Background: The entomofauna found on animal carrion, which is used as vertebrate model, can help in the estimation of postmortem interval (PMI). The aim of this study was to determine the succession pattern of insects on carrion in outdoor and indoor habitats in Fars Province, southwestern Iran. Results: A total of 19 species from nine families were collected. Chrysomya albiceps and Musca domestica were the first species to visit the outdoor carrion while only Musca domestica was seen on the indoor carrion. Sarcophaga crassipalpis, Lucillia sericata, and Histeridae species were observed exclusively on the indoor carrion while Dermestes maculatus, Piophila casei, and some hymenopteran species were the most dominant species seen on the outdoor carrion. Vespula germanica and Vespa orientalis fed on both outdoor and indoor habitats. Conclusion: Insects' succession pattern was found to differ between the two respective habitats. This is really important and could be used in medicolegal cases to estimate the PMI.

Sciences (Project No.: 916246). The journal implements double-blind peer review practiced by specially invited international editorial board members. Objective: To get new data about the ecology of mosquitoes, which would be valuable to develop programs for future provision of mosquito controls in the study area. Methods: During April to September 2012, larvae of mosquitoes were collected from six counties in south of Fars Province using dipping method. Characteristics of larval breeding places were considered based on water conditions. Species diversity was examined in terms of alpha and beta measures, with the intent of comparing mosquito diversity according to the typology of regions. Results: During this investigation, totally, 5 057 larvae of mosquitoes belonging to 5 genera and 17 different mosquito species were recognized, namely, Anopheles dthali, Anopheles fluviatilis, Anopheles stephensi, Anopheles superpictus, Culex quinquefasciatus (Cx. quinquefasciatus), Culex mimeticus, Culex perexiguus, Culex pipiens (Cx. pipiens), Culex tritaeniorhynchus, Culex theileri (Cx. theileri), Culex tritaeniorhynchus, Culex sinaiticus, Culex torrentium, Culex modestus, Ochlerotatus caspius, Culiseta longiareolata and Aedes vexans (Ae. vexans). This is the first record of Ae. vexans, Culex perexiguus and Culex modestus in the Province. Cx. pipiens (27.3%), Cx. theileri (15.9%) and Cx. quinquefasciatus (9.4%) were the most abundant species found respectively. Cx. pipiens reached the highest density in August and July, while Cx. theileri, Cx. quinquefasciatus and Ae. vexans were found in high numbers in June. Diversity analysis indicated the highest species diversity in the Mohr County (Margalef index of 1.41 and Shannon index of 1.7) and the lowest species diversity in the Lamerd County (Margalef index of 0.33 and Shannon index of 0.38). Conclusions: Regarding to this research, there are some potential vectors of medical and veterinary importance in Fars Province. Results of the present study may serve as a basis for risk assessment of emerging mosquito-borne diseases.
