ABSTRACT

Abstract We studied aspects of the reproductive behaviour and development of two species of Sarcophagidae (Diptera) of potential forensic importance, Blaesoxipha stallengi (Lahille, 1907) and Sarcophaga ruficornis (Fabricius, 1794), which are dominant in assemblages in dry forests in Northeastern Brazil. We described the behavioural acts associated with courtship and mating and estimated the development time (from egg/larva until adult) - of both species. Description of the reproductive behaviour was based on 50 couples of each species whereas 250 larvae were used for the estimation of the developmental time. A total of 55 successful copula were observed for B. stallengi and 142 for S. ruficornis. Pre-copulatory behaviour differed between the species, as S. ruficornis presented a high rate of competition among male specimens. Blaesoxipha stallengi copulated more frequently in the morning and the mean duration of copulation was similar for both species. The species showed different reproductive strategies: S. ruficornis follows the typical strategy in Sarcophagidae and are viviparous (larviparity), but we report here the first documented evidence of ovoviviparity of B. stallengi. Sex ratio of the emerged adults did not differ (p > 0.05) markedly for either species. Total development time in days was similar with 22.9 for B. stallengi and 21.3 for S. ruficornis. The pronounced similarities in the morphology of both species - combined with their similar time of development - may act as confounding factors for forensic entomologists and stress out the need for an accurate taxonomical identification.

ABSTRACT

A survey of the scorpion fauna of the Island of Fernando de Noronha, Pernambuco (Brazil), was carried out in October 2005. Methods included active collecting and pitfall traps in several areas of the island under different degrees of human-caused alteration. Forty four scorpions, belonging to two species were collected: Isometrus maculatus (DeGeer, 1778), previously listed for the Island, and Tityus stigmurus (Thorell, 1877), here recorded for the first time. This species was probably introduced via cargo shipments from the continent and offers risk to the local population due to the gravity of the accidents.


Foi conduzido um levantamento sobre a escorpiofauna de Fernando de Noronha, Pernambuco (Brasil), em outubro de 2005. Os métodos incluíram coleta ativa e armadilhas de queda em várias regiões da ilha, sob diferentes graus de alteração antrópica. Foram coletados 44 escorpiões de duas espécies: Isometrus maculatus (DeGeer, 1778), previamente listada para a ilha, e Tityus stigmurus (Thorell, 1877), registrada pela primeira vez. Trata-se de uma espécie provavelmente introduzida através do tráfego de material do continente, e que oferece risco à população local, devido à gravidade dos acidentes.

ABSTRACT

Este trabalho visou a detectar problemas de saúde e analisar o nível de conhecimento e proteção contra os efeitos danosos da música eletronicamente amplificada (MEA) entre funcionários de danceterias de Recife. Entre março e julho de 2006, foram visitadas dez danceterias, sendo entrevistados 71 trabalhadores expostos diretamente ao barulho intenso, como seguranças, recepcionistas, garçons e caixas. Distúrbios do sono (insônia) foram citados por 33,8 por cento dos funcionários. Os problemas de saúde mais freqüentemente citados foram estresse (23,9 por cento), zumbido (22,5 por cento), sensaçãode eco (15,5 por cento) e dor de ouvido (5,6 por cento). Cerca de 75 por cento dos funcionários não utilizam proteção auditiva durante o trabalho. Esses dados sugerem que a exposição à MEA pode alterar a saúde dos trabalhadores e destacam a necessidade de maior conscientização entre funcionários e gerentes.

ABSTRACT

Understanding the different background landscapes in which malaria transmission occurs is fundamental to understanding malaria epidemiology and to designing effective local malaria control programs. Geology, geomorphology, vegetation, climate, land use, and anopheline distribution were used as a basis for an ecological classification of the state of Roraima, Brazil, in the northern Amazon Basin, focused on the natural history of malaria and transmission. We used unsupervised maximum likelihood classification, principal components analysis, and weighted overlay with equal contribution analyses to fine-scale thematic maps that resulted in clustered regions. We used ecological niche modeling techniques to develop a fine-scale picture of malaria vector distributions in the state. Eight ecoregions were identified and malaria-related aspects are discussed based on this classification, including 5 types of dense tropical rain forest and 3 types of savannah. Ecoregions formed by dense tropical rain forest were named as montane (ecoregion I), submontane (II), plateau (III), lowland (IV), and alluvial (V). Ecoregions formed by savannah were divided into steppe (VI, campos de Roraima), savannah (VII, cerrado), and wetland (VIII, campinarana). Such ecoregional mappings are important tools in integrated malaria control programs that aim to identify specific characteristics of malaria transmission, classify transmission risk, and define priority areas and appropriate interventions. For some areas, extension of these approaches to still-finer resolutions will provide an improved picture of malaria transmission patterns.

