-Monthly collections were made using two traps 5 m apart exposed for 48h, containing sardines and installed at points: A -at the edge (500 m from the entrance of the Reserve); B -1200 m from the entrance and 1000 m inside the forest; and C -1700 m from the entrance and 500 m inside the forest. The purpose was to evaluate the abundance and richness of calliphorid species as a function of the environmental conditions using Pearson's correlation, compare the richness of the areas using ANOVA and Tukey's test, compare the abundances of the areas by the Kruskal-Wallis test, and also assess the possible infl uence of the anthropic presence. Rare, intermediary and common species were identifi ed. The collection totalized 8515 Calliphoridae belonging to 26 species, with a predominance of females. None of the 13 species considered common presented a correlation between abundance and temperature: only Cochliomyia hominivorax (Coquerel) and Chrysomya megacephala (Fabricius) were correlated with humidity and only Mesembrinella semihyalina Mello with precipitation. This parameter was the only climatic variable correlated with richness. The greatest abundance and richness of calliphorids occurred in September 2006. From the 13 common species, seven were considered synanthropic, indicating the effect of anthropic action in this site.

Samples were collected every month in three different sites of the Reserva Biológica do Tinguá, Brazil: site A was located on the border of the forest and sites B and C were located 1,000 and 500 m, respectively, towards the forest interior. The objective was to determine edge effects on a fragment of the Atlantic Forest. The greatest species richness was observed in sites A and B (23 species), compared with site C (16 species). Site A showed the greatest abundance and constancy, independent of the degree of synanthropy. Asynanthropic species were more abundant and constant in sites B and C. Site B showed the greatest diversity; and sites A and B showed the greatest similarity of populations. There was no significant correlation between Calliphoridae richness and canopy openness except in site C. Richness and abundance were positively correlated with subwood density, except for richness in site B.Keywords: edge effect, diversity, constancy index. Efeitos da fragmentação florestal sobre a dipterofauna (Calliphoridae) na Reserva Biológica do Tinguá, Nova Iguaçu, RJ ResumoForam realizadas coletas mensais em três pontos da Reserva Biológica do Tinguá: o ponto A estava localizado na borda da mata, e os pontos B e C estavam localizados, respectivamente, a 1000 e 500 m no interior da mata. Objetivou-se determinar os efeitos de borda em um fragmento da Mata Atlântica. A riqueza de espécies foi maior nos pontos A e B (23 espécies), em relação ao ponto C (16 espécies). No ponto A, ocorreu maior abundância e constância de califorí-deos, independente do seu grau de sinantropia. Nos pontos B e C, as espécies assinantrópicas foram mais abundantes e constantes. O ponto B apresentou a maior diversidade registrada. Os pontos A e B apresentam maior similaridade quanto às populações. Não houve significativa correlação entre riqueza de califorídeos e abertura do dossel, exceto no ponto C. Riqueza e abundância correlacionaram-se positivamente com densidade do sub-bosque, exceto para riqueza no ponto B.Palavras-chave: efeitos de borda, diversidade, índice de constância.

We report a rare case of myiasis caused simultaneously by three dipterous species. A 54 yr-old indigent patient was admitted to Andaraí Hospital with painful eruptions on the scalp. The parieto-occipital sulcus showed two lesions caused by scratching associated with deep, odoriferous and exudative pediculosis. Larvae removed with the help of forceps and vaseline produced 153 adults, identified in the laboratory as 114 specimens of Chrysomya megacephala (F., 1794), 38 of Sarcophaga (Liopygia) ruficornis (F., 1794), and one of Musca domestica (L., 1758).

This questionnaire can be used in the Brazilian hospital routine to gauge the satisfaction of patients with hospitalization.

A 63 year old black female was admitted in a public hospital complaining of itching and secretion in the gluteus for approximately one month after a trip to a rural area. The patient reported using antibiotic ointment for furuncle treatment. At the clinical examination, two hyperemic lesions showing purulent exudate were observed, and were diagnosed as furunculoid myiasis. One Dermatobia hominis larva was removed from each lesion, by means of occlusion using petroleum jelly and tweezers. Three diseases should be differentiated when dealing with this kind of occurrence: furuncles, furunculoid myiasis (caused by D. hominis) and tissue myiasis (caused by Cochliomyia hominivorax), due to the extensive tissue destruction caused by the latter.

In this contribution we examine the diversity, abundance and species richness of Calliphoridae in the Tijuca National Park, Rio de Janeiro, RJ. Specimens were collected monthly between September 2009 and August 2010, using sardines as bait, in three points: A, on the forest edge (22°56'846"S 43°17'496"W), B, 700m from it (22°57'073"S 43°17'832"W) and C, 1,200m into the forest (22°57'321"S 43°18'031"W), evaluating the indicator species at each point and the anthropogenic influences and abiotic factors that determine species distribution. A total of 16,364 Calliphoridae were collected and 17 species were identified. Species abundance was strongly positively correlated with temperature. The greatest number of flies was collected at A, but in this point, diversity was lower and most individuals collected belonged to the dominant species. Point C, conversely, had the lower abundance and the highest diversity. Chrysomya megacephala, an urban and synanthropic species, was dominant at point A, whereas Laneela nigripes and Mesembrinella peregrina, typically forest species, were considered indicators at points B and C, respectively, showing that the anthropogenic influence is more intense at the forest edge.Keywords: Atlantic Forest, diversity, environmental preservation, insect fauna.

In this study we describe the diversity of Mesembrinelinae in a biological reserve in the city of Nova Iguaçu, State of Rio de Janeiro. Traps containing sardines were distributed seasonally, at four sites: Site A (22° 58.788' S, 43° 43.459' W), in a forest edge, and sites B (22° 58.523' S, 43° 44.540' W), C (22° 58.350' S, 43° 44.678' W), and D (22° 34.865' S, 43° 27.063' W), located 1,000m, 500m, and 2,000m respectively, inwards from the edge. A total of 2,150 individuals of Mesembrinellinae were collected, representing ten species. Laneela nigripes Guimarães, 1977 was the most abundant species, followed by Mesembrinella bellardiana Aldrich, 1922, Eumesembrinella cyaneicincta (Surcouf, 1919 and Mesembrinella semihyalina Mello, 1967. These species were common and constant during the study period. Mesembrinella batesi Aldrich, 1922, Eumesembrinella quadrilineata (Fabricius, 1805 and Huascaromusca aeneiventris (Wiedmann, 1830) were the less abundant flies, being considered rare and accidental. Eumesembrinella besnoiti (Seguy, 1925) was rare and accessory. Eumesembrinella cyaneicincta, M. bellardiana, M. semihyalina and M. bicolor were mostly collected in site B, while L. nigripes was mostly collected in site C. The edge effect was not evident since the four sites showed similar populations. Site B showed a strong positive relationship between abundance and richness, in site C the correlation was positive and weak, and there was no correlation in A and D. The highest abundance of specimens was recorded during autumn and winter. These flies occurred from the edge up to 2,000m inside the forest.Keywords: blowflies, asynanthropic species, biodiversity, conservation, Atlantic Rain Forest. Mesembrinellinae
