bf 1 what are the 3 D's in the body farm?
death, decay, and decomposition
bf 2 what information has the body farm provided?
by the body decay, you can tell how much time has passed since the death
bf 3 where is the body farm located?
university of Tennessee, Knoxville
bf 4 why was Mann experimenting with dog decomposition?
he was skeptical that a dog could have the same decomposition pattern as a human
bf 5 what is significant about the "ring of hair"
proof that animal decomposed in the exact spot
bf6 according to mann, what 6 factors determine the rate at which a body decays?
1. penetraiting 2.rainfall 3. surface 4. humidity 5. access to insects 6. ambient temperature
bf 7 what is bloating? how does it affect decomposition?
internal gases in the abdomen
bf 8 name three stages of decomposition
fresh, bloated, dry
bf 9 define marbling
the vein fill with bacteria and the turn green and black
bf10 do skin and hair contain live cells?
no., they are dead cells
bf 11 what is hair mass?
head hair in a clump
bf 12 how would you get fingerprints off a badly decomposing body?
cut the hand off or remove the "glove"
bf 13 who is bill bass
established body form
vp 1 what kind of inforamtion is provided on the blow fly life cycle handout
the blowfly cycle has six parts: the egg, three larval stages, the pupa, and adult. it tells how much time it takes for each stage of a blowfly and how it helps determine time of death in human bodies
vp 3a how many hours does it take for a green bottle fly egg to become an adult fly?
345 hours (14 days and 9 hours)
vp 3d which of these are constant or variable -life cycle stages, temperature, time between the life cycle stages, ADH
life cycle stages- constant
time between the life cycle stages- variable
vp 4 describe in your own words how insect life cycles can be used in estimating the time of death
each stages of life of the bug takes a certain amount of time. by telling how old the big is and how long it was in the dead body you can see how long the body has been dead for
vp 1.2 list three top categories of information that may affect entomological factors
temperature, precipitation, wind, and weather
vp 2.2 would wind and precipitaition affect entomological behaviors highly, moderately, or not much?
wind would highly affect it because the numbers will change because wind changes the temperature. precipitation would only affect it a little since it doesn't change any of the big factors
ec 1 what tasks was Dr. Krinsky asked to hellp with in the 1986 murder case
he helped determine the time of death using weather evidence
ec 2 what types of evidence and information did Dr. Krinsky gather?
ec3 what kind of observations did Dr. Krinsky make about the collected insect evidence?
that maggots were only foun fon the lower body
ec4 how did dr. krinsky process the blow fly puparia collected from the carpet on september 22, 1986? why?
he measured the blow fly which helped determine the larval stage. this then showed the life of the maggot and determined the time of death
ec5 what are some factors that affect the insect life cycle
temperature, weather, and sunlight
ec6 describe in your own words how insect life is applied in estimating the time of death
the life cycle of an insect can determine the time of death of a body
Five stages of Decomposition fueled by insect activity
4. post decay
what is the order of insects that arrive to a dead body
• Blow flies (bottle) - few minutes
• Flesh flies- few minutes - day or two
• Rove beetles, soldiers flies- feed on developing maggots
• Cheese skippers, scuttle flies- feed on fermented protein of the later stages of decomposition
• Mites- like cry cadaver
• Clothes moths and spider beetles- like completely desiccated remains
rq What is forensic entomology?
the use of the insects and other arthropods that feed on decaying remains to aid legal investigations
