Diamondback moth oviposition nonpreference in cauliflower genotypes

The Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the main plague-insect specie of Brassicaceae plants in Brazil and all over the world. The resistant genotypes use to its control is a promising alternative. This work aimed evaluates the eggs distribution along the plant, the adults' density per plant, and determine the cauliflower genotypes effect in the P. xylostella oviposition. The experiment was carried out at FCAV/UNESP-Jaboticabal Campus Phytossanity Department (Departamento de Fitossanidade). It was evaluated the eggs distribution, the P. xylostella adults density effect using Sharon hybrid, and tests with or without choose choice to determine the P. xylostella nonpreference in the Teresopolis Gigante, Verona, Barcelona, Sharon, Silver Streak, and Piracicaba Precoce genotypes. It is possible conclude that P. xylostella has higher willingness to oviposits in the stem than in the basal leaves. The three couple density of P. xylostella per plant is the best to discriminate cauliflower genotypes regarding the resistance grade to nonpreference choose choice to oviposition. During the P. xylostella oviposition preference tests with choose choice, the genotypes Sharon, Piracicaba Precoce, Barcelona, Verona e Teresopolis Gigante are less desirable to oviposition; while during the no choose choice tests the genotypes did not differ among them.

Agronomic characteristics of 'Prata-anã' and 'Maçã' bananas micropropagated

O experimento foi instalado com o objetivo de estudar o desempenho agronômico de cultivares de bananeira Prata-anã e Maçã, na região de São Manuel-SP. Foram avaliadas as seguintes características de desenvolvimento, no primeiro ciclo de produção: número de dias do plantio à floração e da mesma à colheita, número de rebentos (filhos) emitidos até o surgimento da inflorescência e na época da colheita, número de folhas ativas na época do aparecimento da inflorescência e da colheita, e características de rendimento, como peso médio do cacho, ráquis, penca e fruto, número médio de frutos por penca e cacho, comprimento e diâmetro médio dos frutos. Também foi avaliada a incidência de pragas e doenças. Foi empregado o delineamento inteiramente casualizado, com 2 tratamentos, 15 repetições e 5 plantas úteis por parcela experimental. As duas cultivares foram caracterizadas pelos valores das estatísticas descritivas, média e desvio-padrão, para as características de interesse no experimento. Foram estabelecidas possíveis correlações entre medidas de desenvolvimento e produção. As duas cultivares apresentaram ciclo do plantio até a colheita de 574 dias para 'Prata-anã' e 567 dias para 'Maçã', sendo que o ciclo produtivo foi maior na 'Prata-anã'. Não houve problemas de pragas e doenças em todo o ciclo de produção, nas duas cultivares avaliadas.

Brazilian spotted fever: A reemergent zoonosis

Brazilian spotted fever is caused by the bacterium Rickettsia rickettsii, which is the most pathogenic species of the spotted-fever rickettsiae group and is transmitted by the bite of infected ticks. Amblyomma cajennense is the most important tick species involved in the cycle of this zoonosis in Brazil as it presents low host specificity, great number of natural reservoirs and wide geographic distribution. It was first described in the state of São Paulo in 1929 and later in Rio de Janeiro, Minas Gerais and Bahia. The number of cases decreased in the 1940's with the development of new plague control techniques and antibiotics. In the last decades, the number of new cases has increased. The current review aimed at reporting some of the epidemiological and public health aspects of this reemergent disease with new foci, mainly in the southeastern region of Brazil.

Noise and ultraviolet divergences in the dynamics of the chiral condensate in QCD

The time evolution of the matter produced in high energy heavy-ion collisions seems to be well described by relativistic viscous hydrodynamics. In addition to the hydrodynamic degrees of freedom related to energy-momentum conservation, degrees of freedom associated with order parameters of broken continuous symmetries must be considered because they are all coupled to each other. of particular interest is the coupling of degrees of freedom associated with the chiral symmetry of QCD. Quantum and thermal fluctuations of the chiral fields act as noise sources in the classical equations of motion, turning them into stochastic differential equations in the form of Ginzburg-Landau-Langevin (GLL) equations. Analytic solutions of GLL equations are attainable only in very special circumstances and extensive numerical simulations are necessary, usually by discretizing the equations on a spatial lattice. However, a not much appreciated issue in the numerical simulations of GLL equations is that ultraviolet divergences in the form of lattice-spacing dependence plague the solutions. The divergences are related to the well-known Rayleigh-Jeans catastrophe in classical field theory. In the present communication we present a systematic lattice renormalization method to control the catastrophe. We discuss the implementation of the method for a GLL equation derived in the context of a model for the QCD chiral phase transition and consider the nonequilibrium evolution of the chiral condensate during the hydrodynamic flow of the quark-gluon plasma.

Situacao atual da quimioterapia contra a tuberculose

Actions to overcome a disease are dependant, essentially, on what is known about it. Procedures followed in the past were sometimes bizarre, but justified because of how little was known about the disease. The tuberculosis prechemotherapeutic age was somber due to the high levels of fatalities and morbidity. With the arrival of the chemotherapeutic treatment its prognosis has changed. Tuberculosis declined in the 50's and stabilized in the 80's. Nevertheless, it is back increasing alarming its numbers more than ever; probably because of some factors, among them, the public health system lack of attention and the government's policies, increasing in the migration to and from the endemic areas, development of drug multi-resistant cepa and also to the HIV infection. An universal antimycobacteria chemotherapy treatment is not accepted, maybe because of the number of drugs that are available. Modern chemotherapy, however, has an attack and a maintenance phases with the aim to eliminate the bacillus of fast and slow multiplication, respectively. The treatment period is long, when compared with other infectious diseases, that leads to the lack of compliance. In spite of the available resources in the fight against tuberculosis they seem insufficient to restrain the disease. This has forced the search for new chemotherapy alternatives to avoid strong come back of tuberculosis to the point of being called the 'white plague' well into the 21'st century.

Electroantennographic responses of Heterotermes tenuis (Isoptera: Rhinotermitidae) to synthetic (3Z,6Z,8E)-Dodecatrien-1-ol

The subterranean termite Heterotermes tenuis (Isoptera: Rhinotermitidae) is a pest of great importance for the Brazilian economy as it causes serious damages in commercial reforestations of Eucalyptus spp. and sugarcane cultures. (3Z,6Z,8E)-Dodecatrien-1-ol has been identified as a pheromone of some species of subterranean termites. The objective of this research was to synthesize (3Z,6Z,8E)-dodecatrien-1-ol and determine by electroantennographic (EAG) bioassays the selectivity and sensitivity of H. tenius antennae to its whole worker extract and to the synthetic triene alcohol.
