Mosquito-borne diseases and control

A bstract : This study was conducted in October 1998 and November 1999 in the Emas National Park (131,868 ha), a savanna‐type cerrado region situated in the far south of Goias State, Brazil, near the geographic center of South America (15°‐23° S; 45°‐55° W). Animals were captured with the aid of nets and anesthetized (15 mg/kg ketamine + 1 mg/kg xylasine) in order to collect ticks for identification and to establish laboratory colonies. They included giant anteaters ( Myrmecophaga tridactyla ) ( n = 4 ) and yellow armadillos ( Euphractus sexcinctus ) ( n = 6 ). Free‐living ticks (larvae, nymphs, and adults) were collected from the field by using a 1 × 2‐m flannel cloth. Free‐living ticks were identified as Amblyomma sp., A. cajennense , and A. triste . Adult ticks collected from anteaters were identified as Amblyomma cajennense and A. nodosum and from armadillos as A. pseudoconcolor and A. nodosum . The relevance of these host‐tick relationships to possible mechanisms underlying emergence of tick‐borne pathogens of importance to public health is discussed.
