The genus Ixodes Latreille (Acari, Ixodida) includes about 231
species distributed in 14 subgenera worldwide (C Clifford et
al. 1973 An Ent Soc Am 66: 489-500). Some species can parasite
birds or mammals in their different stages, others have been
found only on mammals, mainly in their nymphal and adult
phases (H Aragao 1936 Mem Inst Oswaldo Cruz 31: 759-843, R
Cooley & G Kohls 1945 Nat Inst Hth Bull 184: 1-246). Many
Ixodes species are associated with paralyse promotion or
pathogenic agent transmission to several animals (A Kocan 1988
Jama 192: 1498-1500, J Butler & H Denmark 1990 Ent Circ
326, F-F Matuschka & A Spielman 1992 Ex Parasitol 74:
151-158).
In Brazil, nine species of Ixodes are known: I. amarali
Fonseca, I. aragaoi Fonseca, I. cooleyi Aragao & Fonseca,
I. coxaefurcatus Neumann, I. didelphidis Aragao & Fonseca,
I. fuscipes Koch, I. loricatus Neumann, I. luciae Sennevet,
and I. schulzei Aragao & Fonseca (H Aragao & F Fonseca
1961 Mem Inst Oswaldo Cruz 59: 115-129).
During bird banding in the municipality of Curitiba, next
to the Passauna River, in an Araucaria forest (Araucaria
angustifolia) from March to May 1992, autumn months, three
specimens of Turdus rufiventris and one specimen of T.
albicollis were captured and examined for ectoparasites. Four
ticks specimens were found. They were removed from the hosts
and were preserved in Oudeman's fluid, according to G Krantz
(1978 2nd ed. Oregon State University Book Stores, Oregon, 509
pp). The ticks were identified as I. auritulus using criteria
proposed by M Mendes-Arocha and I Ortiz (1958 Mem C Nat La
Salle 51: 196-208). The specimens, two females (F) and two
nymphs (N) were deposited in the Parasitological Collection of
the Museum of Natural History "Capao da Imbuia" (MHNCI 92,
93-F; MHNCI 93, 94-N).
Although I. auritulus is common ectoparasite of birds,
including sea birds (Clifford loc. cit.), it has been also
observed on mammals. E Jones et al. (1972 B Y Un Sc Bull 17:
1-40) found larvae and nymphs on wild rodents from Venezuela.
J Botelho (personal communication) observed this species on
Dasyprocta fuliginosa (Rodentia) in Brazil.
The only record for I. auritulus in Brazil (Cooley &
Kohls loc. cit.) is restricted to birds, Knipolegus
nigerrimus, Thamnophilus ruficapillus, and T. caerulescens
from Itatiaia Mountains in the State of Rio de Janeiro. It
seems that Aragao and Fonseca (1961 loc. cit.) omitted
mentioning the occurrence of this species, although they were
aware of it (H Aragao & F Fonseca 1952 Mem Inst Oswaldo
Cruz 50: 727-728). In the State of Parana, there are only
records of I. loricatus and I. didelphidis on mammals (L
Guimaraes 1945 Arq Mus Paran 4: 179-190, S Ribeiro 1966/1967
An Fac Med Un Fed Parana 9/10: 7-47, D Barros & D Baggio
1992 Mem Inst Oswaldo Cruz 87: 291-296).
This communication records the first occurrence of I.
auritulus in Parana, and probably constitutes the first report
on T. rufiventris and T. albicollis. These two Turdus species
are not migratory but are well disseminated in Brazil and
other South American countries (R Schauensee 1982
Intercollegiate Press, Filadelfia, 498 pp, H Sick 1988 3rd ed.
I/II, Brasilia, 827 pp). Studies on biology and ecology of
Ixodes spp. parasiting birds are being carried on so that
aspects of their dispersion may be clarified.
