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.
The progress and problems in the Caribbean Amblyomma Program (CAP) are reviewed since its inception in 1995. During 1998, there were funding and administrative management problems. USDA resolved the acute funding crisis, and after three years of negotiation, the CAP has now secured an additional euro 1.5 million from the European Community. Changes in administration in 1998 included the withdrawal of IICA from the program, and the transition during the decentralization of administrative and financial management from FAO headquarters to the Regional Office for Latin America and the Caribbean, based in Chile. A general overview of technical progress and one case study, St. Kitts, is presented. One major concern that emerged during 2000 is that the elimination of the small remaining tropical bont tick (TBT) "hot spots" in both St. Kitts and St. Lucia remained elusive. Why is this so? Egrets? Alternative residual hosts? Or is it fatigue in both technical and administrative management functions? Of even greater concern is the finding of two, apparently new, foci in St. Croix (USVI) in the north and St. Vincent in the south. A critical overview of the program has identified one major remaining constraint-an appropriate management support function at both regional and, in some countries, at the national level. A proposal for a revised management strategy, coupled with the identification of a future strategy to succeed the CAP, namely a Caribbean Animal Resources Management (CARM) Program.
The objective of the Caribbean Amblyomma Program is to eradicate the tropical bont tick (TBT), Amblyomma variegatum, from the Caribbean. Field activities directed to eradication of the TBT were initiated in May 1995 commencing in northern Caribbean islands. Plans have been finalized for the remaining islands to the south to start eradication activities in early 1997. The components of the program include tick control and surveillance, adaptive research, training, communications, and extension. Despite uncertain financial support, substantial progress has been made so far with strong participation by farmers and livestock owners who have been made responsible for the compulsory treatment of all ruminant livestock.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
