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 nine 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. truncatum, 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 three important points: (1) 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. (2) Native as well as exotic ticks on imported animals may be vectors of exotic disease. (3) Harmful ticks occur on strange items and abnormal hosts. Soon after the establishment in 1884 of the old USDA Bureau of Animal Industry, parent organization of our present research division, a collection for all kinds of animal parasites was established. Ticks, like other parasites, were accessioned into the parasite collection by assigning them a number with information on the host, locality, collector's name and date, and the name of the individual determining the species. Ticks collected from zoo, wild, and domestic animals within the United States and from animals, animal products, and miscellaneous items presented for entry into the country have been received for identification and deposited in this collection, now housed for over 70 years at the Beltsville Parasitological Laboratory. The information in this report is based on the ticks in this collection that were found on animals and items that were offered for entry or recently imported into the United States. The purpose of this report is to indicate those species that have been found at ports of entry (POE) as well as where they have been found within the country. Several of the ticks named herein transmit a number and variety of diseases. The diseases they transmit have been covered by other writers (Hoogstraal, 1956; Arthur, 1961; and Philip, 1963). Received for publication 23 January 1968. * Presented at the 2nd International Congress of Acarology, University of Nottingham School of Agriculture, Sutton Bonington, Loughborough, England, 19-25 July 1967. TICKS FOUND ON IMPORTS The ticks found on animals and various items are listed in Table I with the host or item on which they were found, locality collected, and place of origin. The information relating to hosts is indicated as provided with the ticks. Comments on the hosts and their origin are included in the subsequent discussion and conclusions. Several hosts were infested with more than one species of tick and these hosts are listed accordingly under each tick. Amblyomma Amblyomma americanulm, A. cajennense, and A. maculatum are native species of the Americas. These ticks are easily distinguishable from Boophilus ticks by tick inspectors; therefore, it is highly possible they have not been routinely sent in for identification. Consequently, they may occur more commonly on animals from countries south of the United States than Table I indicates. Both A. americanum and A. maculatum are common parasites of wild and domestic animals in the southern United States; whereas, A. cajennense is only established in southern Texas. The ticks of the last named species reported in Illinois and Georgia were collected in 1915 and 1916, respectively, on horses from Guatemala. The specimens of A. gemma, A. hebraeum, A. longirostre, A. ovale, A. pomposum, A. tholloni, and A. variegatum were all males. Three
