'''Recongition'''
+
'''Recongition of Adults'''
 +
*Medium sized flies under 10mm long
 +
 
 +
*Metallic sheen to abdomen
 +
**Colour depends on species
 +
 
 +
*Clear wings
 +
 
 +
'''Recognition of Larvae'''
 +
*Smooth maggots
 +
 
 +
*10-15mm long
 +
 
 +
*Spiracles and stigmatic plates on the tail can be used for species differentiation
    
'''Life Cycle'''
 
'''Life Cycle'''
 +
*Eggs laid in wounds, soiled fleece and on carrion
 +
**Females attracted by the odour emitted
 +
**Clusters of yellow/cream eggs laid
 +
 +
*Larvae hatch 24 hours later and crawl down onto the skin
 +
**Feed rapidly
 +
**Grow rapidly
 +
**Moult twice before becoming full maggots
 +
**Process takes 1-2 weeks
 +
 +
*Larvae falls to the fround to pupate
 +
 +
*Adult emerges in under a week (during summer)
 +
 +
*The female reaches sexual maturity after a protein meal
 +
**Lays eggs in batches of 100-200
 +
 +
*Adult flies survive for one month
 +
 +
*Between May and September four generations can develop
 +
**In warmer climates, up to 9 or 10 generations can develop per year
 +
 +
*Flies can survive the winter as pupae and emerge the next spring
 +
 +
'''Epidemiology'''
    
'''Pathogenesis'''
 
'''Pathogenesis'''
 +
*Severe skin damage
 +
**Larvae lacerate skin with oral hooks and liquefy host tissue by secreting proteloytic enzymes
 +
 +
*Skin lesions are extended and deepened
 +
**Secondary blowfly attack
 +
**Flies attracted to odour of decomposing tissue
 +
 +
*Secondary bacterial infection
 +
 +
*Production losses
 +
**Irritation and distress associated with skin lesions
 +
**Poor weight gain (often the first clinical sign)
 +
 +
'''Clinical Signs'''
 +
*Anorexia, listness, animals standing apart from flock
 +
 +
*Fleece may appear darker, be damp and have a foul smell
 +
 +
*Strike is classified according to where the body is affected
    
'''Control'''
 
'''Control'''
 +
*Prophylactic [[Ectoparasiticide|insecticide]] treatment
 +
**Must kill larvae and remain in fleece to prevent flies from laying eggs
 +
**Spraying, dipping, spray race or jetting
 +
 +
*Insect growth regulators
 +
**Pour-on
 +
**2-4 month protection depending upon the product used
 +
 +
*Effective worm control
 +
**To minimise diarrhoea and therefore soiled fleece
 +
 +
*Crutching
 +
 +
*'Mule's operation'
 +
**Surgical removal of breech skin in Merino breeds
 +
 +
*Tail docking of lambs
 +
 +
*Proper carcass disposal
 +
**Eliminates fly breeding sites
 +
 +
*Vaccination
