Influence of Clothing on Decomposition and Presence of Insects on Rabbit Carcasses

The decomposition rate and insects attraction to carcasses are affected by a number of factors such as temperature, body mass, the presence of poisons, humidity, and insect activity. The present study was planned to investigate the influence of clothing on both the decomposition process and the presence of insects on rabbit carcasses. The study was performed in May 2016 and involved the use of 18 live mature rabbits (Oryctolagus cuniculus L.), which were euthanized by chloroform. Rabbit carcasses were divided into three replicates with six rabbits in each replicate. Rabbits in each replicate were further subdivided, so that three rabbits were wrapped with cloth, whereas the remaining three were left unclothed. Both clothed and unclothed carcasses reached the dry stage within 6 d. The results of this study showed that clothes neither affect the decomposition process nor the presence of insects (flies and beetles). The pattern of flies and beetles, however, did vary significantly in the different decomposition stages. In total, 2,849 insects, including 2,459 flies and 390 beetles, were collected and sorted during the decomposition process. Among the dominant species, flies were assigned to the families Calliphoridae and Muscidae, whereas beetles were assigned to the families Dermestidae and Histeridae. Lucilia sericata Meigen, Musca domestica L., Dermestes maculatus DeGeer, and Saprinus moyses Marseul were the most abundant species occurring on both the clothed and unclothed carcasses. In conclusion, this study emphasized that, the clothes have no effect when dealing with decay process and insect attraction to the carrions.
