• Presence of Rigor Mortis
• Stages of decomposition
• Insect behavior and lifecycles
Term

caused swollen belly syndrome
Malnourished people
Term
Onchocerciasis
Definition
• River blindness
• Microfilaria
• Lives up to 14 years in body
• Spread by the bite of infected black flies
Term
Dracunculiasis
Definition
• Guinea worm
• Threadlike parasitic worm that grows and matures under the skin
• Looks like hemp rope under skin
• Hermaphroditic worm that mates with itself
• Get infected when they drink standing water containg a tiny water flea
Term
3 categories of Forensic Entomology
Definition
Urban
Stored Product
Medicolegal
Term
Process of death: Somatic death
Definition
o Organism is irreversibly unconscious
o All cellular activity does NOT stop at this point
Term
Process of death: Cellular death
Definition
o Individual cells/organs cease functioning at varying rates
o When discussing decay, this is important
Term
What are the environmental factors of forensic entomology?
Definition
Temperature, rain/water, exposure
Term
Rigor Mortis
Definition
Stiffening of body muscles due to lactic acid
Term
Inital stage of decomposition
Definition
• First stage
• Body appears normal on outside
• Is decaying on inside (cellular death)
• Bacteria
• Nematodes
• No associated smells
• Flies
• Begun laying eggs on the body, in the ears, nose, mouth, and anal. Lay eggs in orafices.
Term
Stages of Decomposition
Definition
• Initial
• Putrefaction
• Black putrefaction
• Butyrie
• Dry decay
Term
Putrefaction
Definition
2nd stage of decomp, • Body bloated
• Pressure forces fluids and by-products out
• Associated odor of decay
• Flies
• Wasps
• Beetles
• Most colorful insect we know occur in these kinds of environments
Term
Black Putrefaction
Definition
• Third stage
• Gases have escaped
• Flesh creamy consistency
• Odor of decay very strong
• Insects prime factor in decay
• Insects cosume bulk of flesh and seepage
• Several generations of maggots
• Mature 3rd stage wander off to form pupae
• Predatory maggots more common
• Pioneer flies not attracted
• Increase in necrophagous/predaceous beetles and parasitoid wasps
Term
Butyrie
Definition
• Fourth stage
• Body drying out
• Bits in contact with ground mold
• Cheesy odor
• Major insect succession
• Cheese Skipper – immature stage that is important
• They can jump 6x body length
Term
Dry decay
Definition
• fifth stage
• roaches show up
• only insects feeding on hair remain
• mostly clothes moths and roaches
• feed on dry, dead skin
Term
Arthropod-Vectored Human Diseases Cycle
Definition
• pathogen (disease)
• vector (carrier)
• intermediate host (sometime)
• human host
• 1 of every 6 people affected by an insect carried disease
Term
What is entomophagy?
Definition
Eating insects
Term
What is the ECI?
Definition
• Efficiency of conversion of ingested food – the amount of weight an animal gains per weight of food an animal eats
Term
Worldwide, what determines the most commonly consumed insects?
Definition
Those that are in large quantities such as the migratory locust or termites
Term
Roman cossus
Definition
• A grub or caterpillar of uncertain identity that in Rome was considered a delicacy after fed flour
Term
Bushmen's rice
Definition
Ant with long body and black head that is eaten
Term
Maeng dana
Definition
• A giant water bug that is available for sale at markets and in fact has made an appearance in California in import stores
Term
Most insect eating in the US
Definition
Missiissippi
Term
What did V.M. Holt do in 1885 that promoted entomophagy?
Definition
• Published a book titled Why Not Eat Insects?
• Argued that plant-feeding insects in particular were clean, nutritious, easy to prepare, tasy, and superior to arthropods
Term
What did R. Kok suggest in 1983 concerning entomophagy?
Definition
Suggested that insects could board spaceships to provide protein to space travelers
