Resumen La entomotoxicología forense, que analiza insectos necrófagos para detectar sustancias tóxicas, es crucial en la determinación de causas de muerte y la estimación del intervalo post-mortem. Este estudio se centró en Peckia intermutans (Walker) (Diptera: Sarcophagidae) como marcador para la detección de metanol, un alcohol potencialmente letal presente como adulterante en bebidas alcohólicas debido a su bajo costo y parecido con el etanol. Se desarrolló un método de cromatografía de gases-espectrometría de masas (HS-GC-MS) para detectar metanol y se estudió su efecto sobre el tiempo de desarrollo, supervivencia y morfología de las moscas de la carne. Las larvas se criaron en sustratos de hígado enriquecidos con metanol (300, 500 y 1000 mg/kg). Los resultados mostraron: el método desarrollado detectó metanol en todos los estadios; el metanol afectó el tiempo de desarrollo de las moscas; la supervivencia aumentó con una mayor concentración de metanol; y los cambios morfológicos fueron evidentes en el peso. Este estudio ofrece valiosa información sobre la investigación entomotoxicológica del Ecuador, por lo que se debe considerar los cambios morfológicos de P. intermutans para evitar estimaciones inexactas de los intervalos post-mortem.

Abstract Forensic entomotoxicology, which analyzes necrophagous insects to detect toxic substances, is crucial in determining causes of death and estimating the post-mortem interval. This study focused on Peckia intermutans (Walker) (Diptera: Sarcophagidae) as a marker for detecting methanol, a potentially lethal alcohol often added as an adulterant in alcoholic beverages due to its low cost and similarity to ethanol. A gas chromatography-mass spectrometry (HS-GC-MS) method was developed to detect methanol, and its effects on the development time, survival, and morphology of flesh flies were investigated. Larvae were reared on liver substrates enriched with methanol (300, 500, and 1000 mg/kg). Results showed: the developed method detected methanol in all instars; methanol affected the developmental time of the flies; survival increased with higher methanol concentration; and morphological changes were evident in weight. This study provides valuable information on entomotoxicological research in Ecuador, emphasizing the need to consider morphological changes in P. intermutans to avoid inaccurate estimations of post-mortem intervals.

Resumen Los márgenes de las rutas que contienen vegetación natural brindan condiciones biológicas estables y promueven la biodiversidad. Estas áreas son importantes para mejorar los servicios ecosistémicos en los paisajes agrícolas. Los objetivos de este estudio fueron i) evaluar la diversidad de insectos como visitantes florales (excluyendo apiformes), y la riqueza de especies de plantas en los márgenes de las rutas, ii) determinar los Grupos Funcionales de insectos registrados como visitantes florales en los márgenes de rutas, y iii) analizar el rol ecológico de los insectos presentes en ocho márgenes de rutas ubicados en la región centro-este de la provincia de Santa Fe, Argentina. El estudio se realizó a lo largo de cuatro rutas provinciales (N°. 6, 10, 62 y 64) y la ruta nacional N°. 19; de noviembre de 2013 a septiembre de 2015. Se registraron un total de 1614 insectos, Oxysarcodexia varia (Walker) (Diptera: Sarcophagidae), Allograpta exotica (Wiedemann) (Diptera: Syrphidae) y Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), fueron las especies más abundantes. Las familias Brassicaceae, Apiaceae y Asteraceae recibieron el mayor número de visitas de insectos. Se registraron un total de 225 interacciones planta-insecto. Se discute la importancia de los márgenes de ruta con vegetación natural para proporcionar alimento y refugio a insectos polinizadores, depredadores, parasitoides, herbívoros y descomponedores.

