The SISBIOTA-Diptera Brazilian Network: A long-term survey of Diptera from unexplored Brazilian Western Arc of Amazon, Cerrado, and Pantanal

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

Lupus retinopathy: epidemiology and risk factors / Retinopatia lúpica: epidemiologia e fatores de risco

ABSTRACT Lupus retinopathy is a clinical manifestation of systemic lupus erythematosus in the visual system. It is generally asymptomatic; however, it can become a threatening condition. It is closely associated with the inflammatory activity and higher mortality of systemic lupus erythematosus. Lupus retinopathy has several different clinical presentations, such as lupus microangiopathy, vascular occlusion, vasculitis, hypertensive retinopathy associated with lupus nephritis, and autoimmune retinopathy. Although the prevalence and associated factors of lupus retinopathy have been well defined in some parts of the world, there are no data from Latin America, including Brazil. As lupus retinopathy is generally asymptomatic, without a routine fundoscopy, it has been probably underestimated. This review is intended to discuss the epidemiology and risk factors of lupus retinopathy.

RESUMO A retinopatia lúpica é uma manifestação clínica do lúpus eritematoso sistêmico no sistema visual. Geralmente assintomática, porém pode ser uma condição ameaçadora à visão. Está intimamente associada à atividade inflamatória do lúpus eritematoso sistêmico e ao aumento da mortalidade. A retinopatia lúpica tem diversas apresentações clínicas, como a microangiopatia lúpica, oclusão vascular, vasculite, retinopatia hipertensiva associada à nefrite lúpica e retinopatia autoimune. A prevalência e os fatores associados à retinopatia lúpica estão bem definidos em algumas partes do mundo. No entanto, esses dados são pouco conhecidos na América Latina, incluindo o Brasil. Como a retinopatia lúpica é geralmente assintomática, sem a fundoscopia de rotina, provavelmente esta é subestimada. O objetivo desta revisão é discutir a epidemiologia e fatores de risco para retinopatia lúpica.

Manejo da coroidite interna punctata complicada por membrana neovascular sub-retiniana / Management of punctate inner choroidopathy complicated by subretinal neovascular membrane

RESUMO Este trabalho visou evidenciar a importância da detecção precoce da coroidite interna punctata e destacar sua fisiopatologia inflamatória e possíveis diagnósticos diferenciais dentro das white dot syndromes. O destaque foi dado principalmente à coroidite multifocal e à panuveíte, ao se demonstrar sua epidemiologia peculiar em mulheres jovens, caracterizar sua apresentação clínica típica na fundoscopia e explorar as vantagens e as desvantagens de realizar os exames complementares que fazem parte da análise multimodal útil para o diagnóstico (especialmente a angiografia fluoresceínica, a tomografia de coerência óptica e a indocianina verde). Descreve-se o caso de uma mulher de 28 anos diagnosticada com coroidite interna punctata com membrana neovascular coroidal em olho direito. O tratamento foi realizado com injeção intravítrea de aflibercepte e corticoterapia sistêmica 1mg/kg ao dia. Este relato é importante por permitir debater o manejo da coroidite interna punctata durante a gestação e a decisão de realizar o tratamento mediante uma diversidade de opções terapêuticas.

ABSTRACT This work aimed to demonstrate the importance of early detection of punctate inner choroidopathy, highlighting the pathophysiology of inflammation and the differential diagnoses among white dot syndromes. Special attention was given to multifocal choroiditis and panuveitis, by demonstrating the peculiar epidemiology in young women, characterizing the typical clinical presentation in ophthalmoscopy, and exploring the advantages and disadvantages of performing the complementary examinations, which are part of the multimodal analysis useful for diagnosis (particularly fluorescein angiography, optical coherence tomography, and indocyanine green). We report the case of a 28-year-old female, diagnosed as punctate inner choroidopathy with choroidal [N.T. no título aparece subretinal = subrretiniana] neovascular membrane in the right eye. She was treated with intravitreal injection of aflibercept and systemic corticosteroid 1 mg/kg/day. This case report is important for addressing the management of punctate inner choroidopathy during pregnancy, and the decision to carry out treatment considering diverse therapeutic options.

