Australian sheep blowfly

Definition

A blow fly (family Calliphoridae) native to Australia and now widespread in sheep-rearing regions worldwide; the primary agent of ovine myiasis ('fly strike'), in which females oviposit on soiled wool or wounds and larvae necrotize host tissue. A major economic pest of wool sheep and target of integrated pest management programs including mulesing, chemical prophylaxis, and biological control.

Etymology

Common name reflects Australian origin and primary host association; formerly placed in genus Phaenicia.

Example

In New Zealand pastoral systems, Australian sheep blowfly populations surge in warm humid conditions, prompting farmers to apply insecticidal backline treatments before predicted fly waves.

Synonyms

• Lucilia cuprina
• Phaenicia cuprina

Related Terms

• myiasis
• calliphorid
• blow fly
• Lucilia sericata
• screwworm fly
• Integrated Pest Management
• mulesing

Usage Notes

Often contrasted with Lucilia sericata (green bottle fly), which causes similar myiasis in cooler climates; the two species overlap in range and require molecular or subtle morphological distinction. The common name is regionally used even where the species is introduced (e.g., South Africa, UK). In laboratory contexts, 'L. cuprina' predominates.
