Estudos sobre a fauna de Sarcophagidae (Diptera) de Belo Horizonte, Minas Gerais. III - atratividade das iscas

Abstract

Completando nosso estudo sobre a biologia da família Sarcophagidae na região de Belo Horizonte, Minas Gerais, estudamos a atratividade das diversas iscas utilizadas para capturas sistemáticas, realizadas por um ano (maio de 1980 a abril de 1981). A análise dos resultados obtidos foi feita tanto em relação à família de um modo geral, quanto às 25 espécies mais numerosas, que perfizeram um total de 9.582 exemplares dos 10.097 espécimes capturados. Para as 12 espécies em número superior a 250, fizemos uma análise estatística, a fim de verificar a possível influência das condições climáticas sobre a atratividade das iscas utilizadas.<br>Systematic collection of Sarcophagidae was made between May 1980 and April 1981 with two types of traps and five different baits. Twenty-five species were represented amingst the 9,592 specimens identified. The results are analysed to determine the attractiveness of different baits for Sarcophagidae in general and for each of the species obtained. For the commonest species, attractiveness of baits is correlated to climatic conditions

New records of Sarcophagidae (Insecta: Diptera) collected in Cerrado fragments in the municipality of Campo Grande, Mato Grosso do Sul state, Brazil

“…Its behavior has indicated necrophagous habits (Dias et al 1984b;valverDe-Castro et al 2017). This species was found in urban, rural and forest areas in Colombia, but was highly associated with the last two areas (valverDe-Castro et al 2017), agreeing with the studies carried out by Dias et al (1984a) in Belo Horizonte.…”

“…loPes (1973 collected this species with a trap containing powdered milk and agar. Oxysarcodexia carvalhoi was regarded as one of the most asynanthropic species in Belo Horizonte, Minas Gerais state (Dias et al 1984a).…”

“…Previous distribution (PaPe 1996;barros et al 2008;buenaventura & PaPe 2013;sousa et al 2015): Nearctic: Mexico (San Luis Potosí); Neotropical: Argentina, Bolivia, Brazil (Amazonas, Ceará, Distrito Federal, Maranhão, Mato Grosso, Rio de Janeiro, São Paulo), Costa Rica, Guyana, Nicaragua, Panama, Peru, Trinidad & Tobago. This species has already been collected with traps baited with fish, chicken viscera, bovine lung, human feces, and domestic pig carcass (YePez-Gaurisas et al 2013;Mello-Patiu et al 2014;sousa et al 2015); Peckia (E.) anguilla was considered asynanthropic in a study carried out in Belo Horizonte (Dias et al 1984a), but in Colombia, this species was more abundant in rural area than in urban and forest areas. In the last two areas it showed the same proportion of collected specimens and showed attraction to fish (YePez-Gaurisas et al 2013).…”

“…This species was breed more frequently in fish in a study of Calyptratae trophic niche (D'alMeiDa & D'alMeiDa 1998). Peckia (P.) chrysostoma showed strong preference for inhabited areas in Rio de Janeiro (D'alMeiDa 1983) and slight preference for the urban environment in Colombia (valverDe-Castro et al 2017), however, in Belo Horizonte, it was more frequent in uninhabited areas (Dias et al 1984a). (Dias et al 1984b;barros et al 2008;rosa et al 2011, valverDe-Castro et al 2017.…”

“…The most attractive baits were fish and bovine liver in Rio de Janeiro (D'alMeiDa 1983), and fish, in Belo Horizonte (Dias et al 1984b). This species was considered asynanthropic in studies carried out in Campinas and Rio Claro in São Paulo state (linhares 1981; souza & zuben 2016), Belo Horizonte (Dias et al 1984a), andRio de Janeiro (D'alMeiDa 1983).…”
