	abstract = {The proportion of wool bale brands with a positive test for sheep lice in baled wool decreased from 29.5\% in 1987/88 to 23.2\% in 1990/91 before increasing to 38.2\% in 1992/93. Changes in the proportion of wool bale brands with a positive test for lice were highly correlated with changes in the Wool Market Price Indicator. The increase in the proportion of positive lice tests since 1990/91 was associated with an increase in failures to eradicate lice from flocks. These failures were partly a consequence of the reduced use of lousicidal treatments, the development of resistance to synthetic pyrethroid chemicals and an increase in the transmission of lice between flocks.},
