50年代初期,作者在浙江东矶列岛发现一新种恙螨,定名为海岛纤恙螨,经生态学、病原学、流行病学研究,证实该螨各变态期(卵、幼虫、若虫、成虫)内均保有恙虫病立克次体;并能经卵传递恙虫病立克次体;能够叮人传病;具有自然感染;为当地恙虫病疫源地绝对优势种,其季节消长、生境分布均与恙虫病的流行相吻合。对照国际公认的确定媒介恙螨的标准条件,该螨已完全具备。故认定:我国发现的海岛纤恙螨新种为恙虫病新媒介。
In the early 1950s, a new species of chigger mite was found on the East Side Island in Zhejiang Province. It was named as an island chigger mite. The ecological, etiological and epidemiological studies confirmed that the mite metamorphosis (egg, larva, nymph, adult ) Were scrub typhus Rickettsia; and can be transmitted by eggs Rickettsia rickettsia; can bite people with disease; with natural infection; for the local scrub typhus absolute dominant species, the seasonal decline, habitat distribution Are consistent with the prevalence of scrub typhus. The mites are fully controlled against internationally recognized standards for the identification of chigger mites. Therefore, it is concluded that the new species of chigger mites found in our country are new vectors for scrub typhus.
