1992年10月8日至1993年1月8日，我们用Tullgren漏斗法对日本神奈川县山市Sengenyama和Maruyama山坡上的住宅周围和柑橘橙子格罗夫斯林进行了恙螨幼虫调查。共采集恙螨幼虫6，690尾，其中小盾纤恙螨6，669尾（Nagayo，Mitamura，Tamiya & Tenjin），小盾纤恙螨13尾（L. fuji Kuwata，Berge & Philip，两个L. himizu（Sasa，Kumada，Hayashi，Enomoto，Fukuzumi & Obata），日本新恙螨Neotrobicula japonica（Tanaka，Kaiwa，Teramura & Kagaya）2只，白腹瘿螨Gahrliepia saduski Womersley 1只，小笠原Walchia ogatai Sasa & Teramura 3只，共采集40个土样，每2-4周采集6次。从上述种类组成来看，L.盾疑似是调查区丛林斑疹伤寒的唯一媒介，已知该疾病是由恙虫病绪方立克次体的两种血清型菌株（川崎和黑木）引起的。L. 10月下旬，小盾蚧幼虫数量迅速增加，11月上旬达到高峰，随后逐渐减少。
Using the Tullgren funnel method, we surveyed for trombiculid larvae around dwellings and in mandarin orange groves on the slopes of Sengenyama and Maruyama, Yamakita Town, Kanagawa Prefecture, Japan, during the period between 8 October 1992 and 8 January 1993. In total, 6,690 trombiculid larvae, consisting of 6,669 Leptotrombidium scutellare (Nagayo, Mitamura, Tamiya & Tenjin), 13 L. fuji Kuwata, Berge & Philip, two L. himizu (Sasa, Kumada, Hayashi, Enomoto, Fukuzumi & Obata), two Neotrombicula japonica (Tanaka, Kaiwa, Teramura & Kagaya), one Gahrliepia saduski Womersley, and three Walchia ogatai Sasa & Teramura, were taken from 240 soil samples (40 samples, six times at intervals of 2-4 wk). From the above species composition, L. scutellare is suspected to be the sole vector of scrub typhus in the survey area, where the disease is known to be caused by two serotypic strains of Rickettsia tsutsugamushi Ogata, Kawasaki and Kuroki. L. scutellare larvae rapidly increased in number in late October to form an acuminate peak of abundance in early November, followed by a gradual wane.