ABSTRACT Sarcophagidae flies have great forensic importance, since different instars of their larval development are used in the determination of the postmortem interval (PMI) of corpses. However, for many species, intrapuparial developmental data are scarce. Here we analyzed the intrapuparial development of the sarcophagid Peckia pexata and describe the chronological and morphological changes that occur during metamorphosis. We reared approximately 330 specimens originating from the Colombian Amazon in the laboratory. Prepupae were identified by size reduction and coloration change. During the first five days of the study, four individuals were sampled every three hours, then every six hours until adult emergence. Specimens were fixed in 96% alcohol, then immersed in Carnoy solution for 24 hours and in formic acid (5%) for 48 hours for dissection and analysis of morphological changes. Four morphological phases of intrapuparial development of P. pexata were observed: 1) larva pupa apolysis, which lasted, in average, 9 h; 2) cryptocephalic pupa, 6 h; 3) phanerocephalic pupa, 6.5 h; and 4) pharate adult (transparent eyes, 48 h; yellow eyes, 216 h; pink eyes, 35 h; and red eyes, 52 h). The pharate adult was fully formed at 340 h and adult emergence occurred at 372.5 h or 15.5 days. We also described the formation of the prepupa, the pupariation and the final metamorphosis for the imago and compared it with the known events for Peckia intermutans, Peckia lambens (Sarcophagidae) and Lucilia eximia (Calliphoridae). importance PMI (PMI corpses However species scarce 33 laboratory change study 96 alcohol 2 5% 5 (5% 4 P observed 1 apolysis lasted average 3 65 6. transparent eyes 21 h. . h) 34 3725 372 372. 155 15 15. prepupa intermutans (Sarcophagidae Calliphoridae.

RESUMEN Las moscas Sarcophagidae tienen gran importancia forense, ya que diferentes etapas de su desarrollo larvario son utilizadas en la determinación del intervalo post mortem (IPM) de cadáveres. Sin embargo, para muchas especies los datos sobre el desarrollo intrapupal son escasos. Aquí analizamos el desarrollo intrapupal del sarcofagido Peckia pexata y describimos los cambios cronológicos y morfológicos que ocurren durante la metamorfosis. Criamos aproximadamente 330 especímenes originarios de la Amazonía colombiana en laboratorio. Prepupas se identificaron por la reducción de tamaño y cambio de color. Durante los primeros cinco días se tomaron muestras de cuatro individuos cada tres horas, y posteriormente cada seis horas hasta la emergencia de los adultos. Los especímenes se fijaron en alcohol al 96%, posteriormente se sumergieron en solución Carnoy durante 24 horas y en ácido fórmico (5%) durante 48 horas, para disección y el análisis de los cambios morfológicos. Observamos cuatro etapas del desarrollo intrapupal de P. pexata: 1) larva pupa apolisis, que duró, en promedio, 9 h; 2) pupa criptocefálica, 6 h; 3) pupa fanerocefálica, 6.5 h; y 4) adulto farado (ojos transparentes, 48 h; ojos amarillos, 216 h; ojos rosados, 35 h; y ojos rojos, 52 h). El adulto farado se formó completamente a las 340 h y la emergencia del adulto se produjo a las 372.5 h o 15,5 días. También describimos la formación de la prepupa, la pupariación y la metamorfosis final para el imago y lo comparamos con los eventos conocidos para Peckia intermutans, Peckia lambens (Sarcophagidae) y Lucilia eximia (Calliphoridae). forense IPM (IPM cadáveres embargo escasos 33 laboratorio color adultos 96 96% 2 5% 5 (5% 4 P 1 apolisis duró promedio criptocefálica 3 fanerocefálica 65 6. transparentes amarillos 21 rosados rojos h. . h) 34 3725 372 372. 155 15 15, prepupa intermutans (Sarcophagidae Calliphoridae.

Resumen: En | Texto: En | PDF: En

Abstract The Sarcophagidae family (Diptera) encompasses a group of flies of significant ecological importance. Additionally, numerous species within this family hold substantial value in the realms of medicine, veterinary and forensic science. The objective of this study was to conduct a comprehensive survey of Sarcophagidae species within transitional zones between the Caatinga and Cerrado biomes in the Northeastern region of Brazil. To achieve this, a total of 15 field expeditions were conducted across three distinct phytophysiognomies—riparian, vereda, and a segment of shrubby Caatinga—from 2019 to 2021. A total of 16 genera and 40 species were collected. Among them, a new species for science (Titanogrypa (Airypel) sp. nov.), Emblemasoma emblemasoma Dodge is newly recorded from South America/Brazil and the Caatinga biome, and three species constitute new records for the Northeast region (Dexosarcophaga patiuorum Santos, Pape & Mello-Patiu, Lepidodexia (Notochaeta) fumipennis (Lopes), and Oxysarcodexia meridionalis (Engel)). The most abundant species were Oxysarcodexia thornax (Walker), Oxysarcodexia avuncula (Lopes), and Argoravinia (Argoravinia) catiae Carvalho Filho & Esposito, collectively constituting 56.11% of the entire collected sample. The distribution of species across different vegetations was noted, with 19 species exclusive to riparian vegetation, three to vereda vegetation, and seven species unique to the Caatinga.

