海岛纤恙螨是在我国浙江东矶列岛(北纬28°,东经121°)发现的纤恙螨属一新种.为了确定其媒介作用,以其子代幼虫14只在作者身上作叮咬试验,证明该螨具有较强的叮人传病能力,可认定为恙虫病的传染媒介.本试验的全过程拍摄了电视录相,观察到海岛纤恙螨幼虫接触受试者皮肤后立即快速爬行,其最快速度为10cm/min,经过34～52min的爬行徘徊,然后开始叮咬.在同等试验条件下,以不同强度的光线照射受试部位,分组观察恙螨叮咬情况,证明强光直射对于恙螨叮咬人有一定影响.
Island chigger mites is a new species of chigger mites found in China’s East Island, Zhejiang Province (latitude 28 °, longitude 121 °). In order to determine its medium effect, 14 offspring of its offspring larvae were bites on the authors, The mites have strong ability to bite people, which can be identified as a vector for scrub typhus .This experiment took the video recording of the whole process, observed the island chigger mite larvae immediately after contact with the subject’s skin quickly crawling, The fastest speed of 10cm / min, after 34 ~ 52min crawling wandering, and then began to bite.Under the same test conditions, with different intensities of light exposure to the test site, the group observed chigger bites, proof of direct sunlight for ailments Mite bites have a certain impact.
