The age and-or physical condition of mulesing wounds had a significant effect on both the oviposition response of L. cuprina and the ability of the wound to support a strike. Up to 48 h after mulesing, untreated wounds elicited a strong oviposition response in contrast with chemically treated wounds, although subsequent larval development was negligible. Seven to 9-day-old wounds, however, regardless of the wound treatment, were highly attractive oviposition sites, which subsequently developed into strikes; the D3 formulation of Defiance*S, however, significantly depressed strike development and shows promise as a mules wound treatment. A marked improvement in the wound healing 14 to 16 d after mulesing coincided with a significant decrease in oviposition. Only those sheep whose scabs remained broken, exposing pus and raw tissue, attracted oviposition; subsequent development of the eggs into strikes was negligible.
