Many entomologist and taxonomist have paid much attention to the studies on phylogeny and systematics of Microgastrinae since the establishment of Microgastrinae by Foerster in 1862. Much headway has been made on the phylogeny and systematics of Microgastrinae , but the dissensions from the entomologist and taxonomist on the species relationship among the genera and tribes of Microgastrinae and the appraisal on Masons classification system are being. A further large number of studies needed to be done to resolve the issue of phylogeny of Microgastrinae.

自Foerster于1862年建立小腹茧蜂亚科Microgastrinae以来，许多的昆虫学家和分类学家对小腹茧蜂亚科Microgastrinae的系统发育和分类做了大量的工作，并取得了一些成果，但是学者之间对于小腹茧蜂亚科族、属间的亲缘关系还存在很大的分歧，显然要充分解决小腹茧蜂亚科系统发育和分类问题，还需要做大量的研究工作。

The Biosystematic Codes index contains the BIOSIS Biosystematic Code for an organism and the corresponding organism classifier discussed in the source document.

生物系统密码的索引包括一种生物体BIOSIS生物密码和在源文档中分类讨论的相应的生物有机体的BIOSIS生物密码，这些生物密码放在括号中，后面跟着分类，分类后面跟着新的分类，这些新分类可以在源分类里讨论时鉴别出来。

Comparison was made between the biological classification system for soil borne plant parasitic nematodes of the Tylenchina suborder and with a nonbiological one (Chinese Soil Taxonomy as an example) in biodiversity characteristics by calculating the power law distribution and Lognormal distribution of the two systems to analyze their similarities and differences.

本文通过计算两种系统分类的幂律和对数正态分布，对土壤植物寄生的线虫类分类体系和非生物系统分类的多样性特征进行了比较，进而分析它们之间的相似性和差异性。
