Introduction to Forensic Entomology
Forensic entomology is the study of the application of insects and other arthropods in a criminal investigation. Insects or arthropods are found in a decomposing vertebrate corpse or carrion. These insect colonizers can be used to estimate the time of death i.e., the time interval between death and corpse discovery, also called postmortem index (PMI), movement of the corpse, manner, and cause of death, and association of suspects at the death scene.
Let's look at the questions and their answer.
Ques 1. Forensic entomology can tell us about which of the following
a) post mortem interval (PMImin)
b) victim was poisoned/drugged
c) movement of the body after death
d) all of these
Answer – d) all of these
Ques 2. The oldest known case of forensic entomology was published by
a) Francesco Redi
b) Song Ci
c) Hermann Reinhard
d) Jean Pierre Megnin
Answer –a) Francesco Redi
Ques 3. A corpse was found to contain eggs and first stage maggots of the blow fly. How much time is estimated since death?
a) 12h
b) 8h
c) 6h
d) 24h
Answer – d) 24h
Ques 4. The type of insects used in forensic analysis is
a) Oligophagous
b) Necrophagous
c) Endophagous
d) All of these
Answer – b) Necrophagous
Ques 5. The oldest known handbook of entomology was published in 1247 by
