大多数法医昆虫学演替研究都是利用猪或兔的身体进行的；然而，关于昆虫在人身体和动物身体上的演替模式的差异的研究很少。为了弄清人类身体和动物身体在腐烂和昆虫演替模式上的差异，2013年8月，在深圳中国，将一具49.5公斤的人身体、两具大型猪身体(45公斤和48公斤)、两具小型猪身体(23公斤和25公斤)和两只兔子身体(均为1.75公斤)放置在相同的野外条件下进行比较研究。结果表明：(1)从新鲜到骨骼的时间顺序为：人尸>大猪尸>小猪尸>兔尸；(2)在较大的身体上昆虫群落(包括发育阶段)较为复杂，顺序为人尸=大猪尸>；小猪尸&兔尸：(3)同一取证重要蝇种在所有身体上的发育速度一致；(4)所有已鉴定的丽蝇科物种都能在人身体和大小猪身体上完成一代发育，而在兔尸上只有一小部分丽蝇科物种能完成一代发育；(5)甲虫能在人身体和大小猪身体上繁殖后代，但不能在兔身体上繁殖后代。本研究为人类身体和动物身体的腐烂和昆虫演替模式提供了有用的比较数据。(C)2016爱思唯尔爱尔兰有限公司。保留所有权利。
Most forensic entomological succession studies have been carried out using pig or rabbit carcasses; however, there have been few studies on the differences between insect succession patterns on human cadavers and on animal carcasses. In order to clarify the differences between decomposition and insect succession patterns of human cadavers and animal carcasses, one 49.5 kg human cadaver, two large pig carcasses (45 and 48 kg), two small pig carcasses (23 and 25 kg) and two rabbit carcasses (both 1.75 kg) were placed in the same field conditions in Shenzhen, China for a comparative study on August, 2013. The results indicated that: (1) The duration from fresh to skeletonization is in order of human cadaver > large pig carcasses > small pig carcasses > rabbit carcasses; (2) insect assemblages (including developmental stages) are more complex on larger carcasses, in order of human cadaver = large pig carcasses > small pig carcasses > rabbit carcasses; (3) the developmental rates of the same forensically important fly species on all carcasses are consistent; (4) all identified species of Calliphoridae can complete development of one generation on human cadaver, and both large and small pig carcasses, while on rabbit carcasses, only a subset of the Calliphoridae species can finish development of one generation; (5) beetles can generate offspring on human cadaver, and both large and small pig carcasses, while they do not generate offspring on rabbit carcasses. This study provides useful comparative data for decomposition and insect succession pattern of human cadaver with animal carcasses. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
