Abstract: The present study was aimed to identify the most forensically important insects species in addition to their distribution and abundance in the Al - Diwaniya province, also the succession pattern on carrion in urban and rural areas in different seasons was studied. The present study included some experiments on the effect of the quality and quantity of food on the development of some blow flies, the effect of rearing on food spiked with different concentration of Paracetamol and Amitriptyline drugs on some biologicalaspects of the blow flies, The result showed the following : ? When using fly sex - attractant poisoned bait used in the field, six dipterans flies were identified : 1 - Calliphora vicina 2 - Lucilia sericata 3 - Chrysomya albiceps 4 - Ch. Megacephala 5 - Sarcophaga africa 6 - Musca domestica the last species was the most abundant during all seasons of the year. However, when natural food bait was used, the same species of flies were recorded in addition to three species of beetles : 1 - Dermestes maculates 2 - Saprinus semistriatus 3 - Necrobia rufipes. the results also showed that the daily activity of different flies species was the varied according to ambient temperature during the day andthere was no activity recording for the flies during the night. ? The succession of insects on rabbit carrion in the urban and rural area in winter season showed that the most abundant fly species attacking the carrion during the active stage, these flies were : : 1 - C. vicina 2 - L. sericata 3 - Ch. albiceps 4 - Ch. megacephala in addition to S. africa, M. domestica and three beetles namely : 1 - D. maculates 2 - S. semistriatus 3 - N. rufipes especially during the late stage of decaying, and recoded fly : Eristalis aeneus (Diptera) accidentally appeared on the carrion. However, less number of fly species were recorded on rabbit carcass during summer season.? In general the present study showed fly species : C. vicina and L. sericata Their numbers in urban area were more than the rural area (urban species) while fly species S. africa was rural species. ? 4) skeletonization time of the rabbit carcass during summer season was three times faster than it was in winter season in both locations, urban and rural.? When C. vicina larvae reared on different animal tissues, the result showed that there were a significant differences between means of larvae weight and development time and in the emergence of adults from pupal stage, thus, the average weight of larvae was 2337 mg 2101 mg when reared on lung and liver tissues as a compared with 998.6, 1194 and 1278 mg when reared on kidney, brain and muscles after eight days of exp - Time. However the longest development period of larvae were : 10.6, 10.3 and 9.3 days and pupae 7.3, 7 and 6.6 days when reared on kidney, brain and muscles respectively, as a compared with : 7.3, 7.6 and 8 days(larvae) 5.3, 5.6 and 6 days (pupae) reared on lung, liver and heart respectively (P? 0.05).The highest emergence percentage of adult were 46.6% and 40% in the lung and liver tissues. ? Larvae of C. vicina reared on 25 and 50gm beef liver /10 larvae were 83.2 and 75.6 mg respectively compared with 67.1 reared on 100gm/10 larvae during the first four days of the experiment. However, the duration period of larvae and pupae were 10.3 and 8 days when reared on 100gm respectively, the highest emergence percentage of adults were 46% and 26.6% for larvae reared on 25 and 50gm of liver. ? Larvae of C. vicina reared on spiked liver with different concentration of Amitriptyline were significantly different to those in the control treatment, the highest means weight of larvae was 1615.3 and1474 mg when reared on liver spiked with 1.25 and o.125mg ofamitriptyline/25gmliver/5larvae respectively the lowest weight mean of larva was 1112 and 1264.6mg when reared on liver spiked with 0.025 and 0.0mg(control) respectively. The development period of larvae and pupa of C. vicina were 14.6 and 10.3 days respectively when reared on liver spiked with 1.25mg of Amitriptyline compared with 9.6 and 6.3 days in the control treatment(p>0.05).The highest percentage of adults emergence 40% was in the control treatment compared with only 13.3 when larvae reared on liver spiked with 1.25mg.amitriptyline. ? Larvae of C. vicina reared on beef liver spiked with different concentrations of Paracetamol showed different results. The highest mean weight of larva was 1735.3mg when reared on beef liver spiked with 25mg/5 larvae compared with 867.3mg in the control treatment, the development period of larvae and pupae were 12.6 and 8.6 days respectively as a compared with 9.3 and 6.3 days in the control treatment. The percentage of adults emergence was 46.6% in the control treatment compared with 13.3% in the highest concentration of drug ? The results also showed that there is a significant increase in the mean weight of larvae reared on different tissues of rabbits oral dosage with lethal dose of Amitriptyline, in the contrary weight of larvae reared on tissues of rabbits orally dosage with lethal dose of Paracetamol were decreased(p>0.05) as a compared with untreated rabbit tissues (rabbit was not dosage - control).
