The distribution of ticks of the Ornithodoros moubata complex (Ixodoidea: Argasidae) in Malawi and its relation to African swine fever epizootiology.

摘要

The distribution of ticks of the Ornithodoros moubata complex in different habitats in Malawi, particularly pigsties and houses, was established from a four-phase survey undertaken between 1982 and 1985. The first phase consisted of preliminary interviews, the second phase consisted of a questionnaire to Veterinary Assistants (VAs) in rural areas, the third involved tick collections by VAs and the fourth involved both interviews and tick collections by members of the Central Veterinary Laboratory, Lilongwe. The area in which O. moubata is found in pigsties includes much of the African swine fever (ASF) enzootic area, and it seems likely that the enzootic area could become larger in future. The occurrence of O. moubata in warthog habitats was also investigated.