Arterite sifilítica / Retinal arteritis related to syphilis

Resumo Apresentamos um caso de neurosífilis em um homem jovem, com queixa de baixa acuidade visual (BAV) em olho esquerdo. Cursou com lesões eritemato-descamativas nas palmas das mãos, plantas dos pés e úlceras orais, sem lesões genitais. O exame oftalmológico revelou arterite em arcada nasal superior no olho afetado. Apresentou VDRL (1:4096) e FTA-Abs positivos. O exame do líquor cefalorraquidiano foi negativo. O tratamento foi realizado com ceftriaxona 2g/ dia por 14 dias, associado à prednisona 0,5mg/kg oral 48h após início do antibiótico. Após 15 dias de tratamento, houve melhora da AV, regressão da vasculite e redução da titulação do VDRL para 1:128.

Abstract We present a case of neurosyphilis in a young man with a complaint of low visual acuity in the left eye. He had erythematous-scaly lesions on the palms of the hands, soles of the feet and oral ulcers, without genital lesions. The ophthalmic examination revealed arteritis in the upper nasal arcade in the affected eye. He presented VDRL (1: 4096) and FTA-Abs positive. The cerebrospinal fluid cerebrospinal fluid test was negative. The treatment was performed with ceftriaxone 2g / day for 14 days, associated with prednisone 0.5mg / kg oral 48h after antibiotic onset. After 15 days of treatment, there was improvement of AV, regression of vasculitis and reduction of VDRL titration to 1: 128.

Preliminary observations on the patterns of co-occurrence of Black fly (Diptera: Simuliidae) larvae and some of their potential macroinvertebrate predators

ABSTRACT Biotic factors such as predation, although important drivers of the black fly community, are rarely investigated in the literature. This study aimed to test the hypothesis that the patterns of co-occurrence of black fly larvae and its potential predators is not random and that there is a correlation between its frequencies and Simuliidae larvae abundances. Larvae were sampled from two localities in the Pedra Branca State Park, Rio de Janeiro, Brazil, during the dry season in june 2018. We collected Simulium pertinax Kollar, 1832, Simulium subpallidum Lutz, 1910, Simulium (Inaequalium) sp., Simulium (Psaroniocompsa) sp. and Simulium (Trichodagmia) sp. The predators families present were Perlidae, Hydropsychidae, Leptoceridae, Libellulidae and Chironomidae. The null models showed that species co-occurred significantly more than expected by chance. The canonical correlation analyses for the Vargem Grande and Pau da Fome areas area showed a significant relationship between black fly abundances and predator abundances. In Vargem Grande the abundance of Chironomidae showed a highly significant positive correlation to S. (Psaroniocompsa) sp., while Hydropsychidae was significantly correlated to Simulium sp. On the other hand, in Pau da Fome Libellulidae was significantly correlated to S. (Psaroniocompsa) sp. and Simulium sp. and Chironomidae correlated significantly to Simulium sp. The result is consistent with what would be expected of organisms that exercise mutual population regulation, although other factors than biotic interactions may be causing these patterns. However the lack of mechanistic evidences on the effect of biotic interactions on black fly populations pose a challenge on the understanding of these patterns.

