To date, entomology has not been used in legal investigations in Kuwait. Indeed, this is true of most Arab countries in the Middle East. There are no known studies on necrophagous species in the region, nor any knowledge of cadaver succession with which to compare case material. Here we report the first case of application of forensic entomology in Kuwait. In Al-Rowdah district, a man was found dead in his bedroom which was air-conditioned and the windows were closed. The temperature of the room was 20°C. The cause of death was morphine overdose. At autopsy, fly larvae were collected from the blanket with which the body was wrapped and were identified as postfeeding 3rd instars of Parasarcophaga (Liopygia) ruficornis using molecular analysis. In addition, the face and neck were extensively and exclusively colonized by different stages of Chrysomya albiceps (secondary fly). Based on the age of P. ruficornis full mature 3rd instars and the location of the body, approximately 7.5-8.5 days postmortem was estimated for the corpse at the time of its discovery.

    • "Although fewer sarcophagid species seem to colonize corpses than those of other families (mainly Calliphoridae), those that do colonize them do so under the most diverse environmental conditions. For example, they colonize corpses out and indoors, in sunny or shaded sites, as well as in wet or dry ones, and can be found associated with carcasses in both the early and late stages of decomposition (Byrd and Castner 2001; Romera et al. 2003; Sukontason et al. 2003a; Wyss and Cherix 2006; Al-Mesbah et al. 2011; Raghavendra et al. 2011; Cherix et al. 2012; González-Medina et al. 2012). What all of these papers have in common is that species identification is based on adults, and it is necessary to breed immature specimens in lab. "

    ABSTRACT: Sarcophagids are a large family of Diptera, with a worldwide distribution. They are related to decomposing organic matter and are very interesting for health science and in forensic cases since many species produce myiasis and occur in human corpses. This family is considered difficult to study, particularly with regard to their immature stages, to which little attention has been paid. Genus Sarcophaga Meigen, 1826 is composed of species of very similar morphology, making very difficult to distinguish. Knowledge of the immature stages of this genus is important because such stages occupy the greater part of the life cycle, so that establishing a basis for their identification will increase their usefulness in systematic and applied sciences. This contribution presents a detailed study of the morphological features, both external and internal, of the preimaginal stages of Sarcophaga (Liosarcophaga) tibialis Macquart, 1851, providing a taxonomical context for the correct identification of Liosarcophaga species of forensic interest in the Iberian Peninsula. Both light and scanning electron microscopy were applied. Complete descriptions of every stage are provided and illustrated, and their usefulness for species comparison, taking into account our uneven knowledge of morphologically immature stages of this subgenus, is indicated. Features of the cephalopharyngeal skeleton, such as the shape of the mouth hook and the intermediate and basal sclerites, and external morphology, such as the pattern of spinose band and anterior and posterior spiracles, proved useful for separating species. Finally, tentative identification keys based on light microscopy observation to distinguish S. (L.) tibialis from other species of forensic interest belonging to Liosarcophaga subgenus are proposed for every immature stage.

    ABSTRACT: Rabbit carcasses were used to compare rates of decomposition and associated assemblages of Diptera at four discernable habitat types in Kuwait; a country of a region with a paucity of such reference data. Carcasses in an urban habitat showed faster decomposition (as measured by percentage weight loss) than in agricultural, coastal or desert habitats, even with accumulated degree days (ADD) as the explanatory variable (t=2.73, df=34, p=0.010) to compensate for temperature differences. Taxa of Diptera at the four habitats became more similar as decomposition progressed, suggesting such differences between habitats were not marked. The occurrence of Chrysomyia megacephala and Lucilia sericata had not previously been recorded in Kuwait.

    ABSTRACT: Parasarcophaga (Liopygia) ruficornis is a well-known flesh fly species of medical importance, both as a myiasis-producing agent and fly seen in a forensic entomology context. This study performed a comprehensive literature review of this fly species, dealing with morphology, bionomics and medical involvement. Important characteristics used to identify P. ruficornis have been provided for both its third instar and adult for identification purpose in the future.
