Efeito da alimentação do adulto na qualidade do endoparasitoide larval da broca comum da cana-de-açúcar

Aiming qualitative improvements in the mass rearing of Cotesia flavipes (Cameron, 1891) (Hymenoptera: Braconidae) in laboratory, tests were conducted with adults feed before parasitism on Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) larvae, using 14 artificial diets based on sucrose, brewer yeast and honey. The design was completely randomized with 15 treatments and five replications. The biological parameters evaluated in F1 and F2 generations were: number of adults emerged; sex ratio; adult emergence percentage; weight of pupae mass; and male and female longevity. The highest average of emerged adults were 85 in diet with sucrose 5% for F1 generation, and 91 in diet with sucrose 5% + yeast brewer 2,5% for F2; the smaller average of adult emergency were 63.60 in diet with honey 5% + yeast brewer 2.5 % for F1 generation and 66.80 in diet with honey 5% for F2. Diets that produced more females were honey 5% + yeast brewer 2.5%, showing the sex ratio of 0.82 for F1 generation, and sucrose 10% + 2.5% yeast brewer 2.5% (0.75) for F2, while sucrose 10% + yeast brewer 2.5% (0.60 for F1) and honey 2.5% (0.59) provided fewer females for F2 generation. The highest percentage of adult emergence were 93.90% with the diet containing sucrose 2.5% + yeast brewer 2.5%) and 93.89 % with honey 5% + yeast brewer 2.5%, and the lowest 81.71% (honey 5% + yeast brewer 2.5%) for F1 and 78.96 % (honey 5%) to F1 and F2, respectively. The diet with Mel 2.5% produced greater weight of pupae mass. The adult longevity did not differ significantly for all diets in F1 and F2 generations. Diets containing 5% or 10% of sucrose or honey provide, in general, improve the qualitative development of C. flavipes in mass rearing.

Análise da implantação do programa Eco-Escolas-Semente Viva na E. M. Sylvio de Araújo, Rio Claro-SP

This study was conducted in partnership with the Extension Project in Education Environmentally Semente Viva and it is an assessment of the environmental education methodology applied by the Group in 2014, at the Municipal School Sylvio de Araújo, in Rio Claro- SP. The implemented methodology was named Programa Eco Escolas- Semente Viva and it was based on the use of certain bases of the Eco-Schools program, created by the FEE (Foundation for Environmental Education), with some adjustments in accordance with the goals of the Group. The study followed the participatory research method, and the data collection gave up through participant observation, literature and documentary. The chapters present the description and analysis of the events that represent the implementation process of the Programa Eco Escolas- Semente Viva. The meetings with the community and environmental education activities with children from 1st to 4th year are described in detail, and is given regarding the analysis of situations, from the point of view of one of the members of the Semente Viva Group

Estudo histomorfométrico do processo de cicatrização óssea em defeitos cirúrgicos de camanho crítico em calvárias de ratos preenchidos com polímero de mamona

Objectives: The aim of this study was to evaluate the behavior of the polymer histomorphometrically castor during the healing process of defects of critical size calvarial preparations in rats. Materials and Methods: Twenty animals underwent a surgical procedure that was to be held in the calvaria of each animal a critical defect of 8 mm in diameter with a drill trephine. The rats were divided into two groups according to the following procedures: group C received no treatment and the bone defect site was filled with blood clot, group M, the bone defect was filled with castor oil polymer particles. The animals were sacrificed 180 days after the surgical procedures. After routine laboratory procedures the specimens were subjected to analysis histomorphometric. Results: In groups C the newly formed bone tissue was well developed, with adjacent areas of osteoid matrix rich in osteoblasts, and restricted to the vicinity of the edges of the defect. In animals of group M was observed newly formed lamellar bone tissue restricted to the vicinity of the defect edges and particles of polymer Castor distributed throughout the defect. There was a higher percentage of newly formed bone area was statistically significant in group C compared to animals in group M. Conclusions: Within the limits of this study can conclude that the castor oil polymer is biocompatible and had kept the area during the healing of critical size defects in surgically prepared rat calvariae.

Theta Burst Stimulation Over the Right Broca's Homologue Induces Improvement of Naming in Aphasic Patients

Improvements of language production in aphasic patients have been reported following repeated 1-Hz transcranial magnetic stimulation over the nondamaged right hemisphere. Most studies examined aphasic patients in the chronic phase. The effect of transcranial magnetic stimulation application in acute or subacute patients has not been systematically studied. We aimed to evaluate whether continuous theta burst stimulation, an inhibitory protocol with a shorter application time than the common 1-Hz protocol, is able to improve naming performance in aphasic patients in different poststroke phases.

Variabilidade espacial de uma cultura de milho (Zea mays): influência da distribuiçao vertical de semente

Com o objetivo de estudar a influência da distribuição vertical de semente na variabilidade espacial da implantação de uma cultura de milho em diferentes sistemas de preparação do solo (mobilização convencional, mobilização mínima e sementeira direta), realizaram-se nas campanhas de 2011 e 2012 dois ensaios de campo na região do Alentejo. A avaliação da distribuição vertical de semente fez-se pela determinação da profundidade de sementeira medindo o comprimento do mesocótilo em plântulas de milho. Em sementeira direta foram ainda testadas duas velocidades de trabalho. Os resultados demonstraram que o melhor desempenho de distribuição vertical da semente foi conseguido em sementeira direta com o aumento de velocidade de trabalho de 4 para 6 km h-1 (com um coeficiente de variação, CV, de 10,1%). Uma ANOVA de duplo fator demonstrou que a resistência mecânica do solo e a velocidade de trabalho determinaram diferenças significativas na profundidade de sementeira; a profundidade de sementeira causou diferenças significativas no tempo médio (TME) e percentagem de emergência (PE) da cultura. Os elevados CV observados sugerem a necessidade de uma melhor calibração dos dispositivos de controlo de profundidade dos semeadores por parte dos operadores em campo ou o aperfeiçoamento dos mesmos.