New synonymy to Simulium ( Inaequalium ) diversibranchium Lutz, with comments on the Inaequale species-group (Diptera, Simuliidae)

ABSTRACT Simulium (Inaequalium) Coscarón and Wygodzinsky, 1984 is a homogeneous subgenus widely spread on the Neotropical Region, which the adults can only be reliably identified from linked-reared specimens. Despite many revisionary works only a single character of the pupal gill separates Simulium diversibranchium Lutz, 1910 from S. mariavulcanoae Coscarón and Wygodzinsky, 1984. Specimens of both species show that S. mariavulcanoae is a junior synonym of S. diversibranchium. The relationship between S. diversibranchium and S. subnigrum Lutz, 1910 needs further investigation. Some features of the pupal gill often used as diagnosis in Simulium (Inaequalium) species, such as the direction of gill filaments or the height of the bifurcation of the secondary or tertiary branches of the pupal gill are highly polymorphic, making its use as diagnostic character not reliable.

Water pollution and distribution of the black fly (Diptera: Simuliidae) in the Atlantic Forest, Brazil / Contaminación del agua y distribución de la mosca negra (Díptera: Simuliidae) en el bosque Atlán&tico, Brasil

Abstract:Black flies have medical importance because some species are vectors of the Onchocerciasis and Mansonelosis, nevertheless, their ecology and potential use as bioindicators is still poorly studied in the Neotropical Region. In Brazil, bioindicators use is strongly focused in a multimetrical ecological index approach; this way, we investigated the black fly spatial distribution, in relation to abiotic factors correlated to water quality, to provide baseline information for their utilization as standalone indicators of lotic systems integrity. We have tested the hypothesis that environmental changes related to urbanization, lead to decreased abundance and loss in the number of species of the black fly fauna. The sampling was conducted in 10 urban and 10 preserved streams during the dry season (August-September) of 2012, in the mountainous region of Teresópolis, State of Rio de Janeiro, Brazil. The streams were characterized for their environmental integrity conditions and physico-chemical properties of water. In each stream, five different rapid points were sampled in a section of 50 meters, 10 meters apart from each other. The black flies were sampled with a kick-net sampler on rocky substrates. The material was separated and the larvae were sorted in morphotypes, and later, the final instar specimens were dissected and identified with the help of taxonomical literature at species level. A total abundance of 488 larvae from nine species were collected, 5 (1.02 %) in extremely impacted streams, 470 (96.31 %) in intermediate streams and 13 (2.66 %) in preserved streams. The visual evaluation (HII) differed in rela&tion to the water physico-chemical evaluation, in which more variation in the characterization of the sampling sites was observed. In Canonical Correspondence Analysis Simulium subpallidum, S. inscrustatumand S. pertinaxwere significantly associated with intermediate values of most of the variables, and then to intermediate impacted sites. On the other hand, Lutzsimulium hirticosta, S. subnigrumand Simuliumsp. A were associated to low values of chemical variables, and then to more preserved sites. Most studies on the bioindicator potential of Simuliidae have suggested an approach to agricultural impacts, while our results, on the other hand, showed that Simuliidae species were present in streams with intermediate urban pollution impacts, but absent in heavily impacted sites. Thus, our data suggested that some species are associated to more pristine breeding sites, such as L. hirticostaand Simuliumsp. A, while others may be good bioindicators of moderately impacted streams, such as S. pertinax, S. subnigrumand S. subpallidum.

