ABSTRACT
Vampire bats are responsible for the transmission of herbivorous rabies, a zoonosis of the greatest importance to public health. In the present study the habitats of these bats were investigated in the County of Araguari, MG, Brazil, in the period between 1996 and 2003. The objective of the investigation was to locate and register the natural and artificial shelters with hematophagous bats, estimating the median population of the colonies and the identification of the species found therein, having in mind their population control. A total of 54 shelters of Desmodus rotundus, the most frequently found hematophagous bat in Brazil were registered and grouped in 12 different kinds. In terms of their location, 81.5% of these shelters were in man-made objects, listed in regard to the decreasing order of their frequency: houses, drains, small bridges, bridges, etc., while 18.5% were in natural sites, of which caves and hollows in trees were the most frequent. Of the shelters inhabited by D. rotundus, 82.4% had an estimated population between 1 to 50 individuals, while 17.6% had between 51 and 300 individuals, with a median population of 30.2 per shelter. After treatment with Warfarin, 72.5% of the shelters were unoccupied. For effective control of rabies in herbivores it is necessary to maintain a routine registry of shelters with monitoring at least once a year.
