Abstract

OLEA, Sofía M. et al. Calliphoridae (Diptera) in pedemontane forest patches with different degrees of human intervention in Tucumán (Argentina). Rev. Soc. Entomol. Argent. [online]. 2012, vol.71, n.3-4, pp.249-256. ISSN 0373-5680.

The Yungas ecoregion is located in the northwest of Argentina, where the ecological information on Calliphoridae is scarce. The aim of this work was to provide the information on richness, composition and abundance of Calliphoridae along urban-rural gradients in the Yungas. Monthly samples were obtained between November 2009 and May 2010 from three localities: San Miguel de Tucumán (urban site), Nueva Esperanza (rural site) and El Taficillo (forest). Eight blowfly species were collected: Lucilia cluvia (Walker), Lucilia sericata (Meigen), Lucilia sp., Chrysomya megacephala (Fabricius), Chrysomya albiceps (Wiedemann), Chrysomya putoria (Wiedemann), Paralucilia pseudolyrcea (Mello) and Calliphora nigribasis Macquart. The Synanthropy Index (SI) was calculated for dominant species. In addition, the association between the abundance of species and the sites was analyzed using Principal Component Analysis. Lucilia cluvia was dominant in all sites and samples, with a slight predominance in sites less affected by urbanization. These results described the assemblage of Calliphoridae present in the lower montane forest in Tucuman, with a high dominance of Lucilia species.