Resumen:Aunque las moscas negras tienen importancia médica debido a que algunas de sus especies son vectores de la Oncocercosis y Mansonelosis, su ecología y su potencial como bioindicadores es aún poco estudiado en la Región Neotropical. En Brasil el uso de bioindicadores se centra principalmente en un índice ecológico multimétrico, en este estudio investigamos la distribución espacial de las moscas negras y su relación con los factores abióticos, para su utilización como indicadores de la integridad de los sis&temas lóticos. En este sentido, hemos probado la hipótesis de que los cambios ambientales relacionados con la urba&nización conducen a la disminución de la abundancia y la pérdida de especies de la mosca negra. El muestreo se llevó a cabo en la región montañosa del Estado de Río de Janei&ro, Brasil, en 10 zonas urbanas y 10 arroyos conservados durante la estación seca (agosto-septiembre) de 2012. Los arroyos se caracterizaron por sus condiciones de integridad del ambiente y las propiedades físico-químicas de agua. Las moscas negras se muestrearon en sustratos rocosos con un kick-net sampler.El material se separó y las larvas se ordenaron por morfotipos y más tarde los especímenes en último estadio se disectaron e identificaron con la ayuda de la literatura taxonómica a nivel de especie. Una abundancia total de 488 larvas de nueve especies fueron recolectadas, 5 (1.02 %) en arroyos muy afectados, 470 (96.31 %) en intermedios y 13 (2.66 %) en conservados. La evaluación visual (HII) difiere de la físico-química del agua, en la que se observó una mayor variación. En el Análisis Correspon&dencia Canónica, Simulium subpallidum, S. inscrustatumy S. pertinaxestaban asociadas significativamente con sitios de impacto intermedio, para la mayoría de las variables. Por otro lado, Lutzsimulium hirticosta, S. subnigrumy Simuliumsp. A se asocian con valores bajos de las varia&bles químicas, relacionado a sitios más conservados. La mayoría de los estudios sobre el potencial bioindicador de Simuliidae tienden a enfocarse en los impactos agrícolas, mientras que nuestros resultados, por otro lado, sugieren que las especies de Simuliidae están presentes en arroyos con impactos intermedios de contaminación urbana, pero ausentes en los sitios fuertemente afectados. Por lo tanto, nuestros datos sugieren que algunas especies tales como L. hirticostay Simuliumsp. A están asociadas a lugares de reproducción más prístinos, mientras que otras pueden ser bioindicadores de arroyos moderadamente afectados, como S. pertinax, S. subnigrumy S. subpallidum.

Evidence of phenotypic plasticity of larvae of Simulium subpallidum Lutz in different streams from the Brazilian Cerrado

In this paper, the overall morphological differences between populations of Simulium subpallidum Lutz, 1909 are studied. Several studies found in the literature point to a relationship between the labral fans and body size and the habitat where blackfly larvae occur. However, other characteristics potentially related to the microhabitat, such as abdominal hook circlet morphology, which is used for larvae to fix themselves in the substratum, and thoracic prolegs morphology, which help larvae move in the substratum, were analyzed in three different populations of S. subpallidum, one of which occupied a faster flow. The results suggest phenotypic plasticity in S. subpallidum and a tendency toward larger structures in faster flows.

Riscos de distúrbios osteomusculares em punhos de trabalhadores de uma indústria de pescados / Risks of musculoskeletal disorders in wrist for workers of a fish industry

INTRODUÇÃO: Os distúrbios osteomusculares relacionadas ao trabalho são patologias muito frequentes no meio industrial, principalmente quando os trabalhadores se encontram expostos a fatores de risco como, por exemplo, posturas inadequadas, repetitividade, uso de força excessiva e a exposição a vibrações. OBJETIVO: Avaliar o risco de distúrbios osteomusculares nos punhos de trabalhadores de uma indústria de pescados da cidade de Recife (PE). METODOLOGIA: Utilizou-se metodologia qualitativa baseada no método Strain Index (SI), o qual resulta em uma pontuação numérica que aponta a probabilidade de desenvolvimento de distúrbios osteomusculares no punho. O índice é baseado na pontuação do SI, representado pela interação multiplicativa entre as variáveis da tarefa: intensidade do esforço, duração do esforço, frequência do esforço, postura da mão e punho, ritmo de trabalho e duração diária da tarefa. RESULTADOS: O valor encontrado foi de SI = 9 para ambos os punhos, classificando-o como uma atividade com alto risco para o desenvolvimento de distúrbios osteomusculares nos punhos dos trabalhadores. CONCLUSÃO: A indicação da presença dos riscos desses distúrbios nos punhos durante a realização da atividade de trabalho foi determinada pela pontuação do SI, sugerindo a necessidade de intervenção ergonômica.

