Abstract. The calliphorids flies comprise a heterogenous family found in all zoogeographical regions, with over 1,000 species and 150 genera described. The blow flies have a great medical and veterinary importance, and can be use in forensic science, especially in order to estimate the postmortem interval. Despite its wide distribution and importance, the group presents many taxonomic problems, and many conflicting records regarding the number of species in the Neotropical Region. In this paper, we list all species of Calliphoridae found in the Americas south of Mexico, based on reports in the literature between the years 1960 and 2012. There are 29 genera and 99 species recognized distributed in seven subfamilies: Calliphorinae (three genera and eight species), Chrysomyinae (seven genera and 28 species), Luciliinae (one genus and 17 species), Mesembrinellinae (nine genera and 33 species), Polleniinae (one genus and one species), Rhiniinae (one genus and one species), and Toxotarsinae (seven genera and 11 species). An identification key for the species that occur in Brazil is presented.Keywords: Biodiversity; Bluebottles; Checklist; Neotropical Region; Taxonomy. Lista Atualizada de Nomes Válidos de Moscas-Varejeiras (Diptera: Calliphoridae) das Américas ao Sul do México, com uma Chave para as Espécies que Ocorrem no BrasilResumo. Os califorídeos constituem uma família heterogênea encontrada em todas as regiões zoogeográficas, com mais de 1.000 espécies e 150 gêneros. As moscas-varejeiras possuem grande importância médica e veterinária, e podem ainda ser utilizadas nas ciências forenses, principalmente para estimar o intervalo pós-morte. Apesar da sua vasta distribuição e importância, o grupo apresenta muitos problemas taxonômicos e diversos registros conflitantes no tocante ao número de espécies presentes na região Neotropical. Neste artigo nós listamos todas as espécies de Calliphoridae encontradas nas Américas ao sul do México, baseadas em registros na literatura entre os anos de 1960 e 2012. Existem 29 gêneros e 99 espécies reconhecidas e distribuídas em sete subfamílias: Calliphorinae (três gêneros e oito espécies), Chrysomyinae (sete gêneros e 28 espécies), Luciliinae (um gênero e 17 espécies), Mesembrinellinae (nove gêneros e 33 espécies), Polleniinae (um gênero e uma espécie), Rhiniinae (um gênero e uma espécie) e Toxotarsinae (sete gêneros e 11 espécies). Uma chave de identificação para as espécies que ocorrem no Brasil é apresentada.

In order to study the morphology of young Chrysomya albiceps forms, newly hatched larvae were collected at 2 hr intervals, during the first 56 hr; after this time the collection was made at 12 hr intervals. For identification and drawing, larvae were placed between a slide and a coverslip. The cephalopharyngeal skeletons along with the first and last segments were cut off for observation of their structures and spiracles. The larvae present microspines, which are distributed randomly throughout the 12 segments of the body surface; the cephalopharyngeal skeleton varies in shape and extent of sclerotization according to larval instar; the second and third instars have relatively long processes (tubercles) on the dorsal, lateral and ventral surfaces, with microspine circles on the terminal portio

The ecology of anopheline species (Diptera, Culicidae) was studied in the vicinity of the Serra da Mesa Reservoir, State of Goiás, Brazil. Climatic factors and frequency of anopheline populations were analyzed. Bimonthly human-bait and Shannon trap captures were conducted for 36 consecutive months (January 1997 through December 1999). A total of 5,205 adult anophelines belonging to five species were collected. Anopheles darlingi was the most frequently collected anopheline (61.4%), followed by An. albitarsis s.l. (35.4%), An. triannulatus. (2.5%), An. oswaldoi (0.4%), and An. evansae (0.2%). The water level and vegetation along the banks of the reservoir were crucial to the frequency of the various anopheline species. Climatic factors had a secondary influence. The reservoir's water-level stability, increased frequency of An. darlingi, and the arrival of gold prospectors were responsible for the increase in malaria cases.

We dissected the digestive tract of 245 females in pools of 35 flies forming 7 groups. These flies were Lutzomyia longipalpis originating from Lapinha Cave, Lagoa Santa, Minas Gerais. Out of the 8 species of bacteria isolated there was a predominancy of Gram negative bacterias (GNB) in the group of non-fermenters of sugar belonging to the following species: Acinetobacter lwoffii, Stenotrophomonas maltophilia, Pseudomonas putida and Flavimonas orizihabitans. The group of GNB fermenters were: Enterobacter cloacae and Klebsiella ozaenae. In the Gram positive group we isolated the genera Bacillus thuringiensis and Staphylococcus spp.
