弹尾目昆虫的

In the collembolan community, Sinella, Onychiurus, Isotomurus are the dominance species, the frequencies are 37.26%, 31.6%,and 21.23%, respectively.2.In the agricultural ecology of Fuyang, the dominant species are Collembola and Acari. Their frequencies are 66.37% and 16.72%, respectively. Liposcelididae, Ceratopogonidae, Chironomidae, Staphylinidae, Nematoda, Enchytraeidae are common species.

弹尾目昆虫对重金属污染的反应，不同的种之间有很大的差别，其中，裸长角属对Cu污染反应不灵敏，陷等属、棘属对Cu污染反应敏感，随着污染程度的加剧，它们的数量明显减少；小等属和长属对Cu、Zn、Cd、Pb等重金属元素的复合污染反应很敏感，而裔符属、球圆属、土属、圆属和鳞长属对重金属复合污染反应很迟钝，在这些重金属复合污染严重的农田中仍能很好地生存繁衍。

Detailed analysis revealed that the majority of the different species identified belonged to 12 Orders of the Insecta, and together these accounted for 58.41% of the total number of species represented. The dominant fauna types in the treated plots belonged to the Coleoptera, Hymenoptera, Acarina, Diptera and Collembola, and together these accounted for 81.44% of the total animal population.

其中昆虫纲物种最为丰富，有12目，占全部种群数的58.41%；鞘翅目、膜翅目、蜱螨目、双翅目和弹尾纲等5种优势类群占土壤动物个体总数的81.44%。5种稀土处理区中，杂食性土壤动物功能团所占的比例均高于植食性功能团所占的比例，且杂食性土壤动物所占的比例依次为对照区﹥La处理区﹥Ce区﹥Pr区﹥Nd区﹥Sm区。

And, we selected some representative species of Collembola and representative groups of Protura, Diplura, Insecta and Arustacean to sequence and analyze their 18S rRNA completely gene sequences, 28S rRNA D6-D7 domain and nearly completely gene sequences to make the studies about the phylogeny relationships of the main families and orders of Collembola, discuss the questions such as the reliability about the new four orders system to Collembola, the monophyletic and ordinal phylogenetic relationships of them and the situation of the special groups, the phylogenetic relationships about Collembola with other groups and the evolution of Hexapod.

同时选取弹尾纲的代表种类和原尾纲、双尾纲、昆虫纲、甲壳动物等节肢动物部分类群，进行了18S rRNA基因全序列和28S rRNA基因D6-D7区以及近全长序列的测定、分析，对弹尾纲重要科属的亲缘关系、进化地位进行分子系统学研究，讨论弹尾纲最新分类系统中四目的确定性、各目单系性、四目的系统关系、特殊类群的分类地位，以及弹尾纲和其它类群之间亲缘关系、六足动物进化等问题。

The soil adopted was typical rice paddy soil in Shanghai region. Soil indication animals included collembolan Folsomia candida, Folsomia fimteria,Sinella curviseta and enchytriedes E.crypticus.

水稻材料为转基因和野生型的粳稻台北309；土壤用标准化处理的上海地区典型水稻土；土壤动物用三种弹尾目昆虫Folsomia candida， Folsomia fimteria，Sinella curviseta和一种线蚓(E.crypticus)。

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。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