Resumen: En | Texto: En | PDF: En

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.

Abstract In this work, we report for the first time the occurrence of the parasitoid wasp Brachymeria amenocles (Walker, 1846) (Hymenoptera: Chalcididae) associated with the larvae of the flesh fly, Peckia (Peckia) chrysostoma (Wiedemann, 1830) (Diptera: Sarcophagidae), in Brazil. This parasitoid species was collected together with the species Brachymeria podagrica (Fabricius, 1787), in the municipality of Rio de Janeiro, geographically located in the Southeast region of Brazil, in larvae of the same host species reared in the same attraction substrate, behaving as solitary parasitoids. A trap containing putrefying sardine was exposed for 48 h, in the upper part of a house, located in Vila Isabel, an urban area. The larvae collected were reared in the laboratory without control of environmental conditions. A total of three adult parasitoid wasps of the species B. podagrica, and nine adult parasitoid wasps of the species B. amenocles emerged from 12 host pupae, resulting in a prevalence of parasitoidism of 4.8% and 14.5%, respectively. Developing parasitoids at the pupal phase were observed in another 34 host pupae dissected. work Walker, Walker (Walker 1846 Hymenoptera (Hymenoptera Chalcididae fly (Peckia Wiedemann, Wiedemann (Wiedemann 1830 Diptera (Diptera Sarcophagidae, Sarcophagidae , Sarcophagidae) Brazil Fabricius, Fabricius (Fabricius 1787, 1787 1787) Janeiro substrate 4 h house Isabel area conditions B 1 8 4.8 145 14 5 14.5% respectively 3 dissected 184 183 178 4. 14.5 18 17 14.

Resumen Sarcophagidae es una de las familias más grandes de Oestroidea. La familia se clasifica en tres subfamilias, Miltogramminae, Paramacronychiinae, y Sarcophaginae. El número de especies de Sarcophaginae reportadas para Colombia, así como su distribución geográfica, aún están pobremente documentadas. Aquí se registran seis especies por primera vez para el país: Argoravinia catiae Carvalho Filho & Esposito, Oxysarcodexia adunca Lopes, Oxysarcodexia carvalhoi Lopes, Oxysarcodexia eberti Lopes & Tibana, Peckia .Euboettcheria. epimelia (Lopes), and Peckia .Sarcodexia. chirotheca (Hall). Se amplía la ocurrencia de 16 especies previamente registradas en Colombia para los Departamentos de Amazonas, Antioquia, Chocó, Magdalena y Meta. Como resultado, el número de especies conocidas de Sarcophaginae para Colombia se actualiza a 109.

Abstract Sarcophagidae is one of the largest families of Oestroidea. The family is classified into three subfamilies, Miltogramminae, Paramacronychiinae, and Sarcophaginae. The number of species of Sarcophaginae occurring in Colombia, as well as their geographical distributions, are still poorly documented. Here, six species are recorded for the first time in the country: Argoravinia catiae Carvalho Filho & Esposito, Oxysarcodexia adunca Lopes, Oxysarcodexia carvalhoi Lopes, Oxysarcodexia eberti Lopes & Tibana, Peckia .Euboettcheria. epimelia (Lopes), and Peckia .Sarcodexia. chirotheca (Hall). The occurrence of 16 species previously registered in Colombia is expanded to the Departments of Amazonas, Antioquia, Chocó, Magdalena, and Meta. As a result, the number of known Sarcophaginae species for Colombia is updated to 109.

