Abstract
Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae) es una mosca hemisinantrópica ampliamente distribuida en América Latina. Es probable que esta especie de mosca sea la más importante para la entomología forense en casuística humana y veterinaria. Hasta la fecha, no hay evidencia de la presencia de esta especie en Chile. En esta investigación se analizó la evidencia entomológica recogida de 60 cadáveres humanos encontrados por Carabineros de Chile (Labocar) desde el año 2006 hasta el 2011 desde Antofagasta (23º36' 40'' S, 70º23' 31'' W) a Punta Arenas (53º10' 00'' S, 70º56' 00'' W). Se encontraron larvas de C. albiceps en cinco casos. Para ofrecer la evidencia experimental de la presencia de C. albiceps en Chile y para generar una tabla con su ciclo de vida, se analizó la sucesión de insectos en cadáveres de cerdo en descomposición durante el verano en la zona central de Chile (35°39' 46,8"S, 71°43' 14,85'' O). El tiempo de desarrollo de la mosca de huevo a imago fue de 12 días. El 10% de las larvas más grandes de cada muestra se midió para desarrollar una tabla que podrá ser utilizada en análisis entomológico forense en Chile. Este es el primer reporte de la presencia de C. albiceps en Chile en casos forenses y se muestra la primera tabla con el ciclo de esta especie en cadáveres de cerdo que puede ser utilizado en el análisis entomológico forense humano y veterinario.

This organism is probably the most important fly species for forensic entomology in human and veterinary casuistic. Until now, there is no evidence of the presence of this species in Chile. We analysed entomological evidence collected from 60 human bodies found by Carabineros de Chile (Labocar) from 2006 through 2011 from Antofagasta (23º36' 40'' S; 70º23' 31'' W) to Punta Arenas (53º10' 00'' S; 70º56' 00'' W). Larvae of C. albiceps were found in five cases. The succession of the insect in pig carcasses decomposing during the summer in the central area of Chile (35°39' 46,83" S; 71°43' 14,85'' W) was analysed to report experimental evidence of the presence of C. albiceps in Chile and to record its life cycle. The development time of the fly from egg to imago emergence was 12 days. The largest 10% of the larvae in every sample was measured and data was presented in a table that can be used in Chilean forensic entomology. This is the first report of the presence of C. albiceps in Chile in forensic cases and we provide the first table containing the life cycle of this species in pig carcasses, this information could be used in forensic analysis for human and veterinary entomology.
