Seasonal abundance and species composition of trombiculid mites collected from field mice in a study of reemergence of scrub typhus associated with Leptotrombidium akamushi mites and Karp-like Orientia tsutsugamushi genotype bacteria, Japan, 2024–2025. A) Site A, near a tract of farmland; B) site B, near the riverbank. Graphs show mean numbers of mites per mouse and species composition for each sampling period. Mite species composition differed markedly between the sites: L. pallidum was predominant at site A in June (early summer) and November (autumn), whereas L. akamushi was predominant at site B in July (summer). Neotrombicula japonica and other mite species were also detected.
