摘要
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。
his paper deals with the fatty acids in female midges of five species. Theyare Culicoides obsoletus (Meigen), C. sinanoensis Tokunaga, C. nujiangensis Liu,C. pulicaris (Linneaus) and C. punctatus (Meigen). The results showed that therewere 12--14 major fatty acids in the female midges, of which the predominant ingredients were palmitoleic (C16: 1 ), palmitic (C16: 0). oleic (C18: 1 ), and steraic(C18: 0).Clustering analysis revealed that the Euclid distances between any two species of C.obsoletus group was closer than that between C. obtoletus group and C. pulicarisgroup. The differences of the ingredients and contents among the five species areof some reference values to the taxonomy of Culicoides midges.
