Fleas (Siphonaptera) From the Puma, Puma concolor (Carnivora: Felidae), A Rangewide Review and New Records from Utah and Texas, USA

Abstract

Abstract Fleas have rarely been reported from the puma, Puma concolor (Linnaeus, 1771), despite its vast geographic range, its breadth of habitat use, and its diverse diet, all of which bring it into contact with many other species of mammals and potentially their fleas. We review the reported occurrence of 8 species of fleas from pumas, 7 of these species being from wild hosts and 1 species from a host in captivity, and we correct the mistaken report of 1 other flea species from the puma. We present 10 new records of 4 species of fleas from the puma in Utah and Texas. 2 of these flea species, Cediopsylla inaequalis inaequalis (Baker, 1895) and Odontopsyllus dentatus (Baker, 1904), represent new host records, and 1 species, Chaetopsylla setosa Rothschild, 1906, is a new state record for Utah as well as being 1 of the 2 southernmost known localities for this species. At least 7 of the 9 flea species now known from free-ranging pumas are species that are acquired by pumas from their prey. Pumas may be primary hosts of 2 flea species, but even these fleas may be from prey. Some of the flea species that parasitize pumas transmit sylvatic plague, and, since pumas are highly vagile and are known to become infected with plague, they may spread the disease through their dispersal of infected fleas. Pumas and their fleas also may be involved in the ecology of several other bacterial zoonoses, which are discussed.
