title: Sites of attachment in Amblyomma triguttatum triguttatum Koch (Acari: Ixodidae) on natural hosts.
abstract: The sites of attachment of Amblyomma triguttatum truguttatum were studied from June to September 1981 on 146 feral pigs (Sus scrofa) and from March to August 1982 and January 1983 on 68 grey kangaroos (Macropus giganteus), naturally infested. Two hundred fifty hour (81%) of 314 nymphs were detected on the ears of the pigs; neither adults nor larvae of A. t. triguttatum were found on S. scrofa. Six hundred ninety four (97%) of 715 larvae; 283 (96%) of 295 nymphs and 11 (79%) of 14 adults of A. t. triguttatum were found on the ears of the kangaroos. The proportion of the larvae and nymphs on the ears of kangaroos and pigs respectively, decreased with the increase of tick load.
