*Also known as sheep ked
*Found worldwide
*Bites sheep and goats
**A separate species is found on deer
'''Recognition'''
*4-6mm long
*Hairy
*Forward pointing proboscis
*Short head
*Reddish brown colouring
*Dorso-ventrally flattened
*'Tick-like' in appearance
*'''Wingless'''
*Strong legs and claws
'''Life cycle'''
*Whole life cycle spent '''on''' the host
**Adults may survive for 1 week off the host
*Single larvae laid on fleece which pupate
*Adult keds emerge a '''few weeks to a few months''' after pupating depending on environmental temperature
'''Pathogenesis'''
*Most numerous in '''autumn and winter'''
*Located in the superficial layers of the fleece
**This aids transmission
*Long wooled breeds are most susceptible to infection
*Cause anaemia
*Wool damage
**Irritation and self-inflicted damage
**Staining by ked faeces
*Intermediate host for non-pathogenic ''Trypanosoma melophagium'' in sheep
'''Control'''
*Sheep dipping and spraying
*Shearing to decrease numbers
