Abstract
A total of 4,575 ticks were collected from 5,953 small mammals captured from March 2004 to December 2008 at 19 military training areas and 6 US military installations, Gyeonggi and Gangwon Provinces, Republic of Korea. Ixodes nipponensis (98.9%; 753 nymphs, 3,771 larvae) was the most frequently collected tick, found on six of the 11 small mammal species captured, followed by Ixodes pomerantzevi (1.1%; 17 females, 9 nymphs 24 larvae) found on two species. While only one T. sibiricus was collected, it was infested with 44 ticks, with an infestation rate of 100.0%, followed by Rattus norvegicus (16.7%, n=18), Apodemus agrarius (14.6% n=5,397), Crocidura lasiura (7.5%, n=265), Microtus fortis (7.3%, n=82), Myodes regulus (5.7%, n=53), and Micromys minutus (4.8%, n=63). No ticks were collected from Apodemus peninsulae (n=3), Mus musculus (n=58), Tscherskia triton (n=12), and Mogera wogura (n=1). Ixodes nipponensis nymphs were most frequently collected from small mammals from March to April, while larvae were more frequently collected during September. Ixodes pomerantzevi was collected only during February-April 2008, and a single Haemaphysalis flava nymph was collected from A. agrarius in August 2004.
