[Trombiculid mites (Acarina: Trombiculidae) from Apodemus agrarius coreae caught at Pochun-gun, Gyeonggi Province and Chinhae-City, Kyongnam Province].
During October-December 1987, chigger mites infested on the striped field mice (Apodemus agrarius coreae) collected at Pochun-gun, Gyeonggi Province and Chinhae city, Kyongnam Province were identified. 1. Of 171 back-striped mice collected, chigger mites were found from 58 mice, showing 33.9% of infestation rate. 2. Total 865 chigger mites collected were classified into seven species; Leptotrombidium pallidum (4.3%), L. palpale(23.0%), L. orientalis(20.2), L. zetum(19.0%). Neotrombicula tamiyai(32.9), N. japonica(0.2%) and Euschongastia koreaensis(0.3%). Though the most dominant species in number was N. tamiyai(32.9% of the total), this species was collected at very limited locality and for a short period. Therefore, most common species in Korea seems to be L. palpale which was found at all localities throughout the whole survey period. L. pallidum which is known as the vector species of tsutsugamushi disease in Korea was collected in a very low number(4.3% of the total chiggers collected). 3. The number of chigger mites infested on a host animal showed great variations from one chigger up to 207 chiggers. The present study has shown that there may be other Leptotrombidium species mite(s) for the vector and host of tsutsugamushi disease in Korea.
