Aspects related to epidemiology of flies belonging to Fannia genus were studied in order to determine predisposing factors for its occurrence in layer hens houses of commercial farms in the state of Minas Gerais, Brazil. An observational, analytical and sectional survey was conducted to verify major epidemiological aspects associated to infestations. This research was accomplished starting from an adapted secondary database of and structured with information on the presence and absence of ectoparasites and arthropods, characteristics of chicken houses, the poultry, type of facilities, geographical location and the management. The study was conducted in four hundred and thirty one houses located in forty three farms visited in 2012 year in the state of Minas Gerais. Ten farms (23.25%) and sixty eight houses (15,77%) were observed the presence diptera belonging to Fannia genus. The specie Fannia admirabilis was found in four farms (9,30%), Fannia albitarsis in two farms (4,65%) and only in one farm (2.32%) was observed the presence of Fannia canicularis. For three farms 6,98% was no possible to identify the species only Fannia genus. The epidemiological aspects for the occurrence of these flies were investigated using Poisson regression models. Characteristics such as farm, city of farm, presence of Histeridae beetles, type of facility (cage, on the floor with or without bedding) and the existence of mechanical removal of manure were associated with the occurrence of Fannia spp.

The family Fanniidae is newly recorded to New Caledonia. Adult male and female of Fannia capitalis Pont are illustrated as well as the peculiar male terminalia, the female ovipositor, and the egg. Male phallic process and egg are described for the first time.

Fanniidae (Insecta: Diptera) is a relatively small family (ca. 350 spp.) with fve genera, of which Fannia Robineau-Desvoidy, 1830 and Euryomma Stein, 1899 have Neotropical distributions. Some of these species are almost always found in forensic studies. Forensically relevant species have been neglected, despite recent forensic studies that suggest their importance for estimating post-mortem interval (PMI). Thus, current and updated keys to identify adults or larvae on carcasses are unavailable for the most important species. While immature stages are important in estimating PMI, evidence suggests that adults (Fanniidae as well as other families) may also be useful for this purpose. Here we provide a key to males of the species of Fanniidae (found on corpses and other decomposing organic matter) with a checklist of species that have been used in forensics in the Neotropical region. The key comprises all 38 species of Fannia and Euryomma that have already been successfully used in forensics, and species that are potentially useful for estimating PMI. These records were found after reviews of the literature and data from entomological collections. Photographs and illustrations of the main characters in the key are provided Fil: Grisales, Diana.

Inventories on necrophagous insects carried out in Brazil encompass mostly species from the southeastern and central-western regions of the country. This review aims to produce the first checklist of necrophagous Diptera and Coleoptera species of forensic relevance in northeastern Brazil, an area that concentrates high rates of homicides. We performed a literature survey on scientific articles, theses and dissertations regarding necrophagous insect species in the region, and contacted scientists who develop research on forensic entomology. Fifty-two species of Diptera belonging to eight families with previous record of necrophagy were reported in the region: Sarcophagidae, Calliphoridae, Muscidae, Fanniidae, Piophilidae, Phoridae, Anthomyiidae and Stratiomyidae. Coleopteran species from six families of forensic relevance were registered, although taxonomical identification remained superficial. Bait traps were the most frequent methodology used, followed by collection on animal carcasses. Seven Dipteran species from two families were registered on human cadavers. All species had been previously reported in other Brazilian states and/or other countries, although none has been effectively used in legal procedures in the region. The status of research on forensic entomology in northeastern Brazil is incipient, and the checklist produced here contributes to the knowledge on the local diversity of necrophagous insects.

Brazilian studies involving entomological succession patterns in carcasses have been used to describe the necrophagous entomofauna of a determined municipality or region with forensic objectives. Following the same objectives, an ecological study with 10 calyptrate dipterans was carried out during the winter of 2007 and the summer of 2008 in the metropolitan region of the municipality of Rio de Janeiro. The aim of this study was to describe several aspects of the phenology of these species in three neighbouring areas. Carcasses of three domestic pigs (Sus scrofa L.) were used in each season as models for forensic and legal medicine investigations in the region. Temperature, relative humidity and rainfall were measured daily and their relations with population abundance of the colonising species and the decomposition stages were analysed. Ten fly species were recorded to be colonising the carcasses, five of which belonged to the Calliphoridae family, three to the Muscidae, one to the Fanniidae and one to the Sarcophagidae family. Data show preferences of these species for climatic season and decomposition stage, as well as for the studied area and suggest that short distances can significantly influence the abundance of some species.

The calyptrate dipterans are the most important decomposers of human cadavers. Knowledge of their species and distribution are of great importance to forensic entomology, especially because of the enormous diversity in Brazil. Carcasses of domestic pigs (Sus scrofa, L) were the experimental models used to attract calyptrates of forensic interest during the winters of 2006 and 2007 and the summers of 2006 and 2008. A total of 24,423 specimens from 44 species were collected (19 Muscidae, 2 Fanniidae and 23 Sarcophagidae), three of which were new records of occurrence and 20 of which were new forensic records for the state of Rio de Janeiro. Fourteen of these species were newly identified as forensically important in Brazil.

Taxonomy of Fanniidae (Diptera) of southern Brazil - I: a new species and a key to identification of Euryomma Stein. Euryomma Stein and Fannia Robineau-Desvoidy are the only genera of Fanniidae (Diptera) occurring in South America. The present study concerns only to Euryomma species. Identification keys to Fanniidae genera and to the species of Euryomma of southern Brazil are provided. Redescriptions of the previously recorded species and the description of Euryomma palpingens sp. nov. from Ponta Grossa, Parana, are presented. Euryomma carioca Albuquerque is newly recorded from Santa Catarina and Rio Grande do Sul, and E. peregrinum (Meigen) from Santa Catarina. Drawings of the main diagnostic characters and male and female terminalia of all species are included.

