Optimising crime scene temperature collection for forensic entomology casework
The study of insects and other arthropods in a medico-legal context, also known as forensic entomology, is an essential tool in legal cases, especially in death enquiries [1]. Traditional forensic pathology methods for time of death estimation, using post-mortem changes such as rigor mortis, reach their limits within 48 –72hours after death [2]. At that point forensic entomology becomes particularly important as knowledge of insect biology, ecology and identification can provide information such as post-mortem body relocations, environmental conditions at death occurrence and, most importantly, estimation of a mi nimum p...

Life history data on the fly parasitoids Aleochara nigra Kraatz and A. asiatica Kraatz (Coleoptera: Staphylinidae), and their potential application in forensic entomology
Abstract: Knowledge of the developmental time of the immature stages of necrophagous flies has been the main tool for estimating minimum post-mortem intervals (min PMIs) in forensic entomology. Many parasitic insects can alter the development of immature stages of flies and thus affect min PMI estimates. The larvae of most species of Aleochara rove beetles are ectoparasitoids of the pupae of cyclorrhapha flies. Among them, some species that parasitise necrophagous flies may have forensic importance. Two Taiwanese Aleochara species, A. nigra and A. asiatica, which visit carrion sites were studied herein. All five necrophago...

Do necrophagous blowflies (Diptera: Calliphoridae) lay their eggs in wounds? Experimental data and implications for forensic entomology
This study investigate the factors that affect the oviposition sites of Lucilia sericata (Diptera: Calliphoridae) (Meigen, 1826), a very common blow fly species of forensic interest. Blowflies (Diptera: Calliphoridae) have an highly developed olfactory system that allows them to detect corpses at a great distance [1–4]. It is frequently reported in forensic entomology manuals that once on the cadaver, blowflies lay their eggs in natural orifices and wounds [5–10]. The presence of other eggs, larvae or adult individuals can also act as an attractive signal to gravid females and can increase the likelihood of ovipositio...

EFFECTS OF TEMPERATURE AND DIET ON BLACK SOLDIER FLY, Hermetia illucens (L.) (DIPTERA: STRATIOMYIDAE), DEVELOPMENT
Forensic entomology is the application of insect or other arthropod evidence to legal investigations [1]. While the first recorded use of forensic entomology dates back to the 13th century in China, it was only in the late 1800s that interest in this field gained momentum [2]. Currently, forensic entomology is organised into three principal areas: urban, stored products and medicolegal entomology [3,4]. Medicolegal entomology concentrates on insects associated with human or other animal remains, and may aid in several aspects of an investigation such as movement of a body postmortem, toxicological analysis, and indication of trauma [5–7].

Identification of sarcosaprophagous Diptera species through DNA barcoding in wildlife forensics
Abstract: In recent years, forensic entomology has been applied in wildlife crimes, such as neglect cases, animal cruelty and illegal poaching. Likewise in human death investigations, in which insects can help to provide information about postmortem interval (PMI) and corpse transfer, entomology may be an important source of information in animal murder suspicion. The use of insects in forensic context relies primarily on its identification at the species level. To overcome some problems of morphological determination, molecular identification has gained relevance and has been applied frequently in forensic areas. Cytochro...

Estimating postmortem interval using RNA degradation and morphological changes in tooth pulp
In this study, time-dependent differences in RNA decay rates were examined to extend the time frame over which early PMI estimates can be made. Comparing the decay rates of a large, labile segment of β-actin RNA and a smaller, more stable, non-overlapping segment of the same RNA from tooth pulp, we were able to estimate PMI values of pigs buried within a shallow grave for up to 84 days. This compares favorably to an estimate of PMI using insect data. Full skeletonization and loss of insect activity was observed by day 28 of our study. In addition to differences in RNA decay rates, morphological changes were observed in th...

Using Bacterial and Necrophagous Insect Dynamics for Post-Mortem Interval Estimation during Cold Season: Novel Case Study in Romania
Forensic entomology is a widely recognized, location dependent discipline used in many forensic investigations, particularly for the minimum post-mortem interval (PMImin) estimation [1–4]. Insects have served as physical evidence in numerous cases around the world, such as in the United Kingdom [5], United States of America [6], Canada [7], Italy [8] and Brazil [9], both during the early and extended post-mortem period [10]. Yet, in Romania, a country in southeastern Europe comprising approximately 240,000 square kilometers and 20 million inhabitants, forensic entomology is not used as an investigative tool nor do police...

The potential of forensic analysis on human bones found in riverine environment
This article aims to demonstrate the potential of forensic examination and analyses (DNA, toxicology, diatoms and entomology) on a set of bones recovered from a river in Strasbourg and the possibility to trigger identification of the victim and circumstances of death despite the state of decomposition and incompleteness of remains.

Temperature-dependent appearance of forensically useful beetles on carcasses
Abstract: Estimating the pre-appearance interval (PAI) of carrion insects from temperature is a new and promising improvement of entomological methods for post-mortem interval estimation. In order to use this approach in casework, a taxon should demonstrate a close relationship between PAI and temperature. In this article we test this relationship in selected species of beetles, namely Thanatophilus sinuatus Fabr., T. rugosus L., Necrodes littoralis L. (Silphidae), Necrobia rufipes De Geer, N. violacea L. (Cleridae), Dermestes frischii Kug. (Dermestidae), Creophilus maxillosus L., Philonthus politus L., Ontholestes murinus...

Thermogenesis in decomposing carcasses
This study suggests that bacterial metabolism plays a significant role in carcass thermogenesis, and that maggot masses, while contributing to localised heating within the carcass, may have less of a role in elevating carcass temperatures than previously assumed.

Molecular differentiation of Central European blowfly species (Diptera, Calliphoridae) using mitochondrial and nuclear genetic markers
The Calliphoridae family is considered an important source of information involved in medical, veterinary and forensic investigations [1,2]. It may be used to detect abuses, abandonment or neglect in addition to its usefulness in murder caseworks [3–5]. Blowfly species are commonly associated with carcass decomposition, necrotic tissues in wounds (superficial myiasis) and the presence of feces or urine in skin (rectal or urogenital myiasis) [6]. The current aging population and the global economic crisis may result in a change in the scope of Forensic Entomology, with an increasing number of deaths in which the period of...

The first report of Telomerina flavipes (Meigen, 1830) (Diptera, Sphaeroceridae) in a forensic case, with redescription of its pupa
The contribution of Forensic Entomology to forensic practice has been widely documented and in some cases has provided interesting results on the fauna related to corpses (e.g. [1–8] among many others). The most interesting application to forensic practice deals with the estimation of a minimum post-mortem interval (PMImin) on the basis of entomological evidence recovered from the corpse or the forensic scene. Such estimation can be made taking into account the larval development of the species feeding on the corpse, as well as the succession model of the sarcosaprophagous fauna.
