Diversity and Flight Patterns of Caddisflies (Trichoptera) in an Atlantic Forest Fragment: Implications for Species Conservation in Threatened Ecosystems.

Anthropogenic activities have decimated the Atlantic Forest domain (AF) and increased the pressure on freshwater biota, such as Trichoptera, which is the most affected order by the current insect decline. Adult mobility is crucial for the colonisation of new environments unconnected by water sources. In this article, we describe the assemblage of caddisflies in a preserved AF fragment related to their functional feeding group and provide empirical data on the patterns of horizontal and vertical flight. Adults were collected using white sheet and light attraction traps, placed at different distances and heights from a stream in Pernambuco, Brazil. A total of 2934 specimens of 15 species from five families were collected, mostly collector-filterers. Horizontal flight was limited, with 80% of the abundance concentrated up to 20 m. Vertical stratification was also concentrated at lower heights. A female-biased proportion was observed at higher strata. The richness and abundance of species decreased with increasing distances and heights from the stream. Overall, Chimarra sp. and Macrostemum scharfi were the dominant species. Trichoptera is a key taxon used as a biological indicator of water quality, and here, knowledge on the diversity and flight patterns of adults is expanded. At the risk of intensive pollution of rivers in Atlantic forests, data on the adult dispersal can be incorporated in the assessment of endangerment status and in conservation strategies.

Bionomics, reproductive traits and assessment of forensic relevance of Peckia (Peckia) chrysostoma (Wiedemann, 1830) (Diptera: Sarcophagidae).

Peckia (Peckia) chrysostoma (Wiedemann, 1830) (Diptera: Sarcophagidae) is a colonizer of cadavers in the Neotropical Region. Nevertheless, data on development for the P. (P.) chrysostoma (e.g., instar duration) and behavioral strategies used by the species for locating and colonizing a corpse are scant. We aimed to explore bionomic and reproductive aspects of the flesh fly P. (P.) chrysostoma, and in this article we: (a) provide quantitative data on the life cycle of P. (P.) chrysostoma; (b) present bionomic measurements (length and weight) of larvae and pupae; (c) describe intrauterine egg and larvae development; and (d) analyze the ovo/larviposition behavior by gravid females. Females showed ovaries with discernible eggs and larvae between 8 and 10 days (x̅ = 23.3 eggs/female). This study reports the first observation of egg deposition, an atypical behavior for the species. The average development time for immature stages was 22.24 h and 21.36 h for 1st and 2nd respectively, and 3rd showed an average development time of 80.47 h. Pupa had the longest duration (x̅ = 295.69 h). A direct increase was observed in weight (P < 0.05) and length (P < 0.05) throughout time. The average survival time of males and females is approximately 30 days. This study expands the knowledge on P. (P.) chrysostoma, such as facultative ovoviviparity under laboratory conditions and the life cycle, which may benefit future studies for accuracy in entomology-based estimation of minimum post-mortem interval (min PMI).

Effects of Terbufos (Organophosphate) on Larval Behaviour of Two Forensically Important Diptera Species: Contributions for Entomotoxicology.

Neurotoxicant compounds interfere with the behaviour and biology of insects, significantly altering their locomotion patterns. However, little is known about the effect of organophosphates, neurotoxicants for agricultural, domestic and industrial use, on the larval movement of necrophagous flies, although being responsible for frequent cases of poisoning and accidental or intentional deaths. Thus, we aimed to study the influence of Terbufos (organophosphate) on the activity and mobility patterns of Lucilia eximia (Wiedemann 1819) (Calliphoridae) and Peckia (Peckia) chrysostoma (Wiedemann 1830) (Sarcophagidae) immatures collected from rat carcasses intoxicated with 5, 10 or 20 mg/kg of Terbufos, to evaluate (i) peristaltic movements and body contractions, and (ii) distance and shape of the trajectory travelled by the larva. Behavioural parameters were analysed in loco and through videos. We observed that the presence of Terbufos altered poisoned larvae's activity and body mobility in both taxon and dose-dependent manner. Lucilia eximia larvae were more active, with greater frequency of body movements and lateral contractions when intoxicated with high and intermediate doses of Terbufos. On the other hand, P. (P.) chrysostoma immatures were less active, with fewer body and lateral contractions when intoxicated with the high dose of the compound. This work experimentally demonstrates that the presence of Terbufos can alters the mobility and movement of intoxicated necrophagous Diptera, essential components of the cadaveric fauna.

