| Ichneumonidae/Braconidae | parasitoid wasp juveline - tobacco hornworm - emerald ashwood borer - ovipositor - venom, virus, teratocyte - polydynavirus |
| Nematocera | sand fly, mosquito, black fly |
| Brachycera | tsetse fly, stable flly, calliphoridae |
| P.h. humanus, capitis + pubis | lice - nit - no free living stage - anoplura - vector vs not vector - dorsoventrally flat - stylet - buccal teeth - pustules |
| C. lectularis | bedbug - no free living - no disease - each nymphal instar needs blood meal |
| T. penetrans | flea - adult para, juvenile not - plague, infection - bilateral flat - jumps |
| Ergasilidae | gill lice - FW - columns |
| Caligidae | sea lice - SW - free - scary ones |
| Argulus | fish lice - FW and SW - inorganic |
| Sacculina | feminization of crabs - ventral nerve - seta |
| C. exigua | deep sea pacific - M to F - eats tongue |
| Demodex | furry - hair follicle - dogs |
| S. scabiei | scabies - us vs dog - allergy - burrows - molting pouch - ivermectin - Vicuna |
| I. scapularis | hard tick - blacklegged/deer tick - white marking - lyme |
| D. variabilis | hard tick - american dog tick - brown back - paralysis |
| what is the importance of schistosoma in waste, agriculture, food prep? | consider fecal oral route, oxen as hosts, nothing to do w food prep tho |
| How do parasites impact the environment other than illness? | consider wildlife impact - snail castration - host behaviours - impacts on other trophic levels |
| why are microscopes important? | they're fast, cheap, and easy to use. reliable if searching for specific characteristics, easy to find and use, cheap to use nowadays, and very quick results good to act fast |
| what parasite(s) are not important to humans but that impact us? | Meloidogyne and pratylenchus - crops |
| how would you differentiate between anclystoma duodenale and necator americanus | teeth, DP/oral/breastmilk transmission, 10k-30k eggs, 1yr old cutting plates, DP only, 5-10k eggs, 3-5yr old |
| how would you easily identify T.trichuria? | plugged egg!? |
| how do parasitoid wasps do their thing? | venom to subdue/pacify the host, virus polydenavirus to modulate immune response, teratocytes to alter host behaviour |
| list the differences in area, eggs, and transmission between head lice, body lice, pubic lice | head: scalp on host, eggs at base of hair, head-head contact body: clothes, eggs on fibers, contact between people or items pubic: pubic area/coarse hair, eggs in coarse hair, intimate contact |
| describe the importance of sarcoptes scabiei in Vicuna | vicuna with scabiei are weaker and easier for prey to catch. prey goes up a bit, condors too, but vicuna pop decreases fast. eventually upper trophic levels suffer, and grass overgrows too. |
| what are differences between ixodidae and argasidae | hard: 3 hosts, long feed, mate on host, 1 batch eggs, questing soft: many hosts , many short feeds. mate off host, small batches. sheltered |
| what are differences between ixodidae scapularis and variabilis | scapularis: white mark, 4-6mm, grass, warm time, can carry lyme. variabilis: dark mark, 3-5mm, edge of trail/brush, cold time, tick paralysis |
| what is the bacterium causing lyme? what is the sign | Borrelia burgdorferi; bullseye rash (erythema migrans) |
| discuss where and why sterile male technique can be successful | good for quickly reducing population - especially good for carriers that mate once and lay eggs multiple times like the new world screwworm. |
