A survey of acaricide resistance was performed on ticks collected from
18 dairy farms and 6 veterinary clinics in western Ethiopia. Boophilu
s decoloratus collected from most of the dairy farms were resistant to
toxaphene, but no resistance was detected in ticks collected from ind
igenous cattle. There is a need in Ethiopia to replace toxaphene on da
iry farms and formulate a rational tick control policy for the whole c
ountry.
