We describe here a case of multiple colonization of a male cadaver found indoors in the municipality of Jaboatao dos Guararapes, Brazil. The body was colonized by six species of Diptera: Chrysomya albiceps, Chrysomya megacephala, Chrysomya putoria (Calliphoridae), Megaselia scalaris (Phoridae), Fannia trimaculata (Fanniidae), and Peckia (Peckia) chrysostoma (Sarcophagidae). The most abundant species were C. albiceps (65.0 % of all emerged adults) and C. megacephala (18.6 %). The case illustrates the ability of six insect species to simultaneously colonize a corpse in an indoor environment and represents the first collaboration between the forensic police and entomologists in Northeastern Brazil. We provide here the first record of two species, F. trimaculata and Peckia (P.) chrysostoma colonizing a human cadaver. We also report the first case of cadaver colonization by C. putoria and M. scalaris in Northeastern Brazil. Information on the development time of two species, C. albiceps and C. megacephala, were used to discuss the estimation of the post-mortem interval. Considering that the region harbors the highest rates of homicide in Brazil, implications of these findings for the consolidation of forensic entomology in the region are discussed.
我们在此描述了一起在巴西若阿比绍市室内发现的男性尸体被六种双翅目昆虫同时寄生的案例。这些寄生昆虫分别是：黄尾黑麻蝇（Chrysomya albiceps）、红头丽蝇（Chrysomya megacephala）、巨尾阿丽蝇（Chrysomya putoria）（丽蝇科）、小眼蕈蚊（Megaselia scalaris）（菌蚊科）、三斑家蝇（Fannia trimaculata）（家蝇科）和金带麻蝇（Peckia）（Peckia）chrysostoma（麻蝇科）。其中数量最多的两种是黄尾黑麻蝇（65.0%的所有成虫）和红头丽蝇（18.6%）。该案例说明了六种昆虫同时在室内环境中寄生一具尸体的能力，并且代表了巴西东北部法医警察和昆虫学家之间的首次合作。我们在此提供了两种新的记录，即三斑家蝇和金带麻蝇寄生人体尸体。我们还报告了在巴西东北部首次发现巨尾阿丽蝇和小眼蕈蚊寄生尸体的案例。两种昆虫，即黄尾黑麻蝇和红头丽蝇的发育时间信息被用来讨论死后间隔时间的估计。鉴于该地区是巴西凶杀率最高的地区，因此讨论了这些发现对该地区法医昆虫学的巩固的影响。
