Abstract

MARILUIS, Juan C.; SCHNACK, Juan A.; MULIERI, Pablo P.  and  PATITUCCI, Luciano D.. Calliphoridae (Diptera) from wild, suburban, and urban sites at three Southeast Patagonian localities: Calliphoridae (Diptera) de ambientes no habitados, suburbanos y urbanos en tres localidades del sudeste patagónico. Rev. Soc. Entomol. Argent. [online]. 2008, vol.67, n.1-2, pp.107-114. ISSN 0373-5680.

Species composition, relative abundance, sex ratio and habitat preference of blowflies (Diptera: Calliphoridae) from Caleta Olivia, Puerto Deseado, and Puerto San Julián (Santa Cruz Province, Argentina) were studied during late spring and summer in 2004-2005. Results showed a higher prevalence of the exotic species, Calliphora vicina (Robineau-Desvoidy) and Phaenicia sericata (Meigen) at urban sites over the natives, Compsomyops fulvicrura (Robineau-Desvoidy) and Sarconesia chlorogaster (Wiedemann), which shows a strong preference for those sampling sites either not inhabited or less influenced by human activities. Sex ratio was female biased for all species, except for Sarconesia chlorogaster, which exhibited a male prevalence over females.

Keywords : Calliphoridae; Species composition; Relative abundance; Synanthropy; Southeastern Patagonia.
