Successes and Failures in the Tropical Bont Tick Eradication Campaigns in the French Antilles

The Amblyomma variegatum eradication campaigns, based on three phases and a 5-year program, as in other islands of the Caribbean, started in the French Antilles in April 1994 with various financial inputs. The progress of the campaigns in the two islands of Guadeloupe and Martinique contrast sharply. Owing to a shortage and inadequacy of results with regard to the initial objectives, particularly in organization, communication efforts, cattle identification, and application of acaricides on livestock, the European Community which was the most important donor, did not support the Guadeloupean program in 1996 and 1997. This induced a deep crisis in the local sanitary organization, which has the responsibility for the execution of the project, and the almost total interruption of acaricide treatments in Guadeloupe and its dependencies (Marie-Galante, St Martin, Désirade). In Martinique on the contrary, a well-defined organization, communication strategy, and personnel training effort resulted in a generalized census of livestock owners. Identification of cattle increased dramatically in number and the systematic treatment of livestock started in satisfying conditions. It is too early to anticipate on the final result of the campaign, but it is clear that a longer period of time than previously planned, will be necessary to achieve the program. If this prolongation is accepted, it may allow Guadeloupe to take part again in the campaign, a condition absolutely necessary for its regional success.
