Abstract

The cost of fly strike to sheep farmers is considerable. Apart from animal deaths, other costs include: labour and chemicals for control, reduced wool value and poorer animal performance. Also, there is a cost in animal suffering and potential for chemical contamination of wool. Furthermore, fly resistance to currently available forms of chemical control is increasing. A complementary approach to controlling fly strike is to enhance the animal’s genetic resistance via selection.
