昆明地区蝽次目(半翅目：异翅亚目)昆虫多样性研究

Biodiversity of Pentatomomorpha( Hemiptera: Heteroptera) in Kunming Area

为研究昆明地区半翅目蝽次目昆虫多样性,2007—2011年对蝽次目(Pentatomomorpha)昆虫进行了调查。结果共采集标本1 559头,隶属于11科65属,共87种;其中,蝽科(Pentatomidae)和缘蝽科(Coreidae)昆虫种类和数量最多,分别有29种604头和27种613头;优势种也以两科昆虫为主,分别有8种和5种;龟蝽科(Plataspidae)和网蝽科(Tingidae)种类最少,仅各1种。采用Shannon-Wiener指数和G-F指数对蝽次目昆虫多样性进行了分析。结果表明:蝽科昆虫多样性和均匀度最高,其次是缘蝽科,两科昆虫优势度明显,种群结构相对稳定;龟蝽科和网蝽科,物种多样性和均匀度均最低,种群结构相对不稳定。昆明地区蝽次目昆虫多样性和丰富度指数较高,群落结构相对稳定。

From 2007 to 2011,1 559 specimens of 87 Pentatomomorpha species belonging to 11 families were collected from Kunming,Yunnan Province in China. Of them,the most species and largest number groups were Pentatomidae（ 604 specimens of 29 species） and Coreidae（ 613 specimens of 27species）. The dominant species were also found in Pentatomidae and Coreidae,with 8 and 5,respectively. The lowest species groups were Plataspidae and Tingidae,with only one species,respectively.The diversity of pentatomomorpha species,genera,and families were comprehensively evaluated using Shannon-Wiener index and G-F index. The results indicated that Pentatomidae had the highest biodiversity,evenness index,and dominance index andstability of populative structure,followed by Coreidae,Plataspidae and Tingidae. Pentatomomorpha had high biodiversity and species richness index in Kunming area. Its community structure was relatively stable.