ABSTRACT

O conhecimento limitado e a benignidade clínica de acidentes envolvendo artrópodos contribuem para a subnotificação. Este estudo buscou inventariar os acidentes causados por artrópodos, excetuando-se os escorpiões, ocorridos em Pernambuco e registrados no Centro de Assistência Toxicológica (CEATOX-PE) entre 1993 a 2003. Foram analisados os seguintes aspectos: local do acidente, agente causal e distribuição sazonal. Dos 233 acidentes, 48,5por cento ocorreram na Região Metropolitana do Recife, excluindo-se a cidade do Recife. As notificações envolvendo abelhas foram as mais freqüentes, com 37,4por cento dos casos, seguidas de centopéias, com 18,9por cento. Percebe-se uma tendência de aumento no registro de casos ao longo dos anos. Não foram verificadas diferenças no índice de ocorrências entre a estação seca e a chuvosa. A ocupação desordenada de ambientes associada à sinantropia favorece o aumento dos acidentes em áreas urbanas. Os acidentados raramente levam o artrópodo para identificação e a subnotificação é marcante nos acidentes envolvendo os artrópodos estudados.

ABSTRACT

Embora seja uma das responsabilidades de um laboratório de ensino e pesquisa, a promoção da biossegurança como parte integrante da saúde ocupacional tem recebido limitada atenção em universidades brasileiras. Partindo desta necessidade, o presente trabalho analisou a adoção de procedimentos de proteção individual e coletiva nos sete laboratórios do Departamento de Micologia da UFPE através da aplicação de questionários junto aos responsáveis por cada um dos laboratórios, utilizando os critérios da CTNBio. Foram observadas algumas deficiências nos laboratórios, tais como ausência de extintores de incêndios, de protocolo de acidentes, chuveiros de emergência e limitada disponibilidade de avisos educativos para prevenção de acidentes. Por outro lado, detectou-se a preocupação com a correta armazenagem de produtos químicos e com a instalação elétrica/hidráulica dos laboratórios. Conclui-se que, de modo geral, a biossegurança é respeitada nos laboratórios analisados. Entretanto, é necessária uma maior conscientização dos usuários e uma inserção mais aprofundada do tema biossegurança nos cursos de Ciências Biológicas da UFPE.


Although biosafety is a major responsibility of research and teaching laboratories, its promotion as a component of occupational health has received limited attention in Brazilian universities. Due to this necessity, this study aimed to analyze the procedures for individual and collective protection at the seven laboratories of the Mycology Department at the UFPE, applying questionnaires based on CTNBio criteria to the laboratory coordinators. Some flaws were detected, such as the lack of fire extinguishers, accident protocol register, emergency showers, and scant warning and educational posters for accident prevention in the labs. On the other hand, the correct storage of chemicals and adequate electrical/ hydraulic facilities were observed. The overall biosafety procedures at the laboratories analyzed were adequate. However, a deeper user's awareness and a stronger integration of biosafety as a daily practice in Biology courses at the UFPE are needed.

ABSTRACT

Diseases caused by Leishmania parasites are relatively common in rural areas in Brazil. However, studies on eco-epidemiological aspects of the disease and its vectors, Lutzomyia species (Diptera: Psychodidae), are scarce. We studied the leishmaniasis incidence from January 1990 to December 1999 in the State of Pernambuco, Northeastern Brazil. Based on data collected by the Fundação Nacional de Saúde, the profile on infected people, in terms of age, sex and occupation was investigated. The physiogeographical aspects of disease incidence were also considered. A total of 7,616 cases were recorded, of which 82.8 percent were cutaneous and 17.2 percent were visceral leishmaniasis. A higher incidence of disease was observed among men, and areas with remnants of rainforest had higher rates of infection. Children and early teenagers had a higher percentage of infection, as had adults involved in agricultural activities. Changes in vegetation composition and abundance, associated with an adaptative behavior by female mosquito vectors, may have contributed to an increase of leishmaniasis incidence in urban areas.
