Q

Detritivore

A

Internally breakdown dead organic waste

Physically shred waste

In warmer environments they breakdown more things because they are more active

Insects and arthropods are detritivores

Q

Carrion beetle adaptations

A

Release secretions on dead organism, basically marking it and preventing other organisms from eating it

This allows their larvae to eat it instead

Q

Degree days

A

The degrees over a temperature threshold that accumulate over a day

Has a lower and upper threshold, falling between the two allows for development

22
Q

Instar

A

Stage of development

23
Q

Voltinism

A

Number of generations per year

Warmer temps allow for faster development

24
Q

Bivoltine

A

Make 2 generations per year

25
Q

Multivoltine

A

Make more than 2 generations per year

26
Q

Forensic entomology

A

Using insects in the field of criminology

27
Q

Medicolegal Forensive Entomology

A

Insects are used to for cuts or other things in identifying homicides

28
Q

Role of forensic entomologists

A

Finding timings of certain things in forensics by looking at life cycles of insects in dead bodies

Can also tell if body is moved by the type of insects

Can also tell if someone is poisoned

29
Q

What affects insect development most

A

Temperature

30
Q

Insects can also indicate

A

The type of changes a dead body has undergone

31
Q

Postmortem interval

A

Telling the time of death by determining when arthropods enter a corpse

32
Q

Forensic entomologists use

A

Degree days to find the stage of insect development and time of death of the corpse

33
Q

Degree day models are used

A

When bodies are still fresh

34
Q

Step 1

A

Collect maggots or other first colonizers

35
Q

Step 2

A

Identify species to find developmental time of organism to find when the body died

36
Q

Step 3

A

Estimate developmental stage

37
Q

Step 4

A

Obtain climate data where the body was found

38
Q

Step 5

A

Calculate Degree-days to find Post-Mortum-Interval

39
Q

Step 6

A

Estimate when eggs were deposited on corpse

40
Q

Insect succession

A

Change in species composition in relation to the stage of a corpse

41
Q

3 main groups of arthropods that colonize a corpse

A

Necrophages

Predators

Incidental organisms

42
Q

Time of insect arrival is dependent on

A

What type of food is available (IE tissue or bones)

43
Q

Predators

A

Feed on necrophages and the corpse

44
Q

Incidental organisms

A

Use things on the corpse or near it for habitat and shelter

45
Q

The first stage of decomposition

A

Fresh

compounds are released from the corpse that attract necrophages

Maybe some flies that deposit eggs on the corpse

These maggots feed on the dead tissue

46
Q

The second stage of decomposition

A

Putrefaction

Initial species are joined by other species of flies and beetles as well

47
Q

The third stage of decomposition

A

Black putrefaction

Maggots that have developed exit to pupate in the soil nearby

Adult flies leave as corpse is unsuitable for maggot development

Beetles dominate

48
Q

The fourth stage of decomposition

A

Butyric fermentation

Butyric acid is produced and there is little flesh at all

No more flies only beetles and some mites

49
Q

The fifth stage of decomposition

A

Dry decay

little remains of the corpse other than bones and some dry skin

Most beetles leave and incidental organisms arrive

50
Q

If insects are drawn away from the mouth

A

It is the sign of a wound that they are drawn to

51
Q

Insects can also tell if the body has

A

Drugs by bioaccumulation of maggots

52
Q

Bodies that are frozen or buried

A

Are difficult for necrophages to reach

53
Q

Forensic entomology can only be used

A

In warm temps
