Diversity of Calliphoridae (Diptera) in Brazil's Tinguá Biological Reserve

Abstract

ABSTRACTthe Calliphoridae are flies of great ecological, medical and sanitary importance because they are decomposers of organic matter, mechanical vectors of pathogenic agents, and causers of myiasis. this paper attempts to ascertain the diversity of Calliphoridae in the tinguá Biological reserve and correlate meteorological data (temperature, relative humidity of the air, and precipitation) with the occurrence of these flies. the study was conducted at a site in the tinguá Biological reserve, located in the municipality of nova iguaçu, state of rio de Janeiro, Brazil. four traps were set up using chicken viscera as bait. the experiment was conducted over the period of May 2001 to April 2002, with two monthly collections. the captured flies were killed with ether and conserved in 70% alcohol and identified in the laboratory of Diptera studies (unirio) and the laboratory of vector insect Biology and Control (fioCruz), both headquartered in the city of rio de Janeiro, rJ, Brazil. A total of 1,987 insects were captured, 37.5% belonging to the family Calliphoridae, 29.4% to Muscidae, 16.0% to sarcophagidae, and 17.1% to other families. the most representative species found was Phaenicia eximia (47.0%), followed by Hemilucilia semidiaphana (23.6%), Mesembrinella bellardiana (13.7%), Hemilucilia segmentaria (7.5%), Chloroprocta idioidea (4.9%), Chrysomya albiceps (1.2%), Chrysomya megacephala (0.9%), Phaenicia sericata (0.6%), Eumesembrinella sp. (0.5%), and Chrysomya putoria (0.1%). large numbers of Calliphoridae were noted in May, June, september and January, coinciding with low rainfall and an average temperature of 21.8 to 27.0 °C. A negative correlation was found between the number of Calliphoridae captured and meteorological factors.Keywords: population dynamics, biological reserve, Calliphoridae. ReSumo

Edge effects on the blowfly fauna (Diptera, Calliphoridae) of the Tijuca National Park, Rio de Janeiro, Brazil

“…This sex bias was also observed by Paraluppi and Castellón (1994), Marinho et al (2006) andFerraz et al (2010a), and according to Sousa et al (2010), may also be related to the position of the trap, suspended 1.5m above the ground. The collecting of February 2010 resulted in the greatest numbers of specimens ( Figure 2).…”

“…Studies on the diversity of Calliphoridae in protected areas of the state of Rio de Janeiro are restricted to the Reserva Biológica do Tinguá (hereinafter referred to as REBIO Tinguá) (Marinho et al, 2006;Mello et al, 2007;Ferraz et al, 2010b). For the PARNA Tijuca, only the publication by D'Almeida and Lopes (1983), which focused on synanthropic flies, is available.…”

Effects of forest fragmentation on dipterofauna (Calliphoridae) at the Reserva Biológica do Tinguá, Nova Iguaçu, RJ

“…While twenty-six species were collected in this study, Mello et al (2007) and Marinho et al (2006), in other locations of the same Reserve, captured 13 and 10 species, respectively. All the species collected by these two authors were also cited in this study.…”

“…Human effects in the Reserva Biológica do Tinguá have previously been reported by Marinho et al (2006), and this analysis drew attention to the need for further studies in the area. The parameters of interest include an estimation of forest conservation and human effect on dipterans in the Calliphoridae family; predominance and diversity of species on the edge and forest interior; better understanding of population dynamics; current dispersion of exotic species; identification of bioindicator species and, of paramount importance, in order to support preservation and conservation of the Atlantic Forest.…”

The classic episode of biological invasion: Cochliomyia macellaria (Fabricius, 1775) versus Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae) - evaluation of the biotic potential

“…After the introduction of the exotic C. megacephala in Brazil, C. macellaria, usually very common in urban and rural areas, has become rare in these environments (Baumgartner and Greenberg 1885, Guimarães et al 1978, Marinho et al 2003, 2006. Several studies suggested that the decline was due to the competition during the larval stages (Aguiar-Coelho and Milward-deAzevedo 1996, Faria et al 1999, Andrade et al 2002.…”
