本文用气相色谱法分析了不显库蠓（Ｃｕｌｉｃｏｉｄｅｓ ｏｂｓｏｌｅｒｕｓ）、兴安库蠓（Ｃ．ｓｉａｎｏｅｎｓｉｓ）、怒江库蠓（Ｃ．ｎｕｊｉａｎｇｅｎｓｉｓ）、灰黑库蠓（Ｃ．ｐｕｌｉｃａｒｉｓ）和刺螫库蠓（Ｃ．ｐｕｎｃｔａｔｕｓ）等５种库蠓雌虫脂肪酸的组成和含量。结果表明，５种库蠓均含有１２一１４种主要脂肪酸，并以棕榈油酸（Ｃ１６：１）、棕榈酸（Ｃ１６：０）、油酸（Ｃ１８：１）、硬脂酸（Ｃ１８：０）含量最高，共占脂肪酸总量的７０％以上、对主要脂肪酸的含量进行聚类分析，发现不显库蠓种团内任意两种库蠓间的欧氏距离小于不显库蠓种团种类与灰黑库蠓种团种类间的欧氏距离，说明脂肪酸的定性、定量分析结果对库蠓分类有一定的参考价值。
Culicoides obsolerus, C. sianoensis, C. nuuiangensis, C. pulicaris, and C. przewalskii (C) were analyzed by gas chromatography. .punctatus) and other five kinds of library females fatty acid composition and content. The results showed that all the five species contained 12 to 14 main fatty acids, and the contents of palmitic acid (C16: 1), palmitic acid (C16: 0), oleic acid (C18: ), Accounting for more than 70% of the total fatty acids. Cluster analysis of major fatty acids showed that the Euclidean distance between any two species in the non-dominant species was less than that in the non-species The Euclidean distance between the species and the gray-black species, indicating the qualitative analysis of fatty acids, quantitative analysis of the taxonomy of the library has a certain reference value.
