Conteúdo: ABSTRACT: The objective of this study was to evaluate extent of larval period, larval survival (%), food consumption, and pupal biomass of Spodoptera eridania and Spodoptera frugiperda (Lepidoptera: Noctuidae ) fed on fresh ears of field corn expressing Bt proteins (Cry1F and Cry1F+Cry1A.105+Cry2Ab2). Larvae of Spodoptera spp. survived less than two days when they consumed Bt corncobs and showed 100% mortality. Spodoptera eridania reared on non-Bt corn cobs showed higher larval development (21.6 days) than S. frugiperda (18.4 days) and lower viability (56.4% and 80.2% for S. eridania and S. frugiperda , respectively). A higher amount of corn grains was consumed by S. eridania (5.4g) than by S. frugiperda (3.9g). In summary, this study demonstrated that the toxins Cry1F and Cry1F + Cry1A.105 + Cry2Ab2 expressed in fresh corn cobs contributed to protect ears of corn against S. frugiperda and the non-target pest S. eridania. However, itis important to monitor non-Bt cornfields because of the potential of both species to cause damage to ear sof corn. RESUMO: Este estudo teve como objetivo avaliar o período de desenvolvimento larval, sobrevivência larval (%), consumo de alimento e biomassa pupal de Spodoptera eridania e Spodoptera frugiperda (Lepidoptera: Noctuidae ), alimentadas com grãos verdes de milho Bt que expressam as proteínas Cry1F e Cry1F + Cry1A.105 + Cry2Ab2). As larvas de Spodoptera spp. alimentadas com milho Bt sobreviveram por até dois dias, registrando-se 100% de mortalidade. A espécie S. eridania alimentada com grãos de milho não Bt apresentou um maior desenvolvimento larval (21,6 dias) do que S. frugiperda (18,4 dias), e menor viabilidade larval (56,4% e 80,2% para S. eridania e S. frugiperda respectivamente). Uma maior taxa de consumo de grãos foi observada para S. eridania (5,4g) do que para S. frugiperda (3,9g). Em síntese, este estudo comprova que as toxinas Cry1F e Cry1F + Cry1A.105 Cry2Ab2 expressas em grãos imaturos de milho contribuem na proteção das espigas de milho contra S. frugiperda e a praga não- alvo S. eridania, entretanto, é importante monitorar as lavouras cultivadas com milho não Bt, devido o potencial de ambas as espécies em ocasionar danos nas espigas da planta.2016-01-01T00:00:00ZGenome sequence of Bradyrhizobium pachyrhizi strain PAC48T, a nitrogen-fixing symbiont of Pachyrhizus erosus (L.)

Conteúdo: Bradyrhizobium pachyrhizi PAC48T has been isolated from a jicama nodule in Costa Rica. The draft genome indicates high similarity with that of Bradyrhizobium elkanii. Several coding sequences (CDSs) of the stress response might help in survival in the tropics. PAC48T carries nodD1 and nodK, similar to Bradyrhizobium (Parasponia) ANU 289 and a particular nodD2 gene.2015-01-01T00:00:00ZGenome sequence of Rhizobium ecuadorense strain CNPSo 671T, an indigenous N2-fixing symbiont of the ecuadorian common bean (Phaseolus vulgaris L.) genetic pool.RIBEIRO, R.
