This study aimed to determine the prevalence and geographical distribution as well as the factors and areas of risk associated with bovine cysticercosis in the State of Sao Paulo. 34.443 cattle, males and females with ages from 18 to 60 months were inspected. The animals were from 97 cities in the state of Sao Paulo and identified and slaughtered in the period October 2010 to August 2011, in a refrigerator located in Ipua - SP, under the supervision of SIF 1387. The state of Sao Paulo was divided into regional centers, and the data of the municipalities belonging to its core, were grouped according to the Department of Agriculture and Food Supply of Sao Paulo, totaling 13 cores studied. Based on these results, we can conclude that of the 97 cities analyzed, cattle were found positive for the disease in 86. The average prevalence of bovine cysticercosis in the state of Sao Paulo was 4.80 %, while the core inflation Franca and Barretos were the ones with the highest number of cases illness during the analysis period. Moreover, the largest number of cases in these core coincided with the lowest human development index covering education, with the largest acreage of coffee (core Franca) and also as the largest area of cane sugar grown (core Barretos) in these locations, which in turn may indicate that the presence of labor, temporary labor in rural areas, combined with socioeconomic/cultural factors might contribute to the spread and establishment of bovine cysticercosis in these areas.

Brazilian southeastern region has soil and climate conditions suitable for the growing of rubber trees, and most part of national yield arises from São Paulo State. The aims proposed for this work were to determine the diversity, the richness and the seasonal occurrence of mites found in a rubber tree crop in a triennial survey with monthly samplings, as well as to estimate the populational density of the major phytophagous species. This study found 74,407 mites from 26 species belonging to 10 families. The phytophagous and predators represented 95.4% and 3.9% of the total abundance, respectively. Twelve species were rare, six accessories and eight constant. The families Phytoseiidae and Tydeidae had the greatest richness (five and four species, respectively). The most numerous species was Calacarus heveae Feres (50,573), with great abundance at the end of rainy season until the beginning of dry season. Among predators, the most abundant were Zetzellia quasagistemas Hernandes & Feres (1,345), Pronematus sp. (455), Zetzellia agistzellia Hernandes & Feres (409) and Euseius citrifolius Denmark & Muma (243). C. heveae had greatest densities on March and April 2003, and Lorryia formosa Cooreman and Tenuipalpus heveae Baker on March and May 2001, respectively. Many stigmaeids were observed in association with colonies of L. formosa preying their eggs and immatures.

Este estudo foi desenvolvido no riacho Taquaral, que integra a Bacia hidrográfica do Pirapitingui, localizado na cidade de Itu, estado de São Paulo. A pesquisa foi conduzida com a finalidade de comparar a diversidade da ictiofauna em três pontos distintos de um trecho do riacho, além de obter variáveis ambientais físicas e químicas que poderiam distinguir as características abióticas e influenciar as particularidades bióticas de cada ponto. As coletas foram realizadas com materiais de pesca que consistiram em redes de espera, peneira e armadilhas de fundo do tipo covo. Uma lista das espécies foi elaborada utilizando-se de cálculo de riqueza, abundância relativa e abundância total por ambiente amostrado para então realizar as análises de diversidade se utilizando do Índice de Shannon por local de coleta, o qual assume que os indivíduos são amostrados ao acaso com origem em uma população indefinidamente grande e que todas as espécies são representadas na amostra. Além desse índice foram considerados os índices de similaridade de Jaccard, que compara a similaridade das espécies de dois locais levando em conta a presença ou ausência das espécies e o Índice de Morisita -Horn que abrange também a abundância dessas espécies. No total foram capturados 3490 exemplares pertencentes a 5 ordens e 7 famílias, em um total de 15 espécies, sendo que em um dos pontos (ponto1) foi observado menor quantidade de espécies e menor número de exemplares (8 espécies e 49 exemplares). Os demais pontos (pontos 2 e 3) obtiveram igual número de espécies (13), além dos maiores números em exemplares ( 1447 e 1994, respectivamente). Os resultados apontam a existência de diferenças nas características ambientais, também resultantes de influências antrópicas na região e consequente diferenciação na diversidade dos três pontos amostrados. A diversidade observada no Ponto 1, a partir do Índice de Shannon, foi a maior em...

The contamination of the physical environment occurs as a result of the lack of planning and inadequate management of hazardous products. Due to the difficulty of the characterization and study of soil and groundwater, the contamination has been long neglected. The characterization of these areas by research techniques through direct methods such as physical and chemical analysis, are widely used in the diagnosis and monitoring. However, despite presenting quantitative results, this method is not representative in spatial terms. The purpose of this work is to bring geophysical complementation with the diagnosis, bringing the spatial element for the detection of the contamination plume. In the study area, there was a railway accident in 1999 in which three wagons fell and spilled 240,000 L of diesel onto the soil. The main objective is to assess the presence of contaminants in the residual phase and dissolved in the subsurface, using the technique of Electrical Tomography (ETR), understand the effects of natural attenuation process in the degradation of hydrocarbons and changes in electrical properties in soil and groundwater. The results allowed the definition of three distinct patterns of resistivity region with presence of dissolved phase, set in a historical chemical analyzes: low values (> 60Ω.m) associated with the presence of hydrocarbons in an advanced stage of degradation, intermediate values (260Ω.me 511Ω .m) indicative of coexistence of residual hydrocarbons and dissolved phase, and high values (> 1000Ω.m), which reveal the prevalence of residual phase with incipient degradation, possibly in high toxicity concentrations for effective action of biodegradation processes. The diagnostic of areas with potential accumulation of residual phase can subsidize the planning of remediation techniques and promote the complete decontamination of the area
