A

egg laid in environment- larvae hatch (6 legs)- find small mammal host- feed- fall off - become nymph (8 legs)- hop onto small mammal- feed- drop off- molt to adult (8 legs)- hop on large animal

Q

Cutaneous bot of cattle lifecycle

A

eggs glued on hair of cow- eggs hatch- larvae move through skin to SQ tissues of the back- warbles form with breathing holes- larvae molts two times- stage 3 larvae exits and falls to ground- pupate in soil- adult finds new host

17
Q

Myasis

A

maggot infection (any type of fly)

18
Q

Cuterebra life cycle

A

eggs laid near rabbit burrow- host moves by- hatch and larvae grabs on- migration- burrow SQ with breathing hole- larvae molt- larva emerge- burrows in soil and pupates- overwinters- adult fly emerges

19
Q

Screw worm life cycle

A

Adults lay eggs on wounds- eggs hatch- maggots feed on living flesh- mature larvae leave host and pupate in soil- adults emerge from pupae

20
Q

Ked life cycle

A

winged adult ked flies to a sheep- adult loses its wings when it lands- adults mate- adult female nourishes maggots within her uterus- maggots are born- maggots become pupae- pupae remain glued to sheep- mature to release an adult ked

21
Q

Sheep nasal botfly life cycle

A

deposit clutch onto nares of sheep- l1 larvae migrate into nasal passage- 2 further instars- l3 larvae migrate back, sneezed out- burrow into ground before pupating

22
Q

Stomach bot in horse lifecycle

A

eggs on hairs around lips- eggs hatch and larvae burrow- 2nd stage larvae migrate to stomach- mature larvae passed in feces- pupate in soil- release adults

23
