Ticks (Acari: Ixodida: Ixodidae) collected from nest soil and litter of Synthliboramphus antiquus on Chilbal Island, Jeollanam Province, Republic of Korea, with the first Korean record of Ixodes uriae White

Abstract The 65th Medical Brigade and Medical Department Activity-Korea, in collaboration with the Migratory Birds Research Center, National Park Research Institute, conducted a migratory bird tick-borne disease surveillance program on Chilbal Island during 2016. Chilbal Island is a small, remote, uninhabited government-protected island in southwestern Jeollanam Province, Republic of Korea (ROK). Ticks were collected from nest soil and litter of the Ancient Murrelet, Synthliboramphus antiquus, using Tullgren funnels. A total of 4 Ixodes ticks (3 male Ixodes uriae and 1 female Ixodes signatus) were collected. The principal hosts of I. uriae are pelagic birds that have a largely circumpolar distribution. Ixodes signatus parasitizes other migratory birds in coastal areas of western North America and eastern Asia. This is the first report of I. uriaefrom the ROK.