Abstract Despite being the most diverse family of flies found in carcasses and corps in the Neotropical Region, Sarcophagidae is still underestimated in Peru. This research was developed in the Department of Piura, Northern Peru and we identify the flesh flies captured on two kinds of animal carcasses: dog and guinea pigs. As a result, a new record was documented for Peru: Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830) and eight new records for the Department of Piura.

Resumo: As moscas Sarcophagidae podem ser encontradas em vários tipos de ambientes, naturais ou antropizados, desde florestas até desertos. O estado brasileiro do Maranhão, localizado na Região Nordeste, possui uma grande variedade de áreas fitogeográficas, mas poucos estudos faunísticos tem sido realizados nesta região. Portanto, o objetivo deste estudo foi inventariar as espécies de sarcofagídeos e comparar os seus padrões de abundância entre as áreas de cerrado (vegetação tipo savana) e de mata ciliar do município de Codó, estado do Maranhão. Foram realizadas 12 coletas, do segundo semestre de 2015 ao primeiro semestre de 2017. Foram coletados 3.220 espécimes, dos quais 27,15% são machos, representados por nove gêneros e 27 espécies. No cerrado foram coletados 491 espécimes (16 espécies), na mata ciliar foram coletados 383 espécimes (21 espécies). As espécies mais abundantes foram Peckia (Sarcodexia) lambens (Wiedemann) (56,18% dos indivíduos amostrados), Peckia (Peckia) pexata (Wulp) (13%), Peckia (Euboettcheria) collusor (Curran & Walley) (13%) e Peckia (Peckia) chrysostoma Wiedemann (10%). Apenas P. (E.) collusor foi significativamente mais abundante na área de cerrado. Oxysarcodexia angrensis (Lopes), Peckia (Peckia) enderleini (Engel) e Retrocitomiya andina Lopes são novos registros para a Região Nordeste do Brasil e Titanogrypa (Cuculomyia) albuquerquei (Lopes) é novo registro para o estado do Maranhão.

Abstract: Flesh flies (Sarcophagidae) have been found in a wide range of natural and anthropogenic environments, from forests to deserts. The state of Maranhão, located in Northeastern Brazil, has a diverse phytogeography, but few faunistic studies have been conducted in this area. Therefore, the objective of this study was to inventory species of Sarcophagidae and compare abundance patterns between the Cerrado (savanna-like vegetation) and riparian forests in the municipality of Codó, state of Maranhão. Twelve sampling events were carried out from the second half of 2015 to the first half of 2017. This resulted in 3,220 specimens, 27.15% of which were males, from nine genera and 27 species. A total of 491 specimens (16 species) were collected in the Cerrado, and 383 specimens (21 species) in the riparian forest. Peckia (Sarcodexia) lambens (Wiedemann) was the most abundant species (56,18% of the specimens sampled), followed by Peckia (Peckia) pexata (Wulp) (13%); Peckia (Euboettcheria) collusor (Curran & Walley) (13%), and Peckia (Peckia) chrysostoma Wiedemann (10%). Only P. (E.) collusor was found in greater abundance in the Cerrado. Oxysarcodexia angrensis (Lopes), Peckia (Peckia) enderleini (Engel), and Retrocitomiya andina Lopes are all new records to Maranhão and the entire Northeast Region of Brazil. Titanogrypa (Cuculomyia) albuquerquei (Lopes) is also a new to Maranhão.

Resumo: O presente estudo teve como objetivo documentar a composição, abundância e riqueza das espécies de moscas saprófitas (Mesembrinellidae, Neriidae, Ropalomeridae e Sarcophagidae) da Volta Grande do rio Xingu, uma área pouco amostrada e impactada pela Hidrelétrica Belo Monte. Foram realizadas cinco expedições de coleta entre 2014 a 2016, quando foram utilizadas armadilhas contendo banana em fermentação como isca. Foram coletados 154 espécimes, três gêneros e seis espécies de Mesembrinellidae; 196 espécimes, três gêneros e sete espécies de Neriidae; 272 espécimes, três gêneros e seis espécies de Ropalomeridae; e 624 espécimes, 22 espécies e 10 gêneros de Sarcophagidae. As curvas de acumulo de espécies para todas as famílias, exceto Sarcophagidae, demonstraram uma forte tendência à estabilização, mostrando que o esforço amostral foi suficiente para registrar a maioria das espécies-alvo. Laneela perisi (Mariluis, 1987) (Mesembrinellidae) é um novo registro para o estado do Pará. Entre os Ropalomeridae, Apophorhynchus amazonensisPrado, 1966, é um novo registro para o Pará. Em relação aos Sarcophagidae, Helicobia aurescens (Townsend, 1927) é um novo registro para a Amazônia Brasileira e Ravinia effrenata (Walker, 1861) e Titanogrypa larvicida (Lopes, 1935) são novos registros para o Pará.

