Studies on Systematics of Collembola Collembola belongs to Arthropoda, Hexapoda. It is the most aboundace and cosmopolitan groups of the basal Hexapoda. 686 genera and 7895 species belongs to this class have been reported now from all over the world.

弹尾纲系统分类学研究弹尾纲Collembola，隶属于节肢动物门Arthropoda，六足总纲Hexapoda，是低等六足动物中种类最多、分布最广的一个类群。

One of the paired, flexible, segmented sensory appendages on the head of an insect, a myriapod, or a crustacean functioning primarily as an organ of touch.

触角，触须昆虫、多足纲节肢动物或甲壳类动物头部的一对灵活的管状感觉器官之一，主要为触觉器官

There are a total of 34,782 individuals belonging to 15 orders, 102 families were found in this study. And the dominant groups among them were Myriapoda、Lycosidae、Miridae、Delphacidae、Cicadellidae、Aphidoidea、Margarodidae、Geometridae、Noctuidae、Olethreutidae、Braconidae、Chrysopidae、Coccinellidae.

调查共发现节肢动物个体34782个，分属3纲、15目、102科，其中优势类群主要是多足纲、蛛形纲狼蛛科、半翅目异翅亚目的盲蝽科，同翅目的飞虱科、叶蝉科、蚜科、蚧科，鳞翅目的尺蛾科、夜蛾科、小卷蛾科，膜翅目的小茧蜂科、小蜂总科，脉翅目草蛉科、鞘翅目瓢虫科。

The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.

对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析，结果支持原目、愈腹目的单系性，长角目不形成单系群，支持短角科从愈腹目中分出，但鳞总科和短角目的分类地位有待于深入分析探讨；进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列，以1种多足动物和1种螯肢动物为外群，进行系统关系分析，结果显示：原尾纲、弹尾纲、双尾纲分别为单系群，原尾纲和双尾纲优先聚为一支，然后和弹尾纲构成姐妹群，以上三类又和昆虫聚为一支，支持六足动物的单系性，支持泛甲壳动物，但甲壳动物并未形成单系，其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

Major contents of this paper were: the community structure of zoobenthos, species diversity and production of zoobenthos and so on.

主要结果如下： 1、军山湖计有底栖动物37种，其中瓣鳃纲3科10种；腹足纲7科11种；多毛纲1种；寡毛纲6种；水生昆虫7种；其他2种。

We found 113 insect items in 34 digestive tract contents with eight pieces of intact body or tegmata, i.e., three intact Carabids, three pieces of head, one piece of thorax and one piece of abdomen.

在昆虫纲113件检出物中，个体完整的样品有3件，碎片中头部完整的有3件，出现频度占全部样本数的2.7%；胸部与腹部完整的各1件，各占0.9%；其余各部位碎片残留量，以头部的触角34.5%最多，大颚8.8%次之，胸部以足43.4%最多，其次为翅5.3%，而腹部则以尾毛1.8%最多，产卵管0.9%次之。
