本文报导了作者三年来对湘西五倍子蚜虫冬寄主藓类的部分研究结果，共收录冬寄主藓类30种，其中18种为湖南冬寄主藓类新记录，并在野外实在考察的基础上提出了本地生产中最为重要的5种冬寄主名称。此外，作者对部分藓种作了分类上的修订。
The authers report 30 species of the winter-host mosses of 7 gall aphides in western hunan based on about 350 specimens collected during their fieldworks. Among the above winter-host mosses. 18 species are cultured in the laboratory or in the experimental field of the Jishou University, and 18 species are newly recorded in Hunan. All of the specimens are preserved in JSHU.
Acording to the frequency of mosses, their characteristic of growth, and the effect as the winter hosts, the authers believe that the most important winter hosts in W.
