Forensic entomology


Forensic entomology is the scientific study of the invasion the succession pattern of arthropods with their developmental stages of different species found on the decomposed cadavers during legal investigations. It is the application and study of insect and other arthropod biology to criminal matters. It also involves the application of the study of arthropods, including insects, arachnids, centipedes, millipedes, and crustaceans to criminal or legal cases. It is primarily associated with death investigations; however, it may also be used to detect drugs and poisons, determine the location of an incident, and find the presence and time of the infliction of wounds. Forensic entomology can be divided into three subfields: urban, stored-product and medico-legal/medico-criminal entomology.

Historically, there have been several accounts of applications for, and experimentation with, forensic entomology. The concept of forensic entomology dates back to at least the 13th century. However, only in the last 30 years has forensic entomology been systematically explored as a feasible source for evidence in criminal investigations. Through their own experiments and interest in arthropods and death, Sung Tzu, Francesco Redi, Bergeret d’Arbois, Jean Pierre Mégnin and the physiologist Hermann Reinhard have helped to lay the foundations for today's modern forensic entomology.

Sung Tzu (also known as Sung Tz’u) was a Judicial Intendant who lived in China 1188-1251 AD. In 1247 AD Sung Tzu wrote a book entitled Washing Away of Wrongs as a handbook for coroners. In this book Sung Tzu depicts several cases in which he took notes on how a person died and elaborates on probable causes. He explains in detail on how to examine a corpse both before and after burial. He also explains the process of how to determine a probable cause of death. The main purpose of this book was to be used as a guide for other investigators so they could assess the scene of the crime effectively. His level of detail in explaining what he observed in all his cases laid down the fundamentals for modern forensic entomologists and is the first recorded account in history of someone using forensic entomology for judicial means.