Fannia Robineau-Desvoidy is known from 63 neotropical species, 24 of them with occurence in Rio de Janeiro State. Two new species from Rio de Janeiro State are added to the genus: F. tibialis, sp. n and F. unica, sp. n. Male specimens of both are described. Morphological characters and terminalia are illustrated. Each species is briefly discussed. Fannia Robineau-Desvoidy é conhecida por apresentar 63 espécies neotropicais, 24 delas com ocorrência no Estado do Rio de Janeiro, sendo que duas novas espécies procedentes desse Estado foram acrescidas aos gêneros: F. tibialis, sp. n. e F. unica, sp. n. São descritos os exemplares machos de ambas as espécies, cujos caracteres morfológicos e terminália são ilustrados. Também é apresentada breve discussão sobre cada uma das novas espécies.

Synanthropic flies outstanding beside other flies due their relative abundance close to domestic animals and human population, to which they are able to cause myiasis or transmit pathogenic agents. As they're necrophagous they act as corpse decomposers and are useful in the forensic entomology in the post mortem interval determination. This study aimed to know flies diversity and abundance in Campo Grande, State of Mato Grosso do Sul. Captures were made weekly, utilizing three traps baited with decaying fish meat, from June of 2008 to May of 2009 in a remainder ciliary forest of the Embrapa's Cattle Beef Experimental Farm. The dipterans families that were considered and respectively number of collected specimens were: Calliphoridae (105,334); Muscidae (27,999); Sarcophagidae (21,083); Fanniidae (17,759) and Mesembrinellidae (305), totalizing 172,480 dipterous. To the local known species some Muscidae were increased as follows: Neomuscina atincticosta, Pseudoptilolepis elbida, Polietina orbitalis, Polietina flavithorax, Scutellomusca scutellaris, Graphomya analis and Morellia couriae. As moscas sinantrópicas se destacam pelo fato de serem relativamente abundantes junto à população humana e animais domésticos, podendo causar a estes miíases ou transmitir agentes patogênicos. Por serem necrófagas, atuam na decomposição de cadáveres e são úteis para a entomologia forense como indicadores na determinação do intervalo post mortem - IPM. Este trabalho visou conhecer a diversidade e a abundância das espécies em Campo Grande, Estado de Mato Grosso do Sul. As capturas foram realizadas semanalmente, com três armadilhas, utilizando isca de peixe deteriorado, durante o período de junho de 2008 a maio de 2009 em mata ciliar remanescente na fazenda experimental da Embrapa Gado de Corte. Foram consideradas as seguintes famílias de dípteros, seguidas pelo número de exemplares obtidos: Calliphoridae (105.334); Muscidae (27.999); Sarcophagidae (21.083); Fanniidae (17.759) e Mesembrinellidae (305), totalizando 172.480 dípteros. Foram acrescentadas às espécies de Muscidae já notificadas para o local deste estudo: Neomuscina atincticosta, Pseudoptilolepis elbida, Polietina orbitalis, Polietina flavithorax, Scutellomusca scutellaris, Graphomya analis e Morellia couriae.

This study reports the first occurrence of Muscidifurax raptorellus (Hymenoptera: Pteromalidae) in Brazil. Chicken manure samples, collected at two-week interval, were taken to the laboratory and the pupae were extracted by the method of flotation. Each pupa was placed in capsules of colorless gelatin until the emergence of dipterous or their parasitoids. In the study, ten pupae of Fannia pusio (Wiedemann, 1830) (Diptera: Fanniidae) were obtained, two of which yielded the parasitoid M. raptorellus . The percentage of parasitism was 5.0%.

Foram calculadas a extensão e sobreposição de nichos tróficos de dípteros caliptrados, criados em variados ambientes do Rio de Janeiro (área rural, urbana e florestal), utilizando-se diferentes substratos de criação (banana amassada, carcaça de camundongo, peixe (sardinha), fígado bovino, camarão e fezes humanas frescas. Foram criadas 14.294 moscas, pertencentes às famílias Calliphoridae, Fanniidae, Muscidae e Sarcophagidae. As maiores sobreposições de nichos tróficos, entre as espécies, foram assim constatadas: área rural: Phaenicia cuprina versus Chrysomya megacephala; área urbana: Phaenicia eximia versus Sarcodexia innota e P. eximia versus Synthesiomyia nudiseta; área florestal: P. eximia versus Hemilucilia flavifacies. Na área rural, o nicho mais extenso foi o de Peckia chrysostoma; na área urbana, o de S. nudiseta e Musca domestica. Euboettcheria collusor e P. eximia, na floresta, foram as espécies com nichos tróficos mais amplos.

A study comparing the morphology of the proboscis of the following muscoid species is presented: Scatophaga stercoraria (Linnaeus, 1758) (Scatophagidae), Fannia canicularis (Linnaeus, 1761) (Fanniidae), Taenomyia auricollis Stein, 1918 (Anthomyiidae) and Phaonia valida (Harris, 1780) (Muscidae). Comparisons were made with Archiborborus sp. (Acalyptratae, Sphaeroceridae), Calliphora vicina Robineau-Desvoidy, 1830 (Oestroidea, Calliphoridae) and other muscids.
