Using the principle and methods of Cladistics to systematically study the comparative and evolutionary morphology of sawfly larvae of Hymenoptera; to reconstruct the phylogeny of sawflies and to probe on the co- evolution between sawflies and their host plants; further more to collect enemies of some important sawfly pests.

应用支序系统学原理和方法，系统深入地研究膜翅目叶蜂类幼期比较和进化形态学，推断和重建叶蜂系统演化关系，探讨叶蜂类昆虫与寄主植物之间协同进化关系，初步筛选重要叶蜂害虫的天敌昆虫。

Based on morphological and biological studies, 36character transformation series of 10 species of the genu Apanteles Foerster and 2 species of the genu Dolichogenidea Viereck were recognized. Through analysis of character polarity using the method of outgroup analysis, two and multiple character data matrixe were obtained. The data is analysed through PHYLIP(Phylogeny Inference Package, version 3.6) software based on the method of cladistics, a majority rule consensus tree and a strict consensus tree constructed at last.

在本研究中，描述了10个种，做出了中国绒茧蜂属Apanteles Foerster种类雌蜂检索表，以绒茧蜂属的10个种作为内群，以长颊茧蜂属Dolichogenidea的2个种为外群，基于形态学和生物学分析建立了36个性状演系列，通过外群比较法，得到一个由二性状和多性状数据矩阵，再用phylip(系统发育推断软件3.6版)处理数据矩阵，最后得到一个多数规则合意树和一个严格合意树。

In my study, based on morphological and biological studies, 53 character transformation series of 23 species which stand for 23 genera of the Microgastrinae in China respectively and 2 species of Miracinae and Cardichilinae were selected. Through analysis of character polarity using the method of outgroup analysis, two and multiple character data matrixe were obtained. The data is analysed through PHYLIP(Phylogeny Inference Package, version 3.6) software based on the method of cladistics, the consensus cladograms was constructed at last.

本研究以分布在中国东洋区和古北区的小腹茧蜂亚科23个属的23个种作为内群，奇脉茧蜂亚科和折脉茧蜂亚科各一种作为外群，基于形态学和生物学分析建立了53个性状演系列，通过外群比较法，得到一个由二性状和多性状数据矩阵，再用phylip(系统发育推断软件3.6版)处理数据矩阵，最后得到合意树。

The phylogeny of the known 427 genera of Tenthredinoidea of world was reconstructed using the principle and methods of cladistics.

应用支序系统学原理和方法研究了膜翅目叶蜂总科世界已知427属的系统发育关系。

The fields overlap however in the science of phylogenetic systematics – colloquially often called "cladism" or "cladistics"–, where only phylogenetic trees are used to delimit taxa, which represent groups of lineage-connected individuals.

系统发生学与分类学的交互重叠区域是系统发生分类学，常俗称为&分支学说&或&遗传分类学&；在系统发生分类学中，只用系统发生树来定分类的界限，这些分类代表血统相关个体组成的群。
