A laboratory colony of Leptotrombidium (Leptotrombidium) pallidum infected with Rickettsia tsutsugamushi, the causative agent of scrub typhus, was derived from a single field-collected mite. Transovarial transmission of R. tsutsugamushi through the first generation (F_1) of this trombiculid mite was demonstrated. The filial infection rate was 100%, and all the adult males were infected with R. tsutsugamushi. This finding in R. tsutsugamushi-infected colony of L. pallidum was characterized by the high ratio of the male among F_1 progenies and 100% filial infection rate of males, which was contradictory to those in the other R. t.-infected species of chigger mites.
