ABSTRACT A new species of Machaeriobia Rübsaamen, 1915 (Diptera: Cecidomyiidae) from Brazil. Machaeriobia Rübsaamen, 1915 is a Neotropical genus, until now known from a single species, M. machaerii (Kieffer, 1913), described from Brazil (State of Santa Catarina). That species induces spherical leaf galls on Machaerium sp. (Fabaceae) and its geographical distribution is still restricted to the type-locality. A new galling species, Machaeriobia gemmae, associated with Machaerium macaense (Fabaceae), is described and illustrated (larva, pupa, male, and female) based on material collected in the Parque Nacional da Serra dos Órgãos (State of Rio de Janeiro, Brazil). The new species is unique for its one or two-segmented palpi, deeply notched aedeagus, pupa with... |

This is the first record of Acanthoscelides schrankiae Horn. feeding in seeds of Mimosa bimucronata (DC.) Kuntze. We investigated the pattern of oviposition and seed exploitation by A. schrankiae, and the distribution of mature fruits and seed predation in the inflorescences. We also compared the percentage of predated seeds, the total dry weight of fruits and non-predated seeds, the percentage of aborted seeds, and the percentage of non-emergent insects, among different quadrants of the M. bimucronata canopy. To determine the occurring species, the emergence of bruchids and parasitoids was observed in the laboratory, resulting altogether, only in individuals of A. schrankiae and Horismenus sp. (Hymenoptera: Eulophidae) species, respectively. Mean number... |

Three guilds of bruchid beetles oviposit on seeds at different times and in different ways, i. e., in these guilds some species only oviposit on fruits while on the plant (Guild A), other species only oviposit on seeds exposed in fruits while still on the plant (Guild B) and some only oviposit on seeds once they are exposed on the substrate (Guild C). It has been established that one plant species may be oviposited upon by all three guilds, some only by two guilds and some by only one guild. Before and after the inception of this concept many papers have been published that seem to establish that early oviposition behavior of bruchids was probably onto fruits where they burrowed through the fruit wall and fed on seeds (Guild A). Then, as evolution of the... |

Plantas de cobertura (PC) são fundamentais para a produção de palhada e cobertura do solo no sistema plantio direto (SPD). Entretanto, existem poucas informações do potencial de produção de matéria seca (MS) e do acúmulo de nutrientes por PC no Cerrado brasileiro, quando cultivadas na entressafra, em sucessão à soja e antecedendo ao algodoeiro. Objetivou-se nesse estudo avaliar a produtividade de MS, o acúmulo de nutrientes por PC e seus efeitos sobre a produtividade do algodoeiro. Um experimento foi conduzido no estado de Goiás, Brasil, sendo repetido durante três anos, e constou de 7 tratamentos com PC em cultivos solteiros ou consorciados: Panicum maximum Aruana, Urochloa brizantha cv BRS Piatã, Urochloa ruziziensis, Pennisetum glaucum, Sorghum bicolor... |

ABSTRACT Estimation of carbon stored in forest ecosystems requires accurate biomass prediction tools. The objective of this study was to determine the individual aerial biomass of Prosopis affinis and its distribution by component, to develop allometric models for the estimation of biomass and to estimate biomass expansion factors (BEF) in native forests of Entre Ríos (Argentina). Dendrometric variables on 30 individuals of different diameter classes were measured. Values of total aerial biomass and component biomass (trunk, branches larger than 5 cm in diameter and branches smaller than 5 cm + leaves, flowers and fruits) were determined using the destructive method. Different models were developed, and the best models were selected according to the... |

A Cratília é leguminosa arbustiva nativa do cerrado, tolerante à seca e a solos ácidos e tem potencial para adubação verde e forrageamento. Por essas características, pode ser utilizada pelo agricultor familiar. Objetivou-se verificar a viabilidade das sementes para posterior produção de mudas e doação a produtores familiares. As vagens foram coletadas de 126 plantas da EPAMIG. Após secagem em estufa, as vagens foram pesadas e debulhadas manualmente, resultando em 14,8 kg de sementes. Essas foram armazenadas em sacos de papel em câmara fria e seca. Foram realizadas as análises de pureza física, peso de mil sementes, determinação do grau de umidade e dois testes de germinação, sendo um inicial e outro após dois meses de armazenamento. Os testes seguiram as... |

