“…The opposite conditions have also been noted to retard insect growth significantly. Kotze, Villet and Weldon [36] have also studied the effect of temperature on development of the blow fly L. cuprina. They have studied the life cycle of L. cuprina at six constant temperatures from 18 º C to 33 º C to calibrate a thermal accumulation model of development for forensic applications.…”

Lucilia cuprina is one of the forensically important Calliphoridae fly. L. cuprina is a helpful resource at the crime scenes as well as a nuisance to sheep. It is known to be one of the first flies to occupy a corpse upon its death. Due to this, it has great importance in forensic field to find out post-mortem interval. In this study, the development of L. cuprina is studied in an incubator at different constant temperatures. Larvae of the L. cuprina were reared in an incubator at 20 º C, 25 º C, 30 º C, 35 º C, and 40 º C. During study the developmental data, temperature and relative humidity of the rearing room as well as weight, length of the larvae were recorded from the time the larvae were collected until the adult flies emerge out.Results obtained show that development of the L. cuprina was slow at lower temperature. At the high temperature, developmental rate was fast. At low temperature L. cuprina attained greatest body weight whereas at high temperature there was a decrease in the weight. When flies were reared at 40 º C the development of the fly was much more rapid but slight mortality was observed. Above study shows that temperature plays a very important role in the development of L. cuprina. For the correct estimation of post-mortem interval this study is very useful, because each dipteran fly has its own developmental period with respect to temperature and region.

“…As temperatures rose from 24 º C, growth was increasingly compromised, and the physiological stress of developing at more extreme temperatures was evident in decreased survivorship [36].…”

“…Later, however, the individual was confirmed to have been deceased for at least 12 days [22]. Additional studies show that higher temperatures also alter development, by increasing Lucilia cuprina larval development at peak temperatures of 24°-27°C [21].…”

“…Recording ambient temperature where a corpse is found is pertinent in determining PMI, especially with bodies found indoors where the temperature is much less likely to fluctuate [21]. It is accepted practice to place a corpse into a morgue refrigerator post discovery and prior to autopsy or examination.…”

“…Based on conventional forensic methods, the time of death can be expressed in days or weeks during putrefaction. However, based on rates of growth of larvae, estimations of postmortem intervals can be sufficiently clear to express in hours [2][3][4]. Forensic entomology is rarely referred to in Turkey.…”

Every material in crime scene, which is considered as evidence, has to be examined by forensic authorities. This can contribute to solve cases and thus to justice. However, entomological evidence seems to be disregarded by some public prosecutors, crime scene investigators and forensic specialists. Disregard for entomological evidence and even simple, unimportant mistakes made during collection and transfer of specimens, identification of species and estimation of post-mortem interval may interact with each other and prevent one from reaching accurate results. The aim of this study was both to identify these lapses and emphasize appropriate precautions to prevent them. Entomological material collected from seventeen cases and their crime scene reports and photographs were examined. The entomological evidence could be seen easily on all of the cases, but mostly there were not any records of entomological evidence in their crime scene investigation (CSI) protocols. In our cases, the particular problem was measuring ambient temperatures. It can be recommended that judges, public prosecutors and lawyers, the most important forensic authorities, should be informed about disregard for entomological evidence and mistakes concerning their collection and transfer. This is the only way to enable entomological examination results to be accepted as evidence in courts.
