| Species composition and spatial and temporal numerical trends of blow flies (Diptera, Calliphoridae) species from three southeastern Patagonia localities: Río Grande (53° 48' S, 67° 36' W) (province of Tierra del Fuego), Río Gallegos (51° 34' S, 69° 14' W) and Puerto Santa Cruz (50° 04' S, 68° 27' W) (province de Santa Cruz) were studied during November, December (1997), and January and February (1998). Results showed remarkable differences of overall fly abundance and species relative importance at every sampling site; nevertheless, they shared a poor species representation (S £ 6). The cosmopolitan Calliphora vicina Robineau-Desvoidy, the nearly worldwide Lucilia sericata (Meigen), and the native Compsomyiops fulvicrura (Robineau-Desvoidy) prevailed over... |
