Entomology is
study of insects and arthropods
study of dead organisms
study of soil
Forensic entomology is
study of insects
study of decomposition of matter
interpretation of insect evidence used in crime investigations
interpretations of decomposition of bodies
Select all that are correct:
To be classified as an insects, the organism must have
an abdomen.
a head.
eyes.
wings.
jointed legs.
Select all that are correct:
to be classified as an insect and organism must have
an exoskeleton.
a stinger.
a thorax.
a tail.
The correct order of an insect's stages of growth are:
egg, pupa, larva, adult
pupa, egg, larva, adult
adult, egg, pupa, larva
egg, larva, pupa, adult
Select all that are correct:
A forensic entomologist will
collect insect evidence
interpret insect evidence
interpret environmental conditions and other variables
use the information collected to estimate the PMI
PMI stands for
postmortem interval
postman intervention
post-medical interval
PMI is
the time between death and colonization by insects.
the time between death and discovery of the body.
the time between death and the funeral.
Sung Tz'u's writing in 1247 was important because
it used insect succession to estimate the death of a victim.
it used measurements of larva to identify the time of death.
it told of the first known use of entomoloty in solving a crime.
Bergenet d"Arbois was important in 1855 because
he used insect succession to estimate the death of a victim.
he used measurements of larva to identify the time of death.
he told of the first known use of entomoloty in solving a crime.
The 1935 case in Scotland was important because
Mearns used insect succession to estimate the death of a victim.
Mearns used measurements of larva to identify the time of death.
Mearns told of the first known use of entomoloty in solving a crime.
Technically, decomposition of a body begins
as soon as death occurs.
as soon as bugs begin eating the body.
as soon as a smell is detected.
as soon as a victim is identified.
Select all that are correct:
A decomposing body
releases apeneumones.
releases sulfur-based scents.
attract flies sometimes within a matter of minutes.
The PMI can be determined from fly maggots if the body is discovered
within 1 week of death.
within 1 year of death.
within 1 month of death.
anytime.
When using maggots to accurately determine PMI you must:
collect and grow samples to full size in order to identify the exact species
measure and record the size of maggots
take samples from the maggots stomachs (crops)
compare your data to other known maggot information
True or false: if a forencis entomologist can determine the age and developmental stage of maggots, the PMI will be accurate to a few days or less.
True
False
True or false: If more than 1 month has passed, then insects can not be used to establish a PMI.
True
False
Ambient variables referrs to
the amount of light at the crime scene.
the amount of water at the crime scene.
various environmental elements at the crime scene.
the location of the crime scene.
Click all the correct examples of ambient variables:
humidity
temperature
clothing of the victim
location
Insect succession is
not always useful in forensic entomology.
the study of different insects that inhabit decomposing bodies.
impossible to determine after 1 month of decomposition.
the predictable sequence in life cycles of species that inhabit decomposing bodies.
