Abstract

The current study was carried out to investigate the forensic insects associated with two animal carcasses namely; dog (Canis lupus familiaris)and rabbit (Lepus cuniculus) during the summer season. A total of 687 adult insect specimens representing 9 families were collected from dog carcass placed outdoor, while 342 adult insect specimens representing 8 families were collected from dog carcass placed indoor. Diptera, Coleoptera and Hymenoptera comprised 57 %, 36 % and 7 % of insects collected from dog carcasses placed outdoor and 59 %, 37 % and 4 % of insects placed indoor. A total of 274 adult insect specimens representing 8 families were collected from rabbit carcass placed outdoor, while 68 adult insect specimens representing 5 families were collected from rabbit carcass placed indoor. Diptera, Coleoptera and Hymenoptera comprised 70 %, 19 %, 11 % and 46 %, 38 %, 16 % of the insect collected from rabbit placed outdoor and indoor, respectively. The insect succession on dog and rabbit carcasses throughout the decompositional stages showed that the Calliphorid fly, Chrysomya albiceps was the first fly attracted to the early stages of decomposition. In general, it has appeared that the diversity and numbers of forensic insects which colonize dog or rabbit carcasses were increased outdoor and decreased indoor. Moreover, forensic insects were higher in numbers on dog carcasses than on rabbit carcasses.
