Systematic Studies On Trichogrammatidae From The Tacheng Region Of Xinjiang

This paper deals with the systematic studies on Trichogrammatidae from the Tacheng region of Xinjiang, China. Based on the examination of about 300 slide-mounted specimens collected by sweeping from about 19 places in this region, 9 genera and 20 species of Trichogrammatidae were described. Among of them, one new species of Aphelinoidea cultrocaudata sp.nov. is reported.The paper comprises three parts: Inroduction, Taxonomic and Observation by scanning electron microscopy (SEM).In General part, the taxonomic history, morphology, biology, hosts records and the application on the biological control etc. are briefly reviewed.In the Taxonomic part, the 9 genera of Trichogrammatidae from the Tacheng region of Xinjiang are diagnosed and keyed for both sexes. In each genus the following information is given: 1) generic synonymy; 2) geographic distribution; 3) diagnosis; 4) the historical review and the present species; 5) hosts; 6) species known from China. When the genus is studied in detailed, a key to the included species from the Tacheng region of Xinjiang (if species more than 2) and full descriptions of each species are proposed, all the species are illustrated in detail. In addition, an illustrated overview of morphology of the family Trichogrammatidae is presented to acquaint readers with basic structures.In the discussion part, the merit and demerit of the expermentation method are described, and the expectation to the research work in the future.A list of the genera and species under each genus treated in this paper are as follows:Trichogrammatidae :1.
