我国伊蚊属已知亚属的系统发育数值分析

NUMERICAL PHYLOGENETIC ANALYSIS OF FOURTEEN SUBGENERA OF GENUS AEDES FROM CHINA(DIPTERA:CULICIDAE)

本文以我国已知的伊蚊属１４个亚属形态材料为基础，进行系统发育数值分析，构建初级树和魏格纳树。此外，并以数值聚类分析图作比较，结果显示Ｆａｒｒｉｓ－Ｗａｇｎｅｒ法较优。魏格纳树状图中１４亚属形成２群。第１群分６支派，包含Ｅｄｗ／Ｓｉｎ／Ｓｔｇ／Ｎｅｏ／Ａｅｄ／Ａｄｍ等６亚属，其中Ｓｉｎ和Ｓｔｇ亚属具有较高进化趋势。第２群分５支派，包括Ｍｕｃ／Ｆｉｎ，ｃｈｒ／Ｏｃｈ／Ｃａｎ，Ａｙｕ，Ｖｅｒ／Ｂｏｔ等８亚属，其中Ｂｏｔ，Ｍｕｃ，ｆｉｎ亚属为进化发展较高级的类群。雄蚊小抱器的出现为伊蚊属种群分化发展的重要标志。

The present paper reports a numerical phylogenetic study of 14 known subgenera of the genus Aedes from China. According to the procedures described by Farris (1970) and Simon et al. (1982) to building Primal tree and Wagner tree. And besides, the same data were analysed by numerical cluster method for comparison. The results show that the divergence dendrogram by Farris-Wagner method is better than by the numerical cluster analysis method.The Wagner tree of 14 subgenera contains 2 groups, The first group has 6 branches, containing 6 subgenera: Edw/Sin/Stg/Neo/Aed/Adm, and among the Sin and Stg with more evolutionary trends. The second group has 5 branches, containing 8 subgenera: Muc/Fin,Chr/Och/Can, Ayu,Ver/Bot, and the subgenera Bot, Muc, Fin would be the higher evolutional species groups. The results also show that the presence of claspette of male mosquitoes is the main marker for differentiate the evolutionary degree of Aedes mosquito species groups.
