| Research Abstract |
Both the decomposition process and sarcophagous insect fauna were similar to warm/cold migratory season, making estimation of the postmortem interval of a decayed corpse found in spring based on postmortem phenomena difficult at present. It appeared that understanding the annual period of the initial colonization would be important for estimating postmortem interval for a decomposed corpus being fed by large dipteran larvae and found in spring within this outlying residential area. It was thought the gas odor was the factor attracting mature female flies. However, no differences were observed in either the insect species colonizing the piglet carcass or the degree of decomposition of the carcass, suggesting that insect fauna and the decomposition process would be affected by seasonal factors such as temperature. The experimental results of pork slice placed outdoor suggest a period of reduced activity of the early colonizer blowflies in midsummer.