Forensic entomology in research and practice: an overview of forensic experts' perceptions and scientific output in Brazil.

Given the growing demands for standardization of procedures for collection, preservation, and identification of insect specimens, this study aimed to identify how forensic entomology is used in Brazil and the perceptions of professionals involved in this process. We conducted: (1) bibliometric survey of the scientific production of forensic specialists from 2001 to 2020; (2) questionnaire applied to forensic professionals to verify their perceptions about the use of entomological evidence in practice. An increase in publications on Forensic Entomology was noticed in the last 5 years, mainly in the South and Northeast regions. Of the 82 respondents to the questionnaire, 62.8% deal with cadavers at least once a week, but 89.0% of the professionals who examine cadavers weekly find less than 10.0% colonized by insect larvae. Using entomological evidence to estimate PMI was mentioned by only 36.6% of the professionals. Most respondents stated no procedures related to collecting, handling, or identifying necrophagous insects in their daily practice. Regarding the chain of custody, 64.6% said they were aware of the changes in the regulations involving the collection and maintenance of forensic evidence. We emphasize the importance of collaboration between scientists at universities and crime scene examiners. Although the use of entomological evidence in criminal investigations in Brazil is still scarce, a growing interest in this area can be detected among forensic experts.

Behavioural Aspects of the Prey-Predator Interaction Among Necrophagous Diptera: Implications for Cadaveric Colonization.

Predation is a major process in determining the composition and dynamics of necrophagous dipteran assemblages and has implications for the colonization of cadavers. This work describes behavioural interactions between necrophagous larvae under a predator-prey perspective, using as a model the predatory species Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae) and three species of prey: Lucilia eximia (Wiedemann) (Calliphoridae), Synthesiomyia nudiseta (Wulp) (Muscidae) and Peckia (Peckia) chrysostoma (Wiedemann) (Sarcophagidae). Using experimental arenas, we observed behavioural acts, such as escape, avoidance and prey discrimination in three experiments, which also incorporated predator density. We demonstrate that the number of escapes, avoidance and predation varies according to the type of prey. Lucilia eximia and P. chrysostoma are able to avoid and/or escape the predator more frequently when compared to S. nudiseta. At least 70% of larvae of both species successfully evaded from C. albiceps attack. Low frequency of escape, associated with strong ability to counterattack, was observed for S. nudiseta. Peckia chrysostoma and L. eximia were the preferred items in the experiment of prey discrimination in both 2- and 3-choice tests. Predation occurs quickly, and the minimum predation time varied according to the prey species and predator density. Remarkably, prey handling varied with the species: whilst individual larvae chased and killed L. eximia, 75% of predation of P. chrysostoma occurred in groups of two or more C. albiceps larvae. Differential intraguild predation has implications for reducing populations of carrion insects-consequently affecting the likelihood of sampling necrophagous larvae in human cadavers.

Aspects of the reproductive behaviour and development of two forensically relevant species, Blaesoxipha (Gigantotheca) stallengi (Lahille, 1907) and Sarcophaga (Liopygia) ruficornis (Fabricius, 1794) (Diptera: Sarcophagidae)

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.

Development and Field Evaluation of a Novel, Inexpensive Passive Trap for Monitoring Dispersal of Necrophagous Dipteran Larvae.

