Abstract

This study selected sheep as an animal model for domestic and wildlife ruminants to collect and identify arthropods of forensic importance. Two adult Merino sheep were humanely killed (each in cold and warm season) at Ukulinga Research and Training Farm of the University of KwaZulu-Natal, South Africa. Five decomposition stages were observed as fresh, bloated, active, advanced and dry stages. Calliphoridae, Muscidae and Sarcophagidae flies comprising of Chrysomya marginalis (Wiedemann), Ch. putoria (Wiedemann), Ch. albiceps (Wiedemann), Ch. chloropyga (Wiedemann.), Lucilia cuprina (Wiedemann), Musca domestica (Walker) and Sarcophaga calcifera (Boettcher) were recorded. Colonisation by coleopterans during the warm season started as early as the fresh stage with Dermestes maculatus (De Geer), Thanatophilus micans (Fabricius) and Onthophagus crassicollis (Boucomont), whilst the same species were collected from the bloated stage in the cold season. Chrysomya marginalis, M. domestica, D. maculatus, T. micans and O. crassicollis persisted on the carcass throughout the five stages of decomposition during the warm season. Results from this study generated important information on the endemic arthropod species that are attracted to sheep carcass during the warm and cold season in a locality of the KwaZulu-Natal province and their succession pattern can be further investigated as potential indicator species in estimating the post-mortem interval in this locality.

南非夸祖鲁-纳塔尔省绵羊尸体上具有法医学意义的甲虫和苍蝇的探索性研究

本研究选择绵羊作为家养和野生反刍动物的动物模型，以收集和鉴定具有法医学意义的节肢动物。在南非夸祖鲁-纳塔尔大学的Ukulinga研究和训练农场，两只成年美利奴羊被人道杀害（每只都在寒冷和温暖的季节）。观察到五个分解阶段，即新鲜、膨胀、活跃、晚期和干燥阶段。记录了丽蝇科、蝇科和Sarcophagidae蝇类，包括边缘金蝇（Wiedemann）、灰蝇（Wiedmann）、白蝇（Widdemann）、绿蝇（Widemann）、铜蝇（Wiendemann）、家蝇（Walker）和钙化Sarcophaga（Boettcher）。鞘翅目动物在温暖季节的殖民早在新鲜阶段就开始了，包括斑毛鳞翅目动物（De Geer）、米斑塔毛鳞翅类动物（Fabricius）和粗毛甲鱼（Boucomont），而在寒冷季节的膨胀阶段也采集到了相同的物种。在温暖季节的五个分解阶段中，边缘金黄色藻、M.domestica、D.maculatus、T.micans和O.crassicolis一直存在于尸体上。这项研究的结果产生了关于夸祖鲁-纳塔尔省一个地区在温暖和寒冷季节被绵羊尸体吸引的地方性节肢动物物种的重要信息，它们的演替模式可以作为估计该地区死后间隔的潜在指示物种进一步调查。

期刊介绍： African Entomology (ISSN 1021-3589 – print / 2224-8854 – online) replaced the old Journal of the Entomological Society of Southern Africa in 1993. A single volume consisting of two issues (March and September) is published annually. The journal is indexed in all major abstracting journals African Entomology is a peer reviewed scientific journal that publishes original research articles and short communications on all aspects of entomology, with an emphasis on the advancement of entomology on the African continent.