INTRODUCTION: Cumulative trauma disorders are very common diseases in industry, especially when workers are exposed to risk factors such as, for example, inappropriate postures, repetitive, excessive use of force and vibration exposure. OBJECTIVE: To assess the risk of musculoskeletal disorders in the wrists of industrial workers caught in the city of Recife, Pernambuco State, Brazil. METHODOLOGY: We used a qualitative methodology based on the method Strain Index (SI) which results in a numerical score that indicates the risk of developing musculoskeletal disorders in the wrist. The index is based on the SI score is represented by the multiplicative interaction between the task variables: intensity of exercise, exercise duration, frequency of stress, the hand and wrist posture, pace of work and daily duration of the task. RESULTS: The value found was SI = 9 for both fists, classifying it as a risky activity for the development of musculoskeletal disorders in the wrists of workers. CONCLUSION: The indication of the presence of the risks of these disorders in the wrists during the course of work activity was determined by the SI score, pointing to the need for ergonomic intervention.

Simulium (Chirostilbia) brunnescens (Diptera: Simuliidae) - new species from the Brazilian cerrado, Manso Dam, state of Mato Grosso, Brazil

A new species of Simuliidae, Simulium (Chirostilbia) brunnescens, was discovered at Chapada dos Guimarães, state of Mato Grosso, Brazil, and nearby municipalities (Paranatinga, Rosário do Oeste and Nobres). This species is described here based on the adults, pupae and larvae. This species is closely related to Simulium (C.) subpallidum Lutz, but could be differentiated in all stages: females, leg colour pattern and frontal dilatation size; males, gonostyle shape; pupae, number of gill filaments; larvae, body size and colour, postgenal cleft, ratio between antenna and stalk of labral fan.

Diversity and microdistribution of black fly (Diptera: Simuliidae) assemblages in the tropical savanna streams of the Brazilian cerrado

We describe the abiotic factors affecting the distribution of black flies at a microhabitat scale, rather than at the regional scale usually present in the literature on the Neotropics. Black fly larvae were sampled from the Tocantins River and three tributaries, located in the Brazilian savanna (state of Tocantins, Brazil) during six bi-monthly sampling periods from October 2004-August 2005. At each sampling site, 15 random quadrats (30 x 30 cm) were sampled each period and for each quadrat were determined mean water velocity, predominant substrate type (rocks, riffle litter or riparian vegetation) and depth detrended correspondence analysis (DCA) was used to determine associations with current velocity, whereas correspondence analysis (CA) was used to estimate site specific current velocity associations. Canonical correspondence analysis (CCA) was used to identify general microhabitat associations. The CCA showed that most species had a trend towards riffle litter, except for Simulium nigrimanum associated with rocky substrate and Simulium cuasiexiguum associated with riparian vegetation. The DCA showed a well defined pattern of water velocity associations. The CA revealed that the species showed different speed associations from one site to another, suggesting different competitive pressures resulting in the occurrence of different realized niches.

The phylogeny of Simulium (Chirostilbia) (Diptera: Simuliidae) and perspectives on the systematics of the genus in the Neotropical Region

Recently, knowledge of Neotropical Simuliidae has been accumulating quickly. However, information about supra-specific relationships is scarce and diagnoses of Simulium subgenera are unsatisfactory. To investigate the relationships among Simulium (Chirostilbia) species and test the subgenus monophyly, we performed a cladistic analysis. The ingroup included all species of this subgenus and the outgroup included representatives of the 17 species groups of Neotropical Simulium and three Holarctic species. The study was based on a data matrix with 31 terminal taxa and 45 morphological characteristics of adult, pupa and larva. The phylogenetic analysis under equal weights resulted in eight most-parsimonious trees (length = 178, consistency index = 34, retention index = 67). The monophyly of the S. (Chirostilbia) was not supported in our analysis. The Simulium subpallidum species group was closer to Simulium (Psilopelmia) and Simulium (Ectemnaspis) than to the Simulium pertinax species group. Additionally, we describe the three-dimensional shape of the terminalia of male and female of Simulium (Chirostilbia) for the first time and provide comments about the taxonomic problems involving some species of the subgenus: Simulium acarayense, Simulium papaveroi, S. pertinax, Simulium serranum, Simulium striginotum and S. subpallidum.

