The Research On The Braconidae In Thousand-Island Lake In China

Braconidae belongs to Hymenoptera,parasitic insect that has a very important ecological role in nature.Braconidae insects a wide range of the world has recorded nearly 10,000 kinds of species;host includes Lepidoptera,Coleoptera,Diptera and other insects,many species of which are very important in natural control of agriculture and forest pests.Also affected by environment.The present paper is to study the species diversity of Braconidae in Thousand-Island Lake in Hangzhou City,Zhejiang Province,29 representative islands were selected for investigate of insects resources.More than 20000 species were collected,of which Hymenoptera was the most abundant.The Braconidae were selected as the research objects.Through the statistics and identification of species and numbers,Insect species,function,genetic diversity provide reference.The general part is mainly about taxonomic history,biology and methods for collecting,identifying and preserving are reviewed.In the systematic accout,7 subfamily,18 genera and 32 species(4 news species)are recognized from Thousand-Island Lake,including 4 new species.Under genus,the generic generic synonym,systematic history,distribution and biology are reviewed.All the species treated in this paper are described and illustrated fully,with figures.Clarifying the distribution of each species on the island,and the time distribution of subfamilies of Braconidae of Thousand-Island Lake.1)Subfamily Cheloninae,5 genera and 9 species,2 new species;2)Subfamily Pambolinae,1 genera and 1 species;3)Subfamily Agathidinae,1 genera and 1 species;4)Subfamily Microgastrinae,4 genera and 8 species5)Subfamily Doryctinae,3 genera and 9 species,2 new species;6)Subfamily Oligoneurus,1 genera and 1 species;7)Subfamily Alysiinae,3 genera and 3 species.
