Aspectos biológicos do peixe-olhudo-dentinho, Synagrops bellus (Actinopterygii: Acropomatidae), da plataforma externa e talude superior do estado de São Paulo, Brasil.

Biological aspects of the blackmouth bass Synagrops bellus from the outer shelf and upper slope along the coast of São Paulo, southeastern Brazil, are presented. The species represented about 71.6% and 9.7% in number of the total catch performed by balloom trawl in the isobaths of 300m and 500m respectively. Body sizes of 266 individuals ranged between 130 and 265mm total length, with sex ratio of 55.9% males, and 44.1% females, where most individuals were in maturation stage. Twenty two food items were found, pointing out Myctophidae fishes, Penaeidea and Caridea shrimps, Brachyuran megalopae, Enoploteuthidae and Cranchiidae cephalopods, pteropods and tunicates. The intestinal coefficient increases as the body size increase, and the number of gill rakers ranged between 16 and 17. Length-weight relationship was WT = 6.0 x 10-6 x TL3.12, r2 = 0.9495. Synagrops bellus is an important link between zooplankton and micronekton, and demersal and pelagic predators in the outer shelf and upper slope in southwestern Brazilian coast.

House-infesting Ants (Hymenoptera: Formicidae) in a Municipality of Southeastern Brazil

In Brazil, since the studies on urban ants started only in the 1980's, the urban myrmecofauna is still poorly known. Therefore, we herein carried out a survey of the myrmecofauna associated with residences in the municipality of Campinas, São Paulo state, Brazil, with the aim of verifying the existing ant species and their dynamics, which may be used in pest management programs. For this survey, baits and manual collection were utilized in the peridomiciles and intradomiciles of 38 houses. 4,308 samples were obtained, 51% of which presented ants, from five subfamilies, 18 genera and 19 species. The predominant subfamily was Myrmicinae, with 8 species. The predominant species was Tapinoma melanocephalum. In the intradomicile, during the diurnal period, the most visited rooms were the kitchen and the living room; during the nocturnal period, the kitchen was the most visited room.

Observations on helminth infections of free-living and captive rheas (Rhea americana) in Brazil

The present work describes helminth infection of eight free-living and 12 captive rheas (Rhea americana) from, respectively, Pantanal of Mato Grosso do Sul State, and Jaboticabal, São Paulo State, Brazil. Captive birds were young and had a high mortality rate, while free-living birds were adult and apparently healthy. Infections were evaluated by post-mortem examination of internal organs and recovery of helminths using standard parasitological procedures. Seven species of nematodes (Sicarius uncinipenis, Torquatoides crotophaga, Deletrocephalus dimidiatus, D. cesarpintoi, Paradeletrocephalus minor, Capillaria venteli and Dicheilonema rheae) and two species of cestodes (Houttuynia struthionis and Chapmania tauricolis) were identified. P. minor, which inhabits the large intestine, was the most common helminth in free-living birds (63.9%). In captive rheas, a mean parasitic load of 173 helminths per host was found. The gizzard of these birds was the most parasitized organ and S. uncinipenis was most common (92.5%). Parasitism of free-living and captive birds and associated pathology are discussed.

Estratégia para erradicação de focos da Doença de Aujeszky em suínos no Estado de São Paulo

Este trabalho teve como objetivo a avaliação de duas estratégias para erradicação de focos da doença de Aujeszky (DA) em suínos criados comercialmente no estado de São Paulo. Foram identificados dois focos da enfermidade, no município de Cerqueira César, um apresentando somente animais sororreagentes (Foco 1) e outro, casos clínicos da doença (Foco 2). Foram avaliadas duas estratégias de erradicação, uma por eliminação dos sororreagentes e outra por despovoamento gradual, com acompanhamento durante 12 meses. A erradicação por eliminação dos sororreagentes foi aplicada no Foco 1 e compreendeu na identificação por exame sorológico, isolamento e abate dos positivos; vacinação dos negativos e reposição no plantel com animais provenientes de propriedade livre. No início dos trabalhos, 68% do plantel era positivo e ao final 51%. No Foco 2 utilizou-se o despovoamento gradual, onde todos os animais foram enviados ao abate sanitário, realizado vazio sanitário nas instalações, seguido pelo repovoamento com animais livres. Esta última estratégia, nas condições desse trabalho, mostrou-se a mais eficaz, pois erradicou a DA.

