L5: Flies & Myiasis (MOST UTD) Flashcards
what does oviparous mean
flies lay eggs
what does ovoviparious mean
flies release larvae
what does hematophagous mean
flies feed on blood
what is myiasis
larval stage of fly feeds on host tissues
consequences of biting flies
- disrupt normal behavior
- inflammatory response to bites leads to further disruptive behaviors
- pruritis, dermatitis, scratching, biting etc
- transmit pathogens
how do non-biting flies irritate/damage the mucous membranes of their hosts
spines on their mouthpart
consquences of non-biting flies
- transmit pathogens
- myiasis can cause: tissue destruction, secondary bacterial infections and obstruction of respiratory / GI tracts
what are the 3 important genus of mosquitoes to know
- Aedes

- Culex
what are two important pathogens transmitted by mosquitoes
- Canine heartworm

Black flies
toxins build up in animals bitten by LOTS of black flies, causes them to go into shock and die
what are the 2 important species of black flies (Simuliidae)
- Leucocytozoon spp. (devastating to birds, esp poultry)

Musca autumnalis
face fly
feed on ocular/nasal discharge of livestock
Musca domestica
- housefly
- most abundant insect pest associated w/ livestock, poultry and people
- feed on ocular/nasal discharge and other bodily fluids

Culicoides spp.
biters of mammals and birds
important parasite transmitted by midges
Leucocytozoon
what fly causes equine allergic dermatitis
Midges (Culicoides spp)
2 important species of Sandflies
- Lutzomyia (new world)
- Phlebotomus (old world)
pathogen carried by Sandflies
Leishmania spp.
