Abstract:

this is the first report of an ongoing study on arthropofauna of forensic importance in callao, peru using a baby pig (sus scrofa linneaus, 1758) on land as a model to determine the arthropofauna over 84 days of weekly survey between 17 july and 02 october 2 000. a total of 4,405 specimens were collected belonging to five orders and eight families: cochliomyia macellaria (fabricius, 1775) (diptera, calliphoridae) (81.62%); dermestes maculatus (de geer, 1774) (coleoptera, dermestidae) (16.35%); fannia canicularis (linnaeus, 1761) (diptera, muscidae) (0.04%); saprinus aeneus (fabricius, 1775) (coleoptera, histeridae) (1.48%); necrobia rufipes (de geer, 1775) (coleoptera, cleridae) (0.45%); linepithema humile (mayr, 1868) (hymenoptera, formicidae) (0.02%); porcellio laevis latreille, 1804 (isopoda, porcellionidae) (0.02%) and hadruroides lunatus (l. koch, 1867) (scorpionida, iuridae) (0.02%). larvae accounted for 76%, pupae 14% and adults 10% of the total collected. the arthropods were into three: necrophages (98.01%), predators (1.95%) and omnivorous (0.04%). c. macellaria were significantly higher during the decayed stage; by contrast d. maculatus was much higher in dry remains stage. the highest diversity with the shannon-weaver (h') and pielou (j) index were found during the advanced decayed stage. the absence of species of genus chrysomyia robineau-desvoidy, 1830 is discussed.