Novas raças de Bremia lactucae, agente causador do míldio da alface, identificadas no estado de São Paulo

O objetivo deste trabalho foi relatar o surgimento de raças de Bremia lactucae, agente causal do míldio nas principais regiões produtoras de alface do estado de São Paulo. O estudo foi realizado no Laboratório de Melhoramento Genético de Hortaliças do Departamento de Produção Vegetal da UNESP, Campus de Jaboticabal. No período de 2006 e 2007, foram coletados 36 isolados de B. lactucae de diferentes regiões produtoras de alface no estado. Para identificação das raças foram utilizadas as cultivares diferenciadoras conforme o código Sextet. Foram identificadas três novas raças, SPBl:02, SPBl:03 e SPBl:04 com os referidos comportamentos do fungo: (63/31/19/00), (63/63/19/00) e (63/63/03/00). Os genes Dm-14, Dm-17, Dm-18, Dm-37 e Dm-38 conferem resistência a essas novas raças identificadas.

Irrigação e certificação da cafeicultura na Região Centro-Oeste de São Paulo

An unsatisfactory profitability has led to the gradual decline of the coffee plantations in São Paulo. Among the alternatives that arise for solving this problem, two stand out: the irrigation of crops and certification of properties. Even in areas considered suitable for cultivation of arabica coffee (Coffea arabica L.), the use of irrigation can promote an increase in grain yield. In addition, the product certification promotes their differentiation in the market and can improve the economic results of the activity. This study aimed to evaluate the development and productivity of coffee crops subjected to irrigation or not, comparing economic data in the marketing of coffee certified or not, under the conditions of the mid-west region of São Paulo state. The field experimental design was in randomized blocks with two treatments (with and without drip irrigation) and ten repetitions. The costs of production and profitability by selling the final product were calculated. The irrigation increased the development and productivity of coffee. The return on investment took place after the third harvest. Irrigation combined with the sale of certified coffee provided financial balance 1,192% higher than the coffee is not irrigated and non-certified.

Vibrational spectroscopy applied to the study of archeological ceramic artifacts from Guarani culture in Brazil

An archeological artifact can be seen as a chronological element, which helps to determine the age of certain society and to understand the thinking, values and the way of life of this society. Thus, the classification of archeological artifacts is one of the approaches used to study the cultural system of antique societies trying to reconstruct their history. The "Centro de Museologia, Antropologia e Argueologia (CEMAARQ)" of the "Unesp Univ Estadual Paulista" in Presidente Prudente, São Paulo state, Brazil, develops projects within this context (identification and preservation). This is the case of the archeological site named "Lagoa São Paulo-02" discovered in 1993 at the margins of the Parana river in the region of Presidente Epitacio city, São Paulo state, Brazil. This site has ceramic fragments of different shapes and sizes that have a strong influence of traces of the Guarani culture, which is one of the Brazilian native populations. These samples were basically characterized via micro-Raman scattering and Fourier transform infrared absorption (FTIR) spectroscopies. The main objective was to identify the pigments used in the manufacture of the ceramic artifacts and to analyze the composition of the ceramic body to understand how the artifacts were made. Three pigments were found: red, black and white. For the red pigment were identified characteristic bands of hematite, an iron oxide found in the red rocks of the river banks that were eroded by water. The black pigment, probably, is due to the use of vegetal charcoal, which is found in nature as the product of burning organic material such as wood. For the white pigment, the FTIR spectra suggested the use of kaolin, either in the ceramic body or in the proper white pigment, due to the presence of the characteristic bands of the kaolinite. Complementary, the additives applied as anti-plastics were identified as charcoal and quartz, being the latter found in the rocks present in the archeological site. (C) 2010 Elsevier B.V.

A relação trabalho e saúde no setor calçadista de Franca, São Paulo

Este texto busca evidenciar a relação trabalho e saúde em um lócus determinado: a produção calçadista em Franca, interior do estado de São Paulo. A discussão privilegia o processo sócio-histórico da referida atividade econômica em Franca, com ênfase na reestruturação produtiva que, a partir na década de 1990, disseminou parte da produção para as residências dos trabalhadores, constituindo as denominadas Bancas de Pespontos e de Corte em Calçados. Desse modo, a partir do conhecimento empírico, subsidiado pelas visitas a estes empreendimentos e de entrevistas com os trabalhadores e ainda com um relato de caso, enfatiza-se as relações sociais de trabalho que podem agredir à saúde. Todavia, diante da informalidade acabam não sendo consideradas na relação entre saúde e a atividade funcional exercida, ficando estes infortúnios distantes das negociações coletivas, fiscalizações, ou seja, de possíveis mudanças.
