“…C. albiceps flies were identified at the Biology Department, Faculty of Science, and were reared in the laboratory for ten generations. Flies were placed in polypropylene breeding cages (45 × 30 × 20 cm), and adults had access to food ad libitum; the diet consisted of skimmed powder milk and 10 g of sugar in 100 ml of water in Petri dishes (Al-Shareef and Al-Qurashi 2016;Salazar-Souza et al 2019). Larvae were placed in beakers within transparent boxes containing sand and sawdust to prevent the postfeeding larvae from escaping.…”

Background Chrysomya albiceps (Wiedemann, 1819) (blowflies), family Calliphoridae, is important in forensic entomology, where the minimum and maximum postmortem intervals (PMI) are estimated on the basis of the developmental stages of Diptera larvae that consume dead tissue. The present study was designed to estimate the effects of different ambient temperatures (20, 25, and 30 °C) under controlled laboratory conditions on the developmental stages of C. albiceps from the Jazan region, Saudi Arabia. Results The present study showed that the larval body weight and length were significantly increased when larvae were reared at 30 °C compared with corresponding values at 24 h, 48 h, and 72 h at rearing temperatures of 20 °C and 25 °C; however, the weight and length were significantly decreased compared with corresponding values at 96 h at 20 °C and 25 °C. The pupation time was inversely related to the rearing temperature, occurring at 144, 124, and 120 h at rearing temperatures of 20 °C, 25 °C, and 30 °C, respectively. The pupal weight and length were significantly increased in larvae reared at 30 °C compared with those reared at 20 °C and 25 °C. At 20 °C, 25 °C, and 30 °C, larval durations of 5.00, 5.00, and 4.00 days were recorded, respectively. Pupae and adults showed gradual decreases in life stage durations, at 6.00, 5.30, and 4.80 days in pupae and 20.00, 18.70, and 16.90 days in adults, with increasing rearing temperatures. Average adult longevity at 30 °C (194.40 h) was significantly less than adult longevity at 20 °C (216.00 h) and 25 °C (204.60 h). The results showed an inverse relation between durations of developmental stages and rearing temperatures. Conclusions Insect laboratory colonization for the determination of biological characteristics of insects is economically viable for forensic entomology and as a technique for evaluating insect evidence.

The accurate estimation of the time of death (Post-Mortem Interval, PMI) is of great importance when reconstructing the actual events at a crime scene following the recovery of a body. The reliability of the PMI is vital to validate witness statements and suspect alibis. The PMI estimation based on insects collected from remains relies on two fundamental principles. Firstly, the development of an insect is proportionate to its surrounding environmental condition, and secondly, colonization by insects and other arthropods typically occur according to predictable sequences subjected to seasonality, environment in which the decomposition takes place, and the possible presence of xenobiotics in the food substrate (e.g., drugs). Dipteran species of the family Calliphoridae are the most common species colonizing a corpse and carcass, and a large body of research in entomology is focused on their developmental data. Such data is used forensically to estimate the PMI via three types of calculation: accumulated degree day/hour, table of growth, and isomegalen/isomorphen diagram. Much of this research has been documented during the 20th century, in different countries, using different experimental designs and analyses. This review tabulates development data obtained from 74 manuscripts published between 1933 and 2021 for five cosmopolitan blowfly species associated with the early stages of decomposition during the warmer seasons: Chrysomya megacephala, Ch. rufifacies, Ch. albiceps, Lucilia sericata, and L. cuprina. This review highlights the importance of establishing a standardized protocol to conduct future development studies and maintaining a system for retrieval of this data for future PMI calculations.

In forensic entomology, research focused on sarcosaprophagous flies, but the sarcosaprophagous beetles, as important “forensic indicator species” of late-stage PMI in cadaver decomposition, received less attention. To increase attention on, and use and understanding of, sarcosaprophagous beetles in forensic entomology, this paper presents a bibliometric analysis of the available relevant literature. The occurrence frequency of beetle families and species from succession studies, actual cases, and experiments were calculated and illustrated using graphs. As a result, a total of 14 families and 1077 species associated with carcasses were collected, with Staphylinidae being the most frequently recorded among the families, and Necrobia rufipes (Fabricius, 1781) (Coleoptera: Cleridae) being the most frequently recorded species. In addition, a brief introduction of the cadaver-related beetles of each family is given, and research on the species identification of the immature stages, age estimation of the immature stages, and estimation of the arrival time of sarcosaprophagous beetles are discussed and prospected. This work will aid in the increased use of sarcosaprophagous beetles in forensic science practice in the future.
