本文针对尖音库蚊复合组，选择了４个分类性状，包括雄蚊阳茎ＤＶ／Ｄ的比值、四龄幼虫呼吸管指数、四龄幼虫呼吸管１－Ｓ第１对毛的分枝数和第２对毛的分枝数，应用最小距离法对我国２２个地理株及尖音库蚊、淡色库蚊和致倦库蚊的实验室杂交后代分别进行聚类分析，发现尖音库蚊乌鲁木齐株和骚扰库蚊北京株与其它株距离最远，在剩余的２０株蚊虫中，除思茅株外，聚为三类，分别代表分布在我国的淡色库蚊、致倦库蚊、以及淡色库蚊和致倦库蚊的中间型。在杂交后代的聚类中发现，尖音库蚊和致倦库蚊的杂交后代与淡色库蚊没有聚在一类。
In this paper, four classification traits were selected for the Culex pipiens complex group, including DV / D ratio of male mosquito, respiratory index of fourth instar larvae, branch number of the first pair of 1-S respiratory tube of fourth instar larvae And the second branch of the number of branches of hair, the minimum distance method of 22 geographic strains and laboratory Culex pipiens pallens, Culex pipiens pallens and Culex pipiens pallens laboratory hybridization offspring were clustered analysis found Culex. Urumqi strains and Culex pipiens quinquefasciatus Beijing strain the farthest from other strains, among the remaining 20 mosquitoes, except Simao, clustered into three categories, representing Culex pipiens pallens, Culex pipiens quinquefasciatus, and pale color Culex mosquito and Culex pipiens quinquefasciatus intermediate. It was found in the cluster of hybrid progeny that the cross between offspring of Culex pipiens and Culex pipiens pallens did not belong to the same family.
