Abstract
Ticks that have been removed from foreign cattle, horses, numerous kinds of zoo animals, animal products and miscellaneous items presented at ports of entry and in some cases within the United States represent 9 genera and 37 species: Amblyomma americanum, A. cajennense, A. dissimile, A. gemma, A. hebraeum, A. longirostre, A. maculatum, A. ovale, A. pomposum, A. rotundatum, A. testudinis, A. tholloni, A. variegatum, Boophilus annulatus, B. decoloratus, B. microplus. Dermacentor nigrolineatus, D. nitens, D. parumapertus, D. reticulatus, Haemaphysalis leachii muhsami, Hyalomma albiparmatum, H. anatolicum anatolicum, H. dromedarii H. marginatum. H. rufipes, H. .truncation, Ixodes hexagonus, I. ricinus, I. scapularis, Ornithodoros amblus, Otobius megnini, Rhipicephalus bursa, R. evertsi, R. pulchellus, R. simus simus, and R. sanguineus. This study revealed 3 important points. Most of the exotic ticks found on imports are males; females apparently drop off at foreign quarantine stations and while the imports are en route. Native as well as exotic ticks on imported animals may be vectors of exotic disease. Harmful ticks occur on strange items and abnormal hosts.
