SALAZAR-ORTEGA, Jorge. Study of successional entomofauna associated to domestic pig (Sus Scrofa) corpse decomposition in field conditions. Univ. Sci. [online]. 2008, vol.13, n.1, pp.21-32. ISSN 0122-7483.

During July to September of 2003, characterization of entomofauna attracted by decomposition of two pigs (Sus scrofa) was carried out in the experimental farm of Federación Nacional de Cafeteros de Colombia at Consacá (Nariño). One of the two pigs was used as a control sample. Pioneer settler insects of carcass belonged to families Calliphoridae and Sarcophagidae (Diptera). From Calliphoridae individuals from Chrysomya albiceps (Wiedemann 1819), Chrysomya putoria (Wiedemann 1818), Chrysomya rufifacies (Macquart 1843) and Lucilia sp. were captured. C. albiceps and Lucilia sp. were the most abundant species. Families from Coleoptera order were also found: Histeridae, Staphilinidae, Silphidae, as predators, and Dermestidae as necrophagous. Other groups of insects were observed occasionaly. Nevertheless, as predators of Diptera grubs, individuals of Labidus sp. (Formicidae: subfamily Ecitoninae) were present during the entire decomposition process.