Techniques for the survey of necrophagous dipterans are frequently designed for adult flies and often neglect forensically important information, such as the postfeeding larval dispersal following carcass colonization. In this study, we propose and test a novel trap design for the collection of dipteran larvae at the postfeeding stage. The Trap for Dispersing Larvae (TDL) consists of two semiindependent parts: 1) a 2-liter PET bottle, containing the attractant (carcass); and 2) a plastic box, which selectively captures postfeeding dispersing larvae. Based on a field test in a dry forest fragment in Brazil, the TDL trap captured ca. 1,500 larvae of 13 species of Calliphoridae, Muscidae, Fanniidae, and Sarcophagidae. The species richness of dispersing larvae recorded in our study was ca. 60% of that previously recorded in this area. As the TDL trap can assess larval dispersal without interfering with carcass decomposition, we demonstrate that it can be used to assess temporal variation in the dynamics of colonization. In the present study, most larval dispersal occurred at 5-d postexposure, but the traps remained efficient until 7 d, by which time rat carcasses had skeletonized. We conclude that the TDL trap captures the dispersing dipteran larvae with little interference in carcass decomposition processes. The trap also provides a representative sample of species and is simple to use and of low cost.

Diel Activity and Effect of Carcass Decomposition on the Attractiveness to the Forensically Important Species Oxelytrum Discicolle (Coleoptera: Silphidae)†.

Oxelytrum discicolle is a carrion beetle commonly found in the Neotropical region, mainly associated with cadavers and carcasses. Information on behavior related to the likelihood of cadaver colonization is scarce. We performed two field experiments in peri-urban forest in Brazil in order to strengthen our knowledge on O. discicolle behavior. In the first experiment, we assessed the preference for piglet carcasses at different stages of decomposition offered simultaneously in two seasons, dry and rainy, while in the second experiment we investigated the diel activity of adults. A total of 493 adults were collected in the experiments. A significantly higher abundance was detected in the rainy season. There was a marked preference for carcasses at advanced stages. Adults exhibited a typical nocturnal behavior, the number trapped at night was 17 times greater than those collected during the day. Oxelytrum discicolle is nocturnal species that prefers carcasses in advanced stage of decomposition.

Diversity of Sarcosaprophagous Calyptratae (Diptera) on Sandy Beaches Exposed to Increasing Levels of Urbanization in Brazil.

Sandy beaches are among the most impacted ecosystems worldwide, and the effects of urbanization on the biodiversity of these habitats are largely unknown, particularly in Brazil. We investigated the composition and structure of assemblages of sarcosaprophagous insects (Diptera: Calliphoridae, Sarcophagidae, and Muscidae) on six sandy beaches exposed to differential levels of human impact in Pernambuco State, Brazil. In total, 20,672 adults of 40 species were collected, of which 70% were Calliphoridae. Sarcophagidae had the highest diversity with 26 species of nine genera. A strong overlap in the composition of the assemblages across the six beaches was observed, with only a few species being restricted to one type of beach. The flesh flies Dexosarcophaga carvalhoi (Lopes), Peckia intermutans (Walker), and Titanogrypa larvicida (Lopes) occurred exclusively in beaches under low anthropogenic impact. Species with strong medical and veterinary importance such as Synthesiomyia nudiseta (Wulp) occurred even in beaches under low human presence. The invasive species Chrysomya albiceps (Wiedemann) and Chrysomya megacephala (F.) (Calliphoridae) were dominant in all beaches, which exposes the vulnerability of sandy beaches to exotic species. Our data imply that sarcosaprophagous flies can be used as early biological indicators to suggest urbanization in coastal environments.

Multiple colonization of a cadaver by insects in an indoor environment: first record of Fannia trimaculata (Diptera: Fanniidae) and Peckia (Peckia) chrysostoma (Sarcophagidae) as colonizers of a human corpse.

We describe here a case of multiple colonization of a male cadaver found indoors in the municipality of Jaboatao dos Guararapes, Brazil. The body was colonized by six species of Diptera: Chrysomya albiceps, Chrysomya megacephala, Chrysomya putoria (Calliphoridae), Megaselia scalaris (Phoridae), Fannia trimaculata (Fanniidae), and Peckia (Peckia) chrysostoma (Sarcophagidae). The most abundant species were C. albiceps (65.0 % of all emerged adults) and C. megacephala (18.6 %). The case illustrates the ability of six insect species to simultaneously colonize a corpse in an indoor environment and represents the first collaboration between the forensic police and entomologists in Northeastern Brazil. We provide here the first record of two species, F. trimaculata and Peckia (P.) chrysostoma colonizing a human cadaver. We also report the first case of cadaver colonization by C. putoria and M. scalaris in Northeastern Brazil. Information on the development time of two species, C. albiceps and C. megacephala, were used to discuss the estimation of the post-mortem interval. Considering that the region harbors the highest rates of homicide in Brazil, implications of these findings for the consolidation of forensic entomology in the region are discussed.

