从1993年到2008年，在瑞士西部进行了刑事调查，特别关注绿头苍蝇和肉蝇物种，以便应警察当局的要求估计死亡时间。在160个病例中，仅在33个病例中发现了肉蝇。本文报道了肉蝇属5种（S. africa，S. argyrostoma，S. caerulescens，S. similis和S. sp.）。在尸体（幼虫期）上发现的主要种类是S。银口鱼该物种在瑞士的热常数（K）为380.6 +/- 16.3（平均值+/- S.D.）。degree-days.除了S。除了在尸体上发现过三次幼虫阶段的青虫外，其他三个物种在法医学上的重要性较小。S.银汉鱼在夏季及室内出没。该物种在尸体上定居，通常与绿头苍蝇物种在同一天，它可以用来估计死后的时间间隔。其他物种根据其生物学和生态学的现有知识进行了讨论。建议将凭单材料存放在博物馆，以便有关专家进一步研究，从而帮助调查人员并避免误认。(c)2012爱思唯尔爱尔兰有限公司保留所有权利。
From 1993 to 2008, criminal investigations were conducted in the western part of Switzerland with special attention to blowfly and flesh fly species in order to estimate the post-mortem interval when requested by the police authorities. Flesh flies were found in only 33 cases out of 160. Five species of the genus Sarcophaga were identified (S. africa, S. argyrostoma, S. caerulescens, S. similis and S. sp.). The main species found on corpses (larval stage) was S. argyrostoma. The thermal constant (K) calculated for this species in Switzerland is 380.6 +/- 16.3 (mean +/- S.D.) degree-days. With the exception of S. caerulescens, found three times in the larval stage on corpses, the three other species are of minor forensic importance. S. argyrostoma is found during summer and indoors. This species colonises dead bodies, usually the same day as blowfly species, and it could be used to estimate the post-mortem interval. Other species are discussed in the light of current knowledge on their biology and ecology. It is recommended that voucher material be deposited in a museum, allowing further studies by relevant specialists, thereby helping investigators and avoiding misidentifications.
