Seasonal occurrence of larval trombiculid mites was surveyed at two adjacent areas using Tullgren s funnel method for three years. Larval trombiculid mites were collected every month from April 2004 to March 2007 at two adjacent areas of Aira City, Kagoshima Prefecture. Twenty trombiculid species were collected from soil samples: Neotrombicula mitamurai, Eltonella ichikawai, Miyatrombicula kochiensis, Cheladonta ikaoensis, Doloisia uchikawai, Helenicula miyagawai, Mackiena todai, Neoschoengastia shiraii, Schoutedenichia nagasakiensis, Walchia koshikiensis, W. ogatai and Gahrliepia saduski.Almost all species were collected in February and March, and only seven species were collected in June and July. L. scutellare was the most abundant in number, followed by L. fuji. erefore, L. scutellare and L. fuji seemed to be the dominant species in the survey areas. e morphological variation of C. ikaoensis was also observed. e scutum of C. ikaoensis was very wide, especially PW much wider than AW, and variable in the number of rst post humeral row of dorsal setae.

“…However, our results showed that many L. scutellare were collected above 20 cm, which may increase the opportunity to attach mid-sized mammals. Although we did not collect free-living W. masoni on vegetation, this species is suspected to cluster, based on sampling by Tullgren's funnel method (Uchikawa and Kumada 1978).…”

“…Though scrub typhus is an endemic disease in Asia, the Pacific and the northeast coast of Australia, larvae of trombiculid mites are important vectors of the pathogenic rickettsia, Orientia tsutsugamushi (Traub andWisseman 1974, Goddard 2000). Larval trombiculid mites are usually collected from the soil by Tullgren's funnel method (Suzuki 1973, Uchikawa and Kumada 1978, Uchikawa et al 1986) and/or from captured small mammals (Tamiya 1962, Nadchatram 1970. However, some species are collected from mid-and large-sized mammals (Kellogg et al 1971, Pung et al 1994, Forrester et al 1996.…”

We collected larval trombiculid mites on vegetation monthly from October to February 2000, and from the heads of sika deer culled in March 2003 in Boso Peninsula, central Japan. Two species of trombiculid mites, Neotrombicula nogamii Takahashi, Takano, Misumi and Kikuchi and Leptotrombidium scutellare Nagayo, Miyagawa, Mitamura and Tamiya occurred on vegetation. Peak numbers of N. nogamii were found in January and L. scutellare numbers peaked in November. Both species were collected predominantly on the top of Sasa bamboo stems, where they formed clusters, though N. nogamii preferred heights of 40-50 cm. Furthermore, N. nogamii and Walchia masoni (Asanuma and Saito) were collected from deer. These findings indicate that vegetation is an important substrate for some trombiculid mites awaiting hosts.
