河南省卢氏地区半翅目昆虫区系研究

Faunal Analysis of Heteroptera(Insecta) from Lushi County,Henan Province

一个地区的昆虫区系研究对当地昆虫种类的多样性和起源进化研究有重要的理论意义,同时还对当地农林害虫的可持续控制及资源昆虫的保护利用产生重要价值。查阅文献发现,卢氏地区的半翅目昆虫区系研究比较薄弱,为此,采用实地野外考察和查阅文献相结合的方法,对河南西部卢氏地区的半翅目(狭义)昆虫区系进行了研究。调查后,卢氏地区的半翅目昆虫种类数量提升至12科33种。从世界动物区系属性上看,古北区和东洋区共有种为25种,占调查总数的75.8%,完全东洋区种类有5种,占调查总数的15.2%,其他类型极少发现,表明卢氏地区半翅目昆虫带有强烈的东洋区与古北区过渡属性。从中国动物区系属性看,华北、华中、华南和西南四区共有种为7种,占调查总数的21.2%;有3个分布类型都包含4种,分别是西南和华中区共同分布型,西南区、东北区、华南区、华中区、华北区共同分布型,西南区、蒙新区、东北区、华南区、华中区、华北区共同分布型,各占调查总数的12.1%。国内昆虫七大区系亚区对卢氏地区半翅目昆虫区系结构的影响作用大小依次是华中区、西南区、华北区、华南区、东北区、蒙新区、青藏区。

Insect faunal research is theoretically significative for study on species diversity andevolutionary history in a target area,and is also practically useful for sustainable management of agricultural pests and exploitation of beneficial insects.Earlier studies showed that in Lushi county of Henan province,only 7 species of 5 families in Heteroptera（Insecta：Hemiptera） were found.For more understanding on Heteroptera fauna of Lushi county,a field collection trip was settled in the earlier summer of 2008.From the hunted specimens and record information of earlier references,thirty-three species,12 families of Heteroptera are recorded in Lushi county up to now.Among them,25 species are Oriental-Palearctic with a 75.8 percent,and 5 species are Oriental with a 15.2 percent.Other distribution types are scarce.This result shows that Lushi county belongs to a typical transitional area between Oriental Region and Palearctic Region in view of Heteroptera.According to zoogeography of China,7 species are distributed jointly in North,Central,South,and Southwest Territory,with a 21.2 percent.Three patterns,which are Central and Southwest Territory jointly distributed pattern,Southwest,Northeast,South,Central and North Territory jointly distributed pattern,and Southwest,Mongolia-Xinjiang,Northeast,South,Central and North Territory jointly distributed pattern,all include 4 species with a 12.1 percent,respectively.The degree of impacts on the Heteropera faunal structure of Lushi county from different faunal regions of China is Central TerritorySouthwest TerritoryNorth TerritorySouth TerritoryNortheast TerritoryMongolia-Xinjiang TerritoryQinghai-Tibet Territory.
