| Popis: | Information provided by wool growers in Queensland, Australia between 1995 and 1997 was used to assess the prevalence and spatial distribution of louse ( Bovicola ovis ) infestation in sheep flocks. The estimated prevalence of louse-infested flocks was 40% (95% confidence interval, 35–46%). Although the prevalence of infestation was higher in western regions (41–50%) compared to the south region of Queensland (31%), the difference was not statistically significant ( P > 0.05). Significant ( P = 0.02) clustering of infested flocks was detected in the south region where two foci were apparent. We conclude that Queensland sheep flocks have a moderate prevalence of louse infestation, and that clustering of infestation is not strong. The control of lice is an industry-wide issue that needs to be addressed by most wool growers in Queensland. |