Observation of predation of the giant fishing spider Ancylometes rufus (Walckenaer, 1837) (Araneae, Ctenidae) on Dendropsophus melanargyreus Cope, 1877 (Anura, Hylidae) / Observação de predação da aranha pescadora Ancylometes rufus (Walckenaer, 1837) (Araneae, Ctenidae) sobre Dendropsophus melanargyreus Cope, 1877 (Anura, Hylidae)

We report here an observation of predation of the giant spider Ancylometes rufus on the tree frog Dendropsophus melanargyreus in a southern region of Amazonia Forest. We also reviewed the available literature on predation of this spider species on vertebrates.

Análise da carga de trabalho de analistas de sistemas e dos distúrbios osteomusculares / Analysis of the workload of systems analysts and musculoskeletal disorders

O objetivo desta pesquisa foi realizar avaliação das condições ergonômicas de analistas de sistemas, com a finalidade de conhecer os fatores geradores de sobrecargas físicas e cognitivas, suas repercussões sobre os trabalhadores e propor melhorias para a diminuição dessas sobrecargas. Metodologia:Foram utilizados o método SHTM (sistema homem-tarefa-máquina) de avaliação ergonômica; o diagramade Corlett, para a avaliação do desconforto corporal; o questionário de avaliação do mobiliário; e o NASATLX,para a avaliação de carga mental de trabalho. Resultados: Foram encontradas as prevalências de dorna coluna lombar (71%) e na coluna cervical (64%) dos entrevistados. Após a avaliação da carga mental de trabalho, foi observado que a demanda mental foi a mais exigida entre os analistas de sistemas e a média da carga global foi de 13,23. Conclusão: Pode-se concluir que a alta prevalência de dor musculoesquelética pode ser causada pela presença de mobiliário inadequado, pela adoção de posturas incorretas e pela alta exigência mental das atividades desenvolvidas.

OBJECTIVE: The purpose of this research was to conduct assessment of ergonomic conditions of systems analysts in order to understand the factors causing physical and cognitive overload, its implications for workers and propose improvements to reduce these physical and cognitive overload.METHODOLOGY: The SHTM (human-machine-task) method was used for ergonomic evaluation, the Corlett diagram for evaluation of bodily discomfort, questionnaire evaluation of the furniture and the NASA-TLX to assess mental workload. RESULTS: It was found a prevalence of pain in the lumbar spine of 71% and 64% of respondents in the cervical spine. After evaluation of mental workload, it was observed that the mental demand was most required among systems analysts and the average loading rate was of 13.23. CONCLUSION: It can be concluded that the high prevalence of musculoskeletal pain may be caused by the presence of inappropriate furniture, adoption of incorrect postures and high mental demand of the developed activities performed by systems analysts.

Caracterização das práticas de educação em saúde desenvolvidas por enfermeiros em um município do centro - oeste mineiro / Characterizing health education practices undertaken by nurses in a middle west city of the state of Minas Gerais / Caracterización de las prácticas de educación en salud llevadas a cabo porenfermeros de un municipio del centro - oeste de Minas Gerais

