2006年10月至11月在大韩民国13个地点进行了一项调查，以确定恙虫病潜在病媒的地理分布和相对丰度。黑线姬鼠80只，占总数的97.6%，正常鼠2只。共采集恙螨10，860只。agrarius 4属8种，而Myodes regulus中仅采集到脆弱Walchia fragilis 40种。苍白纤恙螨（8，137; 74.9%）是恙虫病的主要媒介，是从A.其次是小盾纤恙螨（2，057; 18.9%）、须纤恙螨（279; 2.7%）、东方纤恙螨（232; 2.1%）和斑马纤恙螨（79; 0.7%）、田谷新恙螨（58; 0.5%）、朝鲜真恙螨（16; 0.1%）和伊考螯齿螨（2; < 0.1%）。L.在江原道（100%）、京畿道（87.2%）、忠南（100%）、忠北（100%）、全北（73.9%）、全南（77.0%）和庆北（66.1%）等省份的采集点采集的恙螨中，苍白恙螨是主要的恙螨，而L.在庆尚南道（77.9%）和济州岛（62.3%）采集到的恙螨中，以小盾恙螨为主。数据表明，韩国恙螨种群丰度与人类恙虫病病例之间存在相关性。
A survey to determine the geographical distribution and relative abundance of potential vectors of scrub typhus was conducted from October to November 2006 at 13 localities throughout the Republic of Korea. Apodemus agrarius accounted for 97.6% (80/82) of all rodents, while only 2 Myodes regulus (2/82) were collected. A total of 10,860 chiggers were collected from A. agrarius belonging to 4 genera and 8 species, while only Walchia fragilis (40) was collected from Myodes regulus. Leptotrombidium pallidum (8,137; 74.9%), a vector of scrub typhus, was the predominant species collected from A. agrarius followed by Leptotrombidium scutellare (2,057, 18.9%), Leptotrombidium palpale (279; 2.7%), Leptotrombidium orientale (232; 2.1%), and Leptotrombidium zetum (79; 0.7%), Neotrombicula tamiyai (58; 0.5%), Euschoengastica koreaensis (16; 0.1%), and Cheladonta ikaoensis (2; < 0.1%). L. pallidum was the predominant chigger collected at collection sites in Gangwon (100%), Gyeonggi (87.2%), Chungnam (100%), Chungbuk (100%), Jeonbuk (73.9%), Jeonnam (77.0%), and Gyeongbuk (66.1%) provinces, whereas L. scutellare was the predominant chigger collected in Gyeongnam province (77.9%) and Jeju Island (62.3%). Data suggest a correlation between chigger population abundance and human cases of scrub typhus in Korea.
