Haematobia irritans-Common Name
Horn fly
26

Adult: 4mm, smallest blood sucking muscids, distinguished from stable fly bc 1/2 size and shorter proboscis Egg: 1-1.5mm
28
Haematobia irritans-Life Cycle
ELPA. Eggs laid in feces→ hatch into larvae→ pupate→ adult adults remain on hosts Dependent on temp.
29
Haematobia irritans-Site of Infection
Back, sides and abdomen | Cluster around horns when not feeding
30
Haematobia irritans-Pathogenesis and Lesions/Clinical Signs
Feed in thousands, intense irritation, impair milk production and weight gains, transmit cattle helminths, more than 200 flies leads to economic losses
31
Haematobia irritans-Diagnosis
Id fly
32
Haematobia irritans-Treatment and Prevention
Apply parasitides to host since fly remains on host most of the time Some insecticide resistance
33
Cochliomyia hominivorax-Common Name
New World Screwworm
34
Cochliomyia hominivorax-Hosts
Livestock
35
Cochliomyia hominivorax-Identification
Adults: 10mm, metallic-blueish green flies, stripes on thorax, orange brown eyes L3 darkly pigmented tracheal trunks
36
Cochliomyia hominivorax-Life Cycle
ELPA. Eggs laid on fresh, uninfected wounds of host→ eggs hatch into larvae and feed on tissues→ larvae fall to ground and pupate→ adult
37
Cochliomyia hominivorax-Site of Infection
Eggs laid on body opening or edges of fresh, uninfected wounds
38
Cochliomyia hominivorax-Pathogenesis and Lesions/Clinical Signs
Wounds attract female flies Causes "blowfly strike" Foul smelling lesion Rapidly leads to death of host
39
Cochliomyia hominivorax-Diagnosis
Recognition of maggots in lesions Must report to vet authorities immediately Place diptera larvae in alchohol
40
Cochliomyia hominivorax-Treatment and Prevention
Treat wounds | Releasing sterilized males eradicated screwworm myiasis from USA, Mexico, Caribbean and Central America
41
Hypoderma bovis/lineatum-Common Name
Warble fly, heel fly or ox warble | Larvae: Northern Cattle grub (H. bovis) Common Cattle grub (H. lineatum)
42
Hypoderma bovis/lineatum-Hosts
Cattle | *Zoonosis
43
Hypoderma bovis/lineatum-Identification
Adults: resemble bees, but 1 pair of wings, yellow-orange hairs on abdomen with broad band of black hairs around middle, no functional mouthparts L3: barrel shaped, 2.5-3 cm, dirty white and turn dark brown Eggs: H. bovis-laid singly, H. lineatum-laid in rows of 6 or more
44
Hypoderma bovis/lineatum-Life Cycle
``` ELPA Egg(s) laid on hairs of legs of cattle→ hatch→ burrow into skin and migrate through tissues→ larvae of H. bovis accumulate in epidural fat of spinal cord, H. lineatum accumulate in submucosa of esophagus→ migrate to subcutaneous tissues of the back→ fall to ground and pupate→ adult ```
45
Hypoderma bovis/lineatum-Site of Infection
Third instars, or "cattle grubs", found in lumps, or "warbles", on the backs of cattle in spring
46
Hypoderma bovis/lineatum-Pathogenesis and Lesions
L3 under skin cause damage and downgrade carcass→economic loss H. bovis: toxins from dead larvae leading to paraplegia H. lineatum: death of larvae in esophageal wall leading to bloat
47
Hypoderma bovis/lineatum-Clinical Signs
Faulty regurgitation, bloat | Paraplegia
48
Hypoderma bovis/lineatum-Diagnosis
Id fly or larvae
49
Hypoderma bovis/lineatum-Treatment and Prevention
MCLs kill early stages, timing of treatment critical

62
Linognathus vituli-Site of Infection
Head, neck, dewlap | Gregarious and form dense isolated clusters
63
Linognathus vituli-Pathogenesis and Lesions/Clinical Signs
