中国昆虫分类学研究进展

<正> 中国自然条件复杂,昆虫种类繁多,特别是横断山区、青藏高原和云南西双版纳等热带雨林地区昆虫区系丰富多彩,受到国内、外昆虫分类学家的青睐。根据保守估计,中国应有15万种昆虫。中华人民共和国成立前夕我国仅记载20069种昆虫,其中中国人命名的仅204种,绝大多数模式标本及文献资料均散落于国外;分

RECENT ADVANCES IN INSECT SYSTEMATICS IN CHINA

In this paper the main advances of research works in Insect Syste-matics in China are briefly introduced.Publications: "Acta Entomologica Sinica", "Acta Zootaxonomica", "Entomota-xonomica", "Sisozoologica", "Zoological Research", "Scientific Treatise on Syste-matic and Evolutionary Zoology" were published with 2355 papers (including 344mites and ticks). In the past 40 years 8620 new species have been described, from1980 to 1990 the described new species increased more than 500 species each year.A total of about 45 000 insect species have been identified. Yen millions numberof insect specimens are possessed in the whole country. Taxonomists were increa-sing over 500.Three volumes of "Fauna Sinica-Insecta" (Siphonoptera, Hispidae, Drepanidaeand Cyclidiidae) have been published. 39 fascicles of the "Economic Insect Faunaof China" have been published, which included 6226 species (407 of mites andticks). The remaining 18 volumes are still in press. A large of insect iconos, ma-nuals, illustrated handbooks, identification books and monographical books of ag-riculture, forest and medical entomology etc. are very useful for the agriculturaland forest entomologists and technicians to solve the applied problems.In the past 40 years a great deal of comprehansive scientific expeditions havebeen made up by the chinese entomologists, such as in Yunnan, Xingjiang, Xizang,Hengduan Mountain Region, Wuling Mountain Region. Nearly few hundred thou-sands of insect specimens were collected in these places. Most of the results havebeen published, for example "Insect in Xizang", "Insect in Hengduan MountainRegion", "Insect in Wuling Mountain Region" and others. All these informationsupport an argument for the study of insect systematics, phylogeny and zoogeogra-phy.In the field of the theory of insect systematics, Professor Sicien Chen pointedthe following two concepts: (1) the species concept of mutability as well as con-stancy serves as the theoretic kernel of evolutionary systematics, (2) the contrastof newly derived and ancestral characters in character analysis can be used to in-novate on the methodology of evolutionary taxonomy and he proposed a new sys-tem of Chrysomeloidea. On the basis of the ultrastracture of sperms and the chara-cteristics in the post-embryonic stages, Professor W.Y.Yin proposed a new concept of phylogeny in Protura.The study of fossil insects especially from Shanwang, Shangdong (with 272species) are significant for the study of insect evolution. Cladistic analysis, elec-tropherogram, karyotype, insect sound spectrum, analysis of structure of sex phero-mone and computer have long been applied in taxonomy and gained significantresults.