Os pulvinos, estruturas responsáveis por movimentos foliares, rápidos ou lentos, em resposta a estímulos externos ou endógenos, constituem uma característica marcante das leguminosas. Os ajustes no posicionamento foliar representam um mecanismo eficiente que permite a maximização da fotossíntese em condições adversas. Na literatura disponível, a maioria das informações sobre a estrutura de pulvinos refere-se a poucas espécies de leguminosas, especialmente aquelas que apresentam movimentos rápidos. Neste trabalho é descrita a anatomia do pulvino primário de nove espécies de leguminosas nativas do cerrado com diferentes tipos e velocidades de movimento foliar, buscando identificar padrões e apontar peculiaridades estruturais. O pulvino primário das espécies... |

2-acetyl physcion (2-acetyl-1,8-dihydroxy-6-methoxy-3-methyl-9,10-anthraquinone, 2), a rare anthraquinone, was isolated from Senna macranthera var. nervosa (Vogel) H.S. Irwin & Barneby (Fabaceae). The chemical structure was elucidated and all ¹H and 13C NMR chemical shifts were assigned by NMR one- (¹HNMR, {¹H}-13CNMR, and APT-13CNMR) and two (COSY, NOESY, HMQC and HMBC) dimensional of this natural compound. Furthermore, the minor anthraquinones chrysophanol (3), chrysophanol-8-methyl ether (4) and physcion (5) were characterized by GC-MS analysis. The occurrence of the anthraquinones 3-5 confirms that S. macranthera is a typical representative of the genus Senna. |

Bowdichia virgilioides H.B.K stem bark (Fabaceae), locally known as "sucupira-preta", is a reputed folk-remedy to treat some inflammatory disorders. To validate its traditional claim, the ethanolic extract from B. virgilioides was evaluated in several animal models of inflammation and nociception. The extract at oral doses of 100 to 1000 mg/kg body weight caused a significant inhibition of carrageenan-induced hind paw oedema, suppression of exudate volume and leukocyte immigration in rat pleurisy induced by carrageenan, and reduction of granuloma weights in the model of subcutaneous granulomas promoted by cotton pellets. In addition, the plant extract significantly inhibited the vascular permeability increase induced by intraperitoneal acetic acid. It also... |

The genus Indigofera (Fabaceae) is used in folk medicine to treat gastrointestinal pain. In this study, we investigated the antiulcerogenic properties of Indigofera truxillensis Kunth. Oral administration of MeOH extract did not produce any signals of acute toxicity. The antiulcerogenic activity was assessed in different models of acute gastric ulcers (100% ethanol, piroxicam 30 mg.kg-1, hypothermic restraint stress and pylorus ligature) in mice and rats. The animals were treated with the drugs lanzoprazole (30 mg.kg-1) or cimetidine (100 mg.kg-1) as positive controls depending on the performed model. In another experiment with ethanol-induced ulcers in rats, N-ethylmaleimide (NEM), a sulfhydryl group blocker, was also used. The MeOH extract, at doses of... |

ABSTRACT Floral secretory structures are usually associated with the attraction of pollinators, but may also play an important role in the mechanisms of plant protection. This study aimed to show the diversity of secretory structures present in the developing flowers of 15 legume species belonging to different clades and to associate them with functions other than the pollinator attraction. Buds, flowers and developing axis of inflorescence were processed for surface, histological, and ultrastructural analyses. The species investigated displayed a wide diversity of secretory structures in developing flowers such as phenolic cells and/or tissues, mucilaginous cells, secretory cavities, secretory trichomes and colleters. Each type of secretory structure... |