O objetivo com este trabalho é caracterizar as práticas de educação em saúde desenvolvidas por enfermeiros em um município do centro-oeste do Estado de Minas Gerais com população de aproximadamente 12.292 habitantes.Procedeu-se à investigação com a realização de entrevista semi estruturada por meio de formulários, da observação de atividades de grupo e da caracterização dos serviços realizados pelos quatro enfermeiros atuantes nas unidades básicas de saúde do município, bem como do coordenador da atenção primária municipal. Mediante uma abordagem qualitativa, peça fundamental para este estudo, as observações dos entrevistados sobre educação em saúde foram colhidas e analisadas. A pesquisa evidenciou como principais obstáculos existentes para a realização da atividade educativa a falta de capacitação técnico-político-pedagógica dos profissionais e gestores para com a saúde, bem como a limitação e/ou ausência de material pedagógico como suporte para as ações educativas. Foi possível observar que esses empecilhos, somados à prevalência de utilização de metodologia em que se prioriza a pedagogia de transmissão, vêm comprometendo a realização plena das práticas de enfermagem e educação em saúde no município em questão.

This study aims to characterize health education practices undertaken by nurses in a Middle West municipal district of 12,292 inhabitants in the State of Minas Gerais. The research was performed filling up forms in semi-structure dinterviews, group activities, observation and characterization of services performed by four nurses in primary health units as well as the city’s primary health care coordinator. The peoples’ answers were collected and analyzed, according to a qualitative approach. The research pointed out the main obstacles to the achievement of the educational activities as the lack of professionals’ and managers’ technical and-political pedagogy regarding public health as well as the short age of pedagogical resources to back up educative measures. Such obstacles, along with the methodology used,are jeopardizing the fulfillment of nursing practice and health education in the referred municipal district.

La investigación se llevó a cabo con formularios en entrevistas semi estructuradas, observando las actividades grupales y caracterizando el trabajo de cuatro enfermeros en las unidades básicas de salud y del coordinador de la atención primaria en salud. Se recogieron y analizaron las respuestas de los entrevistados desde un enfoque cualitativo. La investigación señaló los principales obstáculos para laactividad educativa, falta de profesionales técnico-políticos y educativos y de gestores de la salud bien como el poco o escaso material didáctico para respaldar las actividades educativas. Se observó que estos impedimentos conjuntamente con la prevalencia del uso de una metodología que da prioridad a la pedagogía de la transmisión, está poniendo enpeligro la realización de la práctica de enfermería y educación sanitaria en el municipio en cuestión.

Local distribution of blackfly (Diptera, Simuliidae) larvae in two adjacent streams: the role of water current velocity in the diversity of blackfly larvae / Distribuição local de larvas de simulídeos (Diptera, Simuliidae) em dois rios adjacentes: O papel da velocidade da correnteza na diversidade de larvas de simulídeos

This study aimed to evaluate the influence of water velocity speed on the local distribution and taxocenosis structure of blackfly larvae. The larvae were collected from two adjacent streams located in the municipality of Angra dos Reis (RJ): Caputera River and one of its tributaries. Riffle litter patches were sampled randomly using a 30 x 30 cm quadrat. Four blackfly species were found: Simulium incrustatum s. l. Lutz, 1910; Simulium (Inaequalium) sp. ; Simulium pertinax s. l. Kollar, 1832 and Simulium subpallidum s. l. Lutz, 1909. Among these species, Simulium pertinax s. l. was clearly associated with higher water current speeds, while Simulium subpallidum s. l. showed association with lower water velocities, and Simulium (Inaequalium) sp. had a relatively constant distribution along the water current gradient.

Este estudo teve como objetivo avaliar, nos criadouros de simulídeos, a influência da velocidade da água sobre a ocorrência de suas larvas e estrutura de suas taxocenoses. Para obtenção da amostragem foram utilizados "quadrats" de madeira distribuídos aleatoriamente no rio Caputera e um de seus tributários. Foram encontradas quatro espécies: Simulium incrustatum sl. Lutz, 1910; Simulium (Inaequalium) sp. ; Simulium pertinax sl. Kollar, 1832 e Simulium subpallidum sl. Lutz 1909. S. (Inaequalium) sp. teve uma distribuição quase constante ao longo do gradiente de correnteza. S. pertinax se mostrou fortemente associada às velocidades mais altas de correnteza, enquanto que S. subpallidum se mostrou associado às velocidades mais baixas.

