This study was carried out in the Base Operacional Geólogo Pedro de Moura (BOGPM) in the Urucu River Basin, Coari, state of Amazonas, Brazil, during April, June, and October 2007, in 16 areas, 4 in primary forests (environment MT) and 12 in gaps (environments C1, C2, and C3) at different stages of vegetation recovery, with different plant cover height. We collected 3,547 specimens of lesh lies. The 3,525 individuals identi ied to species level included 10 genera, 6 subgenera, and 23 species. Sarcodexia lambens (Wiedemann) (47.1%) and Peckia (Peckia) chrysostoma (Wiedemann) (19.1%) were the most abundant species. The abundance patterns and estimated richness differed between the environments, and were separated in two groups, one of the gaps (C1, C2, and C3) and another of forests (MT). Both abundance and estimated richness were higher in the gaps (C1, C2, and C3) than in the forest (MT).

Sinantropía de Sarcophagidae (Diptera) en La Pintada, Antioquia-Colombia. Recently, populations of flies have increased in numbers given the elevated levels of organic matter waste produced by anthropic activities and domestication of animals. Such increase represents a worldwide health concern, since flies can be vectors of human diseases. The great variety of feeding and developmental habits of flies of the family Sarcophagidae taking place on animal corpses, feces and decomposed organic matter make them potential vectors of pathogens. Herein, we evaluated the synanthropic index (SI), as well as other ecological aspects of this family, through simultaneous monthly samplings in three areas with different degrees of human disturbance (urban, rural and forest). Each area had four van Someren Rydon traps, each one with a different bait (i.e., human feces, chicken viscera, fish and decomposing onion). Traps were active during 48 hours each month, and specimen collection was made every 12 hours. A total of 7 446 Sarcophagidae individuals were collected (1 275 males and 6 171 females), belonging to 27 species and nine genera. Tricharaea (Sarcophagula) canuta (SI=+96.67), Oxysarcodexia taitensis (SI=+93.85), Peckia (Peckia) chrysostoma (SI=+90.00) and Tricharaea (Sarcophagula) occidua (SI=+88.76) exhibited the highest values of synanthropy index, revealing a strong preference for human settlements. The most abundant species were Oxysarcodexia conclausa (21.80%), Ravinia effrenata (18.67%), Oxysarcodexia bakeri (11.45%) and Oxysarcodexia taitensis (10.20%), all of which exhibited preference for urban environments. Additionally, we are reporting seven new records of Sarcophagid flies for Colombia: Oxysarcodexia angrensis, Oxysarcodexia bakeri, Oxysarcodexia diana, Oxysarcodexia similata, Oxysarcodexia timida, Peckia (Peckia) pexata and Titanogrypa (Cucullomyia) placida.

“…Females may deposit first instar larvae directly onto the vertebrate host at predisposing sites (causing secondary myiasis), carcasses, decomposing organic matter, and dung (Panu et al 2000). Genus Oxysarcodexia is widely distributed in the Neotropical regions (Lopes 1946), and in Brazil, O. thornax (Walker) is found in both urban and rural areas of several states. This species is abundant in the state of Rio de Janeiro, occurring preferentially in the summer season, with the population peak between January and February (Oliveira et al 2002).…”

We report for the first time the expression of multiple protease activities in the first instar larva (L1) of the flesh fly Oxysarcodexia thornax (Walker). Zymographic analysis of homogenates from freshly obtained L1 revealed a complex proteolytic profile ranging from 21.5 to 136 kDa. Although some activities were detected at pH 3.5 and 5.5, the optimum pH for most of the proteolytic activities was between pH 7.5 and 9.5. Seven of 10 proteases were completely inactivated by phenyl-methyl sulfonyl-fluoride, suggesting that main proteases expressed by L1 belong to serine proteases class. Complete inactivation of all enzymatic activities was obtained using N-p-Tosyl-L-phenylalanine chloromethyl ketone (100 µM), a specific inhibitor of chymotrypsin-like serine proteases.Keywords: Oxysarcodexia thornax -Sarcophagidae -chymotrypsin-like serine proteasesThe genus Oxysarcodexia belongs to the Sarcophagidae family (flesh flies) whose major biological feature is the ovo-larvipary (Pape 1996). Females may deposit first instar larvae directly onto the vertebrate host at predisposing sites (causing secondary myiasis), carcasses, decomposing organic matter, and dung (Panu et al. 2000). Genus Oxysarcodexia is widely distributed in the Neotropical regions (Lopes 1946), and in Brazil, O. thornax (Walker) is found in both urban and rural areas of several states. This species is abundant in the state of Rio de Janeiro, occurring preferentially in the summer season, with the population peak between January and February (Oliveira et al. 2002).In biological systems, proteases may carry out (i) a regulatory function by activation or inactivation of specific proteins via selective proteolysis, and (ii) a nonspecific proteolytic function involved in general protein hydrolysis. Such proteolytic mechanisms are highly regulated and are involved in a variety of physiologic processes, such as programmed cell death, stress responses (heat shock and anoxia), skeletal muscle atrophy, cellcell recognition, signal transduction and learning, morphogenesis, and photoreceptor light adaptation (Mykles 1998). Different classes of proteases such as cysteine proteases, metalloproteases and serino proteases have been described both in adults and larvae of several species of the Diptera (Han et al. 1997, Rosenfeld & Vanderberg 1998, Cho et al. 1999, Noriega et al. 2002, Vierstraete et al. 2003, Okuda et al. 2005, Fazito do Vale et al. 2007, Pires et al. 2007, Rodrigues et al. 2007). Despite the existence of information about morphology, taxonomy and ecology of this genus, as far as we know, no data has been published on the biochemical traits of O. thornax. In the present study, the proteolytic profile of O. thornax first instar larvae was investigated using zymographic analysis. O. thornax adults were collected as previously described (Oliveira et al. 2002) and females were kept in a 50 ml plastic vial for 24 h at room temperature. Following death of the females, abundant live first instar larvae (L1) were released and immediately collected. Larvae were ...
