in land on organic material

18

A

compound

19
Q

ocellus

A

proprioceptive organ of cyclorrapha

20
Q

how cyclorrapha larvae breath?

A

through prothoracic spiracles

21
Q

cyclorrapha larvae mouth?

A

oral hooks

22
Q

cyclorrapha egg laying can be

A

viviparous or oviparous

23
Q

lifecycle of cyclorrapha

A

egg-> larva/or larva
l1-l3
pupation in soil
adults emerge from cocoons

24
Q

specific myiasis causing flies

A

oestrus
hypoderma
gasterophilus

25
Q

semi-specific myiasis causing flies

A

calliphora

wolfarthia

26
Q

sucking cyclorrapha

A

musca

27
Q

biting cyclorrapha

A

glossina
hippobosca
melophagus

28
Q

how do sucking and piercing proboscis differ?

A

sucking proboscis is short with wide end

piercing proboscis is long and very thin

29
Q

hippobosca vs melophagus

A

hippobosca has wings and melophagus does not

30
Q

gasterophilus intestinalis

A

adults lay eggs in the horse
horse licks and swallows the eggs
saliva cause larva to eclosinate
in stomach l3 fixes itself to stomach with oral hooks
exits in spring through feces
bury themselves in the soil and evolve to pupae
adult emerges and mates

31
Q

oestrus ovis life cycle

A

females lay eggs in nostrils
larvae 1-3 penetrate into nasal sinuses
then get out form pupa in soil and become adults

32
Q

what do hypoderma do?

A

disturb cattle by flight cause dermal irritation by the larval skin penetration and migration
