Each of six rabbits and six guinea pigs is divided into 2 groups, where the first was killed by tramadol and the second group was killed by asphyxia as a control experiment. Generally, decomposition process was observed to have a slower rate in winter. Reaching to the skeletal stage was delayed in tramadolintoxicated carcasses in comparing to the control carcasses. A total of 12966 arthropod individuals (Immature stages and adults) were collected. In concern of class Insecta, 67 species belonging to 6 Insecta orders and 2 Arachnida orders, 37 families and 51 genera were identified from this study during winter and summer seasons. Significantly lower numbers of immatures were observed and collected in the present study from the treated carcasses. The proportions of adult insects were also significantly different in control carcasses when compared with tramadol intoxicated ones in both winter and summer season for both rabbits and guinea pigs. This study provides background for the influence of tramadol on the colonizing wave of arthropod fauna which is of relevance to forensic science. We can conclude that drugs and toxins present in a decomposing body may alter the rate of insect invasion of that body.

The identification was confirmed using integrative approach of morphology and molecular technique.

These members were collected from, on, in, around and beneath the carcasses of rabbits and guinea pigs. Results: The families which collected from the carcasses are as follows: Agromyzidae (one subfamily, one genus and only one species), Calliphoridae (three subfamilies, three genera and sex species), Dolichopodidae (one subfamily, one genus and only one species), Drosophilidae (one subfamily, one genus and only one species), Ephydridae (one subfamily, one genus and only one species), Fanniidae (one genus and only one species), Muscidae (two subfamilies, three genus and four species), Phoridae (one subfamily, one genus and only one species), Piophilidae (one subfamily, one genus and only one species), Psychodidae (one subfamily, one genus and only one species), Sarcophagidae (two subfamilies, two genera and three species), Sphaeroceridae (one subfamily, one genus and only one species), and finally Ulidiidae (one subfamily, one genus and only one species). Only seven of which (Calliphoridae, Fanniidae, Muscidae, Phoridae, Piophilidae, Sarcophagidae and Ulidiidae) are of forensic importance or necrophagous. Other families are the following: Drosophilidae, Psychodidae, Agromyzidae, Dolichopodidae, Ephydridae, and Sphaeroceridae are of minor importance as forensic indicators. Conclusions: Taxonomic keys for the adults which collected from the carcasses were constructed. Also diagnosis, synonyms, photographs and the forensic importance for the taxa were provided.

Generally, control rabbits and control guinea pigs were faster in their decay comparing the corresponding figure of the zinc phosphide-intoxicated group. A delay in colonization of insects was noticed either in the winter season for both groups, or additionally for the zinc phosphide groups. The associated insect fauna was represented in 6 orders, 20 families, and 36 genera and species. Necrophagous arthropods that supported decomposition of carcasses were mainly of orders Diptera and Coleoptera. Calliphoridae was the first insect family that colonized the different carcasses. The mean numbers of control immature dipterous maggots and similarly, the control coleopteran larvae significantly exceeded the corresponding mean numbers for the zinc phosphide-intoxicated groups in both winter and summer seasons in either rabbits or guinea pig groups. Moreover, the mean numbers of dipterous maggots or coleopteran larvae of rabbits significantly surpassed the corresponding figures for guinea pigs in both seasons. This study may add as a reference for the succession wave arthropod fauna in Cairo Governorate in winter and summer seasons. Moreover, it is the first record of the arthropod successive wave on zinc phosphide-intoxicated remains.

Twenty nine species under twenty one genera and nine families were collected from decaying carcasses (Rabbits & Guinea pigs). Keys, diagnosis, synonyms, photographs and the forensic importance were given to clarify the status of each species. [Rabab F. Sawaby, Hayam EL Hamouly and Reham H. Abo-El Ela.
