The occurrence of larval trombiculid mites in different vegetation types was surveyed in Kagoshima and Nagasaki Prefectures. In Kagoshima Prefecture, 10 species were collected at three sites. Leptotrombidium scutellare was dominant, followed by L. pallidum and L. fuji. L. scutellare and L. pallidum were collected in three vegetation types. The biggest numbers of both species were recorded at the natural woods of two sites and at the grassland of one site. In Nagasaki Prefecture, four species were collected at three sites, and L. scutellare was also dominant. L. scutellare was collected in two vegetation types. The greater number of L. scutellare was recorded at the grassland of two sites and at the natural woods of one site. The distribution of L. scutellare larvae was also surveyed along roads passing through hilly and mountainous areas of both prefectures. In Kagoshima Prefecture, the collection of larval trombiculid mites with a black cloth (Suzuki's method) was carried out at 52 sites along five routes, and L. scutellare was found in 41 sites (78.8%). In Nagasaki Prefecture, the collection of larval trombiculid mites was carried out at 43 sites along five routes, and L. scutellare was found in 4 sites (9.3%). The wide occurrence and high density of vector mites seems to relate to the number of patients in Kagoshima Prefecture.
