Resumen
La longitud larval de Hemilucilia segmentar/a (Diptera: Calliphorldae) fue evaluada como un Indicador del intervalo post-mortem (IPM) en un modelo experimental. Se realizaron observaciones por triplicado en cadáveres de conejo, cepa New Zealand (3,8 kg), sometidos a eutanasia por dislocación cervical y expuestos a un ambiente selvático tropical. Las observaciones fueron efectuadas trisemanalmente en abril, julio y octubre de 2002 y enero de 2003. Se encontraron larvas durante los primeros 11-22 días a partir del día de exposición, pero la longitud larval dejó de aumentar luego del 11° día, excepto en una de las carcasas. La longitud larval de H. segmentaria podrían tener utilidad como elemento adicional que respalde otros criterios en la determinación del IPM, pero no debería ser interpretada como prueba determinante.
The length of post-feeding larvae of Hemilucilia segmentaria (Diptera: Calliphoridae) was evaluated as a possible indicator for post-mortem interval (PMI) in an experimental model. Triplicate observations were performed in New Zealand rabbits (3.8 kg) euthanized by cervical dislocation and exposed to a tropical jungle environment. Samples were collected three times at week in April, July and October 2002, and In January 2003. Larvae were found in the first 11 to 22 days after exposure. Mean larval length did not Increase after the 11th day, except in one case. The larval lenght of H. segmentaria may be useful as supporting evldence in addition to other PMI determination criteria, but it is not reliable by itself.
