Calliphorids : Life cycle
The mature female lays their eggs on wound or
dead animals.
Hatching occurs in favourable environmental
condition,larva come out.
After two moulting larva transformed to maggots.
Then they fall on the ground,where pupation
occurs.
Development occurs then after 3-7 days adult fly
emerges out.

Calliphorids : Pathogenesis
The flies are mainly responsible for causation of
‘Myiasis’.
After hatching larva come out, then the larva crawl on
the hairs or wool and secrete proteolytic enzyme,
which digest and liquefy the tissue.
Decomposed tissue attract the secondary flies.
Due to irritation and distress their is rapid loss of body
weight
Sometime in severe case death occurs due to
septicaemia .

Calliphorids : Control
Isolation or separation of affacted sheep from
the flock.
Removal of larva from the wound.
Application of dieldrin or other chlorinated
hydrocarbon insecticides on the wound.
Dressing of the lesion .
