Ticks on livestock in Barbados

Cattle, sheep, goats, and horses in most areas of Barbados were examined for ticks. About 68% of the cattle, mostly Holstein dairy cows, and 23% of the sheep, mostly purebred or crossbred black belly sheep, were infested with the southern cattle tick, Boophilus microplus (Canestrini), a vector of bovine babesiosis and anaplasmosis. About 13% of the horses were infested with the tropical horse tick, Anocentor nitens (Neumann), a vector of equine babesiosis. Cattle owners used a variety of acaricides as dusts, sprays, or washes on their cattle for the control of ticks.
