What is it?
The word entomology comes from two Greek expressions entomon and nology, whose meaning is insect and study respectively. So, entomology is the science that studies the insects.
So, what is forensic entomology?
Forensic Entomology is the science that, studying the insects of a bod
y, identifies the causes of death of human beings. It is used with time of death up to 3 days, as there other methods equally effective when the range is shorter. After three days, the evidence provided by insects are often more valuable, and sometimes the only method of determining the PMI (post mortem interval).
Some applications ...
This area of forensic science has several applications, although it is not very used. It serves to:
- Know the place of death - You can check the place where the death occurred through geographic distribution, natural habitat and biology of the species collected at the scene of death.
- Find the mecanism of death -There are drugs and toxic substances on the body that affect the speed of development of necrophagous insects. Some affect the development of larvae and decomposition of the body, other prevent the colonization of the body by some necrophagous insects.
- Calculate the PMI.
- Know if there were drugs involved - it is possible to identify the origin of some type of drug based on the identification of insects accompanying the drug, which at the time of pressing the plant were retained there, tracing the route of trafficking through the geographical distribution of the same .
- Know if there was abuse - it is possible to determine the number of days during which the baby was deprived of care, hygiene, relying on the determination of the age of the larvae of flies found in beds.
