The species Cotesia alius (Muesebeck, 1958) (Hymenoptera: Braconidae: Microgastrinae) is a larvae parasitoid of Opsiphanes invirae amplificatus Stichel (1904) (Lepidoptera: Nymphalidae). Hymenopteran parasitoids larvae and pupae are recorded acting as defoliators of palm. Concerning the scientific and economic importance of these interespecific relationship, and aiming to increase the knowledge to natural and conservative biological control, the present study records in the State of Rio Grande do Sul State, Brazil, some data on the biology of this C. alius as larval parasitoid of O. invirae amplificatus Stichel (1904). Based on 35 postures were recorded 4581 cocoons. On 16 postures (48%) observed all cocoons were open and empty, indicating that all parasitoids emerged (Normal). In the 19 remaining postures (52%) (Altered), 134 cocoons (6%) were closed with C. alius intacts in six postures (40%) (Intacts) or remains (fragments) (44%), and in Eulophidae intact within three postures (16%). These data can be used in mass rearing of parasitoids, and biological control of defoliator’s palm.

Viticulture is an activity of economic importance in the state of Rio Grande do Sul, especially in Serra Gaúcha, which is the major grape-producing region. However, an increase in cultivated areas has been observed in other municipalities in the state. The aim of this study is to characterize mite diversity and community behavior on different varieties, recognizing which predatory species have potential to control phytophagous mites associated with Europan varieties in the Taquari Valley, Rio Grande do Sul state. The study was conducted in vineyards located in the municipalities of Marques de Souza: ‘BRS Vitória’ and cv ‘Itália’ “m”; Imigrante: cv ‘Itália’ “i”; Dois Lajeados: cv ‘Itália’ (c and f), ‘Tannat’ and ‘Chardonnay’; and Putinga: ‘Champanhe’ and ‘Moscato’. Samplings were carried out monthly in the period ranging from March 2017 to March 2018, during which twenty plants were randomly collected from each variety. Three leaves were clipped from each plant; one from the apical third, one from the median third, and one from the basal third, totaling 60 leaves per area. A total of 10,533 specimens were collected, belonging to 12 families, 38 genera, and 53 species, along with those belonging to the suborder Oribatida. The ‘Itália’ “c” variety had the highest abundance (2,012), followed by ‘Moscato’ (1,788) and ‘BRS Vitória’ (1,593). Phytoseiidae had the highest diversity among the mite families observed, with 20 species followed by Tetranychidae (8). The most abundant species were Polyphagotarsonemus latus (Banks) (3,420) and Euseius concordis (Chant) (565), present throughout the study period. ‘Chardonnay’ variety had the highest similarity (72.55%) among mite fauna compositions and the highest dissimilarity occurred between ‘BRS Vitória’ and ‘Champanhe’ varieties (95.48%). Environments evaluated in Dois Lajeados and Putinga were the most homogeneous concerning mite fauna diversity and abundance.

Resumo O estudo examinou o fenômeno da especialização produtiva em atividades industriais de alto potencial poluidor-APP. Os objetivos da análise foram (a) avaliar, a partir de dados secundários, a importância atual das indústrias de APP para a economia do RS; e (b) mapear no território gaúcho essas indústrias, a fim de observar a concentração espacial dessas atividades. Para tanto, analisou-se dados de emprego, estabelecimentos, produção e exportação das atividades industriais de APP, no período de 2007 e 2014. Embora os resultados não tenham indicado mudanças substanciais ao longo desses oito anos, foi possível estabelecer um panorama do setor industrial de APP gaúcho, o qual servirá de base para pesquisas futuras sobre a formação de paraísos de poluição no RS. Abstract The study analyzed the phenomenon of productive specialization in industrial activities of high pollution potential-HPP. The objectives of the analysis were (a) to evaluate, from secondary data, the current importance of HPP industries for the State Rio Grande do Sul (RS/Brazil); and (b) to map in the territory these industries and to observe the spatial concentration of these activities. Therefore, it was analyzed employment data, establishments, production and export of industrial HPP activities, in the period 2007 and 2014. Although the results did not indicate substantial changes over these eight years, it was possible to establish an overview of the industry HPP in RS, which will form the basis for future research on the formation of pollution havens in RS.

The objective of this research was to analyze the control methods of ovine verminosis in the agriculture family of Pinheiro Machado municipality, located in the state of Rio Grande do Sul (RS), Brazil. In 2015, available information regarding agriculture on anthelmintics was collected by conducting interviews and by applying questionnaires to 32 sheep breeders. There were 11 active principles and 34 commercial names of medications registered for deworming. All the producers used anti-parasite drugs to control sheep verminosis, and 90% of the producers applied vermifuges without taking into account technical criteria. Only 1.8% gave a suitable destination to medical devices packages. Sheep farmers increased the frequency and dose usage of antiparasitic drugs, the aforementioned shows as consequences an increase in parasitic resistance to deworms and an environmental impact. In order to increase production and reduce chemicals that are harmful to the environment, sheep breeders shall use phytotherapy, homeopathy, biological control, rotational grazing, and the Famacha method.

Terrestrial Isopods were sampled in four protected Atlantic Forest areas located in Serra do Mar, state of São Paulo, southeastern Brazil. A total of 2,217 individuals of six species (Atlantoscia sp., Benthana werneri, Pseudodiploexochus tabularis, Pudeoniscus obscurus, Styloniscus spinosus and Trichorhina sp.) were captured in pitfall traps. The exotic species S. spinosus is recorded for the first time for the Americas. Another introduced species, P. tabularis, previously recorded only from the state of Rio Grande do Sul, had its geographic distribution extended to the state of São Paulo. The most abundant isopods in this study belong to an undescribed species of Atlantoscia.

The Right

Treatment of phenylketonuria (PKU) includes the use of a metabolic formula which should be provided free of charge by the Unified Health System (SUS). This retrospective, observational study sought to characterize judicial channels to obtain PKU treatment in Rio Grande do Sul (RS), Brazil. Lawsuits filed between 2001- 2010 and having as beneficiaries PKU patients requesting treatment for the disease were included. Of 20 lawsuits filed, corresponding to 16.8% of RS patients with PKU, 19 were retrieved for analysis. Of these, only two sought to obtain therapies other than metabolic formula. In all the other 17 cases, prior treatment requests had been granted by the State Department of Health. Defendants included the State (n = 19), the Union (n = 1), and municipalities (n = 4). In 18/19 cases, the courts ruled in favor of the plaintiffs. Violation of the right to health and discontinuation of State-provided treatment were the main reasons for judicial recourse. Unlike other genetic diseases, patients with PKU seek legal remedy to obtain a product already covered by the national pharmaceutical assistance policy, suggesting that management failures are a driving factor for judicialization in Brazil.

Several stink bugs in the subfamily Pentatominae are crop pests or have the potential to damage plants of economic importance. In the Brazilian state of Rio Grande do Sul, where agriculture plays a major role in the economy, the knowledge about pest stink bugs is fragmented and, in some instances, outdated. This work provides a summary of Pentatominae species recorded in Rio Grande do Sul feeding on the four most important grain crops for the state, i.e. soybean, rice, maize, and wheat, plus canola, an emerging crop. This survey is enhanced with new records from scientific collections, a short diagnosis for each species, distribution maps, an identification key, and carefully illustrated to allow for species recognition in the field. With this work, we aim to reunite the scattered knowledge of the group in one single revision, and provide a useful tool for identifying the pest stink bugs of Rio Grande do Sul.
