    Forensic Entomology

    Forensic Entomology is that special associated distinctive discipline of Forensic Science that deals with the assorted aspects of an insect’s or a maggot’s life cycle so as to assess the time since death. Besides the actual fact that it's one among the distinctive applications of the Sciences technicalities, it’s another side is that it's a way-back best-known Science to the human civilization.


    The history of Forensic Entomology rests all the approach back to the thirteenth century. The earliest best-known and recorded case of Forensic Entomology comes from the medieval China. Within the year 1325, a Chinese attorney named Sung T’su wrote a text book on criminal investigations, referred to as “The Washing Away of Wrongs”. During this book, T’su recounts a murder that went on close to the rice field. The victim has been repeatedly slashed by a sharp edged weapon and investigators suspected it to be a reap hook or a sickle, a typical tool usually employed in rice harvest. The native official then asked all the farmers to come up with their sickles. Though all the sickles looked clean, nonetheless one among the sickles attracted hordes of flies. The flies have the power to sense the residue of blood and tissue invisible to the human eye. Once being confronted by the jury of flies, the slayer confessed the commission of the crime. In spite of sensing the residues of blood and tissue, insects and maggots are of nice facilitate in deciding the time go on since the death of the deceased.


    It is a best-known irrefutable fact that insects and maggots are of a big help to a Forensic Entomologists in deciding myriad factors associated with the death of a private and therefore will offer several links that might ease the complete method of criminal investigation, thereby providing a final conclusion to the case. A number of the essential applications of Forensic Entomology are- determination of your time since death or Post-mortem Interval (PMI) is of huge importance during a crime investigation, as this could offer a robust and far more conclusive result in the complete case. An intensive study of the maggots and therefore the varied stages of its life cycle will terribly clearly offer ends up in a Forensic Entomologist in assessing rather more approximate PMI.


    Generally, blood and varied alternative tissues bear a laboratory analysis to see the presence of poisons and its levels within the body. However in few cases wherever body remains undiscovered for an extended duration, then maggots are collected and brought to the laboratory for entomo-toxicological studies as a result of the advanced stage of decomposition within the body where assortment and preservation of body viscera becomes an impossible task. This entomo-toxicological studies of the maggots facilitate in the assessment of poison levels within the body.


    Insects’ species are continuously restricted to a limited region or surroundings. The body gets settled shortly once the onset of decomposition. Just in case if the body gets stirred by some external force, then it gets re-colonized once more relying upon the region and therefore the individual environmental issue. But, this secondary colonisation may dissent from the initial colonisation, thereby providing a clue that the body was resettled in a while.


    This course outline would inculcate within the students an ability to view every miniscule factors present at the spot, where crime was conducted. In addition, they would also be able to analyse the sequence in which the insects colonize a corpse, and its evidentiary value in the court room.
