| The objective of this work was to list potential candidate bee species for environmental risk assessment (ERA) of genetically modified (GM) cotton and to identify the most suited bee species for this task, according to their abundance and geographical distribution. Field inventories of bee on cotton flowers were performed in the states of Bahia and Mato Grosso, and in Distrito Federal, Brazil. During a 344 hour sampling, 3,470 bees from 74 species were recovered, at eight sites. Apis mellifera dominated the bee assemblages at all sites. Sampling at two sites that received no insecticide application was sufficient to identify the three most common and geographically widespread wild species: Paratrigona lineata, Melissoptila cnecomola, and Trigona spinipes,... |

| Abstract: The objective of this work was to determine the survival pattern of the cotton boll weevil during fallow in Midwestern Brazil. The percentage of adults that remained in the cotton reproductive structures, the percentage of adults searching for shelters, and the longevity of adults fed on pollen and nectar as alternative food sources were determined. For this, four populations were sampled in cotton squares and bolls, totaling 11,293 structures, from 2008 to 2012. The emergency of cotton weevil adults was monitored from the collection of the structures until the next cotton season. In the laboratory, newly-emerged adults were fed on hibiscus or Spanish needle, and their life span was monitored individually. Most adults (85.73%) left the... |

| O interesse nacional pelo cultivo comercial de shiitake é crescente, devido às suas propriedades nutricionais e medicinais, e ao seu apreciável sabor. O cultivo deste cogumelo constitui uma alternativa rentável de diversificação das atividades de uma propriedade agrícola. Este trabalho teve como objetivo determinar, no Estado de São Paulo, a viabilidade econômica do cultivo de shiitake considerando-se um ciclo de 14 meses, em 1000, 2000, 3000 e 4000 toros de eucalipto. As escalas de produção de 2000 e 4000 toras apresentaram os menores custos de produção kg-1 de shiitake fresco, cerca de R$6,50 e os melhores índices de lucratividade, aproximadamente 34%. A análise de viabilidade econômica mostrou resultados favoráveis para as três maiores escalas de... |
