Back 2

False

Front 3

In 1855, an entomologist used the concept of insect succession to determine which of four different tenants had murdered an infant that was found within the walls of a house. What was the name of this entomologist?

Back 3

Bergeret d'Arbois

Front 4

Within minutes of death, odor emitted from a dead body can be detected by blow flies from

Back 4

a mile away

Front 5

The blowfly lifecycle has six stages. How many larvae stages are included in these six stages?

Back 5

three

Front 6

True or False? The thick skin of the third instar is shed as the maggot prepares to become an adult fly.

Back 6

False

Front 7

In order to provide the most accurate estimate of postmortem intervals at a crime scene, which type of larvae should be collected?

Back 7

the oldest larvae

Front 8

True or False? One of the earliest cases to use insect evidence to solve a crime was described in the 1412 Chinese work by SUng Tz'u called "The Washing Away of Wrongs"

Back 8

False

Front 9

While processing a crime scene for insect evidence, what is the recommended number of maggots per mass to collect?

Back 9

50

Front 10

The number of hours at an adjusted average temperature, using Celsius degrees, that it takes an insect species to reach a particular stage of development is expressed in

Back 10

accumulated degree hours

Front 11

Name the two types of beetles that are likely to arrive early on a corpse.

Back 11

clown beetle and curinam carrion beetle

Front 12

Name the three body segments of an insect

Back 12

head, thorax, abdomen

Front 13

The arrival of which type of beetle is associated with the advanced stage of a dead body?

Back 13

hide beetle

Front 14

One type of insect typically arrives within minutes after death. Therefore this type of insect is considered to be timekeepers for postmortem intervals. Which type of insect is this?

Back 14

blowflies

Front 15

True or False? Blowflies do not lay eggs at night.

Back 15

True

Front 16

Flesh flies:

Back 16

arrive within minutes of death and deposit living larvae onto the flesh

Front 17

The lower limit threshold in the temperature below which growth and development cease for an insect.

Back 17

10 degree Celsius

Front 18

Blowfly eggs usually hatch in less than

Back 18

24 hours

Front 19

How do the temperature of feeding maggot masses compare to ambient temperatures?

Back 19

They have temperatures of 5 degrees F to 20 degrees F higher than ambient temperatures

Front 20

True or False? The decomposition stages of the body are fresh, bloated, decay, active decay, and dry decay.

Back 20

True

Front 21

Environmental conditions affect the growth of larvae. Consequently, in the collection of meteorological data, it is suggested that rainfall amounts be recorded for a period of:

Back 21

1-2 weeks before the victim's disappearance and 3 to 5 days after the body was discovered

Front 22

As a dead body decomposes, two gases putrescence and _____________________ are released that alert blowflies to a possible location to lay their eggs.

Back 22
