Ixodid ticks were present in all 189 samples examined from 53 Florida
panthers (Felis concolor coryi, 104 collections) and 85 bobcats (Felis
rufus floridana) in Florida (USA) between 1974 and 1991. We identifie
d 3,251 ticks from panthers and 918 from bobcats. Specimens of Dermace
ntor variabilis, Ixodes scapularis, I. affinis, Amblyomma maculatum, a
nd A. americanum were present on 49, 39, 17, seven, and two of the 53
Florida panthers, respectively, and comprised 36%, 55%, 7%, 1%, and <1
% of the 3,251 ticks collected from panthers. Ixodes scapularis, D. va
riabilis, and I. affinis were present on 61, 56, and 11 of the 85 bobc
ats respectively, and comprised 58%, 39%, and 2% of the 919 ticks coll
ected. Amblyomma americanum and A. maculatum were found infrequently a
nd comprised <1% of the total ticks collected from bobcats. Only adult
ticks were found on the cats, except for one D. variabilis nymph and
three A. americanum nymphs that were found on bobcats.
