摘要:AbstractObjectivesCalliphorids especially blowflies are act as important forensic indicators as they are foremost visitors of the corpse and act as silent witness after the accomplishment of crime.MethodsIn present case study immature stages of blowflies utilized for PMI estimation. Postmortem Interval (PMI) of a highly putrefied male corpse in advanced stage of decomposition was estimated. Corpse was found under the culvert of Bijapur – Bhopalpatnam road, Village Modakpal, District Bijapur, State Chhattisgarh, India. PMI was determined with the help of Accumulated Degree Hours (ADH) method based on developmental period of third instar larvae of BlowflyChrysomya megacephala(Fabricius). Tentative PMI of corpse is 5.5 days. Apart fromChrysomya megacephalaimmature stages as well as adults ofChrysomya rufifaces(Macquart) were also collected from deceased body. Entomological samples were sent for identification to the department of Zoology and Environmental Sciences, Punjabi University, Patiala, India.Results and conclusionsLarval stages were identified based on anterior and posterior spiracles and cephalophrangeal apparatus. Adults were identified based on their morphological characters. For accurate PMI estimation correct insect identification and meteorological data of crime scene are key parameters.
