Past and present national tick control programs. Why they succeed or fail.
The historical reasons for the introduction of tick control during the nineteenth century are reviewed. Background and concepts for the choice between long-term tick control and tick eradication are compared. Case studies of large-scale tick control or eradication programs in Africa, Australia, the United States, and the Caribbean are used to highlight successes and failures. The main reasons for lack of sustainability, or failure, of programs are discussed. These include the economic constraints that were faced in several African countries, or technical shortcomings such as were perceived as a major problem in Puerto Rico. The successes are generally associated with enforcement of appropriate legislation and good management, such as occurred in Zimbabwe. These case studies are analyzed to identify features that may assist in the implementation of the ongoing tropical bont tick eradication program in the Caribbean. The paper concludes with some practical suggestions for the future, and the need to reassess the economics of control and the potential additional animal health benefits derived from tick control programs.
