The aim of this study was to verify the fidelity to the diurnal roosts by the genders of the vampire bat Desmodus rotundus, and to analyse the Warfarin gel 2% effectiveness for reduction of the size of vampire bat colonies, when individuals of different sexes were treated. In 1999 and 2000, 626 vampire bats were mist netted while leaving at night 12 diurnal roosts in the state of São Paulo. They were marked, and 10% of the roost population received the Warfarin gel 2% treatment. In Test I only males were treated, in Test II only females were treated, and in Test III 5% of males and females were treated. After 5 and 10 days, the dead and the survivors were counted. Females were more loyal to the roosts (p<0,01) and better wide spreader of the Warfarin gel (p<0,01). |
