  −
*''C. bezziana'' cause myiasis in both animals and humans
  −
 
  −
*Located mainly in tropical regions
  −
 
  −
*Larvae are '''obligate''' parasites
  −
 
  −
 
  −
'''Recognition'''
  −
*Similar to ''Calliphora spp.''
  −
**Iridescent
  −
**Clear wings
  −
**Blue abdomen
  −
 
  −
*Longitudinal stripes on thorax
  −
 
  −
*Larvae have bands of spines
  −
**Look like screws
  −
 
  −
 
  −
'''Life cycle'''
  −
*Eggs laid in wounds or body cavities
  −
 
  −
*Larvae feed as colonies
  −
 
  −
*Larvae drop to the ground to pupate
  −
 
  −
 
  −
'''Pathogenesis'''
  −
 
  −
*Spiracles are exposed as larvae feed which expands the wound
  −
**Creates a foul smelling lesion
  −
 
  −
*Cause irritation and pyrexia
  −
 
  −
 
  −
'''Control'''
  −
*In the USA
  −
**Mass eradication through the release of sterile males
  −
**Currently only persists where flies have migrated across the Mexican border
  −
 
  −
*In Africa
  −
**Introduced into Libya through the importation of infested livestock
  −
**Sterile males released
  −
**Eradication occurred in 1991

  −
*Human medicine
  −
**Sterile ''Lucilia sericata'' maggots used to treat infected and necrotic wounds
  −
**Larvae secrete proteolytic enzymes and antimicrobial agents into the wound
  −
**Larvae do not burrow under the skin or attack healthy tissue
  −
 
  −
*Veterinary medicine
  −
**Published reports rare
  −
**Recently used successfully to treat a suppurative wound in a donkey that did not respond to conventional medical methods and surgery

  −
 
  −
*Black stripes on thorax
  −
 
  −
*Black spots on abdomen
  −
 
  −
 
  −
'''Life cycle'''
  −
*Larvae deposited directly onto host
  −
 
  −
*No egg stage
  −
 
  −
*Larvae moult twice on host then fall to ground to pupate
  −
 
  −
 
  −
'''Pathogenesis'''
  −
*Larvae penetrate intact skin
  −
**Cause boil like swellings
