  • Title: [Spreading of the tick Amblyomma variegatum in the West Indies: how can this serious menace be explained and what should be done?].
    Author: Uilenberg G.
    Journal: Rev Elev Med Vet Pays Trop; 1990; 43(3):297-9. PubMed ID: 2103050.
    Abstract:
    The author presents a brief history of the introduction and extension of the African tick Amblyomma variegatum in the Caribbean. The tick is particularly dangerous for the livestock industry because of its role as a vector of heartwater and its association with severe dermatophilosis. It is already distributed in the Lesser Antilles from Puerto Rico to Barbados and St. Vincent. The chronology of its sudden unexplained expansion since the 1960s corresponds well with the multiplication of the cattle egret (Bubulcus ibis) in the region, while the tick had hardly extended its distribution during more than 130 years, before this African bird arrived in the western hemisphere. These birds are often infested with larvae of the tick and carry out important movements between islands. The imminent invasion of the American continent appears unavoidable, with incalculable disastrous consequences for the livestock industry, unless the tick is rapidly eradicated from all infested islands. While presenting practical, human and social problems, eradication from the islands is technically feasible and its cost/benefit ratio is very positive.
