The Dynamic of Population Succession Insect as an Indicator Forensic Activities

Abstract

The decomposition stage of carrion will attract various species of insects to come. Some species of insect will attract the carrion in the early stage of decomposition, but some of them in the late stage of death. The purpose of this research were to observe and analyze the distinctive features of insect succession on carrion. Two carrions were placed in indoor and outdoor. Insect collection and observation was done three times a day i.e, morning, afternoon and evening. Adult flying insects were collected by sweeping net, whereareas the immature insect manualy. The result showed that decomposition of the carrion indoor were faster than the corrion outdoor. Total time an early stage until skeletonization stage on carrion outdoors was 10 days and indoors for eight days. In outdoor there were found orders of Diptera (i.e Muscidae, Calliphoridae, Sarcophagidae, Tachinidae), Coleoptera (Chrysomelidae, Staphylinidae, Scarabeidae, Silphidae), Hymenoptera (Formicidae), Hemiptera, Blataria and Orthoptera (Grillidae). However, in indoors there were found the order of Diptera (Muscidae, Calliphoridae, Sarcophagidae, Tachinidae), Coleoptera (Chrysomelidae, Staphylinidae, Scarabeidae, Silphidae), Hymenoptera (Formicidae), Hemiptera, Lepidoptera, and Aranea. Immature insects that are found outdoors and indoors consist of three family of Diptera i.e Calliphoridae, Muscidae, and Sarcophagidae. The presence of Diptera larvae in carcasses have been found from the early stage of the death until post decay stage. The soil insects that come to the carrion outdoors consist of Protura, Collembola, Thysanura and oribatid mites. The presence of soil insects from early stage until skeletonization stage.
