Resumen
The objective to this work was to make the growing anddevelopmental curves of the first species of dipteracollected from a infested carcass of domestic pig (Susscrofa), exposed to decomposition in the San José deGuaúsa farm, from Bogotá. These curves allow us toestimate precisely the postmortem interval. Domesticpig was the biomodel used because its alimentary habits,villous density and decomposing processes, similar tohuman. Insect colonization began the same day ofsacrifice of the pig. Egg masses found in the carcass infresh stage were collected from day first to fifth andthen sowed and reared in laboratory conditions untiladulthood. The emerged species were Sarconesiamagellanica (Le Guillou) (Diptera: Calliphoridae) andCompsomyiops verena (Walker) (Diptera: Calliphoridae).The mean time elapsed from egg to adult in dominantspecie, Sarconesia magellanica, was 40 days. Onmorphometric, instar time, and environmental data wasapplied a generalization of multivariate analysis ofvariance, from which growing and developmental curveswere made. These results are of singular importance todetermine the postmortem interval and may beextrapolated to human carcasses exposed to similarenvironmental conditions, to help resolve legal caseswhere time between finding the infested carcass andthe real time of death is unknown
