| Chrysodeixis includens (Walker, 1858) (Lepidoptera: Noctuidae) tem sido considerada uma praga severa em lavouras como a soja e o algodão, espécies de grande importância econômica para o Brasil. Inseticidas à base de baculovírus, um grupo de vírus patogênicos a insetos, têm sido usados com sucesso para controlar lepidópteros-praga na agricultura brasileira. A multiplicação em massa do vírus para a produção comercial deve partir da seleção de isolados virais com alta virulência para resultar em um produto com alta efetividade contra a praga no campo. Dois isolados virais, obtidos de lagartas infectadas de Chrysodeixis includens em plantações de soja em Buritis-MG, foram purificados, identificados, analisados e avaliados quanto à atividade biológica por meio... |

| ABSTRACT Soils formed in high mountainous regions in southern Brazil are characterized by great accumulation of organic matter (OM) in the surface horizons and variation in the degree of development. We hypothesized that soil properties and genesis are influenced by the interaction of parent materials and climate factors, which differ depending on the location along the altitudinal gradient. The goal of this study was to characterize and classify the soil, evaluate soil distribution, and determine the interactive effects of soil-forming factors in the subtropical mountain regions in Santa Catarina state. Soil samples were collected in areas known for wine production, for a total of 38 modal profiles. Based on morphological, physical, and chemical... |

| As part of a long-term investigation on the evolution of Passiflora L., we investigated the divergence ages of the genus and diversification of its subgenera, relating them with biogeographical and/or historical events, and other characteristics of this taxon. The main aim of the present work was to evaluate the biogeographic distribution of this genus to better understand its evolutionary history. This is the first time that representatives from South American and Old World Passifloraceae genera have been studied as a group comprising a total of 106 widely distributed species, with representative samples of the four suggested subgenera. Seven DNA regions were studied, comprising 7,431 nucleotides from plastidial, mitochondrial and nuclear genomes.... |