Spatial and temporal distribution of blackflies (Diptera: Simuliidae) in the Itatiaia National Park, Brazil

The distribution of the blackfly larval taxocenoses of different altitudes in the Itatiaia National Park (located in the southeast of Rio de Janeiro state, Brazil 44°34' - 44°42' W , 22°16' - 22°28' S) was investigated on four campaigns, one in each season of 2003. On each campaign 60 samples were collected, using 30 x 30 cm wooden quadrats, distributed at four sites: Taquaral, Véu da Noiva, Três Picos and Brejo da Lapa. The winter and spring campaigns included two additional sampling sites: Alsene and Agulhas Negras. A total of 3578 larvae and 292 pupae were sampled, representative of six species: Simulium clavibranchium Lutz, S. subnigrum Lutz, S. rappae Py-Daniel, S. incrustatum Lutz, S. stellatum Gil-Azevedo, Figueiró & Maia-Herzog and Lutzsimulium pernigrum Lutz 1910. The highest larvae abundance and diversity were reported at the intermediate altitude site, Brejo da Lapa. Principal Components Analysis (PCA) revealed that L. pernigrum, S. stellatum and S. incrustatum were associated with the smaller breeding sites, the first two species being associated with sunny sites, while S. incrustatum occurred in sites with little sunlight.

A distribuição das taxocenoses de larvas de simulídeos (Diptera: Simuliidae) de diferentes altitudes no Parque Nacional de Itatiaia ( localizado no sudeste do estado do Rio de Janeiro, Brasil 44°34' - 44°42' W , 22°16' - 22°28' S ) foi investigada ao longo de quatro campanhas, cada uma em uma diferente estação do ano de 2003. Cada campanha foi composta de 60 amostras, obtidas a partir de "quadrats" de madeira de 30 x 30 cm, distribuídos através de quatro áreas: Taquaral, Véu da Noiva, Três Picos e Brejo da Lapa. Nas campanhas do inverno e da primavera, dois outros sítios, Alsene e Agulhas Negras, foram adicionados. Foram coletadas 3578 larvas e 292 pupas, sendo identificadas seis espécies: Simulium clavibranchium Lutz, S. subnigrum Lutz, S. rappae Py-Daniel, S. incrustatum Lutz, S. stellatum Gil-Azevedo, Figueiró & Maia-Herzog e Lutzsimulium pernigrum Lutz. As maiores abundância e diversidade foram encontradas no sítio de altura intermediária, o Brejo da Lapa. A análise de componentes principais (PCA) revelou que L. pernigrum, S. stellatum e S. incrustatum se mostraram associadas a rios de menor porte, com as duas primeiras espécies associadas a sítios com maior insolação e S. incrustatum com pouca insolação.

Caracteres diagnósticos de Simulium (Chirostilbia) pertinax Kollar (Diptera: Simuliidae) / Diagnostic Caracteres of Simulium (Chirostilbia) pertinax Kollar (Diptera: Simuliidae)

Este estudo teve por objetivo verificar padrões morfológicos que proporcionassem o correto diagnóstico de Simulium (Chirostilbia) pertinax Kollar. A análise morfológica de fêmeas e pupas permitiu encontrar estruturas bem características e de fácil utilização para identificação da espécie. Alguns caracteres diagnósticos (coloração do escudo, área nudiocular e paraprocto) podem apresentar pequenas variações e outros são constantes (coloração das pernas, cibário, forquilha, filamentos branquiais e casulo).

This study had as objective to verify the morphologic patterns that provide a correct diagnosis of Simulium (Chirostilbia) pertinax Kollar. The analysis of female and pupa morphology allowed to find characteristic structures that could be easily used to identify the species.Some diagnostic characteres (shield coloration, nudiocular area and paraprocto) show small variations and other are constant (leg coloration, cibarium, fork, branchial filaments and cocoon).
