger plant. Agave of 7-year-old presented the... |

Abstract Agave tequilana Weber azul variety is a valuable source of fructans. In this study, a response surface methodology was employed to optimize the extraction yield of fructans from agave pines. A Box Behnken factorial design was applied to evaluate the effects of several conditions such as extraction temperature, water raw material ratio and extraction time on extraction yield. Under the optimum extraction conditions (extraction temperature of 79.1 °C, water raw material ratio of 5.13 mL/g, and extraction time of 1.48 h) fructans extraction yield was 83.12%. The chromatographic profile of the agave crude extract presented four peaks, out of which fructans were the most preponderant (~87%). The obtained results suggest that the response surface... |

En las zonas rurales de México, la hormiga "escamolera" (Liometopum apiculatum) es socioeconómicamente importante porque sus larvas, conocidas como "escamoles" se extraen de los hormigueros y son vendidos para el consumo humano. Sin embargo, la hormiga escamolera está siendo explotada de manera no sostenible y no existen estudios sobre el uso del hábitat por esta especie en el centro de México. Para identificar el uso del hábitat por la hormiga escamolera, durante la primavera-verano de 2012, se evaluaron catorce variables del hábitat en parcelas circulares de 20 m de diámetro, de 54 nidos de hormigas y de 162 parcelas seleccionadas al azar; asimismo, se estimó la densidad de nidos en sitios con tres niveles de perturbación del ecosistema. Asimismo, para... |

El gusano rojo del maguey (Comadia redtenbacheri) es utilizado como alimento de varios estados de México. El largo ciclo de vida, la depredación humana y natural, la destrucción de su hábitat durante la colecta y el consecuente incremento en el costo para su consumo han reducido la población del insecto, por lo que se busca la implementación de un sistema de manejo del insecto. Se obtuvieron muestras de campo y comerciales de Comadia redtenbacheri para colectar a los parasitoides que afectan su desarrollo larval. Se encontraron como especies parasíticas al taquínido Acantholespesia texana (Aldrich & Webber) que se eporta como un nuevo registro para México y al himenóptero Lissonota fascipennis Townes, un nuevo registro para el hospedero y en el país.... |
