秦岭火地塘林区半翅目昆虫多样性研究

A Study on the Diversity of Hemiptera Insect in Huoditang Forest Farm

对秦岭南坡火地塘林区蒿草丛的半翅目昆虫群落的多样性进行了分析。调查结果表明该地的半翅目昆虫有 8科 6 7种 ,其中盲蝽科 17种、花蝽科 11种、长蝽科 11种、缘蝽科 10种、蝽科 10种、猎蝽科 3种、姬蝽科 3种、龟蝽科 2种。各海拔区群落的多样性测度证实 ,多样性指数随海拔的升高逐渐降低。对 15个海拔区按相似性进行聚类分析、并按DTV指数进行判别 ,可将该地区蒿草丛的半翅目昆虫划分为 3个亚群落 ,各亚群落在垂直分布上的生态位分别是 亚群落 90 0～ 16 0 0 m、 亚群落 170 0～ 180 0 m、 亚群落 190 0～ 2 30 0 m;其中 、 亚群落内部具极强的相似性 ,海拔每升高 10 0 m、

The diversity of Hemiptera insect community in wormwood clumps in Huoditang Forest Farm Qinling Mountains has been studied. The results showed that there were 67 species. Miridae 17 species, Anthocoridae and Lygaeidae 11 species, Coreidae and Pentatamidae 10 species, Reduviidae and Nabidae 3 species, Plataspidae 2 species respectively. The diversity indices decreased with the increasing of altitude. According to cluster analysis and DTV indices differentiation, the Hemiptera groups could be divided into 3 subcommunity. The vertical distributions of different groups were:Ⅰ subcommunity,900～1600m;Ⅱsubcommunity, 1700～1800m; Ⅲ subcommunity, 1900～2300m. Within Ⅰ and Ⅱ subcommunity, there was great internal similarity, but the similarity in Ⅲ subcommunity was different greatly.