Insects (Diptera) associated with cadavers at the Institute of Legal Medicine in Pernambuco, Brazil: implications for forensic entomology.

Increasing rates of unsolved homicides in Brazil prompt the need for applied entomological data to be used as a complementary tool by criminal investigators. In that context, we analyzed the occurrence of forensically important insect species (Order Diptera) on 14 cadavers taken into the Institute of Legal Medicine (ILM), in Pernambuco, Brazil, according to the conditions of the body and the pattern of colonisation by insects. Simultaneously, we surveyed the diversity of insects in the surrounding environment using bait traps. Five species were present on cadavers: Chrysomya albiceps, Chrysomya megacephala and Cochliomyia macellaria (Calliphoridae), Oxysarcodexia riograndensis and Ravinia belforti (Sarcophagidae). A total of 4689 adult insects belonging to 24 species of seven dipteran families (Calliphoridae, Sarcophagidae, Muscidae, Fanniidae, Phoridae, Anthomyiidae and Stratiomyidae) was collected at the ILM premises. C. albiceps was the most frequent species on the corpses and the most abundant in the traps. Species referred to as of forensic importance, such as Lucilia eximia, Chrysomya putoria, Oxysarcodexia modesta and Ophyra chalcogaster were collected on traps, but not on cadavers. There seems to be a limited colonisation of cadavers at the scene of the death, despite the ubiquity of necrophagous species in the area. The results contribute to differentiate between species that are involved in decomposition and those found in and around the mortuary installations of the ILM, thus providing potential clues about the locality of death and the post-mortem interval.

Scorpion fauna of the island of Fernando de Noronha, Brazil: first record of Tityus stigmurus (Thorell 1877) (Arachnida, Buthidae) / Escorpiofauna da ilha de Fernando de Noronha, Brasil: primeiro registro de Tityus stigmurus (Thorell, 1877) (Arachnida, Buthidae)

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.

Percepção sobre distúrbios de saúde entre trabalhadores expostos a música eletronicamente amplificada em danceterias de Recife / Perception about health disorders among workers exposed to electronically amplified music in nightclubs in Recife

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.

An ecoregional classification for the state of Roraima, Brazil: the importance of landscape in malaria biology.

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.

Distribution summaries of malaria vectors in the northern Brazilian Amazon.

Knowledge of vector distribution is important for the design of effective local malaria control programs. Here we apply ecological niche modeling to analyze and predict the distributions of malaria vectors based on entomological collection points in the State of Roraima in the northern Brazilian Amazon Basin. Anopheline collections were conducted from 1999 to 2003 at 76 localities, all with active malaria transmission. A total of 13 anopheline species was identified from 17,074 adult females collected: Anopheles darlingi, An. albitarsis s.l., An. nuneztovari, An. triannulatus s.l., An. braziliensis, An. peryassui, An. oswaldoi s.l., An. mattogrossensis, An. strodei, An. evansae, An. squamifemur, An. mediopunctatus s.l, An. intermedius. Anopheles darlingi, and An. albitarsis were the most frequently found species. An. squamifemur was found for the first time in Roraima. A distributional prediction model (genetic algorithm for rule-set prediction-GARP) and environmental variables were used to predicted potential distribution range for six anopheline species that occurred at > or = 19 collection points. The method allows for the application of moderate sample sizes to produce distribution maps of vector species that could be used to maximize efficiency of surveys and optimize use of economic resources in epidemiology and control.

Acidentes por aranhas, insetos e centopéias registrados no Centro de Assistência Toxicológica de Pernambuco (1993 a 2003) / Accidents by spiders, insects and centipedes notified by the Centro de Assistência Toxicológica de Pernambuco (1993 to 2003)

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.

Biossegurança em laboratórios universitários: um estudo de caso na Universidade Federal de Pernambuco / Biosafety in university laboratories: a case study at the Universidade Federal de Pernambuco

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.