Abstract: The present study aims to document the community composition, abundance, and species richness of saprophytic fly species (Mesembrinellidae, Neriidae, Ropalomeridae, and Sarcophagidae) of the Volta Grande region of the Xingu River, a poorly sampled area impacted by the Belo Monte hydroelectric dam. Five collecting trips were carried out between 2014 and 2016, when traps baited with fermenting bananas were used. A total of 154 specimens, three genera, and six species were collected of Mesembrinellidae; 196 specimens, three genera, and seven species of Neriidae; 272 specimens, three genera, and six species of Ropalomeridae; and 624 specimens, 22 species and 10 genera of Sarcophagidae. Species accumulation curves for all families except Sarcophagidae demonstrated a strong tendency towards stabilization, showing that sampling efforts were sufficient to record most of the targeted species. Laneela perisi (Mariluis, 1987) (Mesembrinellidae) is a new record for the state of Pará. Among Ropalomeridae, Apophorhynchus amazonensisPrado, 1966, is a new record for Pará. Among Sarcophagidae, Helicobia aurescens (Townsend, 1927) is newly recorded from the Brazilian Amazon, and Ravinia effrenata (Walker, 1861) and Titanogrypa larvicida (Lopes, 1935) are new records for Pará.

Resumen: En | Texto: En | PDF: En

ABSTRACT Increase on intensive monocultures is an important threat to Caatinga biodiversity decrease. The use of chemical insecticides directly affects insect natural enemies of crops, but also non-target species. We aimed to test whether the diversity of sarcosaprophagous flies would be affected by agricultural management (conventional and organic). Adult dipterans were collected monthly, from July 2015 to January 2016, using a grid composed of 12 suspended traps distant 20 m from each other, baited with 150 g of sardine or bovine spleen, in each type of management. We first calculated α-diversity by Hill numbers, then evaluated the difference of diversity metrics by ANOVA. We also graphically visualise the species composition distribution by NMDS. We recorded a total of 4,651 specimens of 15 Calliphoridae and Sarcophagidae species. Chrysomya spp. were the dominant species (93.7% of all blowflies). Sarcophagidae species were sampled in low abundance, but with exclusive presence of some species in each treatment (e.g. B laesoxipha stallengi and Ravinia belforti in organic management). Although there was no difference on sarcosaprophagous fly diversity between treatments, we demonstrate empirically that mango plantations in the Caatinga harbour diverse and abundant assemblages of sarcosaprophagous dipterans, whose richness of species is comparable to other ecosystems such as rainforests and urban areas. Our results expand the known geographical range for forensically relevant species by providing a checklist of sarcosaprophagous dipterans that can thrive in agroecosystems in the Caatinga and, potentially, colonize cadavers disposed in that type of environment.

Resumen: En | Texto: En | PDF: En

Abstract A new Neotropical species of Oxysarcodexia Townsend (Diptera, Sarcophagidae) from Atlantic Forest of southeastern Brazil, Oxysarcodexia digitata sp. nov., is described and illustrated based on male and female specimens. This new species resembles O. fraterna Lopes, O. nitida Soares & Mello-Patiu, O. notata Soares & Mello-Patiu, O. vittata (Walker), and O. xon (Dodge), but can be distinguished based on differences in phallic elements. Additionally, the male of Oxysarcodexia xon (Dodge, 1968) is redescribed and illustrated, its female is described for the first time, and new records is presented.

Resumen: En | Texto: En | PDF: En

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.
