The Study of Insects for Forensic Applications
International Journal of Research in Advent Technology
Forensic entomology is the study of insects in the successive pattern of anthropods with the developmental stages of different species in the dead body or decomposed cadavers for criminal and legal matters. It is the study of anthropod biology. It also involves the application of study of anthropods including insects, arachnids, centipedes, millipedes and crustaceans in criminal cases. It is used to detect the death composition of drug and poison activity in the particular incident and to find the presence or absence of insects at the time of the infliction of wounds. Forensic entomology is used in estimating the minimum post mortem time interval.
The use of insects in forensic investigations: An overview on the scope of forensic entomology
Journal of Forensic Dental Sciences, 2011
Forensic entomology is the study of insects/arthropods in criminal investigation. Right from the early stages insects are attracted to the decomposing body and may lay eggs in it. By studying the insect population and the developing larval stages, forensic scientists can estimate the postmortem index, any change in position of the corpse as well as the cause of death. Forensic odontologists are called upon more frequently to collaborate in criminal investigations and hence should be aware of the possibilities that forensic entomology have to offer and use it as an adjunct to the conventional means of forensic investigation.
Role of insects in environment with special reference to forensic science
Journal of entomology and zoology studies, 2020
Insects are the dominant group of animals on earth today. They occur practically everywhere and far outnumber all other terrestrial animals taken together. They create the biological foundation for all terrestrial ecosystems. They cycle nutrients, pollinate plants, disperse seeds, maintain soil structure and fertility, control populations of other organisms, provides food besides having great utility in the field of medicine and forensics. Forensic entomology is a science, which applies knowledge of insects (and other arthropods) to civil proceedings and criminal trials. The applications of Forensic Entomology are numerous, encompassing any situation that may involve an interaction between insects and other arthropods, and the law. Therefore, the utility of the field includes in the areas like; urban, stored product and medico legal. The principle underlying this science is to establish the time of death, known as postmortem interval (PMI) by knowing the life cycle of insect species...
Forensic Entomology:an overview
Crime, Security and Society, 2018
Insects are the most important, in terms of number and diversity, group of animals on the earth. Insects have colonized all the world's environments and are associated with both human life and death. Although their economical and sanitary importance is well documented, in the past few years they have been used also in a forensic context. In forensic entomology, necrophagous insects have proved useful in; studying postmortem interval (PMI), postmortem transfer (the movement of a body from one location to another after death), presence of drugs or poisons, and in identifying the victim and/or the suspect. Many species can be used to estimate the minimum PMI (mPMI), according to the stage of cadaver decomposition, body exposure, geographical region, and season. The most important British flies of forensic interest are described.

Necrophagous insects are important in the decomposition of cadavers. The close association between insects and corpses and the use of insects in medicocriminal investigations is the subject of forensic entomology. The present paper reviews the historical background of this discipline, important postmortem processes, and discusses the scientific basis underlying attempts to determine the time interval since death. Using medical techniques, such as the measurement of body temperature or analysing livor and rigor mortis, time since death can only be accurately measured for the first two or three days after death. In contrast, by calculating the age of immature insect stages feeding on a corpse and analysing the necrophagous species present, postmortem intervals from the first day to several weeks can be estimated. These entomological methods may be hampered by difficulties associated with species identification, but modern DNA techniques are contributing to the rapid and authoritative identification of necrophagous insects. Other uses of entomological data include the toxicological examination of necrophagous larvae from a corpse to identify and estimate drugs and toxicants ingested by the person when alive and the proof of possible postmortem manipulations. Forensic entomology may even help in investigations dealing with people who are alive but in need of care, by revealing information about cases of neglect.
Forensic entomology: Applications and limitations
2011
Forensic entomology is the science of collecting and analysing insect evidence to aid in forensic investigations. Its main application is in the determination of the minimum time since death in cases of suspicious death, either by estimating the age of the oldest necrophagous insects that developed on the corpse, or by analysing the insect species composition on the corpse. In addition, toxicological and molecular examinations of these insects may help reveal the cause of death or even the identity of a victim, by associating a larva with its last meal, for example, in cases where insect evidence is left at a scene after human remains have been deliberately removed. Some fly species can develop not only on corpses but on living bodies too, causing myiasis. Analysis of larvae in such cases can demonstrate the period of neglect of humans or animals. Without the appropriate professional collection of insect evidence, an accurate and convincing presentation of such evidence in court will be hampered or even impossible. The present paper describes the principles and methods of forensic entomology and the optimal techniques for collecting insect evidence.
Forensic entomology: A novel approach in crime investigation
GSC Biological and Pharmaceutical Sciences
Forensic entomology is an application of studies related to insects and other arthropods in legal matters. Depth knowledge and experience of the biodiversity, biology, ecology, and behavior of forensic insects found on a human corpse or at a crime site, can provide information about time since death, location of the crime, and in some cases cause of death. Although forensic insects are used in crime investigation for three to four decades, it aroused recently as a very popular and independent branch of forensic science in crime investigation. While observing and examining insects on a corpse, knowledge of regional insects’ assemblages and their population dynamics play an important role in medico-legal entomology for an efficient criminal investigation. Forensic entomology has three components, named as urban, stored products, and medico-legal. As different groups of insects are attracted to different stages of decay, forensic insects invade the corpse in a typical sequence. The typ...
A Comprehensive Overview of Forensic Entomology
INTERNATIONAL JOURNAL OF ETHICS, TRAUMA & VICTIMOLOGY, 2021
Arthropods comprise the most ubiquitous species globally that play a key role in the decomposition process of a corpse. The entomological analysis of species commonly associated with carrion can provide valuable insights in investigations which forms the basis of Forensic Entomology. Since historical times, entomological data has aided in resolving numerous medico-criminal cases. Estimation of post-mortem interval by careful analysis of insect fauna associated with a decaying corpse is the most prominent application of Forensic Entomology. However, the conditions surrounding a decomposing corpse are not always optimum, and the rate of decomposition is influenced by multiple factors that need to be considered by forensic entomologists. The present article provides a comprehensive overview of the field of Forensic Entomology, its various applications, limitations and advances through time.
Forensic Entomology: A Comprehensive Review
Advancements in Life Sciences, 2019
etermination of post mortem interval is done with various methods depending upon the condition of the dead body and the circumstances in which it is found. Ruling out foul play in unnatural deaths has been an enigma of a sort for forensic pathologists and scientists all over the world. The methods to determine the cause and manner of death keep on emerging with ongoing researches in the fields of forensic sciences. Many methods have been devised to determine cause, manner and specifically time since death. Forensic entomology is one such field that aids in determination of time since death, especially in putrefied corpses found in different habitats in mysterious unknown circumstances. The field keeps on emerging with the advent of new techniques on molecular level, including DNA analysis and identification based on entomological data that has diversified over the years. The standards and guidelines for entomological data collection and processing needed for implication on the crime scene must be revised now and again for assistance of crime scene investigators, scientists, entomologists and pathologists. Various factors must be considered while processing entomological data that affect post mortem intervals. The keen study of life cycles, groups of similar insects, valid and standard methods of insect collection, breeding and identification can give a lead on cause, manner, time, place and circumstances of unknown or unnatural deaths.
